Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present doc
18、ument 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 9. This modification has been approved at ITU-R SG8 meeting in November 2005. The present document is part 1, sub-part 1 of a multi-part deliverable
19、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“; Sub-part 1: “G-family (S-UMTS-G 25.211)“; Sub-part 2: “A-family (S-UMTS-A 25.211)“; Part 2:
20、“Multiplexing and channel coding“; 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“. Introduction S-UMTS stands for the Satellite component of the Unive
21、rsal 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 Services (MSS) utilizing either geostationary (GEO), or lo
22、w (LEO) or medium (MEO) earth orbiting 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 differ
23、ences 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, whilst some
24、 S-UMTS specifications have no corresponding T-UMTS specification. ETSI ETSI TS 101 851-1-1 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 b
25、een 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, B, C, etc.) denotes the family of S-UMTS specification
26、s. 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 precedence rule applies to any references in the corresponding 3G
27、PP 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. If an S-UMTS specification does not exist, the correspo
28、nding 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 101 851-1-1 V2.1.1 (2008-01) 7 1 Scope The present document defines the Layer 1 transport channels and physical channels used for family
29、G of the satellite component of UMTS (S-UMTS-G). It is based on the FDD mode of UTRA defined by TS 125 201 4, TS 125 211 8, TS 125 302 5 and TS 125 435 6 and adapted for operation over satellite transponders. 2 References References are either specific (identified by date of publication and/or editi
30、on 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 changes of the r
31、eferenced 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 sufficient to identi

45、UE User Equipment USRAN UMTS Satellite Radio Access Network 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 TS 125 302 5. A transport channel is defined by h
46、ow and with what characteristics data is transferred over the air interface. 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
47、 channels There exists only one type of dedicated transport channel, the Dedicated CHannel (DCH). 4.1.1.1 Dedicated CHannel (DCH) The Dedicated CHannel (DCH) is a downlink or uplink transport channel. The DCH is transmitted over the entire spot or over only a part of the spot using e.g. beam-forming
48、 antennas. 4.1.2 Common transport channels There are four types of common transport channels: BCH; FACH; PCH; and RACH. 4.1.2.1 Broadcast CHannel (BCH) The Broadcast CHannel (BCH) is a downlink transport channel that is used to broadcast system- and spot-specific information. The BCH is always trans
49、mitted over the entire spot and has a single transport format. 4.1.2.2 Forward Access CHannel (FACH) The Forward Access CHannel (FACH) is a downlink transport channel. The FACH is transmitted over the entire spot. The FACH can be transmitted using power setting described in TS 125 435 6, i.e. with “Transmit Power Level“ of the “FACH DATA FRAME“ Frame Protocol message. 4.1.2.3 Paging CHannel (PCH) The Paging CHannel (PCH) is a downlink transport channel. The PCH is always transmitted over the entire spot. The transmission of th
