Abstract
Certain aspects of the present disclosure relate to techniques and apparatus for improving power efficiency of a wireless device. The techniques may generally include determining a modulation scheme and transmit direction for transmission of a signal using a plurality of antennas, and controlling, separately, at least one amplifier for each of the plurality of antennas, based on the determined transmit direction and modulation scheme.
Claims30
An apparatus for wireless communication, comprising:
- a processing system configured to:
- determine a modulation scheme and transmit direction for transmission of a signal using a plurality of antennas;
- decide whether to set a gain of at least one amplifier for each of a plurality of antennas with different gains based on the modulation scheme;
- separately control the gain of the at least one amplifier for each of the plurality of antennas, based on the determined transmit direction and modulation scheme and further based on the decision of whether to set the gain of the at least one amplifier for each of the plurality of antennas with different gains;
- and
- an interface configured to output the signal for transmission using the plurality of antennas.
