TRANSMISSION IN A RELAY NODE-BASED WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A transmission method in a wireless communication system based on a relay node is provided to reduce a latency which is related to DL transmission. CONSTITUTION: A received DL signal is demodulated for forming a preprocessed DL signal(520). A CQM(Channel Quality Measurement) value of the preprocessed signal is generated(525). The CQM value is determined to exceed a first threshold value(530). The preprocessed DL signal is demodulated for forming a processed signal(550). The processed DL signal is transmitted to a wireless device by cooperating with the first node(560).
