Abstract: Wireless communication between a mobile device or user equipment (UE) having a plurality of antennas and a base station includes signaling a reduced capability with respect to a number of antennas used for an uplink transmission. To reduce UE power consumption, e.g., when a battery is low and/or when a throughput is low, a UE may signal a lower capability, such as one that uses fewer antennas than the UE has available for an uplink transmission. The UE may then deactivate RF circuitry coupled to one or more antennas to reduce power consumption without significantly reducing performance.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a New Radio (NR) cell, an Internet protocol multimedia subsystem (IMS) configuration message. The UE may receive, from the NR cell, an instruction to fallback to a legacy cell. The UE may store a response to the IMS configuration message based at least in part on receiving the instruction to fallback. The UE may transmit, to the legacy cell and before transmitting another IMS message, the response to the IMS configuration message. Numerous other aspects are described.
