WIRELESS BASE STATION, USER TERMINAL, WIRELESS COMMUNICATION METHOD, AND WIRELESS COMMUNICATION SYSTEM |
摘要 |
The present invention is designed to prevent the decrease of throughput and also reduce the overhead of CSI feedback when CoMP transmission is applied. A radio base station is configured to be able to perform coordinated multiple-point transmission/reception with a user terminal, and includes a detection section configured to detect a retransmission control signal fed back from the user terminal, and a CQI updating section configured to update a CQI for coordinated multiple-point transmission/reception using received quality information in each cell, and the CQI updating section updates the CQI using a calculating formula that is defined with the received quality information in each cell and a variable which changes the value depending on the content of the retransmission control signal. |
