Abstract

The embodiment of the invention provides a CSI-RS (Channel State Information-Reference Signal) measurement method and device. The method is applied to access network equipment, and comprises the following steps: determining a target orientation group corresponding to a resource indication CSI-RS of a target channel state information reference signal to be triggered; determining a target terminal of the target azimuth group; wherein the target azimuth group corresponds to a target coverage range, and the target terminal is located in the target coverage range; and triggering the target terminal to measure the target CSI-RS. According to the embodiment of the invention, the problem that the MIMO performance is limited due to the limitation of the terminal capability in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a CSI-RS measurement method and device. Background technique [0002] In a Multiple Input Multiple Output (MIMO) system, codebook shaping is a commonly used shaping technology. In the New Radio (NR) protocol, many enhancements have been made to MIMO codebook (Codebook) design. However, due to the limitation of the processing capability of the terminal, the codebook methods already supported in many protocols cannot be used. Since the number of users in a cell can reach the order of hundreds or even thousands, although the Channel State Information-Reference Signals (CSI-RS) defined by the protocol is configured as a user-level parameter, if each The user allocates a set of 4-port CSI-RS resources, which is unbearable for the base station. Therefore, in the prior art, the codebook shaping scheme is usually implemented based on cell-level CSI-RS. [00...
