Abstract
A method and apparatus for positioning in a mobile communication system are provided. 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.
Claims12
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.
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.
