Abstract

The invention discloses a channel state information reporting configuration method, a channel state information reporting method, network equipment and a terminal. The method at the network equipmentside comprises the following steps: configuring at least one reporting feedback setting and a channel state information reference signal (CSI-RS) measurement resource setting corresponding to each reporting feedback setting for a terminal, wherein each reporting feedback setting corresponds to at most three measurement resource settings. According to the scheme of the invention, the CSI reportingproblem of supporting dynamic panel / transmission point selection during multi-panel / transmission point transmission can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a channel state information reporting configuration, reporting method, network equipment and terminal. Background technique [0002] The feedback of Channel State Information (CSI) determines the performance of MIMO (Multiple-Input Multiple-Output) transmission, and therefore plays a pivotal role in the entire MIMO design. In the LTE system, a variety of different feedback types are defined in different standardization versions (Rel-8~Rel-14) to support CSI channel information feedback of different MIMO transmission schemes. This design leads to the dispersion and complexity of different transmission schemes and information feedback. In order to avoid introducing multiple feedback types / sub-feedback types in the 5G system, consider designing a unified CSI feedback framework. The system design decouples CSI measurement and CSI feedback methods, separates measureme...
