## Abstract

A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes receiving from a base station a first type1 assistance data, receiving from the base station a type2 assistance data, the type2 assistance data includes a validity information and a second type1 assistance data, determining based on the validity information and a New Radio (NR) cell global identifier of serving cell whether the second type1 assistance data is valid, receiving from the base station a RRCRelease, transmitting in RRC_INACTIVE state a ProvideLocationInformation. At least a part of the ProvideLocationInformation is transmitted in a first Medium Access Control (MAC) Protocol Data Unit (PDU) and the first MAC PDU includes a ResumeRequest.

## Claims

### Claim 1

A method by a terminal, the method comprising:
receiving by the terminal from a base station a first type1 assistance data, the first type1 assistance data includes a first type identifier and one or more Positioning Reference Signal (PRS) resource set;
receiving by the terminal from the base station a type2 assistance data, the type2 assistance data includes a validity information and a second type1 assistance data;
determining by the terminal based on the validity information and a New Radio (NR) cell global identifier of serving cell whether the second type1 assistance data is valid;
receiving by the terminal from the base station a RRCRelease, the RRCRelease includes a SuspendConfig, the SuspendConfig includes information indicating that small data transmission is configured for Signaling Radio Bearer2 (SRB2); and
transmitting by the terminal in RRC_INACTIVE state to the base station a part of a ProvideLocationlnformation,
wherein the part of the ProvideLocationlnformation is transmitted in a first Medium Access Control (MAC) Protocol Data Unit (PDU), the first MAC PDU includes a ResumeRequest.

### Claim 2

A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal, and
a controller configured to control the transceiver to:
receive from a base station a first type1 assistance data, the first type1 assistance data includes a first type identifier and one or more Positioning Reference Signal (PRS) resource set;
receiving from the base station a type2 assistance data, the type2 assistance data includes a validity information and a second type1 assistance data;
determine based on the validity information and a New Radio (NR) cell global identifier of serving cell whether the second type1 assistance data is valid;
receive from the base station a RRCRelease, the RRCRelease includes a SuspendConfig, the SuspendConfig includes information indicating that small data transmission is configured for Signaling Radio Bearer2 (SRB2); and
transmit in RRC_INACTIVE state to the base station a part of a ProvideLocationlnformation,
wherein the part of the ProvideLocationlnformation is transmitted in a first Medium Access Control (MAC) Protocol Data Unit (PDU), the first MAC PDU includes a ResumeRequest.
