Inter-rrh l1-rsrp measurement and tci state switching in fr2 hst deployment

Abstract

Systems and methods provide Layer 1 reference signal received power (L1-RSRP) measurement and transmission configuration indication (TCI) state switching. A cellular communications network determines a plurality transmission reception points (TRPs) configured for high speed train (HST) communication using millimeter wave (mmWave) signals, and generates a synchronization signal block (SSB) index configuration for the plurality TRPs. The SSB index configuration uses non-adjacent SSB indexes between the plurality of TRPs. A user equipment (UE), in response to entering a HST mode, performs L1-RSRP measurement sharing for SSBs received from different TRPs. A scheduling restraint may be used for TCI state switching. Autonomous UL TA adjustment timing may also be used.
