Abstract

Provided in embodiments of the present invention are a channel state information reporting method, terminal and network side device, the method comprising: determining at least one target mapping modein a first mapping mode, with the first mapping mode comprising at least two mapping modes, the mapping modes being used to represent a mapping relationship between a codeword and a transport layer;calculating channel state information CSI according to the target mapping mode; and reporting the CSI to network side equipment. A plurality of mapping modes are defined, and the target mapping mode is determined in the plurality of mapping modes to calculate and report the CSI. Therefore, in different transmission processes, the different mapping modes can be adopted to calculate and report the CSI, so that the flexibility of CSI reporting can be improved to support coordinated multi-point transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for reporting channel state information, a terminal and a network side device. Background technique [0002] The feedback of channel state information (Channel State Information, CSI) determines the performance of multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) transmission, and therefore plays a pivotal role in the entire MIMO design. In the Long Term Evolution (LTE) system, multiple different feedback types are defined in different standardized releases (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 CS...
