Title:
METHOD AND APPARATUS FOR CONTROLLING UPLINK DATA TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING DUAL CONNECTIVITY
Document Type and Number:
WIPO Patent Application WO/2014/163435
Kind Code:
A1
Abstract:
The present invention relates to a method for controlling uplink data transmission in a wireless communication system supporting a dual connectivity, and an apparatus for the same. The present invention comprises the steps of: receiving, from a macro base station or a small base station, base station identification information required for the uplink data transmission in the dual connectivity environment, through an RRC signaling; performing uplink scheduling for each base station, on the basis of the base station identification information; and separately transmitting uplink data for the macro base station to the macro base station and uplink data for the small base station to the small base station, among uplink data uplink-scheduled for each base station .
