1. An apparatus for wireless communications at a user equipment (UE), comprising:
a first interface configured to:
obtain, from a network device, control signaling indicating a set of relay UEs and a set of cells associated with the network device, wherein the set of cells is for connecting the UE to the network device using the set of relay UEs and the set of relay UEs are configured for relaying communications with the network device;
a processing system configured to:
determine the set of relay UEs based at least in part on the control signaling;
establish communications links with one or more relay UEs of the set of relay UEs based at least in part on the set of relay UEs;
determine an activated subset of relay UEs in the set of relay UEs based at least in part on the communications links; and
determine an activated subset of cells in the set of cells associated with the control signaling and the communications links; and
the first interface or a second interface is configured to:
communicate with the network device via a relay UE of the activated subset of relay UEs and the activated subset of cells.
