Foreword This Technical Specification (TS) has been produced by ETSI Technical Committ

26、ee Satellite Earth Stations and Systems (SES). The present document is specifying the Satellite Radio Interface referenced as SRI Family G at ITU-R, in the frame of the modification of ITU-R Recommendation M.1457 10. This modification has been approved at SG8 meeting in November 2005. The present do

27、cument is part 2, sub-part 1 of a multi-part deliverable covering Satellite Earth Stations 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 c

28、oding“; Sub-part 1: “G-family (S-UMTS-G 25.212)“; Sub-part 2: “A-family (S-UMTS-A 25.212)“; Part 3: “Spreading and modulation“; Part 4: “Physical layer procedures“; Part 5: “UE Radio Transmission and Reception“; Part 6: “Ground stations and space segment radio transmission and reception“. Introducti

29、on S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication 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 S

30、ervices (MSS) utilizing either low (LEO) or medium (MEO) earth orbiting, or geostationary (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 differe

31、ntiate the Terrestrial UMTS component. ETSI ETSI TS 101 851-2-1 V2.1.1 (2008-01) 6 Due to the differences between terrestrial and satellite channel characteristics, some modifications to the terrestrial UMTS (T-UMTS) standards are necessary. Some specifications are directly applicable, whereas other

32、s are applicable with modifications. Similarly, some T-UMTS specifications do not apply, whilst some S-UMTS specifications have no corresponding T-UMTS specification. Since S-UMTS is derived from T-UMTS, the organization of the S-UMTS specifications closely follows the original 3rdGeneration Partner

33、ship Project (3GPP) structure. The S-UMTS numbers have been designed to correspond to the 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

34、, B, C, etc.) denotes the family of S-UMTS specifications. An S-UMTS system is defined 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 precedenc

35、e rule applies to any references in the corresponding 3GPP specifications. NOTE 2: Any 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.

36、 If an S-UMTS specification does not exist, the corresponding 3GPP specification may or may not apply. The exact applicability of the complete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 101 851-2-1 V2.1.1 (2008-01) 7 1 Scope The present document describes the charact

37、eristics of the Layer 1 multiplexing and channel coding used for family G of the satellite component of UMTS (S-UMTS-G). It is based on the FDD mode of UTRA defined by TS 125 211 6, TS 125 212 7, TS 125 213 8 and TS 125 214 9 and adapted for operation over satellite transponders. 2 References Refere
