Document Type and Number:
WIPO Patent Application WO/2019/134674
Kind Code:
A1
Abstract:
Provided by the present disclosure are a method for generating a precoding matrix and a device for generating a precoding matrix, the method comprising: selecting a predetermined number of transmission antenna ports from among a plurality of transmission antenna ports of a transmitting terminal, and forming transmission antenna port subsets; calculating a first multi-user multiple-input multiple-output preprocessing matrix that is used on the transmission antenna port subset of a first resource by a user; obtaining a second multi-user multiple-input multiple-output preprocessing matrix used on the transmission antenna port subset of a second resource by the user according to the first multi-user multiple-input multiple-output preprocessing matrix; and obtaining a precoding matrix used on the plurality of transmission antenna ports in a hybrid transmission mode by the user according to the first multi-user multiple-input multiple-output preprocessing matrix and the second multi-user multiple-input multiple-output preprocessing matrix.
