METHOD AND APPARATUS FOR DOWNLINK AND UPLINK MULTI-BEAM OPERATION

原文（中国語）

A method for operating a user equipment (UE) comprises receiving configuration information including multiple transmission configuration indicator (TCI) states, and receiving a beam indication indicating a TCI state from the multiple TCI states. The TCI state indicates a beam for each of N entities (E, E, . . . E), and the TCI state comprises a TCI state ID and up to N+1 components (A, A, A, . . . , A), where Acomprises common components for all entities, and for each n∈{1,2, . . . ,N}, Acomprises specific components for entity E, and components Aand Atogether indicate the beam for entity E. The method includes determining the beam for each of N entities (E, E, . . . E) indicated by the TCI state, and transmitting an uplink (UL) transmission or receiving a downlink (DL) transmission based on the beam for each of N entities (E, E, . . . E).
