Abstract: A method of Transmission Configuration Indication (TCI) state mapping and (Quasi Co Location) (QCL) assumption for PDSCH transmission and reception under multiple transmission point (M-TRP) scheme with PDCCH repetition scheduling is proposed. New rules of TCI state mapping and QCL assumption are defined for PDSCH when there are two CORESETS with two corresponding TCI states under M-TRP scheme with PDCCH repetition scheduling.

For M-TRP PDCCH scheduling M-TRP PDSCH, different TCI state mapping rules are defined, depending on the PDSCH transmission occasions are transmitted in CDM, FDM, or TDM.
