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.
