Methods, systems, and devices for wireless communications are described that provide for antenna selection at a user equipment (UE). The UE may have a set of available antennas for uplink and downlink communications, and may select a first subset of antennas for uplink communications and a second subset of antennas for downlink communications. The first subset of antennas may be based on one or more uplink metrics, and the second subset of antennas may be based on the first subset of antennas and one or more downlink channel metrics, traffic amounts, or any combinations thereof.

Antenna selection techniques for uplink and downlink wireless communications

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may communicate with a base station using multiple receivers and receive an indication from the base station to activate a second bandwidth part of a set of bandwidth parts configured for the UE. In response to the indication, the UE may switch from operating in a first bandwidth part to operating in the second bandwidth part and adjust a quantity of active receivers at the UE based on switching from operating in the first bandwidth part to operating in the second bandwidth part. Additionally or alternatively, the UE may adjust the quantity of active receivers at the UE based on monitoring for downlink grants from the base station.

Receiver adjustment for wireless communication

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a first configuration indicating for the UE to communicate with the base station using a set of receive ports. The UE may transmit, according to the first configuration in a first time interval associated with a first power state of the UE, sounding reference signals (SRSs) on a set of transmit ports corresponding to the set of receive ports. The UE may then communicate using less than all of the set of transmit ports for the SRSs based on determining to operate in a reduced power state. The UE may then receive, based on communicating using less than all of the set of transmit ports for the SRSs, a second configuration indicating for the UE to communicate with the base station using a first subset of receive ports.
