A METHOD OF TRANSMITTING SIGNAL IN A DISTRIBUTED ANTENNA SYSTEM

摘要

PURPOSE: A signal transmission method at a distributed antenna system is provided to configuring a code book for DAS which can variously operation according to a signaling by using an existing code book. CONSTITUTION: A base station determines DAS control information about a DAS(Distributed Antenna System) precoding matrix(S101). The base station transmits the determined DAS control information to a terminal(S102). According to the DAS control information, the base station selects an arbitrary precoding matrix from a preset code book for DAS.
