INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A method for positioning in a mobile communication system are provided. Method for positioning includes receiving from a base station a SIB1 comprising a first scheduling information and a second scheduling information, acquiring a SI, transmitting to the base station a UECapabilityInformation the UECapabilityInformation includes a capability information related to PRS, transmitting to a LMF a provideCapabilities including a capability information related to SRS, transmitting to the LMF a RequestAssistanceData comprising a physical cell identity of Primary Cell (PCell) and a second identifier related to a second PRS data of the one or more second PRS data, receiving from the LMF a ProvideAssistanceData including a first PRS data the first PRS data includes a first identifier and one or more nr-DL-PRS-ResourceSet, receiving a RRCRelease including an information related to SRS transmission in RRC_INACTIVE, transmitting a positioning SRS in RRC_INACTIVE state and transmitting to the LMF a ProvideLocationInformation. ## Claims ### Claim 1 A method by a terminal, the method comprising: receiving, by the terminal from a base station, a System Information (SI) that comprises at least one first Positioning Reference Signal (PRS) data, wherein the first PRS data comprises: a first identifier; and configuration parameters for one or more PRS resource set; transmitting, by the terminal to a Location Management Function (LMF), a RequestAssistanceData, wherein the RequestAssistanceData comprises: a physical cell identifier of Primary Cell (PCell); and the first identifier; receiving, by the terminal from the LMF, a ProvideAssistanceData that comprises a second PRS data, wherein the second PRS data comprises: a second identifier; and configuration parameters for one or more PRS resource sets nr-DL-PRS-ResourceSetList; performing, by the terminal, measurement based on the second PRS data; and transmitting, by the terminal to the LMF, a ProvideLocationInformation. ### Claim 2 (depends on 1) The method of claim 1, wherein the RequestAssistanceData further comprises information for type of a requested assistance data. ### Claim 3 (depends on 1) The method of claim 1, wherein the RequestAssistanceData further comprises a specific field to request a third PRS data. ### Claim 4 (depends on 3) The method of claim 3, wherein the third PRS data comprises one or more base station identifiers and configuration parameters for one or more PRS resource sets. ### Claim 5 (depends on 4) The method of claim 4, wherein a validity of the third PRS data is determined based on the one or more base station identifiers. ### Claim 6 (depends on 3) The method of claim 3, wherein the specific field in the RequestAssistanceData is: present in case that the terminal requests the third PRS data; and absent in case that the terminal does not request the third PRS data. ### Claim 7 (depends on 1) The method of claim 1, wherein the ProvideAssistanceData further comprises parameters for one or more positioning methods. ### Claim 8 (depends on 1) The method of claim 1, wherein the PRS resource set comprises one or more PRS resources. ### Claim 9 (depends on 1) The method of claim 1, wherein the configuration parameters for PRS resource set comprises one or more sets of: code sequence information; starting slot; and Quasi-Collocation information. ### Claim 10 (depends on 1) The method of claim 1, wherein the ProvideLocationInformation comprises: one or more second identifiers; and arrival time difference of PRSs. ### Claim 11 (depends on 1) The method of claim 1, wherein a part of the ProvideLocationInformation is transmitted in a Medium Access Control (MAC) Protocol Data Unit (PDU). ### Claim 12 (depends on 11) The method of claim 11, wherein the MAC PDU comprises: a first MAC subPDU; a second MAC subPDU; and a third MAC subPDU. ### Claim 13 (depends on 12) The method of claim 12 wherein: the first MAC subPDU comprises a Signaling Radio Bearer0 (SRB0) message; the second MAC subPDU comprises the part of the ProvideLocationInformation; and the third MAC subPDU comprises Buffer Status Report (BSR). ### Claim 14 (depends on 12) The method of claim 12, wherein the first MAC subPDU and the second MAC subPDU and the third MAC subPDU are multiplexed in the MAC PDU in the order. ### Claim 15 (depends on 12) The method of claim 12, wherein a specific field is: comprised in the second MAC subPDU; and not comprised in the first MAC subPDU and the third MAC subPDU. ### Claim 16 (depends on 15) The method of claim 15, wherein the specific field indicates length of payload. ### Claim 17 (depends on 12) The method of claim 12, wherein: payload of the first MAC subPDU is not ciphered; payload of the second MAC subPDU is ciphered; and payload of the third MAC subPDU is not ciphered. ### Claim 18 (depends on 1) The method of claim 1, wherein: first capability parameter for PRS is reported to the base station; and second capability parameter for PRS is reported to the LMF. ### Claim 19 (depends on 18) The method of claim 18, wherein the first capability parameter indicates one or more measurement gap patterns for PRS measurement supported by the terminal. ### Claim 20 (depends on 18) The method of claim 18, wherein the second capability parameter indicates support of PRS measurement in RRC_INACTIVE state. ### Claim 21 (depends on 1) The method of claim 1, wherein: a third capability parameter is reported to the LMF; and the third capability parameter is related to measurement result report. ### Claim 22 A terminal comprising: a transceiver, a memory, and a controller coupled to the transceiver and the memory, wherein the controller is configured to cause the terminal to: receive from a base station a System Information (SI) that comprises at least one first Positioning Reference Signal (PRS) data, wherein the first PRS data comprises: a first identifier; and configuration parameters for one or more PRS resource set; transmit to a Location Management Function (LMF) a RequestAssistanceData, wherein the RequestAssistanceData comprises: a physical cell identifier of Primary Cell (PCell); and the first identifier; receive by the terminal from the LMF a ProvideAssistanceData that comprises a second PRS data wherein the second PRS data comprises: a second identifier; and configuration parameters for one or more PRS resource sets; perform measurement based on the second PRS data; and transmit, by the terminal to the LMF, a ProvideLocationInformation.
