The relay station and relay transmission channel setting method in a mobile communication system

摘要

Relay station can reduce the control information necessary for assignment of relay transmission channel in a mobile communication system. The relay station (100), a demodulator (103) and a decoding unit (104), and demodulates and decodes the channel allocation information from the base station and the signal from the mobile station, extracting section (105), decoder ( and outputs (107) coder extracts the signal from the mobile station from the signal received from 104), and outputs the channel setting unit (106) by extracting channel allocation information from the base station, the channel setting unit (106), based on the channel allocation results shown in the channel assignment information, and sets the relay transmission channel according to a channel allocation scheme with the base station share the (100) RS encoding unit (107 The modulation unit (108), encodes and modulates again the signal from the mobile station, the channel allocation unit (109) assigns any of the relay transmission channel and the modulated signal) and.
