Title:
PRECODING MATRIX SET DETERMINATION METHOD AND TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/033868
Kind Code:
A1
Abstract:
Provided in the present application is a method for determining a precoding matrix set, which can avoid the situation that many precoding matrices in the precoding matrix set cannot be used, thereby improving system performance. The method comprises: a terminal device receives indication information; determining, by the terminal device, a second precoding matrix set from a first precoding matrix set of rank R according to the indication information, wherein each precoding matrix W in the first precoding matrix set satisfies W=W 1×W 2. the second precoding matrix set is a true subset of the first precoding matrix set, and the second precoding matrix set does not comprise an precoding matrix W in the first precoding matrix set that satisfies the following conditions : W＝W 1×W 2.
