Title:
直交周波数分割多重接続方式を用いる通信システムにおけるアップリンクパイロット信号送受信装置及び方法
Document Type and Number:
Japanese Patent JP4391526
Kind Code:
B2
Abstract:
An apparatus and method for transmitting a reference signal in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system in which a total frequency band is divided into a plurality of subcarrier bands. A time division multiplexer performs time division multiplexing such that the reference signal is transmitted for a first duration in a predetermined number of subcarrier bands from among the plurality of the subcarrier bands, and a signal other than the reference signal is transmitted for a second duration other than the first duration. A transmitter transmits the time-division multiplexed subcarrier band signals.
