METHODS AND APPARATUS FOR SUPPORTING GROUP COMMUNICATIONS WITH DATA RE-TRANSMISSION SUPPORT

摘要

Methods and apparatus related to group communications in a wireless communications system, e.g., a peer to peer wireless communications system, are described. Methods and apparatus directed to closed groups, e.g., where the number of group members are fixed at a given time and known to one or more members of the group, are described. Various embodiments are well suited to decentralized peer to peer wireless networks including a plurality of individual traffic resources, e.g., traffic slots and/or traffic segments, which may be independently scheduled in a decentralized manner. Some features and/or aspects are directed to the use of individual group member acknowledgement signaling in response to a transmitted group traffic data signal. By monitoring for anticipated individual group member acknowledgment signals and identifying members which have not signaled a positive acknowledgment, re-transmission can be directed and/or tailored to a subset of the group.
