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 including a type1 identifier and one or more PRS resource set information, receiving from a base station a type2 assistance data including a validity information and a second type1 assistance data, determining based on the validity information and New Radio (NR) Cell Global identity of serving cell whether the second type1 assistance data is valid, receiving from the base station a RRCRelease including a SuspendConfig including a information indicating small data transmission is configured for Signaling Radio Bearer2 (SRB2), transmitting in RRC_INACTIVE a first message.

Claims (20)

1 . A method by a terminal, the method comprising:

receiving, by the terminal from a base station, a first type 1 assistance data, the first type 1 assistance data includes a type 1 identifier and one or more Positioning Reference Signal (PRS) resource set information;

receiving, by the terminal from the base station, a type2 assistance data, the type2 assistance data includes a validity information and a second type 1 assistance data;

determining, by the terminal based on the validity information and New Radio (NR) Cell Global identity of serving cell, the second type 1 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, a first message,

wherein at least a part of the first message is transmitted as included in a first Medium Access Control (MAC) Protocol Data Unit (PDU) and the first MAC PDU includes a ResumeRequest,

wherein the first message includes PRS measurement result, and

wherein the ResumeRequest in the first MAC PDU is not ciphered and the first message in the first MAC PDU is ciphered.

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 type 1 assistance data, the first type 1 assistance data includes a type1 identifier and one or more Positioning Reference Signal (PRS) resource set information,

receive 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 New Radio (NR) Cell Global identity of serving cell, 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, a first message,

wherein at least a part of the first message is transmitted as included in a first Medium Access Control (MAC) Protocol Data Unit (PDU) and the first MAC PDU includes a ResumeRequest,

wherein the first message includes PRS measurement result, and

wherein the ResumeRequest in the first MAC PDU is not ciphered and the first message in the first MAC PDU is ciphered.
