The mobile radio network nodes may be air, land, or water-borne (e.g., mounted on drones, trains, boats, planes, automobiles, or the like). The UEs to be located may be a wide range of devices such as emergency transmitters, mobile phones, simple sensor nodes, and other Internet of Things (IoT) devices.

A method and apparatus for processing location information and a non-transitory computer-readable storage medium are disclosed. The method may include: transmitting, by a location management function (LMF) server, location request information to a serving cell of a terminal device, the location request information at least comprising sounding reference signal (SRS) configuration recommendation information; receiving, by the LMF server, location response information transmitted by the serving cell, the location response information at least comprising SRS configuration determination information; and transmitting, by the LMF server, measurement request information to a transmission receive point (TRP), the measurement request information comprising the SRS configuration determination information.

A method for locating a UE includes: acquiring a relative location between an assistant UE and a target UE, reported by the assistant UE, and determining a location of the target UE based on a location of the assistant UE and the relative location.

A UE includes: a transceiver; a memory; and a processor configured to: receive first and second discontinuous reception configurations for first and second discontinuous reception groups; receive first and second positioning signal configurations for first and second positioning signals associated with the first and second discontinuous reception groups, respectively; measure the first positioning signal during a first active time of the first discontinuous reception group; and measure the second positioning signal during a fixed second active time or during a variable third active time, the fixed second active time having a fixed duration of the second discontinuous reception group and the variable third active time having a variable duration of the second discontinuous reception group.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, during one or more time units up to a first time, a configuration to provide a positioning state information (PSI) report, measures, after the first time up to a second time, one or more positioning reference signal (PRS) transmissions, and transmits, at a third time after the second time, the PSI report on an uplink physical channel, the PSI report including measurements of the one or more PRS resources, wherein a length of time between the second time and the third time is greater than a timing requirement Z′.

Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.

According to an embodiment of the present disclosure, a method of performing sidelink communication by a first device is provided. The method may include the steps of: transmitting a PRS to multiple servers; receiving, from one anchor server among the multiple servers, information relating to RSTD values indicating differences between time points at which the multiple servers have received the PRS and information relating to an absolute position of each of the multiple servers; and determining a position of the first device on the basis of the information relating to the RSTD values and the information relating to the absolute position of each of the multiple servers.
