Method and apparatus for positioning terminal in wireless communication system

A terminal comprising:

• a transceiver;
• and
• a processor coupled with the transceiver,
• wherein the transceiver is configured to:
• receive, from a serving base station, a first message including at least one of positioning reference signal (PRS) information of the serving base station and PRS information of a neighbor base station,
• receive, by the terminal from the serving base station, a PRS of the serving base station, and
• receive, by the terminal from the neighbor base station based on the first message, a PRS of the neighbor base station,
• wherein the processor is configured to estimate a location of the terminal based on the PRS received from the serving base station and the PRS received from the neighbor base station,
• wherein the transceiver is further configured to transmit the estimated location information of the terminal, and
• wherein the PRS information of the neighbor base station includes a PRS beam direction of the neighbor base station and a PRS beam duration of the neighbor base station, and
• wherein the neighbor base station is selected, by the serving base station, based on a time at which transmission of the PRS from the neighbor base station starts.

A method comprising:

• selecting, by a serving base station, a neighbor base station based on a time at which a transmission of a positioning reference signal (PRS) from the neighbor base station starts;
• transmitting, by the serving base station, an assistance data request message to a server;
• receiving, by the serving base station, assistance data from the server,
• wherein the assistance data includes at least one of PRS information of the serving base station and PRS information of the neighbor base station;
• transmitting, by the serving base station to a terminal, a first message that includes at least one of PRS information of the base station, cell ID information of the base station, or PBCH information of the base station;
• and
• receiving, by the serving base station from the terminal, location information of the terminal and transmitting, to the server, the location information of the terminal,
• wherein the PRS information of the base station includes a PRS beam direction of the neighbor base station and a PRS beam duration of the base station.
