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: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to adaptively transition between modes of an adaptive receive diversity (ARD) antenna management configuration. In some cases, the UE may determine to transition from an ARD disallowed mode to an ARD standby mode in response to receiving a burst of downlink grants. The UE may dynamically update one or more criterion for transitioning between the ARD disallowed mode and the ARD standby mode according to a pattern of received downlink grants. For example, the UE may adjust a threshold quantity of downlink grants which constitutes a burst based on a downlink scheduling rate (DSR) of one or more prior ARD standby durations. In some cases, the UE may identify a fallback condition to transition from the ARD standby mode to the ARD disallowed mode.
