Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a measurement operation to attain multiple measurements to report to a base station. The measurements may correspond to a first number of bits if reported. The UE may compress the measurements using an encoder neural network (NN) to obtain an encoder output indicating the measurements. This encoder output may include a second number of bits that is less than the first number of bits. The UE may report the encoder output to the base station in this compressed form. At the base station, the encoder output may be decompressed according to a decoder NN. Once the base station decompresses the encoder output, the UE and base station may communicate according to the measurements determined from the decompression. In some cases, the base station may perform load redistribution based on the measurements.

Generating a channel state informal ion (CSI) feedback report is provided. A set of reference signals is received (1302). A plurality of entries that are included in the CSI feedback report are computed (1304), where the entries of the CSI feedback report include at leas: a set of coefficients (1306). Each coefficient is associated with at least one or more of a spatial domain basis index, frequency domain basis index, and a layer index (1308). The plurality of entries of the CSI feedback report are arranged (1310) in an order known to both the user equipment and the network entity. The plurality of entries of the CSI feedback report are prioritized using predefined permutations of the indices (1314).

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for determining a set of communication parameters for receiving data transmissions. In some implementations, a method includes receiving a first data transmission sent according to a first communication parameter scheme that includes at least one of a first modulation or a first coding. A second data transmission is received. A second communication parameter scheme of the second transmission is determined. This determination includes identifying a subset of multiple candidate communication parameter schemes determined based on the first communication parameter scheme, identifying, in the second data transmission, a first identifier that corresponds to the second communication parameter scheme, comparing the first identifier to a respective identifier for each communication parameter scheme in the subset, and determining, as the second communication parameter scheme, a communication parameter scheme in the subset that has an identifier that matches the first identifier.

Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, DCI associated with SPS. The apparatus may also identify whether the DCI is EH SPS activation DCI, EH SPS reactivation DCI, data SPS activation DCI, data SPS reactivation DCI, or SPS release DCI, the EH SPS activation DCI and the EH SPS reactivation DCI corresponding to an EH configuration, the data SPS activation DCI and the data SPS reactivation DCI corresponding to a data processing configuration. Additionally, the apparatus may configure an EH component associated with the EH configuration if the DCI is the EH SPS activation DCI or the EH SPS reactivation DCI, or performing data processing associated with the data processing configuration if the DCI is the data SPS activation DCI or the data SPS reactivation DCI.

Methods and apparatuses are described for wireless communications. A first method includes transmitting a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal to a wireless node in a licensed spectrum, and transmitting, concurrently with the transmission of the first OFDMA communications signal, a second OFDMA communications signal to the wireless node in an unlicensed spectrum. A second method includes receiving a first Orthogonal Frequency-Division Multiple Access (OFDMA) communications signal from a wireless node in a licensed spectrum, and receiving, concurrently with the reception of the first OFDMA communications signal, a second OFDMA communication signal from the wireless node in an unlicensed spectrum. A third method includes generating a periodic gating interval for a cellular downlink in an unlicensed spectrum, and synchronizing at least one boundary of the periodic gating interval with at least one boundary of a periodic frame structure associated with a primary component carrier of the cellular downlink.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, on a physical uplink channel, repetitions without a demodulation reference signal (DMRS). The UE may maintain continuity for joint channel estimation of the repetitions without a DMRS during a first time domain window that is based at least in part on a second time domain window associated with joint channel estimation for repetitions with a DMRS. Numerous other aspects are described.

An uplink control channel resource determination method, a terminal, and a network side device are provided, relating to the field of wireless communications. The terminal determines the number N of bits of the uplink control information to be transmitted; the terminal determines, according to a target coding rate and N, the number of first resources; the terminal determines, according to the number of first resources and the number of pre-configured resources, the number of resources actually used; and the terminal uses the number of resources actually used to transmit the uplink control information.

This disclosure provides a method of operating a base station in a cellular telecommunications network, and a base station unit for implementing the method, the base station having a central base station unit and a distributed base station unit, wherein the central base station unit and distributed base station unit communicate over a fronthaul link having a first and second capacity configuration, and the cellular telecommunications network further includes a User Equipment (UE) consuming a service via the base station.

A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver; the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.

At times a UE may have a data transmission that needs to extend beyond a resource grant in an ULRB portion of a slot. The UE may receive resource region reservation information from a base station and determine when to extend an UL transmission from the ULRB portion of a slot into the ULCB portion of the slot based resource region reservation information. The resource region reservation information may indicate ULCB resources which are reserved for PUCCH, PRACH, PUSCH, SRS, or other transmissions. The UE may determine to refrain from extending the data transmission into the ULCB when at least a portion of the data transmission would overlap reserved resources as indicated by the resource region reservation information.
