Foreword This Technical

16、 Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS). Introduction The present document provides the results of a feasibility study carried out under the ETSI TC on reconfigurable radio systems (RRS). The target of the study was to investigate the need for st

17、andardization within the cellular radio base station to address the requirements resulting from on-situ reconfiguration of future RBS. The study addresses current radio base station architectures, the possibilities provided by software radio architectures and the requirements of future RBS. The stud

18、y considers also the impact of re-configurability on the total life cycle energy consumption and the environmental impact of radio base stations. ETSI ETSI TR 102 681 V1.1.1 (2009-06) 51 Scope The scope of the present document is to investigate and assess possible architectures, related qualities an

19、d corresponding costs of reconfigurable radio base stations (RBS). It covers public radio systems working on licensed bands (including GSM, WCDMA, LTE, WiMax and similar). The present document will include expected future technology and cost developments of these architectures. Definition of key pos

20、sible requirements for SDR applications in RBS, the impact on RBS architecture, network management and equipment certification. It covers reconfigurable RBS on a generic level independent of power classes defined in 3GPP. 2 References References are either specific (identified by date of publication

In clause 4.1 we list general requirements based on different use cases. In clause 4.2 different requirement

40、s based on telecom operator needs and telecom infrastructure equipment manufacturers are listed. 4.1 Re-configurability requirements from use cases 4.1.1 Generic requirements for reconfigurable RBS Transition from one standard to a new (example GSM= WCDMA, WCDMA=LTE, etc.). Multi-standard use, frequ

41、ency re-farming. Spectrum trading. Secondary spectrum usage. Dynamic capacity optimization depending on load (energy saving). Network planning and adaptation, antenna tuning. ETSI ETSI TR 102 681 V1.1.1 (2009-06) 8 Backhaul reconfiguration for flat architecture. These use cases above require the re-

42、configurability of: a) Modulation and BW. b) Frequency allocation (existing bands and future bands, cognitive radio). c) Dynamic spectrum allocation. d) Multi-standard operation. e) Power levels, capacity, efficiency. f) FDD/TDD operation change. g) Network architecture modifications. 4.1.2 Potentia

43、l additional requirements for Femto/home-RBS It is expected that there will be a future market for reconfigurable Mobile Devices that offer the possibility to either operate as a standard Mobile Device entity providing voice/data service access to end-users and/or as a Femto-Base-Station (Femto-BS).

44、 In order to enable an efficient implementation, such “Dual Mode“ devices require the following: The Femto-BS mode of the corresponding “Dual Mode“ device should build on a standard architecture typically applied for Reconfigurable Mobile Devices, for example such as it is defined in TR 102 680 i.4.

45、 Suitable extensions to such available architectures need to be defined. The corresponding device is expected to build on reconfigurable hardware, typically exploiting SDR principles. 4.2 Stakeholder requirements The following requirements are collected from the needs of current stakeholders. The re

46、quirements are separated according to the different stakeholders. A requirement is mentioned in multiple sections if it applies for several stake holders. 4.2.1 Operator requirements The development of different systems which coexist temporally and geographically requires to manage at the same time

47、and in the same area, two or more systems in order to adapt the network to the characteristics of the traffic and optimize the resource usage. Typically, said problem rises for an operator who has already an installed network and wants to add a new network related to a new generation system (e.g. to

48、 add an LTE network to a 2G-3G network already deployed). Moreover, the operator wants to be able to manage dynamically the hardware resources dedicated to the existing system and to the new generation system, according to the traffic variation that insists on the cells of a certain area. Considerin

49、g a cell set in a certain area, it is possible that the traffic of different services on a specified system (or different systems), changes from one area to the other according to the day period. Moreover it could happen that some cells may be congested (high call blocking percentages) in some particular area while surrounding cells are less loaded or characterized by low blocking percentages. In addition, in case of deployment of two or more RATs in the area, the tr
