Title:
UPLINK REFERENCE SIGNAL SENDING METHOD, UPLINK REFERENCE SIGNAL RECEIVING METHOD, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/223084
Kind Code:
A1
Abstract:
The present application provides an uplink reference signal sending method, an uplink reference signal receiving method, and a communication device, for obtaining accurate uplink channel measurement results. The method comprises: determining, according to a resource allocation rule, downlink reference signal resources corresponding to multiple first resource blocks for carrying uplink reference signals in multiple uplink reference signal resources, each uplink reference signal resource comprising one or more first resource blocks; and determining, on the basis of the downlink reference signal resource corresponding to each first resource block, the precoding corresponding to each first resource block, the precoded uplink reference signal sent thereafter being obtained by precoding the uplink reference signal on the basis of the precoding corresponding to each first resource block. Then, the precoding corresponding to each second resource for uplink data transmission can be determined according to the corresponding relationship between the first resource and the precoding. Therefore, the corresponding relationship between the first resource and precoding as well as the corresponding relationship between the second resource and precoding are corresponding, thus facilitating reasonable scheduling for uplink data transmission.
