Method and User Equipment for Feeding Back Channel State Information |
摘要 |
The present document provides a method for feeding back channel state information and a user equipment. The method includes: a user equipment determining a second parameter y of a feedback mode according to the number of Channel-State Information-reference signals (CSI-RS) ports configured by a high layer signaling or according to the number of CSI-RS ports and indication information indicating whether to feed back a pre-coding matrix indicator (PMI) and rank indicator (RI); the user equipment determining the feedback mode according to a transmission mode configured by the high layer signaling, a first parameter x of the feedback mode and the second parameter y of the feedback mode; and the user equipment feeding back the channel state information according to the determined feedback mode. The present document improves the system flexibility and performance and reduces the feedback overhead. |
