Abstract

The present invention provides a method and device for receiving an object. The method includes: determining the association relationship between the target object and the source object; wherein, the object includes a reference signal or a channel, and the association relationship includes a quasi-site QCL relationship or a reception beam relationship. Since the method and device can determine the association relationship between the target object and the source object, and the association relationship includes the QCL relationship or the receiving beam relationship, it is possible to determine the receiving parameters of the target object, and then receive the target object, improving communication effectiveness .

Description

technical field [0001] The present invention relates to the technical field of communication, and more particularly relates to an object receiving 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] When transmitting a channel or reference ...
