Title:
METHOD FOR SENDING DEMODULATION REFERENCE SIGNAL AND METHOD FOR RECEIVING DEMODULATION REFERENCE SIGNAL, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/141601
Kind Code:
A1
Abstract:
The present application provides a method for sending a DMRS, a method for receiving a DMRS, and a communication device. The method for sending a DMRS comprises: receiving indication information for indicating a scheduled DMRS port; and sending a DMRS on the scheduled DMRS port. The scheduled DMRS port belongs to a DMRS port set, the DMRS port set contains M DMRS ports, the M DMRS ports correspond to a first time domain location and a second time domain location, and a first DMRS port set corresponding to the first time domain location is different from a second DMRS port set corresponding to the second time domain location. In this way, different DMRS port sets are mapped respectively at the first time domain location and the second time domain location, so that more orthogonal DMRS ports can be supported, improving system capacity.
