Abstract: Wireless communication devices (UEs) may include multiple receive (RX) chains and associated antennas, and at least one transmit (TX) chain co-located with one of the RX chains. The UE may track instant fading of the antenna gain(s) during reception of packets from an associated access point (AP) device to which the UE intends to transmit packets. The UE may also track long term antenna gain(s), using any packets received at the multiple RX chains within the UE. At a switching occasion, a decision is made by the UE whether to switch antennas. If the instant fading detection is based on packets received no later than a specified time period prior to the switching occasion, then the UE may make the switching decision based on the results of the instant fading tracking. Otherwise, the UE may make the switching decision based on the results of the long term antenna gain tracking.

Abstract: An electronic device provides a capability of distinguishing between human tissue and a non-human object in proximity of a transmission source. In this manner, transmission power adjustments to the transmission source can be made selectively, depending on whether human tissue or a non-human object is detected in the proximity of the RF transmitter. Distinguishing between human tissue and other non-human-tissue objects in proximity of the transmission source provides for selective control of SAR adjustments. Accordingly, an electronic device can avoid certain communication performance reductions introduced by decreases in transmission power effected to comply with SAR standards by reducing transmission power when human tissue is detected in the proximity but not reducing transmission power when a non-human object (but no human tissue) is detected in the proximity.
