ALGORITHM FOR GROUPING STATIONS FOR TRANSMISSION IN A MULTI-PHASE FRAME STRUCTURE TO SUPPORT MULTI-HOP WIRELESS BROADBAND ACCESS COMMUNICATIONS

摘要

A station grouping mechanism has been presented for a wireless device that collects Multi-hop Relay Base Station (MR-BS) and Relay Stations (RSs) into groups according to their locations in a tree topology and assigns them with a phase. Grouping or partitioning MR-BS and RSs and assigning a distinct phase to the group prevent the MR-BS and the RSs from transmitting and receiving at the same time.
