Abstract: Certain aspects of the present disclosure provide techniques for downlink and/or uplink beam management for full-duplex communications. An example method generally includes receiving, from a wireless node, a RS resource configuration indicating interference RS resources associated with interference reference signal transmissions; monitoring interference RSs via the interference RS resources; for each of the interference RS resources, determining a reception beam based at least in part on the monitored more interference RSs corresponding to the interference RS resources; receiving control signaling, from the second wireless node, indicating QCL information, which also indicates to either refrain from using any monitored interference RS resource in determining spatial reception parameters or identify at least one monitored interference RS resource to use in determining the spatial reception parameters; and determining the spatial reception parameters in accordance with the control signaling.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).

Abstract: 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.

Abstract: 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).
