Abstract

Embodiments of the present invention provide a capability information reporting method, a precoding matrix indication feedback method, and related equipment. The capability information reporting method includes: reporting capability information, where the capability information is used to indicate whether the terminal supports the first capability. The first capability mentioned above is: supporting the capability that the size of the PMI subband is smaller than the size of the CQI subband. The embodiment of the present invention can improve the performance of the terminal and the accuracy of PMI feedback, thereby improving communication performance.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a capability information reporting method, a precoding matrix indicator (Precoding Matrix Indicator, PMI) feedback method and related equipment. Background technique [0002] In a communication system, a terminal often needs to feed back channel state information (Channel State Information, CSI) to the network, where the CSI includes PMI. However, in practical applications, the PMI subband size (subband size) supported by the terminal may not match that understood by the network side, resulting in relatively poor performance of the terminal. Contents of the invention [0003] Embodiments of the present invention provide a capability information reporting method, a PMI feedback method and related equipment, so as to solve the problem of relatively poor terminal performance. [0004] In the first aspect, a method for reporting capability information provided...
