Embodiments of the present disclosure relate to methods, devices, and medium for communication. According to embodiments of the present disclosure, the terminal device transmits the assistant information to the network device. The assistant information indicates preferences of the terminal device. The network device determines configuration information based on the assistant information and transmits the configuration information to the terminal device. In this way, the configuration is suitable to the terminal device.

Embodiments of this application provide a communication method, apparatus, and system. The method includes: A network device sends first signaling to a terminal device on a downlink primary component carrier, where the first signaling includes configuration information of a secondary cell; the network device sends second signaling to the terminal device; and the network device determines, based on a channel state information CSI report and/or feedback signaling received from the terminal device, that the terminal device successfully activates the secondary cell.

A downlink reception triggering method, a terminal, and a network-side device are provided. A method on a terminal side includes transmitting a first uplink signal, where the first uplink signal is used to trigger a first downlink reception.

Provided is a method performed by a user equipment (UE) in a wireless communication system, the method including receiving, from a base station, higher layer configuration information including information associated with a sounding reference signal (SRS) resource set and downlink control information (DCI) including scheduling information for a physical uplink shared channel (PUSCH), identifying, from the DCI, a plurality of SRS resource indicators (SRIs) for PUSCH repetition in case that two SRS resource sets are configured by the information associated with the SRS resource set, identifying an SRS resource for the PUSCH repetition based on the plurality of SRIs, determining a power headroom report (PHR) between a first PHR based on actual transmission and a second PHR based on a reference format configured from the higher layer configuration information, and transmitting the determined PHR on the PUSCH.

A method related to physical uplink control channel (PUCCH) cell switching and a user equipment (UE) are provided. The method includes: receiving a radio resource control (RRC) message from a base station; determining a PUCCH cell from the first cell and the second cell according to at least one PUCCH cell pattern; and transmitting the PUCCH transmission on the PUCCH cell during the time resource units. The RRC message includes at least one PUCCH cell pattern associated with multiple cell indexes and a first subcarrier spacing (SCS) associated with a first cell and a second SCS associated with a second cell. Each cell index corresponds to a cell, and the PUCCH cell pattern indicates which cell corresponds to one time resource unit used for PUCCH transmission.

In an 802.11az wireless system, a first station device transmits an NDP PPDU data unit in accordance with a range measurement packet exchange by constructing the NDP PPDU data unit to include an uplink (UL) length field element or a legacy signal length (LLEN) field element derived from a specified number of symbols (N.sub.HE-LTF) and number of repetitions (N.sub.LTF-REP) for the NDP PPDU data unit, and then sending the NDP PPDU data unit to a second STA device, where the values of the UL-length and LLEN field elements are computed as UL-Length=LLEN=10+y+6*Σ.sub.i=1.sup.NUM_USERS((N.sub.LTF-REP(i)+1)*N.sub.HE-LTF(i)), where y=0 for NTB I2R/R2I NDP and TB R2I NDP PPDUs, and where y=3 for TB-I2R NDP PPDUs.

A device may receive sequential digital signals generated by a radio unit based on receipt of sequential radio frequency waveforms provided to ports of the radio unit by a signal generator and analyzer. The device may calculate uplink direction beamforming performance of the radio unit based on the sequential digital signals. The device may provide data identifying the uplink direction beamforming performance for display.

In user equipment for communicating with a base station in a radio communication system including the base station and the user equipment, the user equipment includes a receiver that measures received power of reference signals associated with a plurality of different identification information items, the reference signals being transmitted from the base station, and that selects a specific reference signal based on a measurement result; and a transmitter that transmits a random access signal including a preamble sequence, the preamble sequence corresponding to the identification information item of the reference signal selected by the receiver.

Systems, apparatuses, and methods are described for wireless communications. A base station may determine configuration parameters for a wireless device. The configuration parameters may be based on traffic pattern information received from the wireless device, such as a traffic periodicity, a timing offset, and/or a message size.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a resource grant for at least one sidelink channel, wherein the resource grant indicates an uplink resource for transmitting sidelink transmission acknowledgement messages. The UE may transmit, to the base station and on the uplink resource, an indication of at least one status associated with a listen-before-talk procedure used on the at least one sidelink channel. Numerous other aspects are provided.
