摘要

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier scheduling. A base station may transmit downlink control information (DCI) messages via physical downlink control channel (PDCCH), to the UE to schedule the multiple PDSCH over multiple component carriers. The UE may monitor for the multiple PDSCH over the multiple component carriers, respectively. The UE may identify resource allocations to use for HARQ feedback transmissions associated with the multiple PDSCH, based on the DCI messages received. The DCI may include a number of control fields that the UE may use to determine resource allocations to use for the HARQ feedback transmissions. The UE may thus improve coverage for wireless communications by supporting HARQ feedback for multiple PDSCH scheduled via cross component carrier.
