Abstract

The present disclosure relates to a user equipment (UE), a network node, and communication methods for the UE and the network node, respectively. The UE includes: a transceiver that, during operation, receives, on a physical downlink control channel (PDCCH), downlink control information (DCI) for scheduling multiple transmissions or receptions between the UE and multiple transmission / reception points (TRPs) on multiple channels, the DCI including one or more indicators indicating one or more transmission parameters, respectively; and circuitry that, during operation, obtains multiple values ​​for each of the one or more transmission parameters based on the one or more indicators and a configuration. The transceiver, during operation, performs the multiple transmissions or receptions using a respective one of the multiple values ​​of the one or more transmission parameters for each of the multiple transmissions or receptions.
