Abstract

A user equipment (UE) can connect with a network including a plurality of cells. The UE can use layer 1 (L1) and/or layer 2 (L2) signaling to perform L1/L2 centric inter-cell mobility operations among the plurality of cells. Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for selecting an initial beam or default beam in L1 (physical layer) and L2 (medium access control (MAC) layer) based inter-cell mobility. In some aspects, when the UE experiences a beam or radio link failure on a current connection with the network, the UE can fall back to an anchor cell from the plurality of cells and performs a fallback operation on the anchor cell in order to reestablish or maintain communication with the plurality of cells.
