Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and S

This modification has been approved at SG8 meeting in November 2005. The contents of the present document are subject
23、 to continuing work within TC-SES and may change following formal TC-SES approval. Should TC-SES modify the contents of the present document it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 1.m.n Where: the third dig

Introduction S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication Syste
27、m. 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 geostationary (G
28、EO) 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. ETSI ETSI TS 101 851-4 V1.2.1 (2006-01) 6 Due to the
29、differences between terrestrial and satellite 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, whils
30、t 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 Partnership Project (3GPP) structure. The S-UMTS numbers have been designed to correspond to the 3GPP
31、 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, ) denotes the family of S-UMTS specifications. An S-UMTS system is defined by the comb
32、ination 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 references
33、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 may not ap
34、ply. The exact applicability of the complete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 101 851-4 V1.2.1 (2006-01) 7 1 Scope The present document specifies the characteristics of the physical layer procedures used for family G of the satellite component of UMTS (S-UM
35、TS-G). It is based on the FDD mode of UTRA defined by TS 125 211 5, TS 125 212 6, TS 125 213 7, TS 125 215 8, TS 125 214 9, TS 125 331 10 and TS 125 433 11 and adapted for operation over satellite transponders. 2 References The following documents contain provisions which, through reference in this
