1. One or more non-transitory computer-readable storage media having instructions that, when executed, cause processing circuitry to:
decode downlink control information (DCI), from a first transmit and receive point (TRP), to determine a first physical downlink shared channel (PDSCH) transmission occasion for a first PDSCH transmission from the first TRP, and a second PDSCH transmission occasion for a second PDSCH transmission from a second TRP, wherein the first PDSCH transmission occasion corresponds to a first resource block group (RBG) set and the second PDSCH transmission occasion corresponds to a second RBG set;
determine, as a default configuration when a scheduling offset is below a threshold reported by a user equipment (UE), a first transmission configuration indicator (TCI) state and a second TCI state, wherein both the first and second TCI states correspond to one codepoint in a TCI field of the DCI;
select a mapping option from a first mapping option and a second mapping option based on a slot, subframe, or frame index of a reference transmission, wherein the first mapping option is to map the first TCI state to the first RBG set and map the second TCI state to the second RBG set and the second mapping option is to map the first TCI state to the second RBG set and map the second TCI state to the first RBG set;
map the first and second TCI states to the first and second RBG sets based on the mapping option; and
decode the first PDSCH transmission and the second PDSCH transmission based on the first and second TCI states as mapped to the first and second RBG sets.
