Abstract

The embodiment of the invention discloses a channel information determination method, network equipment and terminal equipment, and aims to solve the problems of signaling overhead and time delay caused by updating, activating or indicating the channel information by using an MAC CE command in a multi-CC, multi-BWP or multi-TRP scene. The method comprises the following steps of: updating, activating or indicating parameter information of a first channel or a first reference signal (RS) by using a media access control (MAC) control element (CE) command; the parameter information of the first channel or the first reference signal RS is used for determining parameter information of a second channel or a second RS under a preset condition; wherein the parameter information comprises at least one of TCI (Transmission Configuration Indication) state information, spatial relationship information and PL RS (Path Loss Reference Signal). According to the technical scheme, the method for determining the parameter information of the second channel or the second RS under a plurality of different conditions (scenes) is perfected, and the signaling overhead and the time delay when the channel information is configured or indicated are reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for determining channel information, network equipment and terminal equipment. Background technique [0002] In the standard formulation process of the New Radio (NR) communication system by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), the operating frequency band supported by the system is increased to above 6GHz. The high frequency band has relatively abundant idle frequency resources, which can provide greater throughput for data transmission. The wavelength of the high-frequency signal is shorter than that of the low-frequency band. More antenna elements can be arranged on the same size panel, and the beamforming technology can be used to form a beam with stronger directivity and narrower lobes. [0003] The analog beamforming is transmitted over the full bandwidth, and each polarization element on the panel of each high-freque...
