Title:
無線通信システム
Document Type and Number:
Japanese Patent JP4801740
Kind Code:
B2
Abstract:
Each of terminals, when receiving a signal from a base station, calculates and notifies a CQI of the received signal to the base station. The base station uses the notified CQI values to calculate a CQI threshold value, and notifies it to each terminal. Then, each of the terminals, when determining/calculating a CQI value of a downlink channel, compares it with the notified CQI threshold value. If the calculated CQI value is smaller than the CQI threshold value, then the terminal halts the notification of CQI value to the base station. The base station receives reports of CQI values only from terminals at which the CQI values are greater than the CQI threshold value, and implements a scheduling only for these terminals so as to have communication only with these terminals.
