Benefiting from the usage of high-frequency band, utilizing part large available bandwidth for wireless backhauling is feasible without considerable performance sacrifice. In this context, integrated access and backhaul (IAB) was proposed by 3GPP to reduce fiber optics deployment cost 5G beyond networks. paper, we first give a brief introduction IAB based on release. After that, survey existing...

We propose a modification of the IEEE 802.16e hard handover (HHO) procedure, which significantly reduces the handover latency constraint of the original HHO procedure in IEEE 802.16e networks. It allows a better handling of the delay-sensitive traffic by avoiding unnecessary time-consuming scanning and synchronization activity as well as simplifies the network re-entry procedure. With the help ...

We consider wireless backhauling for a scenario where two small-cell base stations (SC-BSs) employ the same time and frequency resources for offloading their data to a common macro-cell base station (MC-BS). The two SC-BSs allocate a part of the shared resource to exchange data in order to be able to cooperate to boost the backhaul capacity. For this scenario, we develop the optimal transmissio...

Integrating terrestrial networks with burgeoning high-altitude platform stations (HAPSs) will be a disruptive challenge for beyond-5G systems provisioning large-scale three-dimensional connectivity. Here, we study the problem of forwarding packets between terminals and backhaul through multi-HAPS relaying. Considering limited wireless backhaul, which is practical constraint HAPS relaying, dual-...

The use of multiple source nodes with wireless backhaul is considered for secrecy enhancement through node selection in future networks. ergodic rate (ESR) optimal the presence eavesdroppers over independent non-identically distributed (INID) Rayleigh fading channels evaluated closed-form. At high signal-to-noise ratio (SNR), ESR expressed as a simple weighted summation where each term relates ...

Wireless communications can facilitate the deployment of novel industrial applications to improve productivity or health and safety conditions. Health and safety applications require mobile solutions capable to operate under harsh propagation conditions at low cost and energy consumption. This paper presents the results of an extensive measurement campaign that demonstrate the feasibility to de...
