COMMUNICATION CONTROL METHOD, USER TERMINAL, AND BASE STATION |
| 摘要 |
A communication control method is applied to a mobile communication system including a base station that transmits a downlink signal through a plurality of antenna ports, and a user terminal that feeds back precoder matrix information to the base station, the downlink signal being precoded by using a precoder matrix, the precoder matrix information being indicating a precoder matrix preferably used in a downlink. The communication control method comprises: a step of feeding back, by the user terminal, correction value information for correcting the precoder matrix information to the base station when the precoder matrix information is fed back or after the precoder matrix information is fed back. |

1. A communication control method, which is applied to a mobile communication system including a base station that transmits a downlink signal through a plurality of antenna ports, and a user terminal that feeds back precoder matrix information to the base station, the downlink signal being precoded by using a precoder matrix, the precoder matrix information being indicating a precoder matrix preferably used in a downlink, the communication control method comprising:
a step A of feeding back, by the user terminal, correction value information for correcting the precoder matrix information to the base station when the precoder matrix information is fed back or after the precoder matrix information is fed back. |
