Abstract:
Various embodiments of the present disclosure provide a method for multicast communication. The method which may be performed by a terminal device comprises receiving a multicast traffic and/or a unicast traffic from a network node. The method further comprises transmitting feedback for the multicast traffic and/or the unicast traffic to the network node, according to a feedback codebook. The feedback codebook is based at least in part on a first feedback codebook type for the multicast traffic and/or a second feedback codebook type for the unicast traffic. According to various embodiments of the present disclosure, hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffics such as multicast and unicast traffics.
