Abstract: An apparatus for wireless communication, the apparatus configured to configured to receive a RRC reconfiguration request associated with CA; perform a first set of RRC reconfiguration operations associated with a first set of physical layer parameters in response to the RRC reconfiguration request; transmit, based on completing performing the first set of RRC reconfiguration operations, an RRC reconfiguration complete indication; and perform, after transmitting the RRC reconfiguration complete indication, a second set of RRC reconfiguration operations associated with a second set of parameters other than the first set of physical layer parameters. In certain aspects, the apparatus may be configured to schedule, in response to the RRC reconfiguration request, at least one gap in uplink transmission and downlink reception via a PCC to coincide with one or more time periods based on a known configuration for communication with a network node associated with the carrier aggregation.

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.
