摘要

The method, in a node, for a cellular communication system, retransmission of its first wireless signals to a plurality of mobile stations to a base station and a second wireless signals from the base station to the plurality of mobile stations, a device for a estau00e7u00e3 The retransmission in a wireless communication network.To relay the first wireless signals from mobile stations to a base station and a second wireless signal from the base station to the mobile stations and apparatus and method for a mobile station in a wireless communication network.It is described the best relay amplify and forward type in a communication network includes a network model of multiple mobile stations of single antenna, a retransmission multiantenas station and a base station multiantenas.Bidirectional communication with the greatest efficiency of transmission is enabled by appropriate processing at the switching station without the shortcomings of the current techniques of retransmission.The matrices of linear processing for transmission and reception are disclosed, and shows that the number of antennas at the switching station and the base station may be substantially the same without reducing the capacity of the network.Corresponding closely the performance for low and high signal to noise of roots of the current techniques that require the switching station has two times more antennas to the base station.
