Title:

SIGNAL TRANSMISSION METHOD OF WIRELESS COMMUNICATION SYSTEM, BASE STATION AND USER EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2017/124994

Kind Code:

A1

Abstract:

Embodiments of the invention provide a signal transmission method of a wireless communication system, the method comprising: selecting a phase correction value for a k-th layer of user data of the wireless communication system, performing, according to the phase correction value, a phase rotation on a reference signal in the k-th layer user data, so that a signal power of the reference signal, after performing inference mitigation thereon at a transmission end, does not exceed a predetermined power threshold, wherein, k is selected from 1 to M, and M is less than or equal to K, and K is the total number of layers of user data of the wireless communication system; and transmitting, through a wireless channel, the reference signal after the phase rotation.
