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

20、S). The present document is specifying the Satellite Radio Interface referenced as SRI Family A at ITU-R, in the frame of ITU-R Recommendation M.1457 9. The present document is part 1, sub-part 2 of a multi-part deliverable covering Satellite Earth Stations and Systems (SES); Satellite Component of

21、UMTS/IMT-2000; A-family, as identified below: Part 1: “Physical channels and mapping of transport channels into physical channels“; Sub-part 1: “G-family (S-UMTS-G 25.211)“; Sub-part 2: “A-family (S-UMTS-A 25.211)“; Part 2: “Multiplexing and channel coding“; Part 3: “Spreading and modulation“; Part

22、4: “Physical layer procedures“; 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 System. S-UMTS systems will complement the ter

23、restrial 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 (GEO) satellite(s). S-UMTS systems are base

24、d 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 satellite channel characteristics, some modific

25、ations 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 corresponding T-UMTS specification. ETSI ETSI

26、TS 101 851-1-2 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 the 3GPP terrestrial UMTS numbering system. All

27、 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. A S-UMTS system is defined by the combination of a family of S-UMTS specificat

28、ions 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 to 3GPP specifications within the S-UMTS

29、 specifications are not subject to this precedence rule. For example, an S-UMTS specification may contain specific references to the corresponding 3GPP specification. If a S-UMTS specification does not exist, the corresponding 3GPP specification may or may not apply. The exact applicability of the c

30、omplete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 101 851-1-2 V2.1.1 (2008-01) 7 1 Scope The present document defines the Layer 1 transport channels and physical channels used for family A of the satellite component of UMTS (S-UMTS-A). It is based on the FDD mode of

31、 UTRA defined by TS 125 211 4, TS 125 212 5, TS 125 213 6, TS 125 214 7 and adapted for operation over satellite transponders. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent

32、 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 changes of the referenced document for the purposes of the referring document; - for informative r

33、eferences. 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 sufficient to identify and locate the source shall be provided. Preferably, the primary source of the

34、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 include the method of access to the referenced document and the full network address, with the same pun

46、 4 Services offered to higher layers 4.1 Transport channels Transport channels are services offered by Layer 1 to the higher layers. General concepts about transport channels are described in 8. A transport channel is defined by how and with what characteristics data are transferred over the air int

47、erface. A general classification of transport channels is into two groups: - Dedicated channels, using inherent addressing of UE; - Common channels, using explicit addressing of UE if addressing is needed. 4.1.1 Dedicated transport channels There exists only one type of dedicated transport channel,

48、the Dedicated Channel (DCH). 4.1.1.1 DCH - Dedicated Channel The Dedicated Channel (DCH) is a downlink or uplink transport channel. The DCH is transmitted over the entire cell or over only a part of the cell using e.g. beam-forming antennas. 4.1.2 Common transport channels There are six types of com

49、mon transport channels: BCH, FACH, PCH, RACH, CPCH and DSCH. 4.1.2.1 BCH - Broadcast Channel The Broadcast Channel (BCH) is a downlink transport channel that is used to broadcast system and cell-specific information. The BCH is always transmitted over the entire cell and has a single transport format. 4.1.2.2 FACH - Forward Access Channel The Forward Access Channel (FACH) is a downlink transport channel. The FACH is transmitted over the entire cell or over only a part of the cell using e.g. beam-forming antennas. The FACH can be tr
