Abstract

This specification provides a method and device for reference signal measurement and reference signal resource configuration. The reference signal measurement method includes: determining a first group of reference signal resources and a second group of reference signal resources, and the first group of reference signal resources is used for measuring channels , the second group of reference signal resources is used to measure interference; the reference signal carried by at least one second reference signal resource in the second group of reference signal resources is measured, and the corresponding first reference signal resource in the first group of reference signal resources is obtained. interference, wherein, when measuring the reference signal carried by the second reference signal resource, if the second reference signal resource overlaps with the third reference signal resource in the first set of reference signal resources, measure the reference signal carried by the second reference signal resource The position of the reference signal is a resource position corresponding to the third reference signal resource. The method and equipment provided in this manual can improve the accuracy of inter-beam interference measurement during beam measurement.

Description

technical field [0001] This specification relates to the field of communication technologies, and more specifically relates to a reference signal measurement and reference signal resource configuration method and device. Background technique [0002] In order to support the access of a larger number of users, multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) technology with a larger scale and more antenna ports is introduced into the mobile communication system, such as a large-scale MIMO (Massive MIMO) technology. Beamforming is one of the key technologies for realizing multi-user MIMO (Multi-User MIMO, MU-MIMO) in Massive MIMO. It can generate directional beams by adjusting the weighting coefficient of each array element in the antenna array. The quality of different beams obtained through beamforming is different, which needs to be measured, and an appropriate beam is selected for signal or channel transmission according to the measurement results. ...
