US 12,598,035 B2 · Systems and methods for beam indication for L1/L2 centric inter-cell mobility

Abstract

Systems and methods for beam indication for layer 1/layer 2 (L1/L2) centric inter-cell mobility are described herein. A base station may provide a user equipment (UE) with beam indications, in one or more transmission configuration indication (TCI) states, and may provide different beam indications for different search spaces (SSs), including UE-specific search space (USS) and common search space (CSS) within a same control channel resource set (CORESET). A UE may implicitly select a radio link monitoring (RLM) and beam failure detection (BFD) reference signal (RS) in accord with one or more methods, and in some cases may implicitly select an RLM/BFD RS based on one or more received TCI states or beam indications.

Dependent claims

A method, comprising:

receiving, via radio resource control (RRC) signaling, an indication of at least one common search space (CSS), in a set of one or more CSS associated with a control channel resource set (CORESET), to which a transmission configuration indication (TCI) state received from a network device should be applied;
identifying, at least partly from the indication of the at least one CSS and for a control channel resource set (CORESET), a set of one or more associated CSS and corresponding physical downlink shared channel (PDSCH) to which the TCI state received from the network device should be applied;
receiving the TCI state;
and
applying the TCI state to,
at least one dedicated PDSCH;
and
at least one CSS and corresponding PDSCH in the identified set of one or more CSS and corresponding PDSCH.
