Problems solved by technology

[0004] Since multiple control channel resource sets overlap on time-frequency resources, and the initial values ​​of different reference signal sequences are different, the resource size of the overlapping part does not affect the configuration of the reference sequence, resulting in different reference signal sequences mapped to the resource overlapping part, which cannot Realize the code division orthogonality of multiple reference signals in the resource overlapping area, which limits the performance of MU-MIMO transmission

Abstract

The invention relates to the field of mobile communication, in particular to a technology for acquiring a reference signal in a wireless communication system. In the method for acquiring the referencesignal, terminal equipment acquires offset position information, the terminal equipment acquires a first sequence according to the offset position information, and the terminal equipment demodulatesa control channel signal carried in a control channel resource set by using the first sequence to acquire downlink control information. Therefore, the MU-MIMO transmission performance is improved.

Description

Technical field [0001] The present application relates to the field of mobile communications, and more particularly to a technique of acquiring reference signals in a wireless communication system. Background technique [0002] In Long Term Evolution, LTE) network, the base station is typically a part of the area to which the system bandwidth is allocated to a particular terminal device. That is, within a specific time, a specific frequency regional resource is assigned to the terminal device. At this time, if the base station gives the quality of the quality of the particular frequency region resources to the terminal device, the service quality of the terminal device is more secure. In this process, the reference signal can provide a reference for the base station resource scheduling. [0003] At the same time, the reference point of the plurality of broadcast channels is simultaneously present at the same time. The generation method of the first sequence corresponding to the r...
