一种信道状态信息的测量与反馈方法、用户设备及基站技术

本发明专利技术涉及通信领域，具体涉及一种信道状态信息的测量与反馈方法。该方法包括：UE接收基站配置的第一信道状态信息报告类型以及基站下发的K个信道状态信息参考信号CSI‑RS资源，K为大于等于1的整数；UE根据信道状态信息报告类型在传输K个CSI‑RS资源的宽带的S个子带上确定出一个秩指示RI和/或一个波束赋形指示BI，S为大于等于1的整数；UE在S个子带上计算得到信道质量指示CQIUE在物理上行控制信道PUCCH上通过报告上报RI、BI和CQI。本发明专利技术实施例由于在PUCCH反馈模式中重新设计了反馈方式，使得BI能够顺利上报，从而能够适应Beamformed CSI‑RS机制。

Measurement and feedback method of channel state information, user equipment and base station

The invention relates to the field of communication, in particular to a measurement and feedback method for channel state information. The method includes: the first channel state information report type of UE receiving base station configuration and the K channel state information reference signal CSI RS resource, K is an integer greater than 1; UE determines a rank indicator RI and / or the channel state information report type on the S subband of the K CSI RS resource. Or a beamforming indication BI, S is an integer greater than equal to 1; UE is calculated on the S subband to indicate the channel quality indication CQIUE on the physical uplink control channel PUCCH to report RI, BI and CQI on the report. The embodiment of the invention has redesigned the feedback mode in the PUCCH feedback mode so that the BI can be successfully reported and can be adapted to the Beamformed CSI RS mechanism.
