Title:
BASE STATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2004/091126
Kind Code:
A1
Abstract:
It is possible to use a frequency of a preferable propagation condition while reducing the other cell interference by hopping. A scheduler section (102) performs scheduling for deciding a user to whom data is transmitted, by using the CQI from each communication terminal device, selects a user signal to be transmitted in the next frame, and decides a sub-carrier block by which the transmission is performed. An MCS judgment section (103) selects a modulation method and a coding method from the CQI of the user signal selected. A sub-carrier block selection section (110) selects a sub-carrier block specified by the scheduler section (102) for each user signal. For each of the sub-carrier blocks, the hopping pattern is selected by FH-sequence selection sections (111-1 to 111-n). A sub-carrier mapping section (112) maps the user signal and the control data to the sub-carrier according to the hopping pattern selected.
