WIRELESS COMMUNICATION TERMINAL DEVICE, WIRELESS COMMUNICATION BASE DEVICE, AND METHOD FOR GENERATING CSI

摘要

The purpose of the present invention is to be able to simultaneously generate three or more sets of CSI within a predetermined time interval, without degrading the accuracy of the CSI, to achieve CoMP control for flexible switching of base stations. At predetermined intervals or at timing coincident with reception of trigger information, a generation unit uses a CSI-RS resource to measure a desired signal component and interference component, and generate CSI. A transmission unit transmits control information including the CSI. During a given interval (for example, during four subframes) following reception of trigger information, the generation unit does not measure the interference component, instead using the most recent previously measured interference component, to measure the channel quality.

主权项

1. A radio communication terminal apparatus comprising:
a generation section that generates CSI (Channel State Information) using a desired signal component and an interference component; and a transmitting section that transmits the CSI, wherein when receiving trigger information that requests a CSI report and generating the CSI, the generation section uses an interference component measured before receiving the trigger information.
