Foreword
13、 This Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS). Introduction The present document addresses, in particular, the studies carried out by ETSI TC-RRS related to the study reports published by the working group WG1, WG2, WG3 and WG4. For exam
14、ple, the study results provided by ETSI TC-RRS working groups have been considered for items of potential relevance to regulation authorities. The present document provides a recommendation to ETSI TC-RRS working groups. It is outlined which technical proposal of the working groups may require furth
15、er regulatory actions in order to be deployed in the market. As a European Standardization Organisation, ETSI receives mandate from the European Commission to develop Harmonised Standards that have a regulatory status as they can be referenced to by manufacturers to ensure that their products comply
16、 with the essential requirements of the R potentially CR enablers and functionalities need to be indentified which are beyond the scope of the present document, which is limited to those addressed so far, in particular in ETSI RRS technical reports i.1 to i.6.

18、ipment Architecture WG3: Functional Architecture and Cognitive Pilot Channel (in Cognitive Radio Network Management) WG4: RRS Public Safety As a whole these studies have covered radio system technologies more generally known as Software Defined Radio and Cognitive Radio. The present document also ad
19、dresses the outcome of previous work such as that carried out by TCAM as a result of the Report drafted by its ad-hoc group on Software Defined Radios i.7, in particular during TCAM meetings 17, 18 and 19. 2 References References are either specific (identified by date of publication and/or edition

34、e Committee 4 Regulatory issues related to SDR and CR feasibility studies This clause summarizes potential regulatory issues of relevance in the study reports of all TC-RRS working groups. It also includes conclusions reached by previous work, such as that carried out by TCAM (see clauses 4.1 and 4.
35、4). 4.1 Potential regulatory issues in TR 102 680 SDR Mobile Device Market Model Responsibility Issues: in the case that a device does not operate within the regulatory framework, the regulators typically request that the responsibility are within one single entity which needs to be easily identifia
36、ble. TCAM (Telecommunications Conformity Assessment and Market Surveillance Committee) studies proposed a definition for two market models - horizontal and vertical markets i.7: - Vertical Markets: all hardware and SDR software which is relevant for the declaration of conformity with the essential r
37、equirements for the intended use during the whole life cycle are controlled by one entity; - Horizontal market: independent companies placing hardware and SDR software (3rd party SW providers, etc.) separately on the market which, when used together, are subject to declaration of conformity with the
38、 essential requirements for the intended use of the equipment. Responsibility issues can often be avoided or minimized by applying the Vertical Markets model. In case of the Horizontal market model, it is important to satisfy regulatory requirements. Frequency agility The SDR radio applications will
39、 operate on multiple frequency bands (e.g. from 400 MHz to 10 GHz) and use multiple bandwidths (e.g. from 200 KHz to 500 MHz): - Depending on the usage of SDR technology, a regulatory impact may or may not be expected. For example, if SDR is applied for initial implementation purposes only and no fu
40、rther spectrum usage flexibility is introduced, then no regulatory impact is expected; however, in case that the spectrum usage flexibility is increased, there would be a regulatory impact. Multiradio configuration capability As stated in i.1, SDR equipment is expected to offer multiradio configurat
41、ion capability: “Multiradio configuration capability: SDR equipment in mobile device is expected to install, load and activate a radio application while running a set of radio systems already.“: - It is not expected that the multiradio configuration capability in general will lead to regulatory issu
42、es at this stage. As stated in i.1, SDR equipment is expected to offer multiradio operation capability: “Multiradio operation capability: SDR equipment in mobile device is expected to execute number of radio systems simultaneously“: - It is expected that the multiradio operation capability may poten
43、tially lead to issues for ensuring the satisfaction of test and validation requirements imposed by regulators. ETSI ETSI TR 102 803 V1.1.1 (2010-03) 8- Example of an issue as it may typically arise if a device has multiradio operation capability: As an example, it is assumed that computational resou
44、rces within a Mobile Device are not sufficient for full simultaneous operation of multiple RATs; in order to address this problem, for example, a GSM transmitter may drop some speech frames in order to reduce the computation requirements that are then used for the simultaneous operation of other RAT
45、s. In such a scenario, various issues and questions may come up such as for example: is there currently a regulatory requirement that all speech frames need to be transmitted ? This is a new problem not considered by radio standards so far. If such a device behaviour could occur, the corresponding r
46、egulatory implications need to be investigated. As stated in i.1, SDR equipment is expected to offer “Compile-time and run-time functions of Radio Computer“: - Compile functions are assumed to be done by the manufacturer off-line and not by each device. Consequently, no regulatory issues are expecte
47、d. - Linkage/Insertation of new software into a device taking its current configuration into account (i.e. memory addresses for RAT code may depend on code already available on the device). Consequently, no regulatory issues are expected. - Depending on the execution environment, there may be potent
48、ial issues for the specific case of “interpreted code“ (similar to JAVA requiring a JAVA runtime environment or any other interpreter). In such a case it is unclear how the platform is reacting to execution errors and hence the compliance to the regulatory framework needs to be ensured. - In general
49、, the execution environment ensures that the regulatory framework requirements are met. Item of potential regulatory relevance: Functional architecture of SDR Equipment As stated in i.1, SDR equipment is expected to introduce a novel Functional Architecture. An abstract architecture is not expected to have regulatory implications. 4.2 Potential regulatory issues in TR 102 683 Item of potential regulatory relevance: In-band CPC Following the definitions in i.4, no regulatory issues are expected for the in-band
