Patent ID: 8134979

Claim:
A method of implementing wireless traffic backhaul between a first base station and a second base station in a wireless communication network, the method comprising: a) forming an uplink backhaul channel and a downlink backhaul channel between said first base station and said second base station by using timeslots of base stations' own; and b) implementing uplink and downlink traffic backhaul between said first base station and said second base station by using said uplink backhaul channel and said downlink backhaul channel; wherein the first and second base stations use the same frame length, each frame comprising a downlink and a consecutive uplink part; wherein a time offset is determined in accordance with a radio resource scheduling algorithm and a radio resource reservation algorithm; wherein the time offset is used to offset the frame start time of the second base station in relation to the frame start time of the first base station, so as to form an uplink backhaul window and a downlink backhaul window between the first base station and the second base station; wherein the duration of the downlink backhaul window and the uplink backhaul window is equal to the time offset; wherein the first base station is a master of the second base station and the second base station is a slave of the first base station; wherein backhaul traffic is between the master base station and slave base station, and any local user access traffic is between either the master base station or slave base station and a mobile station.
