9、 IMT-Advanced (Question ITU-R 229-3/5) (2015-2017) Scope This Recommendation provides the generic unwanted emission characteristics of base stations using the terrestrial radio interfaces of IMT-Advanced. The information about unwanted emissions included in this Recommendation could also be used as
10、guidance by Administrations for cases not specifically covered herein. Implementation of characteristics of base stations using the terrestrial radio interfaces of IMT-Advanced in any of the bands included in this Recommendation is subject to compliance with the Radio Regulations. Keywords IMT-Advan
11、ced, emission characteristics, out-of-band, unwanted, base station The ITU Radiocommunication Assembly, considering a) that unwanted emissions consist of both spurious and out-of-band (OoB) emissions according to No. 1.146 of the Radio Regulations (RR) and that spurious and OoB emissions are defined
12、 in RR Nos 1.145 and 1.144, respectively; b) that limitation of the maximum permitted levels of unwanted emissions of IMT-Advanced base stations (BS) is necessary to protect other radio systems and services from interference and to enable coexistence between different technologies; c) that too strin
13、gent limits may lead to an increase in complexity of IMT-Advanced BS; d) that every effort should be made to keep limits for unwanted emissions at the lowest possible values taking account of economic factors and technological limitations; e) that Recommendation ITU-R SM.329 relates to the effects,
14、measurements and limits to be applied to spurious domain emissions; f) that the same spurious emission limits apply equally to all radio interfaces; g) that Recommendation ITU-R SM.1541 relating to OoB emission specifies generic limits in the OoB domain which generally constitute the least restricti
15、ve OoB emission limits and encourages the development of more specific limits for each system; h) that the levels of spurious emissions of IMT-Advanced BS shall comply with the limits specified in RR Appendix 3; i) that the harmonization of unwanted emission limits will facilitate global use and acc
16、ess to a global market; however national/regional variations in unwanted emission limits may exist; j) that unwanted emission limits are dependent on the transmitter emission characteristics, ITU spurious emission limits and national standards and regulations in addition to depending on services ope
17、rating in other bands; k) that the technology used by a system and its conformance with the recommended specifications and standards in Recommendation ITU-R M.2012 defines that system as IMT-Advanced regardless of the frequency band of operation, 2 Rec. ITU-R M.2070-1 noting a) the work carried out
18、by standardization bodies to define limits to protect other radio systems and services from interference and to enable coexistence between different technologies; b) that IMT-Advanced base stations must comply with local, regional, and international regulations for out-of-band and spurious emissions
19、 relevant to their operations, wherever such regulations apply; c) that the notes and annexes of this Recommendation being based on the ongoing work in standardization bodies in order to reflect the wide applicability of IMT-Advanced technologies and to maintain consistency with the technology speci
20、fications, may contain material which reflects information related to the technology applications in bands other than those identified for IMT, noting further 1 that there are ongoing studies within ITU-R regarding the protection of other services from unwanted emissions of IMT-Advanced stations to
21、address further cases of compatibility, recommends 1 that the unwanted emission characteristics of IMT-Advanced base stations should be based on the limits contained in the technology specified in Annexes 1 and 2 which correspond to the terrestrial radio interface specifications referenced in recomm
22、ends 1 of Recommendation ITU-R M.2012; 2 that the unwanted emission characteristics of IMT-Advanced base stations in Annexes 1 and 2 should apply in Regions and countries in which corresponding bands are identified for IMT in the Radio Regulations*.

23、ed2 Annex 1 LTE-Advanced The present Annex includes unwanted emission requirements from E-UTRA carriers for E-UTRA and multi standard radio (MSR) base stations. An E-UTRA base station is characterized by the ability of its receiver and transmitter to process only E-UTRA carriers. * In other cases th
24、e unwanted emission characteristics of IMT-Advanced base stations in Annexes 1 and 2 are provided for information. Administrations may choose to apply the unwanted characteristics in Annexes 1 and 2 for the bands not identified for IMT at their national level. 1 Developed by 3GPP as LTE Release 10 a
