1. A network node, comprising:
radio front end circuitry; and
processor circuitry configured to:
generate a radio resource control (RRC) signal that includes a transmission/reception point (TRP) cluster size defining a size of a TRP cooperation cluster;
map a plurality of scheduled physical downlink shared channel (PDSCH) layers to TRPs in the TRP cooperation cluster based at least on a rank, the TRP cluster size, and indexes of the TRPs in the TRP cooperation cluster;
transmit, using the radio front end circuitry, the RRC signal to a user equipment (UE) to enable multi-TRP transmission; and
perform a PDSCH transmission in accordance with the mapping of the plurality of scheduled PDSCH layers to the TRPs.
