1. A communication feedback method, applicable to a multicast transmitter, comprising:
determining a target subset from a set of multicast receiving devices, the set of multicast receiving devices comprising a plurality of multicast receivers that receive multicast communication, the target subset comprising at least one target multicast receiver in the plurality of multicast receivers; and
transmitting a first control signaling, wherein the first control signaling is for instructing the target multicast receiver in the target subset to employ a first feedback mode to give feedback, the first feedback mode for feeding an acknowledgement character ACK back when communication data transmitted by the multicast transmitter is received correctly and for feeding a negative acknowledgement character NACK back when communication data transmitted by the multicast transmitter is not received correctly;
wherein the first control signaling is further for instructing other multicast receivers outside the target subset to employ a second feedback mode to give feedback, and the second feedback mode is for not feeding back when communication data transmitted by the multicast transmitter is received correctly and for feeding the NACK back when communication data transmitted by the multicast transmitter is not received correctly.
