CRJT: Channel Reservation Based Joint Transmission MAC Protocol for the Next Generation WLAN
In the past few decades, the rapid development of wireless local area networks (WLANs) provides great convenience to human lives. However, as the number of users and the complexity of deployment scenarios have increase, the next-generation WLANs face the unprecedented challenge of quality of service (QoS) and quality of experience (QoE) of cell-edge users. In response to this challenge, access point (AP) cooperation is supposed to be a promising solution. In this study, we propose a joint transmission medium access control (MAC) protocol based on channel reservation (CRJT). This protocol can make full use of the wireless channels to complete channel reservations and support joint transmissions effectively between APs. The simulation results show that this protocol provides a robust communication guarantee for edge users.
