Document Type and Number:
WIPO Patent Application WO/2014/171700
Kind Code:
A1
Abstract:
The present invention provides methods for transmitting a sounding reference signal (SRS) in a wireless access system supporting a multiple connection mode, in which user equipment is connected to two or more small cells, and devices for supporting same. According to one embodiment of the present invention, the method for the user equipment transmitting the SRS in the wireless access system supporting the multiple connection mode, comprises the steps of: receiving, from a first small cell in the multiple connection mode, a control signal requesting an aperiodic SRS transmission; and confirming whether a first SRS resource region for the aperiodic SRS transmission to the first small cell and a second SRS resource region for a periodic SRS transmission to a second small cell in the multiple connection mode overlap, wherein the user equipment in the multiple connection mode maintains multiple connections with the two or more small cells, including the first small cell and the second small cell, and wherein the first small cell and the second small cell can be mutually connected through a non-ideal backhaul link.
