無線通信システムのリモートノードによるランダムアクセスチャネルを介して信号を送信するための方法及びリモートノード装置

摘要

PURPOSE: A random access channel transmission method in a wireless communication system are provided to selectively perform a random channel transmission by considering channel state of reversed direction in a remote node of the wireless communication system. CONSTITUTION: A remote node measures power of a forward signal of a host node if a forward signal is received(301,303). The remote node checks a reference value for determining transmission of a random access channel(305). The remote node compares the power of the measured forward signal and the checked reference value(307). If the power of a forward signal is bigger than the reference value, the remote node transmits a signal through a reverse RACH(Random Access Channel)(309).
