DAI SCHEME FOR JOINT ACK/NACK FEEDBACK IN MULTI-TRP/PANEL TRANSMISSION

摘要

In accordance with some embodiments, an apparatus comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to configure a plurality of physical downlink control channels (PDCCHs) associated with a plurality of transmission receive points (TRPs), wherein each TRP corresponds with each PDCCH, and wherein each PDCCH comprises at least one downlink control information (DCI) field comprising at least one downlink assignment index (DAI). The apparatus further transmits at least one PDCCH associated with the at least one DAI according to at least one local DAI counting scheme and/or at least one global DAI counting scheme.
