Methods and apparatuses for enabling sidelink positioning for location of out-ofcoverage wireless transmit/receive units

A method implemented by a first wireless transmit/receive unit (WTRU), the method comprising:

• receiving a first sidelink (SL) positioning request from a second WTRU, wherein the first SL positioning request comprises security information for validating the first SL positioning request and configuration information that includes one or more parameters to derive security credentials for validating the security information in the first SL positioning request;
• sending a first SL positioning response to the second WTRU, wherein the first SL positioning response is sent based on validation of the first SL positioning request using at least the security information;
• and
• performing an SL positioning with the second WTRU.

A first wireless transmit/receive unit (WTRU) comprising:

• a processor configured to:
• receive a first sidelink (SL) positioning request from a second WTRU, wherein the first SL positioning request comprises security information for validating the first SL positioning request and configuration information that includes one or more parameters to derive security credentials for validating the security information in the first SL positioning request;
• send a first SL positioning response to the second WTRU, wherein the first SL positioning response is sent based on validation of the first SL positioning request using at least the security information;
• and
• perform an SL positioning with the second WTRU.
