Prs resource indication method and apparatus in sidelink communication, storage medium and terminal
View Patent ↗A Positioning Reference Signal (PRS) resource indication method and apparatus in sidelink communication, a storage medium and a terminal are provided. The method includes: sending resource indication information to a receiving User Equipment (UE), to enable the receiving UE to acquire a target position of a PRS resource based on the resource indication information and preset information to receive a PRS at the target position; wherein the resource indication information indicates a position of the PRS resource and/or a position of a Physical Sidelink Shared Channel (PSSCH) resource, and the preset information includes at least a relationship between the PSSCH resource and the PRS resource.
1. A Positioning Reference Signal (PRS) resource indication method in sidelink communication, comprising:
sending resource indication information to a receiving User Equipment (UE), to enable the receiving UE to acquire a target position of a PRS resource based on the resource indication information and preset information to receive a PRS at the target position;
wherein the resource indication information indicates a position of the PRS resource, and the preset information comprises at least a relationship between a Physical Sidelink Shared Channel (PSSCH) resource and the PRS resource,
the resource indication information indicates a frequency domain position of the PRS resource, and each frequency domain position comprises a frequency domain starting position, and
the resource indication information indicates the frequency domain position of the PRS resource by a preset number of bits.
2. The method according to claim 1 , wherein the preset information is configured by high-layer signaling which comprises at least one of Long Term Evolution Positioning Protocol (LPP), Radio Resource Control (RRC) signaling, Medium Access Control Element (MAC-CE), PC5-RRC signaling, or PC5-MAC-CE.
3. The method according to claim 1 , wherein the resource indication information is carried by SCI.
4. The method according to claim 3 , wherein the SCI comprises first stage SCI and/or second stage SCI.
5. The method according to claim 1 , wherein the position of the PSSCH resource and the position of the PRS resource are consecutive.
6. The method according to claim 1 , wherein there is a preset offset between the position of the PSSCH resource and the position of the PRS resource.
7. A non-transitory storage medium storing one or more programs, the one or more programs comprising computer instructions, which, when executed by a processor, cause the processor to:
send resource indication information to a receiving User Equipment (UE), to enable the receiving UE to acquire a target position of a Positioning Reference Signal (PRS) resource based on the resource indication information and preset information to receive a PRS at the target position;
wherein the resource indication information indicates a position of the PRS resource, and the preset information comprises at least a relationship between a Physical Sidelink Shared Channel (PSSCH) resource and the PRS resource,
the resource indication information indicates a frequency domain position of the PRS resource, and each frequency domain position comprises a frequency domain starting position, and
the resource indication information indicates the frequency domain position of the PRS resource by a preset number of bits.
8. A terminal comprising a memory and a processor, wherein the memory stores one or more programs, the one or more programs comprising computer instructions, which, when executed by the processor, cause the processor to:
send resource indication information to a receiving User Equipment (UE), to enable the receiving UE to acquire a target position of a Positioning Reference Signal (PRS) resource based on the resource indication information and preset information to receive a PRS at the target position;
wherein the resource indication information indicates a position of the PRS resource, and the preset information comprises at least a relationship between a Physical Sidelink Shared Channel (PSSCH) resource and the PRS resource,
the resource indication information indicates a frequency domain position of the PRS resource, and each frequency domain position comprises a frequency domain starting position, and
the resource indication information indicates the frequency domain position of the PRS resource by a preset number of bits.
9. The terminal according to claim 8 , wherein the preset information is configured by high-layer signaling which comprises at least one of Long Term Evolution Positioning Protocol (LPP), Radio Resource Control (RRC) signaling, Medium Access Control Element (MAC-CE), PC5-RRC signaling, or PC5-MAC-CE.
10. The terminal according to claim 8 , wherein the resource indication information is carried by SCI.
11. The terminal according to claim 10 , wherein the SCI comprises first stage SCI and/or second stage SCI.
12. The terminal according to claim 8 , wherein the position of the PSSCH resource and the position of the PRS resource are consecutive.
13. The terminal according to claim 8 , wherein there is a preset offset between the position of the PSSCH resource and the position of the PRS resource.
14. The non-transitory storage medium according to claim 7 , wherein the preset information is configured by high-layer signaling which comprises at least one of Long Term Evolution Positioning Protocol (LPP), Radio Resource Control (RRC) signaling, Medium Access Control Element (MAC-CE), PC5-RRC signaling, or PC5-MAC-CE.
15. The non-transitory storage medium according to claim 7 , wherein the resource indication information is carried by SCI.
