Title:
METHOD AND APPARATUS PROVIDING INTER-TRANSMISSION POINT PHASE RELATIONSHIP FEEDBACK FOR JOINT TRANSMISSION COMP
Document Type and Number:
WIPO Patent Application WO/2013/136298
Kind Code:
A3
Abstract:
Systems and techniques for joint transmission cooperative multi-point operation are described. A set of n channel state information reference signal resources is configured, which are to be measured by a user device. The set of n channel state information reference signal resources includes at least one channel state information reference signal resource that spans over at least two transmission points. Channel state information feedback corresponding to each channel state information reference signal resource is configured. Upon receiving channel state information from the user device, at least one precoder is selected for accomplishing a coherent joint cooperative multipoint based at least in part on inter-transmission point phase relationship information.
