1. A network coding device, comprising:
a transceiver;
a memory; and
a processor coupled to the transceiver and the memory, wherein the processor and the memory are configured to:
receive a first sidelink transmission transmitted from a transmitting wireless communication device to a receiving wireless communication device via the transceiver, the first sidelink transmission comprising a first packet and a first network coding request flag requesting the network coding device perform one or more retransmissions of the first packet;
receive feedback information for the first packet from the receiving wireless communication device at a first time via the transceiver;
transmit a first accept request message to the transmitting wireless communication device at a second time different than the first time via the transceiver, the first accept request message indicating whether the network coding device accepts performing the one or more retransmissions of the first packet; and
delay transmission of the first accept request message by a number of slots corresponding to a difference between the first time and the second time.
