Abstract:
In one novel aspect, multiple TRPs information are provided for REG bundle configuration with PDCCH transmission and reception with multiple transmission points (TRPs). The UE configures a PDCCH associated with a CORESET comprising multiple CCEs, partitions the CORESET into multiple CCE groups associated with corresponding TCI-state, which corresponds to a source TRP, configures multiple resource element group (REG) bundles each with multiple resource elements (REs), and assumes the same precoder applied on PDCCH DMRS when the REs are in the same REG bundle and are associated with the same source TRP, and wherein each source TRP transmits corresponding portion of DCI data mapping to the corresponding first and second CCE group. In one embodiment, the REG bundles are predefined with each comprises only REs associated with the same source TRP. In another embodiment, each CCE group corresponding to a source TRP is indicated for the REG bundle configurations.
