A target user device for a locally assisted positioning procedure may receive a trigger event to initiate positioning of the target user device, the trigger event originating from a location management function in relation to the locally assisted positioning procedure. The target user device may transmit at least one local positioning aid request to one or more anchor user devices for the locally assisted positioning procedure, the at least one local positioning aid request indicating a need for the locally assisted positioning procedure for the positioning of the target user device. Devices, methods, and computer programs are disclosed. ## Claims ### Claim 1 An anchor user device for a locally assisted positioning procedure, comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the anchor user device at least to: receive a local positioning aid request associated with a target user device for the locally assisted positioning procedure, the local positioning aid request indicating a need for the locally assisted positioning procedure for positioning of the target user device; and transmit, to the target user device, a local positioning aid response to the local positioning aid request, wherein the local positioning aid response comprises location data associated with the anchor user device, and wherein the local positioning aid response further comprises at least one of the following: a rejection indication to the local positioning aid request; an acknowledgement to the local positioning aid request; and an indication that the location data associated with the anchor user device is to be transmitted to a location management function. ### Claim 2 (depends on 1) The anchor user device according to claim 1, wherein the anchor user device is further caused at least to: obtain the location data associated with the anchor user device. ### Claim 3 (depends on 1) The anchor user device according to claim 1, wherein the anchor user device is further caused at least to: transmit a positioning protocol request to the location management function; and receive, from the location management function, the location data associated with the anchor user device. ### Claim 4 (depends on 1) The anchor user device according to claim 1, wherein the anchor user device is further caused at least to: obtain the location data associated with the anchor user device; and transmit the location data associated with the anchor user device, to the location management function. ### Claim 5 (depends on 1) The anchor user device according to claim 1, wherein the anchor user device is further caused at least to: transmit positioning protocol signaling to the location management function, the positioning protocol signaling enabling the location management function obtaining the location data associated with the anchor user device based on radio signal measurement data. ### Claim 6 A method performed by an anchor user device, comprising: receiving a local positioning aid request associated with a target user device for a locally assisted positioning procedure, the local positioning aid request indicating a need for the locally assisted positioning procedure for positioning of the target user device; and transmitting to the target user device, a local positioning aid response in response to the local positioning aid request, wherein the local positioning aid response comprises location data associated with the anchor user device, and wherein the local positioning aid response further comprises at least one of the following: a rejection indication to the local positioning aid request; an acknowledgement to the local positioning aid request; and an indication that the location data associated with the anchor user device is to be transmitted to a location management function. ### Claim 7 (depends on 6) The method according to claim 6, further comprising: obtaining the location data associated with the anchor user device. ### Claim 8 (depends on 6) The method according to claim 6, further comprising: transmitting a positioning protocol request to the location management function; and receiving, from the location management function, the location data associated with the anchor user device. ### Claim 9 (depends on 6) The method according to claim 6, further comprising: obtaining the location data associated with the anchor user device; and transmitting the location data associated with the anchor user device, to the location management function. ### Claim 10 (depends on 6) The method according to claim 6, further comprising: transmitting positioning protocol signaling to the location management function, the positioning protocol signaling enabling the location management function obtaining the location data associated with the anchor user device based on radio signal measurement data. ### Claim 11 A volatile memory device comprising instructions for causing an apparatus to perform at least the following: receiving a local positioning aid request associated with a target user device for a locally assisted positioning procedure, the local positioning aid request indicating a need for the locally assisted positioning procedure for positioning of the target user device; and transmitting to the target user device, a local positioning aid response in response to the local positioning aid request, wherein the local positioning aid response comprises location data associated with an anchor user device, and wherein the local positioning aid response further comprises at least one of the following: a rejection indication to the local positioning aid request; an acknowledgement to the local positioning aid request; and an indication that the location data associated with the anchor user device is to be transmitted to a location management function. ### Claim 12 (depends on 11) The volatile memory device according to claim 11, wherein the instruction further causing to perform: obtaining the location data associated with the anchor user device. ### Claim 13 (depends on 11) The volatile memory device according to claim 11, wherein the instruction further causing to perform: transmitting a positioning protocol request to the location management function; and receiving, from the location management function, the location data associated with the anchor user device. ### Claim 14 (depends on 11) The volatile memory device according to claim 11, wherein the instruction further causing to perform: obtaining the location data associated with the anchor user device; and transmitting the location data associated with the anchor user device, to the location management function. ### Claim 15 (depends on 11) The volatile memory device according to claim 11, wherein the instruction further causing to perform: transmitting positioning protocol signaling to the location management function, the positioning protocol signaling enabling the location management function obtaining the location data associated with the anchor user device based on radio signal measurement data.
