Title:
WIRELESS MOBILE TERMINAL AND FEEDBACK INFORMATION TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/049860
Kind Code:
A1
Abstract:
Provided are a wireless mobile terminal and a feedback information transmission method with which it is possible to balance the improvement in effect of base station coordinated transmission and reduction in the amount of returns. A wireless mobile terminal (100) is provided with: a channel estimation unit (140) for estimating channel information from a transmitted signal; Doppler spectrum calculation units (153) for calculating a Doppler spectrum expressing change in a propagation path from the estimated channel estimation value; selection units (154) for selecting a finite number of specific frequency components in which power has been concentrated from the calculated Doppler spectrum; and a terminal transmission unit (160) for returning the selected frequency components as base station coordinated transmission feedback information.
