Title:
CHANNEL STATE INFORMATION REPORTING WITH BASIS EXPANSION FOR ADVANCED WIRELESS COMMUNICATIONS SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2016/039565
Kind Code:
A1
Abstract:
Scalable channel state information feedback for FD-MIMO involves quantizing the downlink channel according to a finite set of basis vectors to reduce the number of coefficients quantized and reported from a user equipment to a base station. The procedure includes measurement at the base station of angle of arrival spread for uplink signal reception from the user equipment and signaling that spread to the user equipment. The user equipment then quantizes the MIMO channel according to a sub-scheme configured based upon the signaled spread and reports (feeds back) the quantized channel to the base station.
