M-TDLS: Enhancement of VR Quality of Service Using Coordinated OFDMA and Direct Links

The popularity of interactive virtual reality (VR) applications has been significantly growing in recent years, and VR headsets are becoming more and more commonly available. Wireless communication technologies, such as Wi-Fi, are often used to connect the VR headset to the network. The interactive nature of VR applications imposes strict constraints on the delay and reliability of data transmission, which is difficult to achieve with current medium access methods. This paper proposes a new M-TDLS medium access method that allows a Wi-Fi access point to allocate a secondary channel for direct transmissions of VR data. With simulation, it has been shown that the M-TDLS method improves the reliability of VR traffic transmission without degrading the quality of service of background traffic.
