Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is specifying the S

20、atellite Radio Interface referenced as SRI Family G at ITU-R, in the frame of the modification of ITU-R Recommendation M.1457 13. This modification has been approved at SG8 meeting in November 2005. The present document is part 4, sub-part 1 of a multi-part deliverable covering Satellite Earth Stati

21、ons and Systems (SES); Satellite Component of UMTS/IMT-2000; G-family, as identified below: Part 1: “Physical channels and mapping of transport channels into physical channels“; Part 2: “Multiplexing and channel coding“; Part 3: “Spreading and modulation“; Part 4: “Physical layer procedures“; Sub-pa

22、rt 1: “G-family (S-UMTS-G 25.214)“; Sub-part 2: “A-family (S-UMTS-A 25.214)“; Part 5: “UE Radio Transmission and Reception“; Part 6: “Ground stations and space segment radio transmission and reception“. Introduction S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication

23、System. S-UMTS systems will complement the terrestrial UMTS (T-UMTS) and inter-work with other IMT-2000 family members through the UMTS core network. S-UMTS will be used to deliver 3rdgeneration Mobile Satellite Services (MSS) utilizing either low (LEO) or medium (MEO) earth orbiting, or geostationa

24、ry (GEO) satellite(s). S-UMTS systems are based on terrestrial 3GPP specifications and will support access to GSM/UMTS core networks. NOTE 1: The term T-UMTS will be used in the present document to further differentiate the Terrestrial UMTS component. Due to the differences between terrestrial and s

25、atellite channel characteristics, some modifications to the terrestrial UMTS (T-UMTS) standards are necessary. Some specifications are directly applicable, whereas others are applicable with modifications. Similarly, some T-UMTS specifications do not apply, whilst some S-UMTS specifications have no

26、corresponding T-UMTS specification. ETSI ETSI TS 101 851-4-1 V2.1.1 (2008-01) 6 Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closely follows the original 3rdGeneration Partnership Project (3GPP) structure. The S-UMTS numbers have been designed to correspond to t

27、he 3GPP terrestrial UMTS numbering system. All S-UMTS specifications are allocated a unique S-UMTS number as follows: S-UMTS-n xx.yyy Where: The numbers xx and yyy correspond to the 3GPP-numbering scheme. n (n = A, B, C, etc.) denotes the family of S-UMTS specifications. An S-UMTS system is defined

28、by the combination of a family of S-UMTS specifications and 3GPP specifications, as follows: If an S-UMTS specification exists it takes precedence over the corresponding 3GPP specification (if any). This precedence rule applies to any references in the corresponding 3GPP specifications. NOTE 2: Any

29、references to 3GPP specifications within the S-UMTS specifications are not subject to this precedence rule. EXAMPLE: An S-UMTS specification may contain specific references to the corresponding 3GPP specification. If an S-UMTS specification does not exist, the corresponding 3GPP specification may or

30、 may not apply. The exact applicability of the complete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 101 851-4-1 V2.1.1 (2008-01) 7 1 Scope The present document specifies the characteristics of the physical layer procedures used for family G of the satellite component

31、of UMTS (S-UMTS-G). It is based on the FDD mode of UTRA defined by TS 125 211 4, TS 125 212 9, TS 125 213 10, TS 125 215 11, TS 125 214 5, TS 125 331 12 and TS 125 433 6 and adapted for operation over satellite transponders. 2 References References are either specific (identified by date of publicat

32、ion and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future

33、changes of the referenced document for the purposes of the referring document; - for informative references. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.etsi.org/Reference. For online referenced documents, information suff

34、icient to identify and locate the source shall be provided. Preferably, the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the reference should, as far as possible, remain valid for the expected life of the document. The reference shall inclu

35、de the method of access to the referenced document and the full network address, with the same punctuation and use of upper case and lower case letters. NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee their long term validity. 2.1 Normat
