Abstract
Official abstract text for this publication.
Provided is a differential precoding method for reducing inter-user interference and increasing the sum rate. The differential precoding method comprises initializing a precoding matrix with a first (Precoding Matrix Indicator (PMI) for a channel between a mobile station and a base station; and updating the precoding matrix with a second PMI for the channel and side information for adaptively updating the precoding matrix according to a change speed of a state of the channel, wherein the side information has a quantized scalar value.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for differential precoding, the method comprising: initializing a precoding matrix with a first Precoding Matrix Indicator (PMI) for a channel between a mobile station and a base station; and updating the precoding matrix with a second PMI for the channel and side information for adaptively updating the precoding matrix according to a change speed of a state of the channel, wherein the side information has a quantized scalar value, and w…
