Title:
METHOD AND APPARATUS FOR INDICATING INFORMATION OF ANTENNA PORT, COMMUNICATION DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/092477
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a method for indicating information of a demodulation reference signal (DMRS) port. The method is executed by an access network device. The method comprises: sending indication information to a terminal, wherein the indication information is used for indicating information of a DMRS port of a second-type DMRS. Here, since the indication information indicates the information of the DMRS port of the second-type DMRS, after receiving the indication information, the terminal can determine the DMRS port according to the information of the DMRS port of the second-type DMRS indicated by the indication information; and compared with the case where only a DMRS port of a first-type DMRS can be determined, when the DMRS port of the second-type DMRS is present, the terminal can clearly determine DMRS ports of different antenna signal types, and perform communications using corresponding DMRS ports, thereby achieving higher adaptability, and making wireless transmission based on DMRS ports more reliable.
