APPARATUS AND METHOD FOR SUPPORTING FREQUENCY REARRANGEMENT IN WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for supporting frequency relocation in a wireless communication system.

SOLUTION: A base station device includes: a center frequency setting unit, a local oscillator, a baseband processor, and a radio frequency (RF) processor. In the event of a frequency band change, the center frequency setting unit sets a center frequency of a use frequency channel so as to have an offset value just for a setting value with respect to a center frequency before the frequency band change. The local oscillator generates a local oscillation (LO) frequency signal according to the center frequency set by the center frequency setting unit. The baseband processor generates a downlink baseband signal. The RF processor uses the LO frequency signal to convert the downlink baseband signal generated by the baseband processor into a high frequency (RF) band signal and transmits the signal.
