Title:
BASE STATION, MOBILE STATION, AND SUB-CARRIER MAPPING METHOD
Document Type and Number:
WIPO Patent Application WO/2009/025251
Kind Code:
A1
Abstract:
In a radio communication system, a subcarrier is effectively used in correspondence
with a change of a subcarrier communication environment by using line quality
information. According to line quality information reported from a mobile station,
a base station can recognize the state of the communication environment between
the base station and the mobile station. According to the recognized communication
environment state, transmission information associated with communication
control is selectively mapped to a particular subcarrier used for delivery.
