Abstract: Certain aspects of the present disclosure provide techniques for adaptive modulo base selection for non-linear precoding. Aspects provide a method for wireless communications that can be performed by a base station (BS). The BS adaptively selects a modulo base for a data stream for at least one user equipment (UE) in a transmission to one or more UEs. The BS selects the modulo base based on one or more parameters. The BS transmits a signal for at least one UE of the one or more UEs to identify the selected modulo base. The BS performs the transmission to the one or more UEs. The UE receives the transmission from the BS and the signal for the identification of the selected modulo base. Based on the signal, the UE determines the modulo base for at least one data stream in the transmission and decodes the data stream using the modulo base.

Abstract: Certain aspects of the present disclosure provide techniques for layer mapping for multiple transmission reception point (TRP) transmission, for example, for code block group (CBG) based hybrid automatic repeat request (HARQ) acknowledgement feedback in new radio (NR). Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The UE receives one or more transport blocks (TBs) from a plurality of TRPs. Each of the one or more TBs comprises a plurality of CBs. For one or more of the plurality of CBs, all bits of the CB are received from a same TRP. The UE decodes the one or more TBs.

Abstract: Techniques and apparatus for configuring transmission rank and/or precoder(s) to support uplink non-codebook based transmission are provided. One technique includes receiving sounding reference signal (SRS) resource(s) from a user equipment (UE), where each SRS resource is associated with one or more precoded ports. At least one of a transmission rank or a set of precoders is determined based on the SRS resource(s). An indication of at least one of the SRS resource(s) is signaled to the UE. The UE uses the indication of the at least one of the SRS resource(s) to send an uplink transmission.
