“…Based on current research trends [5] and developments within IEEE 802.11ax HEW [3], several future use cases for 802.11ax can be identified. Figure 1 shows some of the use cases proposed for HEW in 5G-U [7]. These include a high throughput HEW in the form of a gigabit ethernet connection replacement, improved network capacity with multi-user multiple-input and multiple-output (MU-MIMO) transmissions, using HEW as a backhaul for local area networks (LAN), and supporting highly dense scenarios (such as an office building, stadium, train, etc.).…”

“…Since the IEEE 802.11ax HEW amendment is a successor to IEEE 802.11ac very high throughput (VHT), Wi-Fi radio links can effectively replace wired backhaul connectivity, especially for those deployment infrastructures where wired connection deployment is a challenging task [7]. HEW, as a backhaul connection as shown in Figure 1c, is surely the most straightforward application of this concept.…”

The IEEE 802.11ax high-efficiency wireless local area network (HEW) is promising as a foundation for evolving the fifth-generation (5G) radio access network on unlicensed bands (5G-U). 5G-U is a continued effort toward rich ubiquitous communication infrastructures, promising faster and reliable services for the end user. HEW is likely to provide four times higher network efficiency even in highly dense network deployments. However, the current wireless local area network (WLAN) itself faces huge challenge of efficient radio access due to its contention-based nature. WLAN uses a carrier sense multiple access with collision avoidance (CSMA/CA) procedure in medium access control (MAC) protocols, which is based on a binary exponential backoff (BEB) mechanism. Blind increase and decrease of the contention window in BEB limits the performance of WLAN to a limited number of contenders, thus affecting end-user quality of experience. In this paper, we identify future use cases of HEW proposed for 5G-U networks. We use a self-scrutinized channel observation-based scaled backoff (COSB) mechanism to handle the high-density contention challenges. Furthermore, a recursive discrete-time Markov chain model (R-DTMC) is formulated to analyze the performance efficiency of the proposed solution. The analytical and simulation results show that the proposed mechanism can improve user experience in 5G-U networks.

Recently, wireless networks and traffic requirements have been rapidly aggregated in diverse applications in 5G environments. For this reason, researchers have investigated the influences of this growth based on a user's requirements inside these networks. However, the stream of traffic has been considered a crucial role for the user's needs over 5G network. In this paper, gigantic data traffic is considered for enabling dynamic spectrum sharing over 5G networks. Thus, various accessing plans are covered to manage the overall network traffic. Additionally, it proposes a traffic predicting model for a technique of managing traffic when multiple requests are received to decrease delays. It has considered different significances related to a large size of traffic practices. Additionally, this work will guide us to enhance traffic solutions within massive requests over outsized networks. Systematically, it has focused on the traffic flow, starting from the accessing steps until passing on requests to suitable spectrum carriers.

“…However, such approach has a lot of drawbacks, since high amount of RTS and CTS frame exchange occupies airtime (Kosek-Szott et al 2017), this is because these control frames are being transmitted at lowest data rate 6 Mbps which reserves wireless medium for long duration. Therefore, a typical wireless network tries to avoid extensive usage of RTS and CTS frame mechanism and only in cases when frame transmission fails for several times uses RTS and CTS exchange to reserve wireless medium.…”
