Hierarchical point-to-multipoint group communications between multiple active communication groups

摘要

A method and apparatus for facilitating group communications across multiple groups of wireless communication devices is described herein. A first wireless communication device is joined to a first group of wireless communication devices, and a second wireless communication device is joined to the first group and to a second group of wireless communication devices. When the first wireless communication device sets a retransmit indicator in a group message transmitted to the second wireless communication device, the second wireless communication device automatically retransmits the received group message to other wireless communication devices in the second group.
