  • Patent number: 10609711
    Abstract: The predicted explosive growth in the number of wireless devices and mobile applications utilizing wireless networks makes it time for engineers to face the high network densification challenge where massive numbers of terminal devices (TDs) coexist and require both high-rate and low-latency wireless data transmissions. We describe a multiple access point (AP) Time-Reversal Division Multiple Access (TRDMA) downlink system that utilizes the natural spatial and temporal focusing properties of Time Reversal (TR) based communications, where the interference to unintended receivers is automatically at least partially mitigated. As a result, in some implementations, the TRDMA system can achieve full or nearly-full spectrum reuse without any coordination among APs. 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.
