Title:
TRANSMISSION DEVICE AND METHOD FOR CHANNEL STATE INFORMATION REFERENCE SIGNAL, AND COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/156770
Kind Code:
A1
Abstract:
A transmission device and method for a channel state information reference signal (CSI-RS), and a communications system. The transmission method comprises: transmitting a CSI-RS using a 32-port CSI-RS pattern or a 64-port CSI-RS pattern, wherein the 32-port CSI-RS pattern or the 64-port CSI-RS pattern is formed in one or more of the following manners: aggregating CSR-RSs of low port number on two or more subframes, aggregating CSI-RSs of low port number on two or more resource blocks, or increasing the number of resource elements for transmitting CSI-RSs in the subframes. Hence, 32 antenna ports or even 64 antenna ports can be configured on limited radio resources, and the spatial resolution of a system can be improved.
