Title:
SIDELINK POSITIONING REFERENCE SIGNAL SENDING METHOD AND APPARATUS, AND SIDELINK POSITIONING REFERENCE SIGNAL RECEIVING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/011347
Kind Code:
A1
Abstract:
Provided in the present application are a sidelink positioning reference signal (SL PRS) sending method and apparatus, and a sidelink positioning reference signal (SL PRS) receiving method and apparatus. The sending method applied to a first terminal comprises: acquiring a time-frequency resource configuration parameter of an SL PRS; and determining a first resource, and sending, on the first resource, the SL PRS, or the SL PRS and first indication information according to the time-frequency resource configuration parameter, wherein the first indication information is used for indicating transmission parameter information on the first resource. In the embodiments of the present application, a time-frequency resource configuration parameter of an SL PRS is acquired, and according to the time-frequency resource configuration parameter, the SL PRS is carried on a first resource and is then sent and received, and can be matched with first indication information, thereby facilitating the transmission of the SL PRS when no base station participates in scheduling and the structural form of a physical layer channel is different from an existing uplink and downlink, and facilitating the positioning of a sidelink according to the SL PRS.
