Positioning method, communication device and medium

A communication device, being a first device, comprising a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or the instructions, when executed by the processor, cause the communication device to perform:

• performing a target operation, to assist a first terminal in positioning, wherein
• the target operation comprises at least one of:
• transmitting a target message, or transmitting a first sidelink positioning reference signal (SL-PRS);
• wherein the target message comprises:
• a positioning request and time domain offset information;
• the first SL-PRS is used for determining:
• location information of the first terminal and/or second terminal, and/or SL-PRS measurement information;
• and
• the second terminal is a peer terminal that performs sidelink (SL) communication or SL positioning with the first terminal;
• wherein the target message is transmitted through sidelink control information (SCI);
• wherein the SCI is dedicated to scheduling an SL-PRS;
• the positioning request comprises SL-PRS request indication information;
• wherein the SL-PRS request indication information indicates whether the SL-PRS is requested;
• and
• the time domain offset information comprises offset information between the SCI and the SL-PRS;
• wherein the program or the instructions, when executed by the processor, cause the communication device to further perform:
• obtaining a second parameter provided by a higher layer, wherein the second parameter is used for selecting a target first resource, and the target first resource is used for transmitting the first SL-PRS;
• wherein
• the second parameter comprises:
• indication information of at least one first resource;
• wherein the target first resource is one or more resources in the at least one first resource;
• and
• a dedicated resource pool parameter of at least one SL-PRS.

A non-transitory readable storage medium, storing a program or instructions, wherein the program or the instructions, when executed by a processor of a first device, cause the first device to perform:

• performing a target operation, to assist a first terminal in positioning, wherein
• the target operation comprises at least one of:
• transmitting a target message, or transmitting a first sidelink positioning reference signal (SL-PRS);
• wherein the target message comprises a positioning request and time domain offset information;
• the first SL-PRS is used for determining:
• location information of the first terminal and/or second terminal, and/or SL-PRS measurement information;
• and
• the second terminal is a peer terminal that performs sidelink (SL) communication or SL positioning with the first terminal;
• wherein the target message is transmitted through sidelink control information (SCI);
• wherein the SCI is dedicated to scheduling an SL-PRS;
• the positioning request comprises SL-PRS request indication information;
• wherein the SL-PRS request indication information indicates whether the SL-PRS is requested;
• and
• the time domain offset information comprises offset information between the SCI and the SL-PRS;
• wherein the program or the instructions, when executed by the processor, cause the first device to further perform:
• obtaining a second parameter provided by a higher layer, wherein the second parameter is used for selecting a target first resource, and the target first resource is used for transmitting the first SL-PRS;
• wherein
• the second parameter comprises:
• indication information of at least one first resource;
• wherein the target first resource is one or more resources in the at least one first resource;
• and
• a dedicated resource pool parameter of at least one SL-PRS.
