Abstract

The embodiment of the invention relates to the field of communication, and discloses a beamforming method, a base station and a computer readable storage medium. The beamforming method is applied to abase station, and comprises the following steps: under the condition of determining a resource block binding range, performing phase compensation on each acquired first transmission matrix within theresource block binding range; according to each second transmission matrix, and determining an initial weight corresponding to each second transmission matrix, wherein the second transmission matrixis a compensated first transmission matrix; taking any one second transmission matrix as a reference transmission matrix, and correcting the initial weights corresponding to the other second transmission matrixes, so that the first equivalent channel corresponding to the corrected initial weight is equal to the reference equivalent channel. According to the embodiment of the invention, when a plurality of weights are adopted for forming in the resource block binding range, the forming precision can be improved, the continuity of the equivalent channel of UE in the frequency domain can be ensured, the accuracy of channel estimation is improved, and the throughput rate of a cell is improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a beamforming method, a base station, and a computer-readable storage medium. Background technique [0002] Beamforming or precoding technology (Precoding) is one of the main technologies of LTE and 5G, which can effectively improve the receiving power of users and realize the space division multiplexing of multiple users. In the TDD transmission mode, usually a sounding reference signal (Sounding reference signal, "SRS" for short) is used to measure the transmission matrix of the channel, and calculate the corresponding weighting value. The granularity of weight calculation is in units of resource blocks (Resource Block, referred to as "RB"). Between consecutive RBs, due to different RBs, the weights calculated by the SRS method are discontinuous in the frequency domain, causing the user equipment (UserEquipment , referred to as "UE") equivalent channel ...

Problems solved by technology

[0004] The inventors have found that at least the following problems exist in the prior art: within the scope of PRB bundling, the beamforming method using the same shaping weight value changes rapidly in channel frequency selection or multiple UEs are space-division multiplexed. , 2RB or larger RB forming granularity will make the forming weights inaccurate, resulting in inaccurate forming and thus degraded forming performance. In the case of multiple UE space division multiplexing, inaccurate forming will also cause UE Mutual interference among them is aggravated, which affects the throughput rate of the communication cell

In addition, within the range of PRB bundling, different RBs use different shaping weights. Although it can improve the shaping accuracy, it will cause the equivalent channel of the UE to be discontinuous within the range of PRB bundling, which will affect the estimation of UE downlink reception. In turn, the traffic is reduced and the throughput of the cell is reduced
