Transmission method for broadcast/multicast feedback signaling

The invention discloses a transmission method for broadcast/multicast feedback signaling, which comprises an uplink resource allocation process, a feedback signal generating process and a feedback signal sending process. The uplink resource allocation process is that all the child nodes which probably feed back to the same parent node allocate the same time frequency resource so as to support that transmission of the feedback signaling. In the feedback signal sending process, each child node checks first whether the locally received broadcast/multicast data packet is right or not; if an erroris found and cannot be corrected, an NAK signaling is sent at a given time frequency position corresponding to the data packet in the uplink resource allocation process. The broadcast/multicast feedback signal transmission method provides a method for multiplexing a plurality of feedback signals at the same time frequency position to make the spending of the broadcast/multicast feedback signal independent of the number of
