SERVING CELL WITH DISTINCT PCI INDEX PER RRH FOR DL TCI STATE, SPATIAL RELATION, AND UL TCI STATE

Abstract:

Aspects of the disclosure relate to Layer 1/Layer 2-centric inter-cell mobility. Within a serving cell having a plurality of remote radio heads, each remote radio head transmits a referenced signal that includes a PCI index unique to the remote radio head. A user equipment is configured with a beam management function that uses one of the reference signals as a source reference signal for the beam management. The source reference signal is uniquely tied to the corresponding remote radio head through its PCI index.
