Title:
INTEGRATED CIRCUIT FOR RADIO COMMUNICATION, RADIO COMMUNICATION TERMINAL, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2017034561
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform scheduling in consideration of channel aging while keeping performance of receivers as a whole and the fairness of the individual receivers.SOLUTION: An integrated circuit for radio communication comprises a control unit 101 composed of a baseband integrated circuit that obtains a first parameter becoming a larger value as first communication quality with each of a plurality of radio communication terminals 1-4 is lower, obtains a second parameter becoming a larger value as second communication quality with each of the plurality of radio communication terminals is higher, increases a first weight for the first parameter and reduces a second weight for the second parameter according to the elapse of time, calculates an index value to select the plurality of radio communication terminals by using the first and second parameters and the first and second weights regarding each of the plurality of radio communication terminals; selects at least two radio communication terminals on the basis of the index value, and performs downlink multiuser MIMO transmission to the selected radio communication terminals.SELECTED DRAWING: Figure 1
