1. An apparatus for a terminal in a wireless communication system, the apparatus comprising:
- a transceiver; and
at least one processor operatively coupled with the transceiver,wherein the at least one processor is configured to;
transmit a first signal for requesting positioning,receive positioning signals for positioning of the terminal from a first plurality of other terminals, the first plurality of other terminals comprising at least one position determined terminal with a determined position and an expiration time for the determined position,determine distance values between the terminal and the first plurality of other terminals based on the positioning signals, andif at least one of the distance values is greater than or equal to a threshold value, transmit a second signal for requesting positioning for receiving other positioning signals from a second plurality of other terminals except terminals whose expiration time has elapsed.

Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). In particular, the present invention relates to an apparatus and method for position measurement in a wireless communication system. An operating method of a terminal in the wireless communication system includes transmitting a signal for requesting for positioning, and receiving positioning signals for the positioning of the terminal from a plurality of other terminals.

10. An apparatus for a base station in a wireless communication system, the apparatus comprising:
-
a transceiver; and at least one processor operatively coupled with the transceiver, wherein the at least one processor is configured to; receive from a terminal a first signal for requesting positioning, transmit, to a first plurality of other terminals a second signal for requesting for transmission of a positioning signal for the positioning of the terminal, wherein the first plurality of other terminals comprises at least one position determined terminal with a determined position and an expiration time for the determined position, and receive, from the terminal, a third signal for requesting positioning for receiving positioning signals from a second plurality of other terminals except terminals whose expiration time has elapsed. - View Dependent Claims (11)

12. An apparatus for determining a position of a terminal in a wireless communication system, the apparatus comprising:
-
a transceiver; and at least one processor operatively coupled with the transceiver, wherein the at least one processor is configured to; acquire at least one positioning parameter regarding positions of a first plurality of other terminals, wherein the first plurality of other terminals comprises at least one position determined terminal with a determined position and an expiration time for the determined position, determine a first part of position information of the terminal based on the at least one positioning parameter, determine a second part of the position information of the terminal based on the first part of the position information, the position information is used for determining distance values between the terminal and the first plurality of other terminals, and if at least one of the distance values is greater than or equal to a threshold value, acquire at least one other positioning parameter regarding positions of a second plurality of other terminals except terminals whose expiration time has elapsed. - View Dependent Claims (13, 14, 15, 16, 17)
