1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive, from a base station (BS) via a controlled discovery procedure, a query to verify a reference signal received power (RSRP) measurement or a quality of service (QOS) associated with a direct connection between the UE and at least one other UE;
establish, using the BS as a layer 2 (L2) relay, the direct connection with the at least one other UE;
switch from the direct connection to an indirect connection between the UE and the at least one other UE via the BS; and
transmit, to an adaptation layer at the BS based on the switch, or receive, from the adaptation layer at the BS based on the switch, one or more PDCP protocol data unit (PDUs) corresponding to L2, the one or more PDCP PDUs being part of a communication between the UE and the at least one other UE.
