1. A method performed by a terminal, the method comprising:
receiving, by the terminal via a wireless channel, a first control message, wherein the first control message comprises assistance data, wherein the assistance data comprises:
a first identifier;
one or more nr-DL-PRS-ResourceSet; and
validity information, wherein the validity information comprises one or more second identifiers;
determining, by the terminal, validity of the one or more nr-DL-PRS-ResourceSet based on the validity information; and
transmitting, by the terminal via the wireless channel, a Medium Access Control (MAC) Protocol Data Unit (PDU), wherein the MAC PDU comprises:
a segment of a second control message for providing location information; and
a Buffer Status Report (BSR),
wherein the BSR comprises an index for buffer size and an identifier of a logical channel group,
wherein the index is determined based on an amount of data corresponding to remaining segments of the second control message,
wherein:
the logical channel group is associated with a third identifier and a fourth identifier;
the identifier of the logical channel group is set to the fourth identifier;
the third identifier is configured in RRC_Connected state; and
the fourth identifier is predefined, and
wherein the one or more second identifiers comprise:
a mobile country code;
a mobile network code; and
cell identity.
