APPARATUS AND METHOD FOR COOPERATIVE RELAYING BASED ON BEAMFORMING IN A MOBILE COMMUNICATION SYSTEM

摘要

Cooperation relay method in the present invention and as movable signal relay method in a mobile communication system.Based on the device of Wave beam forming based on forming beam by repeater in a communication system the following steps are included:: check whether decoding error, it is by decoding one from transmitter signal, if decoding error has occurred and that, and acquisition beam forming weighting corresponding with decoding error information, wherein step applying electronic beam forms add weight to the signal from a transmitter receipt, method including being weighted for beam forming, its sending application signal, improve the decoding performance of terminal, unnecessary retransmission is reduced between base station and repeater, a kind of high transmission efficiency can be provided to the terminal being present in weak cell edge by receiving power from a signal of base station
