1. A method comprising:
determining a physical resource block (PRB) bundling size based on a downlink control information (DCI) message that provides scheduling information for a physical downlink shared channel (PDSCH), wherein:
determining the PRB bundling size comprises determining whether the PRB bundling size is wideband, and

of PRBs in a plurality of PDSCH transmissions are assigned to a first transmission configuration indicator (TCI) state and the remaining

of the PRBs in the plurality of PDSCH transmissions are assigned to a second TCI state, and
nPRB is the total number of allocated PRBs for a user equipment (UE);
receiving a plurality of PDSCH transmissions from multiple transmission and reception points (TRPs) that are transmitted in accordance with the DCI message; and
decoding one or more of the plurality of the PDSCH transmissions based at least on the determination whether the PRB bundling size is wideband.
