Method for positioning includes receiving SIB1, acquiring SI, transmitting a UECapabilityInformation, transmitting a provideCapabilities and transmitting a RequestAssistanceData, The ProvideAssistanceData includes a first PRS data and a data related to the second PRS data. The UECapabilityInformation includes a second capability information related to PRS measurement. The provideCapabilities includes a first capability information related to PRS measurement. ## Claims ### Claim 1 A method performed by a wireless device, the method comprising: receiving from a base station a System Information (SI), wherein the SI comprises one or more second positioning reference signal (PRS) data, wherein each of the one or more second PRS data comprises a second identifier and one or more downlink PRS resource sets; transmitting, by the wireless device to the base station, a UECapability Information, wherein the UECapabilityInformation comprises a second capability information related to PRS measurement; transmitting, by the wireless device to a Location Management Function (LMF), a provideCapabilities, wherein the provideCapabilities comprises a first capability information related to PRS measurement; receiving, by the wireless device from the base station, a Radio Resource Control (RRC) message instructing state transition to RRC_INACTIVE state, wherein the RRC message comprises a counter; and transmitting, by the wireless device to the LMF, an LTE Positioning Protocol (LPP) segment containing positioning measurement result, wherein the first capability information relates to PRS measurement in RRC_INACTIVE and the second capability information relates to PRS measurement in RRC_Connected. ### Claim 2 (depends on 1) The method of claim 1 further comprising: receiving, by the wireless device from the LMF, a ProvideAssistanceData, wherein the ProvideAssistanceData comprises a first PRS data, wherein the first PRS data comprises one or more downlink PRS resource sets and a first identifier. ### Claim 3 (depends on 2) The method of claim 2, wherein each of the one or more downlink PRS resource set comprises one or more downlink PRS resource, wherein each of the one or more downlink PRS resource comprises a sequence for the PRS resource and a starting slot for the PRS resource. ### Claim 4 (depends on 1) The method of claim 1, wherein the LPP segment comprises a time difference between one or more Transmission Reception Points (TRPs). ### Claim 5 (depends on 4) The method of claim 4, wherein the time difference between one or more TRPs is measured based on the first PRS data in RRC_INACTIVE. ### Claim 6 (depends on 1) The method of claim 1, wherein the transmitting LPP segment comprising: multiplexing a first Service Data Unit (SDU) and a second SDU in a Medium Access Control (MAC) Protocol Data Unit (PDU); and transmitting the MAC PDU. ### Claim 7 (depends on 6) The method of claim 6, wherein the first SDU comprises a Radio Resource Control message to request RRC connection resumption; and the second SDU comprises the LPP segment. ### Claim 8 (depends on 7) The method of claim 7, wherein the first SDU is not ciphered; and the second SDU is ciphered based on a security key determined based on the counter indicated in the RRC message instructing state transition to RRC_INACTIVE state. ### Claim 9 (depends on 6) The method of claim 6, wherein the multiplexing the first SDU and the second SDU in the MAC PDU comprises: locating in the MAC PDU in order: a first subheader for the first SDU; the first SDU; a second subheader for the second SDU; and the second SDU. ### Claim 10 (depends on 1) The method of claim 1, wherein the transmitting LPP segment comprising: multiplexing a first SDU and a second SDU and a third SDU in a MAC PDU; and transmitting the MAC PDU, wherein the third SDU comprises Buffer Status Report. ### Claim 11 (depends on 10) The method of claim 10, wherein the Buffer Status Report indicates Buffer Size corresponding to the remaining LPP segment. ### Claim 12 A wireless device comprising: a transceiver, a memory, and a controller coupled to the transceiver and the memory, wherein the controller is configured to cause the wireless device to: receive from a base station a System Information (SI), wherein the SI comprises a one or more second positioning reference signal (PRS) data, wherein each of the one or more second PRS data comprises a second identifier and one or more downlink PRS resource sets, transmit to the base station a UECapabilityInformation, wherein the UECapabilityInformation comprises a second capability information related to PRS measurement, transmit to a Location Management Function (LMF) a provideCapabilities, wherein the provideCapabilities comprises a first capability information related to PRS measurement, receive from the base station a Radio Resource Control (RRC) message instructing state transition to RRC_INACTIVE state, wherein the RRC message comprises a counter, and transmit to the LMF an LTE Positioning Protocol (LPP) segment containing positioning measurement result, wherein the first capability information relates to PRS measurement in RRC_INACTIVE and the second capability information relates to PRS measurement in RRC_Connected.
