Abstract:
Aspects of the present disclosure provide methods and apparatus for improving UL-based mobility. As described herein, a UE may determine it has failed to decode a first keep alive (KA) signal during a wake period of a discontinuous receive (DRx) cycle and may extend the wake period to monitor for a second KA signal, in response to the determination. An access network controller may select, while a (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE, configure the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE, and configure the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.
