Abstract:
A transmit apparatus and a method of the transmit apparatus in a wireless communication system supporting ranging capability are provided. The transmit apparatus and the method comprise: identifying whether a medium access control (MAC) common part sublayer (CPS) data request (MCPS-DATA.request) primitive received from a higher layer of the transmit apparatus includes a ranging configuration information element (IE) or a ranging IE; transmitting, to a receive apparatus, a ranging control message (RCM) in response to the MCPS-DATA.request primitive including the ranging configuration IE; transmitting, to the receive apparatus, a ranging initiation message (RIM) in response to the MCPS-DATA.request primitive including the ranging IE; receiving, from the receive apparatus, MAC data including a ranging message non-receipt information element (RMNR IE) that indicates a reception failure of the RIM; and identifying the RMNR IE via an MCPS-DATA.indication primitive.
