Patent ID: 8498270

Claim:
A wireless communication system, comprising: a mobile station comprising: a wireless channel quality measuring unit configured to measure wireless channel quality, a wireless channel quality determining unit configured to determine whether to report the wireless channel quality to a base station based on a threshold, a transmission unit configured to transmit the wireless channel quality to the base station based on the determination result of the wireless channel quality determining unit, and a normalization unit configured to normalize the wireless channel quality based on a mean value and variance of previous measurements of the wireless signal quality, wherein the wireless channel quality determining unit is configured to determine to report the wireless channel quality to the base station if the normalized wireless channel quality is greater than the threshold; and a base station comprising: a traffic measuring unit configured to measure the amount of traffic, a correction value calculation unit configured to calculate at least one of the threshold used by the mobile station to determine whether to report the wireless channel quality and a correction value for the threshold based on the amount of traffic, and a transmission unit configured to send at least one of the threshold and the correction value calculated by the correction value calculation unit to the mobile station, wherein the traffic measuring unit is configured to measure the amount of traffic based on total transmission power and the amount of data in a transmit buffer.
