9、2000 (Question ITU-R 229-2/5) (2002-2003-2007-2009-2012-2014) Scope This Recommendation provides the generic unwanted emission characteristics of mobile stations using the terrestrial radio interfaces of IMT-2000, suitable for establishing the technical basis for global circulation of IMT-2000 termi
10、nals. Implementation of characteristics of mobile stations using the terrestrial radio interfaces of IMT-2000 in any of the bands included in this Recommendation is subject to compliance with the Radio Regulations. The ITU Radiocommunication Assembly, considering a) that unwanted emissions consist o
11、f 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 in RR Nos. 1.145 and 1.144, respectively; b) that limitation of the maximum permitted levels of unwanted emissions of IMT-2000 mobile stations (MSs) is
12、 necessary to protect other radio systems and services from interference and to enable coexistence between different technologies; c) that too stringent limits may lead to an increase in size or in complexity of IMT-2000 radio equipment; d) that every effort should be made to keep limits for unwante
13、d 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, measurements and limits to be applied to spurious domain emissions; f) that the same spurious emission limits apply equally to MSs o
14、f 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 restrictive OoB emission limits and encourages the development of more specific limits for each system; h) that the levels of spurious
15、 emissions of IMT-2000 terminals shall comply with the limits specified in RR Appendix 3; i) that Recommendation ITU-R M.1579 establishes the technical basis for global circulation of IMT-2000 MSs; j) that one of the basic requirements of global circulation is that the MS does not cause harmful inte
16、rference in any country where it is taken; k) that the harmonization of unwanted emission limits will facilitate global use and access to a global market; *This Recommendation should be brought to the attention of Radiocommunication Study Group 1. 2 Rec. ITU-R M.1581-5 l) that unwanted emission limi
17、ts are dependent on the transmitter emission characteristics in addition to depending on services operating in other bands; m) that the technology used by a system and its conformance with the recommended specifications and standards in Recommendation ITU-R M.1457 defines that system as IMT-2000 reg
18、ardless of the frequency band of operation; n) that harmonized frequency arrangements for the bands identified for IMT are addressed in Recommendation ITU-R M.1036, which also indicates that “some administrations may deploy IMT-2000 systems in bands other than those identified in the RR”, noting a)
19、the work carried out 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-2000 mobile stations must comply with local, regional, and international regulations for out-of-band and
20、 spurious emissions 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-2000 technologies and to maintain consistency with the t
21、echnology specifications, may contain material which reflects information related to the technology applications in bands other than those identified for IMT, recommends that the unwanted emission characteristics of IMT-2000 MSs should be based on the limits contained in the technology specific Anne
22、xes 1 to 6 which correspond to the radio interface specifications described in 5.1 to 5.6 of Recommendation ITU-R M.1457. NOTE 1 Except the cases stated in Notes 2, 3, 4 and 5, the unwanted emission limits are only defined for mobile stations operating according to the following arrangement: frequen
23、cy division duplex (FDD) uplink in the band 1 920-1 980 MHz, FDD downlink in the band 2 110-2 170 MHz and time division duplex (TDD) in the bands 1 885-1 980 and 2 010-2 025 MHz. Future versions of this Recommendation will include limits applicable to other frequency bands. Subject to further study,
24、 it is anticipated that such limits would be similar to those already contained in this Recommendation. NOTE 2 The unwanted emission limits defined in Annex 1 are for MS operating at least one of the following arrangements: Frequency division duplex (FDD) uplink in the band 1 920-1 980 MHz, FDD down
