Abstract: An electronic device and a method of the electronic device for performing localization in a wireless communication system are provided. The electronic device and method comprise: receiving, from a plurality of anchor nodes, signals for the localization; performing ranging measurements of the signals based on a range and an angle of arrival (AoA) of the signals; determining whether at least one of the plurality of anchor nodes is not detected based on the ranging measurements; determining, based on a determination that the at least one anchor node is not detected based on the ranging measurements, whether at least one other anchor node in the plurality of anchor nodes is located on a line of sight (LOS) from the electronic device, wherein the LOS is determined based on the AoA of the signals; and performing the localization based on the at least one other anchor node.

Abstract: A method and apparatus of a network entity in a wireless communication system supporting ranging capability. The method includes generating a medium access control (MAC) common part sublayer-data request primitive including a ranging enable indicator and a ranging request measurement and control IE (RRMC IE) with a reply-time request. The RRMC IE includes request fields for a reply time, a round-trip measurement, a time-of-flight, an angle of arrival (AOA) azimuth, an AoA elevation, a ranging control information, a reserved bit, an RRMC table length, and an RRMC table. The method further includes transmitting MAC Data including the RRMC IE to another network entity and receiving MAC Data including a ranging reply time instantaneous IE from the other network entity. A local value of a receive ranging counter is identified at the network entity.
