Claim 0:
1. A method by a terminal, the method comprising:
receiving, by the terminal, a System Information (SI), the SI includes a positioning system information block (SIB), the positioning SIB includes a second positioning reference signal (PRS) data, the second PRS data includes one or more nr-DL-PRS-ResourceSet and a second identifier;
transmitting, by the terminal to the base station, a UECapabilityInformation, the UECapabilityInformation includes a capability information indicating support of Sounding Reference Signal (SRS) for positioning in RRC_INACTIVE;
transmitting, by the terminal to a Location Management Function (LMF), a provideCapabilities, the provideCapabilities includes a capability information related to PRS in RRC_INACTIVE;
transmitting, by the terminal to the LMF, a RequestAssistanceData, the RequestAssistanceData includes a physical cell identity of Primary Cell (PCell) and the second identifier related to the second PRS data;
receiving, by the terminal from the LMF, a ProvideAssistanceData, the ProvideAssistanceData includes a first PRS data or a third PRS data, the first PRS data includes one or more nr-DL-PRS-ResourceSet and the first identifier, the third PRS data includes one or more nr-DL-PRS-ResourceSet and a third identifier and a validity information, the validity information includes one or more New Radio (NR) Cell Global Identities and indicates the RRS assistance data is valid within one or more cells indicated by the one or more NR Cell Global Identities;
receiving, by the terminal from the base station, a RRCRelease, the RRCRelease includes a one bit indication that indicates small data transmission via Signaling Radio Bearer2 (SRB2) is configured and information related to SRS transmission in RRC_INACTIVE;
transmitting, by the terminal, a positioning SRS in RRC_INACTIVE state; and
transmitting, by the terminal to the LMF, a ProvideLocationInformation in RRC_INACTIVE state, the ProvideLocationInformation includes at least a time difference between one or more TRPs and a first identifier or a third identifier,
wherein the second identifier is associated with one or more nr-DL-PRS-ResourceSets included in the positioning SIB and the third identifier is associated with one or more nr-DL-PRS-ResourceSets included in the ProvideAssistanceData, and
wherein the nr-DL-PRS-ResourceSet includes one or more dl-PRS-Resource, each of the one or more dl-PRS-Resource includes a sequence for PRS resource and a starting slot for PRS resource.
