Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0038] The present invention is designed for the uplink based on the cellular relay mobile communication system, and is used to improve the relay uplink transmission efficiency and the quality of the transmission signal. Its system structure consists of figure 1 As shown, there are N (N≥2) users MS in the system network i (The natural number subscript i is the user serial number, and its maximum value is N) communicates with the base station BS with the help of the relay node RS.
[0039] Since the method of the present invention has different operation modes at the user end, the relay node and the base station, its specific implementation process can be divided into three steps according to the operation objects at different locations. The transmission process ...
