V+D Synch ABSTRACT A new programmable radio has been designed by ITT and in a companion paper [IJ we describe new channel-access protocols that are specifically designed for this radio. The protocols described in the companion paper support a network organization in which all the radios are within communication range. In this manuscript we suggest some extensions to the waveform and the channel...

The novel wireless network architecture forces a demanding performance requirement on the radio resource to provide broadband internet access. The Communication industry has been preparing new standards to efficiently transport high speed broadband mobile access in a solitary air interface and network architecture at little cost to operators and end users. Two standards, IEEE 802.16 (WiMAX) and...

In multi access network environments, mobile stations may encounter multiple choices for selecting an access network. Carefully designed access selection schemes can provide not only mobile users with better services but also network operators with better resource utilizations. It is also envisioned that further improvements can be achieved by redistributing mobile stations from one access netw...

Virtual radio access networks (RANs) is the candidate solution for 5G access networks, the concept of virtualised radio resources completing the virtual RAN paradigm. This paper proposes a new analytical model for the management of virtual radio resources in full heterogeneous networks. The estimation of network capacity and data rate allocation are the model’s two main components. Based on the...

© 2014 Yonghoon Choi 953 http://dx.doi.org/10.4218/etrij.14.0113.0843 This paper studies the uplink resource allocation for multiple radio access (MRA) in reconfigurable radio systems, where multiple-input and multiple-output (MIMO) multicarrier-code division multiple access (MCCDMA) and MIMO orthogonal frequency-division multiple access (OFDMA) networks coexist. By assuming multi-radio user eq...

Mobile operators are witnessing a dramatic increase in traffic spurred by a combination of popularity of smartphones, innovative applications and diverse services. As mobile traffic transitions from being voice dominated to video and data dominated, the revenue per byte for the mobile operators is declining at an unhealthy rate. To counter the traffic growth and build cost-effective networks, m...

This paper describes mobility management for the third-generation mobile networks. We focus on the evolution from General Packet Radio Service (GPRS) to Universal Mobile Telecommunication System (UMTS). In this evolution, the radio access network UTRAN has been introduced, and radio-related management is moved from the core network to UTRAN. We elaborate on how this architecture change affects ...

The UTRAN consists of a set of Radio Network Subsystems connected to the Core Network through the Iu. The Iu interface has two flavours: the Iu-CS, connecting to the Circuit-Switched-domain, the Iu-PS when connecting to the Packet-Switched-domain. A Radio Network Subsystem (RNS) consists of a Radio Network Controller and one or more Node Bs. A Node B is connected to the RNC through the Iub inte...
