Device-To-Device (D2D) Communication Under LTE-Advanced Networks

The key attributes envisioned for LTE-Advanced pertaining to 5G Networks are ubiquitous presence, device convergence, massive machine connectivity, ultrahigh throughput and moderated carbon footprint of the network and the user equipment actuated by offloading cellular data traffic and by enabling device to device communication. The present method of mobility management and addressing as the authors have foreseen in LTE Advanced can solve some issues of cellular traffic backhaul towards the access and core network by actuating a local breakout and enabling communication directly between devices. But most of the approaches look forward towards an enhancement in the radio resource allocation process and prone to interference. Besides, most of these proposals delve in Device to Device (D2D) mode initiation from the device end, but no research has so far addressed the concept of a network initiated D2D process, which can optimise the channel utilisation and network operations further. In their attempt to knot these loose ends together, the auhtors furnish the concept of WISDOM (Wireless Innovative System for Dynamic Operating Mega communications) (Badoi Cornelia-I., Prasad N., Croitoru V., Prasad R., 2011) (Prasad R., June 2013) (Prasad R.,December 2013) and SMNAT (Sanyal, R., Cianca, E. and Prasad,R.,2012a) () () () (. Further, the authors explore how SMNAT (Smart Mobile Network Access Topology) can engage with WISDOM in cooperative communication to actuate D2D communication initiated by the device or the network. WISDOM is an architectural concept for 5G Networks based on cognitive radio approach. The cognition, sustained by adaptation techniques, is a way to provide communication, convergence, connectivity, co-operation, and content, anytime and anywhere. Though D2D communication using a dedicated spectrum in multi cell environment is possible through advanced network coding or by use of fractional frequency reuse, but physical proximity of the 2 devices is still a key requisite. In this paper the authors will discuss SMNAT which employs physical layer addressing to enable D2D communication agnostic to the spatial coordinates of the devices.

Didalam sebuah sistem telekomunikasi selular yang konvensional, perangkat-perangkat pengguna(UE) adalah tidak dimungkinkan untuk saling berkomunikasi secara langsung (directcommunication) didalam bandwidth selular yang berlisensi. Semua komunikasi yang berlangsungharus melalui eNB atau base station (BS) sebagai jaringan inti (core network). Suatu kebutuhanuntuk meningkatkan kapasitas jaringan dalam memenuhi permintaan-permintaan yang terusberkembang dari para pengguna telah membawa pada evolusi jaringan-jaringan telekomunikasiselular dari generasi pertama (1G) hingga generasi ke lima (5G). Sebuah metode baru D2DCommunication diperkenalkan dalam standar telekomunikasi selular konvensional terbaru LTE.Metode D2D Communication ini diantaranya diterapkan pada sistem radio keselamatan publik(public safety radio system). Dan saat ini, sistem radio keselamatan publik yang berbasis LTEtersebut sedang dipertimbangkan untuk digunakan karena dapat mengurangi biaya-biayaoperasional dan pembangunan jaringan. Fungsi-fungsi komunikasi secara langsung dengan membypass eNB (tanpa melibatkan eNB) telah diperkenalkan didalam standar spesifikasi 3GPP Release12 LTE-Advanced untuk sistem radio keselamatan publik sehingga komunikasi-komunikasi dapatdisediakan bahkan jika sebuah eNB mengalami down (failure atau kerusakan) karena adanya suatubencana dengan skala yang besar, gempa bumi atau tsunami dsb. Fungsi-fungsi Device Discoveryyang memungkinkan D2D komersial juga diperkenalkan pada release 12 tersebut.

Device-to-Device (D2D) communication allows user devices in proximity to directly communicate with each other through reusing resources in cellular communication system. D2D improves the system capacity while it also raises some challenges on interference. This paper adopts reconfigurable antenna in D2D communication generating directional signal transmission between D2D pairs which mitigates the interference to other users. The simulations show that such scheme improve the system capacity compared to the traditional one.
