Patent number: 9059753Abstract: The specification and drawings present a new method, apparatus and software related product for using non-codebook based CSI feedback (e.g., in LTE wireless systems) using selection by a UE of one or more of the plurality of logical antenna ports based on a predefined procedure (e.g., SNR or SINR measurement), but without selecting any codeword (precoder) by the UE. This allows not to involve any standardization of codebooks for precoding due to reliance on an alternative CSI feedback framework which does not rely on standardized codebooks. The exemplary embodiments described herein aim at development of 3GPP LTE Release-12.Type: GrantFiled: September 27, 2012Date of Patent: June 16, 2015Assignee: Nokia Solutions & Networks OyInventors: Weidong Yang, Timo Erkki Lunttila, Xiao Yi Wang
