multi-hop relay system, the data transmission method , data transmission apparatus , and a communication system

摘要

The present invention relates to a method of transmitting data in a multi-hop relay system, the base station from the first terminal the base station and the information of the channel between the first terminal (H _{d, 1} ) the step of receiving, the base station is the H _{d, 1 interference removal using a} precoded generating a matrix, the method comprising: the base station transmits first data to a relay, and the repeater is transmitting the first data to the first terminal and the second base station using the pre-coding matrix to convert the interference cancellation 2 the data comprising the step of transmitting to the second terminal. ; the multi-hop relay system, according to the transmission data at the base station repeater is room to transfer data to other terminals in the present invention can effectively transmit data to the mobile station, due to the existing transmission system can be used for the release of waste resources efficiently, and improve the overall data transmission rate of the base station. ; multi-hop system, the pre-coding matrices
