Having been making effort for nearly two years and integrating the achievement of 06 White Pager, FuTURE FORUM has completed the fundamental contents in the latest version of the technical white paper which involves the contributions from 35 members that have been fully discussed into certain consensus on eight working group meeting during the two years. The first version of the white paper will be revised and improved according to the assessment and suggestions of the distinguished experts before being submitted to the relative governmental departments as the references for decision-making. Meanwhile, FuTURE FORUM will continue to carry out international communication activities to introduce and promote the achievements made by the Forum.
Abstract of the white paper composed by each working group is as followed:
The first part of this white paper puts the end-users at the center of its discussion and provides guidance and collects end-user requirements which the future mobile communication system should meet in the coming 5~10 years. The research methodology is totally End-user oriented and the analyzed user groups are mainly China specific. Then it mainly describes the system requirement of the future communication system. The focus is only on system requirement with impact on the development of a new radio interface concept and design. Based on requirements for supported services, performance requirements are formulated. System capabilities, including mobility support, peer-to-peer communications, and QoS are considered as well as terminal requirements. This paper also provides further work in the translation process from user-centric requirements to technical assessment criteria suited for evaluations.
The second part of the white paper first made the minute division to the mobile communication requirements including social, user, operation,terminal and platform requirements, and simultaneously research on the service platform and operation mode. Eight typical services and applications are cited in this part, such as E-invoice system based on homogeneous networks, mobile yellow pages, P2P data share service and Real World Live View System with detailed description of the requirements, definitions, structures and procedures and gives a stressed discussion on some relative problems such as the actualization and security.
The third part of white paper is mainly focusing on the IMT-Advanced spectrum studies associated with the predicable demands and requirements, the primary radio propagation measurement results, the characteristic analyses of IMT-Advanced candidate bands, and spectrum efficiency enhancement by the novel spectrum utilization technologies. The following viewpoints have been addressed this year during the study: The measurement results of the path-loss model at 3.5GHz in the two metropolitan cities (Beijing and Shanghai) in China provide a good basis of radio propagation study. The primary explorations in spectrum utilization aspect have showed many interesting areas that could be further studied to define the requirements for the future techniques, such as possible deployment in segmented bands，scalable channel bandwidth，capability to share the spectrum with existing primary services，asymmetric spectrum utilization,variable duplex flexibility and so on. As a starting point, three types of the spectrum utilization techniques were illustrated, namely, Spectrum sharing method, Coexistence methods between the different systems and Dynamic spectrum management method.
The fourth part of white paper collects below content: overview of the TDD frame structure of China 863 FuTURE Project, proposal of new system called as DFT-S-GMC; lots of research and proposals for MIMO technique including improved precoding vector selection, simplified precoding method for TDD MIMO, etc.;New proposals to relay for radio system including short cut route scheme, power control scheme and cooperative coding scheme; proposals for conventional technologies like HARQ, V-blast, Link model, antenna positioning and base band remote, etc....
Radio Resource management white paper including following topics: Flexible Spectrum Usage, relay based RRM, Scheduling, Handover and mobility management, Interference control for multi-cells. Most of the interest in WG5 has lain on Relay, together with MIMO and OFDM, future communication system are facing more challenge for RRM. For relay systems,this paper raised these schemes: Inter-Relay interference, Cooperative Relay, Power Allocation, Joint Node Selection and Detection, Relay Selection, Group based random access, directional antenna. There are other topics like Flexible spectrum usage,Mobility management…studied in WG5, which are excellent work done as well.
Network Architecture white paper includes 5 independent parts:Distributed Radio,Network Adaptation to Service Convergence, Network Convergence of Broadcast and Mobile, Ad Hoc in Next Generation Network,System Architecture of End-to-End Reconfigurable (E2R) Networks.Distributed Radio Network is one of the candidate architectures with flat, high-efficient,reliable requirements and worked with different spectrum resources.Service convergence across multiple networks may serve end-user well with more convenience, provided by the integration of related information from corresponding networks. Part 3 outlines the trend of network convergence of broadcast and mobile. Part 4 proposes, next generation networking ought to integrate the Ad Hoc technology into the network construction with the arduous target. Part 5 introduces System Architecture of End-to-End Reconfigurable (E2R) Networks. End-to-End Reconfigurability (E2R) is a major contributor towards transforming the wireless communications into one global infrastructure.
