Abstract
A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes receiving second PRS data via system information, reporting capability related to PRS measurement in RRC_CONNECTED and capability related to PRS measurement in RRC_INACTIVE, transmitting requesting activation of the second PRS data, receiving third PRS data via dedicate message, determining validity of the PRS data, transmitting time pattern for PRS in via dedicate message, receiving first PRS data via dedicate message and reporting the measurement results.
Claims15
A method performed by a terminal, the method comprising:
- transmitting, by the terminal via uplink wireless channel, a first uplink message, wherein the first uplink message comprises a time pattern information for Positioning Reference Signal (PRS);
- receiving, by the terminal via downlink wireless channel, a first downlink message, wherein the first downlink message comprises a PRS data, wherein the PRS data comprises a first identifier and one or more parameter sets for PRS resource set;
- receiving, by the terminal via downlink wireless channel, a second downlink message, wherein the second downlink message comprise a counter;
- and
- transmitting, by the terminal via uplink wireless channel, a second uplink message, wherein the second uplink message comprises the first identifier and a time difference between one or more Transmission Reception Points (TRPs),
- wherein the second uplink message is ciphered based on a specific security key, and
- wherein the specific security key is determined based on:
- the counter indicated in the second downlink message;
- and
- a stored key.
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:
- transmit via uplink wireless channel a first uplink message, wherein the first uplink message comprises a time pattern information for Positioning Reference Signal (PRS);
- receive via downlink wireless channel a first downlink message, wherein the first downlink message comprises a PRS data, wherein the PRS data comprises a first identifier and one or more parameter sets for PRS resource set;
- receive via downlink wireless channel a second downlink message, wherein the second downlink message comprise a counter;
- and
- transmit via uplink wireless channel a second uplink message, wherein the second uplink message comprises the first identifier and a time difference between one or more Transmission Reception Points (TRPs),
- wherein the second uplink message is ciphered based on a specific security key, and
- wherein the specific security key is determined based on:
- the counter indicated in the second downlink message;
- and
- a stored key.
