Abstract
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.
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.
This invention claims a wireless communication method and base station and user terminal. The base station for use in a wireless communication system in the wireless communication system each user terminal using a downlink radio resource assigned by the base station for the data transmission frequency band for transmitting data signal to the base station at the same time division multiplexing pilot frequency signal for a signal so as to transmit to the base station. Resource management part of the base station aiming at each user terminal sending a part of frequency band frequency band to apply bias to the total data determining a pilot frequency frequency band of the user terminal the user terminal sending system of measuring pilot frequency band covers the data of the frequency band sent by the user terminal indicating the user terminal to make the user terminal to use the determined pilot frequency transmission frequency band to transmit pilot signal.
