1. A method performed by a terminal, the method comprising:
receiving, by the terminal from a base station, a System Information Block 1 (SIB1), wherein the SIB1 comprises a first scheduling information and a second scheduling information, the first scheduling information comprises a System Information (SI) window length and one or more scheduling information, the second scheduling information comprises one or more positioning scheduling information, each of one or more positioning scheduling information corresponds to a SI, the SI includes a first positioning SIB or a second positioning SIB, the first positioning SIB includes a first Positioning Reference Signal (PRS) data, the second positioning SIB includes a second PRS data, the first PRS data comprises one or more nr-DL-PRS-ResourceSets, and the second PRS data comprises one or more nr-DL-PRS-ResourceSets and an identifier;
transmitting, by the terminal to request the second positioning SIB, a first uplink message based at least in part on the second scheduling information in case that the terminal is in RRC_INACTIVE;
acquiring, by the terminal, the SI based on the first scheduling information and the second scheduling information, wherein the SI includes the second positioning SIB; and
transmitting, by the terminal, a second uplink message, wherein the second uplink message includes a physical cell identity of Primary Cell, the identifier related to the second PRS data, and an indication that a third PRS data is requested,
wherein the first PRS data indicates a PRS that is being transmitted,
