Resource allocation control method and device in mobile radio communications system
First Claim
1. A method of controlling resource allocation in a resource block including control resources used for a plurality of types of control signals and reference resources used for reference signals, to radio communications between a plurality of radio stations, comprising:
- measuring propagation channel quality between a first radio station and a second radio station at one or both of the first and second radio stations;
determining resource apportionment among the plurality of types of control signals and reference signals based on the propagation channel quality; and
notifying the other one of the first and second radio stations of the resource apportionment;
determining resource apportionment among the plurality of types of control signals and reference signals by determining a ratio between the plurality of types of control signals and reference signals, wherein the plurality of types of control signals includes channel quality information, which indicates the propagation channel quality; and
increasing the ratio of resource allocated to the channel quality information within the control resources as the propagation channel quality becomes better.

Abstract
For radio communications between a base station and a mobile station, resource allocation within a resource block including control resources used for control signals (CQI, ACK/NACK) and reference resources used for a reference signal is performed. The base station measures the quality of a channel between the mobile station and the base station itself. Based on the measured channel quality, the base station sets a ratio between resources for the control signals CQI and ACK/NACK in the control resources, and notifies the mobile station of the set resource ratio.
