Center frequency control method in wireless access system

摘要

The present invention relates to a method and an apparatus that supports a multi-carrier wireless access system for transmitting and receiving system information. The 1st embodiment of the present invention is a method for controlling a center frequency in a wireless access system comprising the steps of: receiving a control message including a 1st parameter which indicates a configuration of carrier groups and a 2nd parameter which indicates whether the center frequency is controlled from a base station; deriving the center frequency of carriers allocated to a mobile terminal by using the 1st parameter; and controlling the center frequency by using the 2nd parameter.

1. A method for adjusting a frequency by a mobile station in a wireless access system, the method comprising:
receiving, by the mobile station, a control message from a base station, the control message including:
a first parameter indicating a configuration of a carrier group,a second parameter indicating whether or not a center frequency has been adjusted, anda physical carrier index indicating an index of each physical carrier of the carrier group; obtaining, by the mobile station, a center frequency of a carrier allocated to a mobile station using the first parameter and the physical carrier index; and adjusting, by the mobile station, the center frequency of the carrier using the second parameter.
