Embodiment Construction
[0053] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.
[0054] The application scenario of the solution of the present invention is firstly explained below.
[0055]When calculating the downlink beamforming weight vector, there are mainly two implementation methods: one is to use the sounding reference symbol SRS to calculate the downlink beamforming weight vector, and the other is to use the precoding matrix to indicate the PMI to calculate the downlink beamforming weight vector. Wherein, the method of calculating the weight vector by using the PMI is applicable to both a TDD (Time Division Duplex, time division duplex) system and an FDD (Frequency Division Duplex, frequency division duplex) system. The method of using SRS to calculate the weight vector is only app...
