Abstract: A disclosed computer-implemented method may include receiving, from a sensor included in an artificial reality system, data representative of an environment local to the artificial reality system. The disclosed method may also include determining, based on the received data representative of the environment, a probability that an environmental condition will impact a use of a plurality of antennas included in the artificial reality system by the artificial reality system. The disclosed method may also include adjusting, in response to the determined probability that the environmental condition will interfere with the use of the plurality of antennas, the use of the plurality of antennas by the artificial reality system. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A closed-loop power control (CLPC) system is disclosed that includes a first signal path for a first polarization and a second signal path for a second polarization. The first signal path includes a first power amplifier, a first output power detector configured to detect a first output power level of the first power amplifier, and a first processor configured to determine a first analog gain for a first controller and a first gain for a first digital-to-analog converter based on a first accumulated error between the first output power level and a target Effective Isotropically Radiated Power. A second processor is configured to set a first variable gain of a first variable gain amplifier coupled to an input of the first power amplifier. The CLPC can be configured to control the gain of the first signal path separately or as one signal path.

Abstract: Disclosed herein is an approach for improving energy efficiency of a wireless communication device by reducing power distributed to receiver chain circuits (RCCs) based on determining whether the incoming wireless data is to be received and processed by the RCCs within an upcoming time duration. A device can identify a plurality of RCCs for processing data to be received by the device from a network. The device can determine that a first RCC of the plurality of RCCs is to receive the data within a time duration and that a second RCC of the plurality of RCCs is to receive no data within the time duration. The device can cause, responsive to the determination, power to be reduced to the second RCC and not be reduced to the first RCC, within the time duration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may decrease a first value of a transmission power of a first component carrier relative to a second value of a transmission power of a second component carrier based at least in part on the second component carrier carrying control information for the user equipment, wherein the second value of the transmission power of the second component carrier is based at least in part on a first maximum power reduction value identified for carrier aggregation. The user equipment may increase the transmission power of the second component carrier to a third value based at least in part on a second maximum power reduction value identified for single carrier. Numerous other aspects are provided.
