Abstract:
Certain aspects of the present disclosure provide techniques for transmitting downlink control information (DCI) to schedule retransmissions of semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that were not successfully received. A method that may be performed by a user equipment (UE) includes receiving a downlink control information (DCI) that schedules retransmission of at least two semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that have hybrid automatic retransmission request (HARD) identifier (IDs); and receiving the retransmissions of the at least two PDSCHs.
