Embodiment 1

[0191] FIG. 1 is a flowchart showing a method performed by user equipment according to Embodiment 1 of the present invention.

[0192] In Embodiment 1 of the present invention, the steps performed by user equipment (UE) comprise:

[0193] In step 101, configuration information of a parameter related to generation of an OFDM baseband signal of a 5G sidelink physical channel or signal (for example, whether the parameter has been configured or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0194] A parameter sl-FreqOffset0 used to indicate a frequency offset.

[0195] For example, the configuration information of the parameter sl-FreqOffset0 is acquired via DCI.

[0196] For another example, the configuration information of the parameter sl-FreqOffset0 is acquired via a MAC CE.

[0197] For another example, the configuration information of the parameter sl-FreqOffset0 is acquired via RRC signaling. For example, the configuration information of the parameter sl-FreqOffset0 contained in a master information block (such as an MIB-SL transmitted on a PSBCH) of a 5G sidelink is acquired.

[0198] For another example, the configuration information of the parameter sl-FreqOffset0 is pro-defined, for example, sl-FreqOffset0=0.

[0199] For another example, the configuration information of the parameter sl-FreqOffset0 is acquired via pre-con figured information. For example, the configuration information of the parameter sl-FreqOffset0 contained in pre-configured information (such as SL-Preconfiguration) of the 5G sidelink is acquired.

[0200] For another example, if the configuration information of the parameter sl-FreqOffset0 contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-FreqOffset0 contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter sl-FreqOffset0 contained in the master information block of the 5G sidelink is used (that is, the configuration information of the parameter sl-FreqOffset0 contained in the pre-defined or pre-configured information of the 5G sidelink is discarded).

[0201] For another example, if both the configuration information of the parameter sl-FreqOffset0 contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-FreqOffset0 contained in the pre-defined or pre-configured information of the 5G sidelink are acquired, the configuration information of the parameter sl-FreqOffset0 contained in the pre-defined or pre-configured information of the 5G sidelink is used (that is, the configuration information of the parameter sl-FreqOffset0 contained in the master information block of the 5G sidelink is discarded).

[0202] In step 103, the OFDM baseband signal of the 5G sidelink physical channel or signal is generated according to the configuration information of the parameter related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal. For example, the OFDM baseband signal of the 5G sidelink physical channel or signal may be expressed, by using a time-continuous signal as s.sub.l.sup.(p,μ)(t), as

[00003]$s_l^{\left(p,\mu \right)}\left(t\right)=\underset{k=0}{\overset{N_{\mathrm{grid}}^{\mathrm{size},\mu }{N}_{\mathrm{sc}}^{\mathrm{RB}}-1}{.Math.}}{\alpha }_{k,l}^{\left(p,\mu \right)}.Math.e^{j2\pi \left(k+k_0^{\mu }-N_{\mathrm{grid}}^{\mathrm{size},\mu }{N}_{\mathrm{sc}}^{\mathrm{RB}}/2\right)\Delta f\left(t-N_{\mathrm{CP},l}^{\mu }{T}_c-t_{\mathrm{start},l}^{\mu }\right)}$

[0203] where [0204] p is an antenna port; [0205] μ is the subcarrier spacing configuration, and Δf is its corresponding subcarrier spacing, see Table 1; [0206] l is the number of an OFDM symbol in one subframe, l∈{0, 1, . . . , N.sub.slot.sup.subframe,μN.sub.symb.sup.slot−1}; [0207] t.sub.start,l.sup.μ≤t<t.sub.start,l.sup.μ+(N.sub.u.sup.μ+N.sub.CP,l.sup.μ)T.sub.c; [0208] for l=0, t.sub.start,l.sup.μ=0; [0209] for l≠0, t.sub.start,l.sup.μ=t.sub.start,l-1.sup.μ+(N.sub.u.sup.μ+N.sub.CP,l-1.sup.μ)T.sub.c; [0210] N.sub.u.sup.μ=2048κ.Math.2.sup.−μ; [0211] for an extended cyclic prefix, N.sub.CP,l.sup.μ=512κ.Math.2.sup.−μ; [0212] for a normal cyclic prefix, and l=0 or l=7.Math.2.sup.μ, N.sub.CP,l.sup.μ=144κ.Math.2.sup.−μ+16κ; [0213] for a normal cyclic prefix, and l≠0 and l≠7.Math.2.sup.μ, N.sub.CP,l.sup.μ=144κ.Math.2.sup.−μ; and [0214] k.sub.0.sup.μ represents the frequency offset, which is determined by the parameter sl-FreqOffset0, or is directly given by the parameter sl-FreqOffset0.

[0215] Embodiment 1 of the present invention is suitable for UE to generate an OFDM baseband signal of a 5G sidelink physical channel or signal. The 5G sidelink physical channel or signal may include a PSSS, an SSSS, a PSBCH, a PSCCH, a PSDCH, a PSSCH, etc.

[0216] As described above, the method performed by the user equipment in Embodiment 1 of the present invention includes: acquiring configuration information of a parameter related to generation of an OFDM baseband signal of a sidelink physical channel or signal; and generating, according to the acquired configuration information of the parameter, the OFDM baseband signal of the sidelink physical channel or signal, where the parameter includes a frequency offset determining parameter used to determine a frequency offset. The frequency offset determining parameter may be, for example, a parameter for indicating the frequency offset.

[0217] According to the foregoing method, since the parameter related to the generation of the OFDM baseband signal of the sidelink physical channel or signal acquired by the UE includes the frequency offset determining parameter used to determine the frequency offset, even UE out of network coverage can correctly generate the OFDM baseband signal of the sidelink according to the acquired frequency offset determining parameter. In this way, for example, in case that sets of subcarrier spacing configurations used by the 5G sidelink and a 5G uplink or supplementary uplink are different, the UE can still correctly generate the OFDM baseband signal of the 5G sidelink, so as to share a carrier in the 5G sidelink and the 5G uplink or supplementary uplink, thereby improving the utilization efficiency of communication resources.

[0220] In step 201, configuration information of a parameter related to generation of an OFDM baseband signal of a 5G sidelink physical channel or signal (for example, whether the parameter has been configured or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-con figured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0221] a parameter sl-subcarrierSpacing0 used to indicate a reference subcarrier spacing configuration; and [0222] a configuration parameter used to indicate a reference resource grid corresponding to the reference subcarrier spacing configuration, which, for example, includes: [0223] a parameter sl-offsetToCarrier0 used to indicate a number of a lowest-numbered common resource block of the reference resource grid; and [0224] a parameter sl-carrierBandwidth0 used to indicate the quantity of frequency domain resource blocks of the reference resource grid.

For example, the configuration information of one or a plurality of the parameters sl-subcarrierSpacing0, sl-offsetToCarrier0, and sl-carrierBandwidth0 contained in pre-configured information (such as SL-Preconfiguration) of the 5G sidelink is acquired.

[0233] For another example, if the configuration information of one or a plurality of the parameters sl-subcarrierSpacing0, sl-offsetToCarrier0, and sl-carrierBandwidth0 contained in the master information block of the 5G sidelink and the configuration information of one or a plurality of the parameters sl-subcarrierSpacing0, sl-offsetToCarrier0, and sl-carrierBandwidth0 contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the corresponding parameter contained in the master information block of the 5G sidelink is used (that is, the configuration information of the corresponding parameter in the pre-defined or pre-configured information of the 5G sidelink is discarded).

[0234] For another example, if the configuration information of one or a plurality of the parameters sl-subcarrierSpacing0, sl-offsetToCarrier0, and sl-carrierBandwidth0 contained in the master information block of the 5G sidelink and the configuration information of one or a plurality of the parameters sl-subcarrierSpacing0, sl-offsetToCarrier0, and sl-carrierBandwidth0 contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter contained in the pre-defined or pre-configured information of the 5G sidelink is used (that is, the configuration information of the corresponding parameter contained in the master information block of the 5G sidelink is discarded).

[0235] In step 203, the OFDM baseband signal of the 5G sidelink physical channel or signal is generated according to the configuration information of the parameter related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal, for example, the OFDM baseband signal of the 5G sidelink physical channel or signal may be expressed, by using a time-continuous signal s.sub.l.sup.(p,μ)(t), as

[00004]$s_l^{\left(p,\mu \right)}\left(t\right)=\underset{k=0}{\overset{N_{\mathrm{grid}}^{\mathrm{size},\mu }{N}_{\mathrm{sc}}^{\mathrm{RB}}-1}{.Math.}}{\alpha }_{k,l}^{\left(p,\mu \right)}.Math.e^{j2\pi \left(k+k_o^{\mu }-N_{\mathrm{grid}}^{\mathrm{size},\mu }{N}_{\mathrm{sc}}^{\mathrm{RB}}/2\right)\Delta f\left(t-N_{\mathrm{CP},l}^{\mu }{T}_c-t_{\mathrm{start},l}^{\mu }\right)}$

[0236] Regarding the items in the above calculation formula, the description of the same items as those in Embodiment 1 is omitted.

[0237] Where [0238] k.sub.0.sup.μ is calculated by using the following formula:

k.sub.0.sup.μ=(N.sub.grid.sup.start,μ+N.sub.grid.sup.size,μ/2)N.sub.sc.sup.RB−(N.sub.grid.sup.start,μ.sup.0+N.sub.grid.sup.size,μ.sup.0/2)N.sub.sc.sup.RB2.sup.μ.sup.0.sup.−μ, [0239] where [0240] μ.sub.0 is determined by the parameter sl-subcarrierSpacing0, or is directly given by the parameter sl-subcarrierSpacing0; [0241] N.sub.grid.sup.start,μ.sup.0 is determined by the parameter sl-offsetToCarrier0, or is directly given by the parameter sl-offsetToCarrier0: and [0242] N.sub.grid.sup.size,μ.sup.0 is determined by the parameter sl-carrierBandwidth0, or is directly given by the parameter sl-carrierBandwidth0;

[0247] In step 301, configuration information of a parameter related to generation of an OFDM baseband signal of a 5G sidelink physical channel or signal (for example, whether the parameter has been configured or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0248] a parameter sl-subcarrierSpacing used to indicate a subcarrier spacing configuration used by the OFDM baseband signal of the 5G sidelink physical channel or signal; and [0249] a configuration parameter used to indicate a resource grid corresponding to the subcarrier spacing configuration, which, for example, includes: [0250] a parameter sl-offsetToCarrier used to indicate a number of a lowest-numbered common resource block of the resource grid; and [0251] sl-carrierBandwidth used to indicate the quantity of frequency domain resource blocks of the resource grid.

[0262] In step 303, the OFDM baseband signal of the 5G sidelink physical channel or signal is generated according to the configuration information of the parameter related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal.

[0272] In step 401, configuration information of a parameter related to an uplink carrier or a supplementary uplink carrier (for example, whether the parameter has been configured, or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0273] configuration information of a waveform numerology related to the uplink carrier or the supplementary uplink carrier and a corresponding resource grid, which is configured, for example, via a Frequency InfoUL-SIB IE or a parameter scs-SpecificCarrierList in the Frequency InfoUL-SIB IE.

[0274] In step 403, configuration information of a parameter related to generation of an OFDM baseband signal of a 5G sidelink physical channel or signal is determined according to the configuration information of the parameter related to the uplink carrier or the supplementary uplink carrier. [0275] For example, a reference subcarrier spacing configuration sl-subcarrierSpacing0 is determined according to the maximum value μ.sub.0 in all subcarrier spacing configurations configured in the parameter scs-SpecificCarrierList, and a number sl-offsetToCarrier0 of a lowest-numbered common resource block of a resource grid corresponding to the reference subcarrier spacing configuration and the quantity sl-carrierBandwidth0 of frequency domain resource blocks of the resource grid corresponding to the reference subcarrier spacing configuration are respectively determined according to a number N.sub.grid.sup.start,μ.sup.0 of a lowest-numbered common resource block and the quantity N.sub.grid.sup.start,μ.sup.0 of frequency domain resource blocks of a resource grid corresponding to μ.sub.0.

[0276] In step 405, system information, for example, an MIB-SL, related to a 5G sidelink is transmitted. The system information related to the 5G sidelink includes configuration information of one or a plurality of the following parameters: [0277] the reference subcarrier spacing configuration sl-subcarrierSpacing0; [0278] the number sl-offsetToCarrier0 of the lowest-numbered common resource block of the resource grid corresponding to the reference subcarrier spacing configuration; and [0279] the quantity sl-carrierBandwidth0 of frequency domain resource blocks of the resource grid corresponding to the reference subcarrier spacing configuration.

[0280] According to the method in Embodiment 4 above, since the determined parameter related to the generation of the OFDM baseband signal of the sidelink physical channel or signal includes the frequency offset determining parameter used to determine the frequency offset, and the system information includes the configuration information of the frequency offset determining parameter, the UE receiving the system information can correctly generate, for example, an OFDM baseband signal of a 5G sidelink according to the configuration information of the frequency offset determining parameter, so as to share a carrier in the 5G sidelink and the 5G uplink or supplement uplink, thereby improving the utilization efficiency of communication resources.

Embodiment 5

[0281] FIG. 5 is a flowchart showing a method performed by user equipment according to Embodiment 5 of the present invention.

[0282] In Embodiment 5 of the present invention, the user equipment (UE) performs the following steps:

[0283] In step 501, configuration information of a parameter related to an uplink carrier or a supplementary uplink carrier (for example, whether the parameter has been configured, or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0284] configuration information of a waveform numerology related to the uplink carrier or the supplementary uplink carrier and a corresponding resource grid, which is configured, for example, via a FrequencyInfoUL-SIB IE or a parameter scs-SpecificCarrierList in the FrequencyInfoUL-SIB IE.

[0285] In step 503, configuration information of a parameter related to generation of an OFDM baseband signal of a 5G sidelink physical channel or signal is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0286] a subcarrier spacing configuration μ used by the 5G sidelink physical channel or signal, and a number N.sub.grid.sup.start,μ of a lowest-numbered common resource block and the quantity N.sub.grid.sup.size,μ of frequency domain resource blocks of a resource grid corresponding to μ.

[0287] In step SOS, configuration information of other parameters related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal is determined according to the configuration information of the parameter related to the uplink carrier or the supplementary uplink carrier and the configuration information of the parameter related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal. The other parameters related to the generation of the OFDM baseband signal of the 5G sidelink physical channel or signal include: [0288] frequency offset k.sub.0.sup.μ

[0289] For example, the value of the frequency offset k.sub.0.sup.μ calculated, according to the maximum value μ.sub.0 in all subcarrier spacing configurations configured in the parameter scs-SpecificCarrierList, a number N.sub.grid.sup.start,μ.sup.0 and of a lowest-numbered common resource block and the quantity N.sub.grid.sup.size,μ.sup.0 of frequency domain resource blocks of a resource grid corresponding to μ.sub.0, the subcarrier spacing configuration μ used by the 5G sidelink physical channel or signal, and the number N.sub.grid.sup.start,μ of the lowest-numbered common resource block and the quantity N.sub.grid.sup.size,μ of frequency domain resource blocks of the resource grid corresponding to μ, via the following formula:

k.sub.0.sup.μ=(N.sub.grid.sup.start,μ+N.sub.grid.sup.size,μ/2)N.sub.sc.sup.RB−(N.sub.grid.sup.start,μ.sup.0+N.sub.grid.sup.size,μ.sup.0/2)N.sub.sc.sup.RB2.sup.μ.sup.0.sup.−μ

[0290] and the value of the frequency offset parameter sl-FreqOffset0 is determined according to the value of k.sub.0.sup.μ, for example, sl-FreqOffset0=k.sub.0.sup.μ.

[0291] In step 507, system information, for example, an MIB-SL, related to a 5G sidelink is transmitted. The system information related to the 5G sidelink includes configuration information of the following parameter: [0292] frequency offset sl-FreqOffset0.

[0293] According to the method in Embodiment 5 above, as in Embodiment 4, this enables the UE receiving the system information to correctly generate, for example, an OFDM baseband signal of a 5G sidelink, so as to share a carrier in the 5G sidelink and a 5G uplink or supplementary uplink, thereby improving the utilization efficiency of communication resources.

Embodiment 6

[0294] FIG. 6 is a flowchart showing a method performed by user equipment according to a Embodiment 6 of the present invention.

[0295] In Embodiment 6 of the present invention, the user equipment (UE) performs the following steps:

[0296] In step 601, configuration information of a parameter related to a 5G sidelink carrier configuration (for example, whether the parameter has been configured or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0297] A center frequency (i.e., “point A”) of sub-carrier 0 of common resource block 0, which is configured, for example, by using a parameter sl-absoluteFrequencyPointA, and for example, its type is ARFCN-ValueNR.

[0298] For example, the configuration information of the parameter sl-absoluteFrequencyPointA is acquired via DCI.

[0299] For another example, the configuration information of the parameter sl-absoluteFrequencyPointA is acquired via a MAC CE.

[0300] For another example, the configuration information of the parameter sl-absoluteFrequentyPointA is acquired via RRC signaling. For example, the configuration information of the parameter sl-absoluteFrequencyPointA contained in a master information block (such as an MIB-SL transmitted on a PSBCH) of a 5G sidelink is acquired.

[0301] For another example, the configuration information of the parameter sl-absoluteFrequencyPointA is pre-defined.

[0302] For another example, the configuration information of the parameter sl-absoluteFrequencyPointA is acquired via pre-con figured information. For example, the configuration information of the parameter sl-absoluteFrequencyPointA contained in pre-configured information (such as SL-Preconfiguration) of the 5G sidelink is acquired.

[0303] For another example, if the configuration information of the parameter sl-absoluteFrequencyPointA contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-absoluteFrequencyPointA contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter sl-absoluteFrequencyPointA contained in the master information block of the 5G sidelink is used (that is, the configuration information of the parameter sl-absoluteFrequencyPointA contained in the pre-defined or pre-configured information of the 5G sidelink is discarded).

[0304] For another example, if the configuration information of the parameter si-absoluteFrequencyPointA contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-absoluteFrequencyPointA contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter sl-absoluteFrequencyPointA contained in the pre-defined or pre-configured information of the 5G sidelink is used (that is, the configuration information of the parameter sl-absoluteFrequencyPointA contained in the master information block of the 5G sidelink is discarded).

[0305] In step 603, an RF reference frequency of the corresponding 5G sidelink carrier is determined according to the configuration information of the parameter related to the the 5G sidelink carrier configuration.

[0306] For example, the RF reference frequency of the 5G sidelink carrier is determined according to the parameter sl-absoluteFrequencyPointA and, for example, the reference subcarrier spacing configuration μ.sub.0 and the number N.sub.grid.sup.start,μ.sup.0 of the lowest-numbered common resource block and the quantity N.sub.grid.sup.size,μ.sup.0 of frequency domain resource blocks of the resource grid corresponding to μ.sub.0. For example, if N.sub.grid.sup.size,μ.sup.0 mod=0, the RF reference frequency of the 5G sidelink carrier corresponds to a center frequency of subcarrier 0 in a common resource block with a number of

[00006]$N_{\mathrm{grid}}^{\mathrm{start},{\mu }_o}+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},{\mu }_o}}{2}.Math.,$

that is, the RF reference frequency of the 5G sidelink carrier is equal to the frequency indicated by the parameter sl-absoluteFrequencyPointA plus bandwidth (using μ.sub.0 as the subcarrier spacing configuration) occupied by

[00007]$N_{\mathrm{grid}}^{\mathrm{start},{\mu }_o}+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},{\mu }_o}}{2}.Math..Math.N_{\mathrm{sc}}^{\mathrm{RB}}$

subcarriers; if N.sub.grid.sup.size,μ.sup.0 mod 2=1, the RF reference frequency of the 5G sidelink carrier corresponds to a center frequency of subcarrier 6 in a common resource block with a number of

[00008]$N_{\mathrm{grid}}^{\mathrm{start},{\mu }_0}+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},{\mu }_0}}{2}.Math.,$

that is, the RF reference frequency of the 5G sidelink carrier is equal to the frequency indicated by the parameter sl-absoluteFrequencyPointA plus bandwidth (using pa as the subcarrier spacing configuration) occupied by

[00009]$\left(N_{\mathrm{grid}}^{\mathrm{start},{\mu }_0}+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},{\mu }_0}}{2}.Math.\right).Math.N_{\mathrm{sc}}^{\mathrm{RB}}+6$

subcarriers.

[0307] For another example, the RF reference frequency of the 5G sidelink carrier is determined according to the parameter sl-absoluteFrequencyPointA, the frequency offset k.sub.0.sup.μ as determined, for example, in the steps in Embodiment 1 or Embodiment 2, and the subcarrier spacing configuration μ used by the OFDM baseband signal of the 5G sidelink physical channel or signal and the number N.sub.grid.sup.start,μ of the lowest-numbered common resource block and the quantity N.sub.grid.sup.size,μ of frequency domain resource blocks of the resource grid corresponding to μ as determined, for example, in the steps in Embodiment 3. For example, if N.sub.grid.sup.size,μ mod 2=0, the RF reference frequency of the 5G sidelink carrier corresponds to a frequency offsetting −k.sub.0.sup.μ subcarriers from a center frequency of subcarrier 0 in a common resource block with a number of

[00010]$N_{\mathrm{grid}}^{\mathrm{start},\mu }+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},\mu }}{2}.Math.,$

that is, the RF reference frequency of the 5G sidelink carrier is equal to the frequency indicated by the parameter sl-absoluteFrequencyPointA plus bandwidth (using μ as the subcarrier spacing configuration) occupied by

[00011]$\left(N_{\mathrm{grid}}^{\mathrm{start},\mu }+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},\mu }}{2}.Math.\right).Math.N_{\mathrm{sc}}^{\mathrm{RB}}-k_0^{\mu }$

subcarriers; if N.sub.grid.sup.size,μ mod 2=1, the RF reference frequency of the 5G sidelink carrier corresponds to a frequency offsetting −k.sub.0.sup.μ subcarriers from a center frequency of subcarrier 6 in a common resource block with a number of

[00012]$N_{\mathrm{grid}}^{\mathrm{start},\mu }+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},\mu }}{2}.Math.,$

that is, the RF reference frequency of the 5G sidelink carrier is equal to the frequency indicated by the parameter sl-absoluteFrequencvPointA plus bandwidth (using μ as the subcarrier spacing configuration) occupied by

[00013]$\left(N_{\mathrm{grid}}^{\mathrm{start},\mu }+.Math.\frac{N_{\mathrm{grid}}^{\mathrm{size},\mu }}{2}.Math.\right).Math.N_{\mathrm{sc}}^{\mathrm{RB}}+6-k_0^{\mu }$

subcarriers.

[0308] According to the method in Embodiment 6 above, since the determined configuration information of the parameter related to the 5G sidelink carrier configuration includes the parameter for determining the center frequency of subcarrier 0 of common resource block 0, this enables the UE acquiring the parameter to correctly determine the RF reference frequency of the 5G sidelink carrier, so as to correctly implement operations such as modulation and upconversion.

Embodiment 7

[0309] FIG. 7 is a flowchart showing a method performed by user equipment according to Embodiment 7 of the present invention.

[0310] In Embodiment 7 of the present invention, the user equipment (UE) performs the following steps:

[0311] In step 701, configuration information of a parameter related to a 5G sidelink carrier configuration (for example, whether the parameter has been configured, or a value configured for the parameter) is acquired. For example, the configuration information of the parameter is acquired from pre-defined information or pre-configured information, or the configuration information of the parameter is acquired from a base station, or the configuration information of the parameter is acquired from other UE. The parameter includes: [0312] an instruction to perform 7.5 kHz frequency shifting on sidelink transmission, for example, to perform configuration via a parameter sl-frequencyShift7p5 khz.

[0313] For example, the configuration information of the parameter sl-frequencyShift7p5 khz is acquired via DCI.

[0314] For another example, the configuration information of the parameter sl-frequencyShift7p5 khz is acquired via a MAC CE.

[0315] For another example, the configuration information of the parameter sl-frequencyShift7p5 khz is acquired via RRC signaling. For example, the configuration information of the parameter sl-frequencyShift7p5 khz contained in a master information block (such as an M/B-SL transmitted on a PSBCH) of a 5G sidelink is acquired.

[0316] For another example, the configuration information of the parameter sl-frequencyShift7p5 khz is pre-defined, for example, sl-frequencyShift7p5 khz is not configured.

[0317] For another example, the configuration information of the parameter sl-frequencyShift7p5 khz is acquired via pre-configured information. For example, the configuration information of the parameter sl-frequencyShift7p5 khz contained in pre-configured information (such as SL-Preconfiguration) of the 5G sidelink is acquired.

[0318] For another example, if the configuration information of the parameter sl-frequencyShift 7p5 khz contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-frequencyShift7p5 khz contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter sl-frequencyShift7p5 khz contained in the master information block of the 5G sidelink is used (that is, the configuration information of the parameter sl-frequencyShift7p5 khz contained in the pre-defined or pre-configured information of the 5G sidelink is discarded).

[0319] For another example, if the configuration information of the parameter sl-frequencyShift7p5 khz contained in the master information block of the 5G sidelink and the configuration information of the parameter sl-frequencyShift7p5 khz contained in the pre-defined or pre-configured information of the 5G sidelink are both acquired, the configuration information of the parameter sl-frequencyShift7p5 khz contained in the pre-defined or pre-configured information of the 5G sidelink is used (that is, the configuration information of the parameter sl-frequencyShift7p5 khz contained in the master information block of the 5G sidelink is discarded).

[0320] In step 703, a shift Δ.sub.shift of an RF reference frequency of the corresponding 5G sidelink carrier is determined according to the configuration information of the parameter related to the 5G sidelink carrier configuration.

[0321] For example, if the parameter frequencyShift7p5 khz is not configured, the shift Δ.sub.shift=0 kHz; if the parameter frequencyShift7p5 khz is configured, the shift Δ.sub.shift=7.5 kHz.

[0322] In step 705, the shift Δ.sub.shift is applied to the RF reference frequency of the 5G sidelink carrier, for example:

F.sub.REF_shift=F.sub.REF+Δ.sub.shift.

[0323] Optionally, Embodiment 7 of the present invention is only applied to an SUL frequency band and frequency bands n1, n2, n3, n5, n7, n8, n20, n28, n66, and n71.

[0324] According to the method in Embodiment 7 above, since the determined configuration information of the parameter related to the 5G sidelink carrier configuration includes the parameter used to instruct to perform 7.5 kHz frequency shifting on the sidelink transmission, this enables the UE acquiring the parameter to correctly determine the RF reference frequency of the 5G sidelink carrier, so as to correctly implement operations such as modulation and upconversion.

[0325] Any one of the foregoing embodiments and implementations may be applied to one 5G sidelink carrier, or may be applied to a plurality of 5G sidelink carriers respectively.
