Abstract

The invention provides a channel and interference measurement method and device. The method comprises the following steps: receiving a first group of reference signal resources; and measuring a channel and interference corresponding to at least one first reference signal resource in the first group of reference signal resources. The channel and the interference corresponding to the first referencesignal resource are measured based on the quasi-common-site QCL information of the first reference signal resource. According to the method and the device, a measurement result capable of better reflecting the signal quality of a beam corresponding to the first reference signal resource can be obtained, so that the network device selects the ideal beam for sending the signal or the channel to theUE, the throughput rate is improved, and the block error rate is reduced.

Description

technical field [0001] This specification relates to the field of communication technologies, and more specifically relates to a channel and interference measurement 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 by beamforming is different, and parameter measurement is required, and an appropriate beam is selected for signal or channel transmission according to the measurement results. [0003] At present, when perfo...
