METHOD AND APPARATUS FOR MULTICAST COMMUNICATION: abstract simplified (18012678)

• This abstract for appeared for patent application number 18012678 Titled 'METHOD AND APPARATUS FOR MULTICAST COMMUNICATION'

Simplified Explanation

The present disclosure describes a method for multicast communication. In this method, a terminal device receives both multicast and unicast traffic from a network node. The terminal device then sends feedback to the network node based on a feedback codebook. The feedback codebook is determined by two types of codebooks: one for multicast traffic and another for unicast traffic. This method allows for efficient and flexible implementation of hybrid automatic repeat request feedback for different types of traffic, such as multicast and unicast.

Original Abstract Submitted

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.
