1. An apparatus comprising:
a processor to:
determine whether a current new data indicator in a current sidelink grant matches a last received new data indicator in a last received sidelink grant for a first hybrid automatic repeat request process;
in response to the current new data indicator matching the last received new data indicator, determine whether a first positive acknowledgement was transmitted by the apparatus in response to the last received sidelink grant; and
in response to determining that the first positive acknowledgement was transmitted, clear a physical sidelink control channel (PSCCH) duration and a physical sidelink shared channel (PSSCH) duration corresponding to retransmission of a medium access control (MAC) protocol data unit (PDU) from the current sidelink grant.
