Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The presen
18、t 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.1457-5. This modification has been approved at ITU-R SG8 meeting in November 2005. The contents of the present document are subject to continuing wor
19、k 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 digit (n) is incremen
20、ted when editorial only changes have been incorporated in the specification; the second digit (m) is incremented for all other types of changes, i.e. technical enhancements, corrections, updates, etc. The present document is part 1 of a multi-part deliverable covering Satellite Earth Stations and Sy
21、stems (SES); Satellite Component of UMTS/IMT2000; G-family, as identified below: Part 1: “Physical channels and mapping of transport channels into physical channels (S-UMTS-A 25.211)“; Part 2: “Multiplexing and channel coding (S-UMTS-A 25.212)“; Part 3: “Spreading and modulation (S-UMTS-A 25.213)“;

Introduction S-UMTS stands for the Satellite component of the Universal Mobile Telecommunication System. S-UMTS systems
23、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 low (LEO) or medium (MEO) earth orbiting satellite(s).
24、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 101 851-1 V1.2.1 (2006-01) 6 Due to the differences betw
25、een 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 S-UMTS sp
26、ecifications 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 terrestrial UMT
27、S 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 combination of a fam
28、ily 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 to 3GPP specific
29、ations 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 apply. The exact a
30、pplicability of the complete list of 3GPP specifications shall be defined at a later stage. ETSI ETSI TS 101 851-1 V1.2.1 (2006-01) 7 1 Scope The present document defines the Layer 1 transport channels and physical channels used for family G of the satellite component of UMTS (S-UMTS-G). It is based
31、 on the FDD mode of UTRA defined by TS 125 201 4, TS 125 211 5, TS 125 302 6 and TS 125 435 7 and adapted for operation over satellite transponders. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

43、r layers. General concepts about transport channels are described in TS 125 302 6. A transport channel is defined by how 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 a
44、ddressing 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, the Dedicated CHannel (DCH). ETSI ETSI TS 101 851-1 V1.2.1 (2006-01) 9 4.1.1.1 DCH - Dedicated Channel The Dedica
45、ted 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 antennas. 4.1.2 Common transport channels There are four types of common transport channels: BCH; FACH; PCH; and RACH. 4.1.2.1 BCH - Broadc
46、ast Channel The Broadcast CHannel (BCH) is a downlink transport channel that is used to broadcast system- and spot-specific information. The BCH is always transmitted over the entire spot and has a single transport format. 4.1.2.2 FACH - Forward Access Channel The Forward Access CHannel (FACH) is a
47、downlink transport channel. The FACH is transmitted over the entire spot. The FACH can be transmitted using power setting described in TS 125 435 7, i.e. with “Transmit Power Level“ of the “FACH DATA FRAME“ Frame Protocol message. 4.1.2.3 PCH - Paging Channel The Paging CHannel (PCH) is a downlink t
48、ransport channel. The PCH is always transmitted over the entire spot. The transmission of the PCH is associated with the transmission of physical-layer generated Paging Indicators, to support efficient sleep-mode procedures. 4.1.2.4 RACH - Random Access Channel The Random Access CHannel (RACH) is an
49、 uplink transport channel. The RACH is always received from the entire spot. The RACH is characterized by a collision risk and by being transmitted using open loop power control. 4.2 Indicators Indicators are means of fast low-level signalling entities which are transmitted without using information blocks sent over transport channels. The meaning of indicators is specific to the type of indicator. The indicators defined in the current version of the specifications are: Acquisition Indicator (AI); Page Indicator (PI); and
