Document Type and Number:
Japanese Patent JP6344489
Kind Code:
B2
Abstract:
A method and system for data communication in a Multiple-Input and Multiple-Output (MIMO) system is provided. The method includes receiving, from a first UE, first channel information relating to a first subset of a plurality of antennae of the MIMO system and second channel information relating to a second subset of a plurality of antennae. The method further includes generating first and second sub-precoders according to the first and second channel information, respectively. A precoder is then generated according at least in part to the first sub-precoder and the second sub-precoder, and data is transmitted to the first UE using the precoder.
