Title:
METHOD AND DEVICE FOR PERFORMING NIB COMP TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/016583
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and device for performing or supporting NIB coordinated multi-point (CoMP) transmission in a wireless communication system. The method and device for performing NIB CoMP transmission in the wireless communication system according to an embodiment of the present invention include: transmitting a first-type signal including one or more first CoMP hypothesis sets and one or more first benefit metrics from a first network node to a second network node; and receiving, by the first network node, a second-type signal including one or more second CoMP hypothesis sets and one or more second benefit metrics from the second network node. One or more of the first-type signals or the second-type signals may further include one or more sets of channel state information (CSI) on one or more pieces of user equipment (UE) and the one or more sets of the CSI may include CSI generated for each CSI-process index. The CSI-process index may be defined as a value uniquely identified in the wireless communication network.
