Title:
UPLINK DETECTION SIGNALS TRIGGERING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/084593
Kind Code:
A1
Abstract:
The embodiment of the present invention provides a uplink detection signals triggering method, device and system to at least solve the problem of large signaling overhead in the existing non-periodic SRS transmission and the problem of inflexible configuration in periodic SRS transmission. The method comprises: a base station transmits downlink control information (DCI) through a physical downlink control channel, wherein the DCI comprises the sounding reference signal (SRS) control information corresponding respectively to each of the "a" number of UEs in the base station managed cell, and the number "a" is positive integer not less than 2. The present invention is applicable in the field of wireless communication.
