LOCAL SELECTION OF RETRANSMITTING DEVICE IN COOPERATIVE CLUSTER TO ENHANCE CELLULAR MULTICAST

摘要

A method for local selection of a retransmitting user equipment within a cluster comprises: selecting first retransmission indication information according to a first pre-defined criterion, in response to receipt of non-acknowledgement information from at least one non-acknowledgement user equipment at which a data packet from a network node is decoded incorrectly; performing a local selection of a retransmitting user equipment within a cluster based at least in part on the first retransmission indication least one non-acknowledgement user equipment, and at least one acknowledgement user equipment at which the data packet is decoded correctly; and determining whether or not to retransmit the data packet to the at least one non-acknowledgement user equipment, based at least in part on the local selection of the retransmitting user equipment.
