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.
