Abstract

The present invention provides a method and device for measuring signal quality parameters, the method comprising: receiving a first reference signal resource set for measuring multiple signal quality parameters; measuring the target signal quality parameters based on at least one first reference signal resource Signal parameters, measuring a first interference parameter among the target signal quality parameters based on at least one second reference signal resource; the target signal quality parameter is any one of multiple signal quality parameters, and the first reference signal resource is a first reference signal The reference signal resource corresponding to the target signal quality parameter in the resource set, the second reference signal resource is a reference signal resource other than the first reference signal resource in the first reference signal resource set. The method and device can obtain measurement results that can better reflect the channel quality of beams corresponding to multiple signal quality parameters, and the network device can determine the ideal beam for sending signals or channels to terminal devices, thereby improving throughput and reducing errors. block rate.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly to a method and device for measuring signal quality parameters. 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 by beamforming is different, and signal quality parameters need to be measured, and an appropriate beam is selected for signal or channel transmission based on the measurement results. [0003] At present, when p...
