Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more downlink grants while operating in accordance with a first receive state during a threshold number of transmission time intervals (TTIs). The UE may determine a weighting factor for each TTI within the threshold number of TTIs, where the determined weighting factors are based on a spectral efficiency (SPEF) of channel communications between the UE and a base station. The UE may sum a subset of the weighting factors to determine a transition determination value, and may transition from the first receive state to a second receive state based on evaluation of the transition determination value.

Abstract: Aspects are provided which allow a UE to manage a number of antennas in adaptive receive diversity (ARD) based on packet error rate (PER). The UE measures a downlink PER and determines a number of antennas for receiving a downlink transmission based on the measured, downlink PER. The UE measures downlink PER during switching from a fallback state to a steady state in an ARD state machine, and the UE changes a size of a fallback window in the ARD state machine based on the measured, downlink PER. The UE also disables switching from the steady state to the fallback state based on the measured downlink PER. As a result, a balance between UE reception performance and power savings is maximized and improved downlink data throughput is achieved.
