13. An apparatus to be implemented in a user equipment (UE), the apparatus comprising:
processing circuitry to encode a message to include positioning reference signal (PRS) information related to an inter-radio access technology (RAT) positioning measurement to be performed by the UE, the PRS information to include an indication of a PRS offset; and
interface circuitry coupled with the processing circuitry to receive the encoded message and provide the encoded message to a radio-frequency front end for transmission to a serving next generation nodeB (gNB).
14. The apparatus of claim 13 , wherein the message is to further include an indication of: a measurement gap repetition periodicity (MGRP), a measurement gap length (MGL), a measurement gap offset, a measurement gap pattern identifier, or measurement gap type.
15. The apparatus of claim 13 , wherein the PRS information is to further include a positioning reference signal time duration or a positioning reference signal carrier frequency.
16. The apparatus of claim 13 , wherein the message includes an indication that a purpose of a measurement gap is for a positioning measurement.
17. The apparatus of claim 13 , wherein the message includes an indication of a priority associated with a measurement gap request.
18. One or more non-transitory, computer-readable media having instructions that, when executed, cause a next generation nodeB (gNB) to:
receive, from a user equipment (UE), positioning information that includes inter-radio access technology (RAT) reference signal time difference (RSTD) information; and
configure, based on the positioning information, a measurement gap for the UE to perform inter-RAT RSTD measurements with respect to an evolved universal terrestrial radio access network (E-UTRAN) cell,
wherein the inter-RAT RSTD information includes an indication of a carrier frequency or an indication of a positioning reference signal (PRS) offset.
19. The one or more non-transitory, computer-readable media of claim 18 , wherein the gNB is to provide a new radio standalone cell.
