Methods and apparatus for supporting positioning service continuity

The method of claim 20, wherein, on condition that the second PRS measurements do not satisfy a PRS ME threshold:

• sending, to a first NE associated with the second cell, a request for a further MG configuration;
• receiving, information indicating the further MG configuration;
• performing third PRS measurements on a transmission from the second cell using the second PRS configuration and the further MG configuration;
• and
• sending, to a second NE associated with the second cell, further information indicating any of:
• (1) the third PRS measurements, (2) the second PRS configuration, and/or (3) a time when the WTRU started to use the second PRS configuration.

The method of claim 20, further comprising:

• triggering the performing of the second PRS measurements in response to the ME, wherein:
• the performing of:
• (1) the first PRS measurements uses the first PRS configuration and the MG configuration before the ME is performed and (2) the second PRS measurements uses the first PRS configuration and the MG configuration during at least a first part of the ME,
• the method includes performing further PRS measurements using the second PRS configuration and the second MG configuration (1) during at least a second part of the ME and (2) after the ME is performed.

The method of claim 20, comprising:

• receiving, by the WTRU, information associated with:
• (1) a first positioning operation, (2) a second positioning operation and (3) one or more trigger conditions for starting and/or stopping usage of the second positioning operation;
• and
• on condition that the one or more trigger conditions are satisfied to start using the second positioning operation, initiating use of the second positioning operation,
• wherein:
• the performing of the first PRS measurements uses the first PRS configuration associated with the first positioning operation, and
• the performing of the second PRS measurements uses the second PRS configuration associated with the second positioning operation.

A wireless transmit/receive unit (WTRU) including any of a processor, a transceiver and memory, the circuitry configured to:

• receive information indicating:
• (1) a first Positioning Reference Signal (PRS) configuration associated with a first cell, (2) a second PRS configuration associated with a second cell, and (3) a measurement gap (MG) configuration;
• perform first PRS measurements on a first transmission from the first cell using the first PRS configuration and the MG configuration;
• send, to a first Network Entity (NE) associated with the first cell, a request including information indicating to maintain, after a mobility event (ME) associated with the second cell is performed, the MG configuration;
• and
• receive information indicating:
• (1) to perform the ME associated with the second cell, and (2) to maintain, after the ME is performed, the MG configuration.
