WIRELESS COMMUNICATION METHOD, BASE STATION, AND USER TERMINAL

摘要

Disclosed is a base station in a wireless communication system in which each user terminal uses a frequency in a different data transmission band assigned by the base station to transmit a data signal to the base station and time-multiplexes a pilot signal with the data signal to transmit the pilot signal to the base station. A resource management unit in the base station offsets part of frequency band of the entire data transmission band on a per each user terminal basis and determines a pilot transmission band of a user terminal so that the pilot transmission band of the user terminal covers the data transmission band of the user terminal. The resource management unit then instructs the user terminal to transmit the pilot signal using a frequency in the determined pilot transmission band.
