Efficiency Analysis of Decoupled Downlink and Uplink Access in Heterogeneous Networks
This paper analyzes two-tier heterogeneous cellular network with decoupled downlink and uplink access. The basic performance benefits of uplink/downlink decoupling have been recently introduced. Here we provide a more elaborate treatment of the decoupling mechanism by analyzing spectral and energy efficiency of the system, as the joint improvement of these two features is crucial for the upcomi...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولDecoupled Uplink and Downlink Access in Heterogeneous Networks
Data centric UEs are currently not only demanding more capacity from wireless networks, but also service oriented Quality of Service (QoS) and comparable Quality of Experience (QoE) in both Downlink (DL) and Uplink (UL). With the introduction of internet of things, machine to machine communications, cloud services and the widely-used social media, UEs and devices in general are increasingly mor...
متن کاملUplink Spectral Efficiency Analysis of Decoupled Access in Multiuser MIMO Communications
In a heterogeneous network consisting of macro base stations (MBSs) and small base stations (SBSs), the traditional cell association policy, i.e., coupled access (CA), is far from optimal, due to the significant difference between the coverage and transmit powers of MBSs and SBSs. Hence, users may choose to associate with different types of BSs in downlink (DL) and uplink (UL), i.e., decoupled ...
متن کاملLoad & backhaul aware decoupled downlink/uplink access in 5G systems
Until the 4 Generation (4G) cellular 3GPP systems, a user equipment’s (UE) cell association has been based on the downlink received power from the strongest base station. Recent work has shown that – with an increasing degree of heterogeneity in emerging 5G systems – such an approach is dramatically suboptimal, advocating for an independent association of the downlink and uplink where the downl...
