Title:
UPLINK MU-MIMO TRANSMISSION METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/188147
Kind Code:
A1
Abstract:
Provided are an uplink multiple user-multiple input and multiple output (MU-MIMO) transmission method and device. The method comprises: determining a first terminal and a second terminal in MU-MIMO paired terminals; acquiring a current time delay difference between the paired terminals; calculating, according to a preset multipath channel time delay and the current time delay difference, a first fixed lead time value of the first terminal and a second fixed lead time value of the second terminal, and enabling a difference between the first fixed lead time value and the second fixed lead time value to be equal to the multipath channel time delay; and transmitting the first fixed lead time value to the first terminal, and transmitting the second fixed lead time value to the second terminal, such that the first terminal and the second terminal can respectively transmit uplink data according to the first fixed lead time value and the second fixed lead time value. Also disclosed is a computer storage medium.
