Decoupled 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 کاملEfficiency 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...
متن کاملCapacity Analysis of Decoupled Downlink and Uplink Access in 5G Heterogeneous Systems
Our traditional notion of a cell is changing dramatically given the increasing degree of heterogeneity in 4G and emerging 5G systems. Rather than belonging to a specific cell, a device would choose the most suitable connection from the plethora of connections available. In such a setting, given the transmission powers differ significantly between downlink (DL) and uplink (UL), a wireless device...
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...
متن کاملDynamic Joint Uplink and Downlink Optimization for Uplink and Downlink Decoupling-Enabled 5G Heterogeneous Networks
The concept of user-centric and personalized service in the fifth generation (5G) mobile networks encourages technical solutions such as dynamic asymmetric uplink/downlink resource allocation and elastic association of cells to users with decoupled uplink and downlink (DeUD) access. In this paper we develop a joint uplink and downlink optimization algorithm for DeUD-enabled wireless networks fo...
