Abstract: A transmitting device may determine that a first neighbor device is communicating with a second neighbor device based on a signal received from the first device (e.g., a request-to-send (RTS) signal) during a listen-before-talk (LBT) period. The transmitting device may also identify a direction of the second neighbor device (e.g., based on signals received during a previous LBT period), and determine the amount of interference that a directional transmission may cause at the second neighbor device. The determination may be based on whether the transmission direction (i.e., a beam direction of a directional transmission) is in a same direction as the second neighbor device. If the interference level is below a threshold, the transmitting device may perform the transmission despite receiving the signal during the LBT period. If the interference level is above the threshold, the transmitting device may refrain from transmitting.

The performance of the TRDMA system is investigated in both an open access model where an AP is open to all the TDs and a closed access model where an AP is only open to specific TDs.
