Uplink (UL)-based mobility via immediate and delayed keep alive (KA) signals

A method for wireless communication by an access network controller (ANC), comprising:

• selecting, while a user equipment (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE;
• configuring the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE;
• and
• configuring the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.

An apparatus for wireless communication, comprising:

• at least one processor configured to:
• determine the apparatus has failed to decode a first keep alive (KA) signal, from a first transmit/receive point (TRP), during a wake period of a discontinuous receive (DRx) cycle;
• and
• extend the wake period to monitor for a second KA signal, from a second TRP, in response to the determination;
• and
• a memory coupled to the at least one processor.
