Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information configuring an active bandwidth part (BWP) that does not include a bandwidth associated with one or more of a synchronization signal block (SSB) or a control resource set zero (CS0). The UE may perform, based at least in part on a radio frequency (RF) retune mode, an RF retune to a union bandwidth that covers the active BWP and the bandwidth associated with one or more of the SSB or the CS0. Numerous other aspects are described.
