WIRELESS COMMUNICATIONS NETWORK COMPRISING MULTI-HOP RELAY STATIONS

摘要

A method provides for conveying wireless communications in a radio network using OFDMA or multi-carrier technologies. The wireless network includes a first relay station and a subscriber station operative to communicate with that first relay station. The first relay station is operative to simultaneously transmit to or receive communications from at least two recipients along a shared frequency channel. The two recipients are wireless entities selected from among: the base station and a subscriber station; or another relay station and a subscriber station; or the base station and another relay station. The wireless communications network can further include a second relay station, which is operative to simultaneously transmit to or receive communications from at least two recipients selected from among: the first relay station and a subscriber stations, or a third relay station and a subscriber station, or the first relay station and a third relay station.

主权项

1. A method for conveying wireless communications in a wireless communications network comprising base stations, relay stations and subscriber stations, the method comprising:
during a first time partition of a frame, at a first base station (BS1), transmitting a first downlink (DL) segment carrying base station DL traffic for a first relay station (RS1), and transmitting a second DL segment carrying base station DL traffic for subscriber stations (SS1) served by the BS1; at the RS1, receiving a first uplink (UL) segment carrying subscriber station UL traffic from subscriber stations (SS2) served by the RS1; during a second time partition of the frame, at the BS1, receiving a second UL segment carrying subscriber station UL traffic from subscriber stations (SS1) served by the BS1 and a third UL segment carrying relay DL traffic from RS1; and at the RS1, transmitting a third DL segment including relay DL traffic for the SS2; wherein each segment is allocated a group of frequency sub-channels.
