Abstract:
A frequency deviation is to be estimated in a wireless communication system in which a control data transmission channel and a user data transmission channel are allocated to different frequency bands. An estimation result using a reference signal for modulation in the user data control channel and an estimation result using a reference signal for estimating channel quality may be combined, according to an estimation result using a reference signal for modulation in the control data transmission channel, in order to modify the allocation period of the reference signal for estimating channel quality depending on the estimation result.
