Abstract:
1. A channel quality measuring method for measuring channel quality for each of a plurality of mobile stations at a base station in a frequency band including a plurality of frequency blocks, comprising: determining whether or not a resource is allocated to a mobile station for a resource for an uplink data signal and/or a control signal; a) when said determining step determines that the resource is to be allocated for the uplink data signal and/or the control signal to a mobile station, the mobile station performs transmission of the uplink data signal and/or the control signal in any one of the plurality of frequency blocks, and the base station attempts to allocate a demodulation pilot resource to the mobile station; b) when said determining step determines that neither the resource for the uplink data signal nor the resource for the control signal is to be allocated to a mobile station, the mobile station waits for uplink data signal transmission scheduling, and when the frequency band includes any available block, the base station attempts to allocate a channel quality measurement-specific pilot resource specific to the mobile station; and c) measuring channel quality for each of the plurality of mobile stations using the demodulation pilot resource and/or the channel quality measurement-specific pilot resource.
