1. A method for wireless communications at a user equipment (UE), comprising:
receiving, in accordance with a first semi-persistent scheduling configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first radio network temporary identifier;
transmitting feedback information for the group-common transmission;
receiving a semi-persistent scheduling retransmission configuration indicating whether a group-common retransmission scheme or a unicast retransmission scheme is to be used; and
receiving a downlink control information message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel, wherein the downlink control information message schedules either the group-common retransmission or the unicast retransmission in accordance with the semi-persistent scheduling retransmission configuration, the group-common retransmission and the unicast retransmission being associated with a second radio network temporary identifier that is either the same as, or different than, the first radio network temporary identifier.
