    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, configuration information indicating that the UE is to compress a precoding matrix indicator in connection with channel state information reporting, wherein the precoding matrix indicator is to be compressed based at least in part on a quantization dependency between transmission layers or an orthogonality relationship between the transmission layers, and wherein the configuration information is associated with a type II, higher rank codebook for multiple input multiple output configuration. The UE may transmit, to a base station (BS), the compressed precoding matrix indicator to the base station based at least in part on receiving the configuration information. The UE and BS may use a communication configuration based at least in part on a precoding matrix indicator recovered from the compressed precoding matrix indicator. Numerous other aspects are provided.

    摘要： Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency compression. A method that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration configures the UE for reporting precoding matrix information including, for each layer, a plurality of selected beams L, a plurality of frequency domain compression bases F for the L beams, and a subset of linear combination coefficients associated with the frequency domain compression bases and beams. The UE can determine a number of coefficients to report for a higher rank based on a configured maximum number of coefficients to report for a lower rank.

    摘要： Certain aspects of the present disclosure provide techniques for precoder matrix quantization for compressed channel state information (CSI) feedback. A method for wireless communications by a user equipment (UE) (120a) includes receiving a CSI report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE (120a) to report, for a plurality of selected beams at a plurality of time domain taps, a frequency domain compression basis vector and a plurality of linear combination coefficients associated with the frequency domain compression (805). For each of the beams, the UE (120a) groups the time domain taps into at least first and second groups. The groups each can have zero, one, or more than one time domain taps (810). The UE (120a) quantizes the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping (815).

    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a first decoding result for a plurality of downlink control channels of a diversity enhancement based non-coherent joint transmission communication and a second decoding result for a plurality of data channels corresponding to the plurality of downlink control channels; and selectively provide feedback regarding the first decoding result and feedback regarding the second decoding result, the feedback regarding the first decoding result indicating whether reception of one or more downlink control channels, of the plurality of downlink control channels, is successful, and the feedback regarding the second decoding result indicating whether decoding of a codeword of the plurality of data channels is successful. Numerous other aspects are provided.
