Foreword The present Technical Report (TR) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). Introduction The objective of W-CDMA Satellite Radio Interface is to ease integration
33、of satellite and terrestrial UMTS. One promising application is provision of Multimedia Broadcast/Multicast Service (MBMS). Some of the benefits to be gained from a fully integrated S-UMTS/T-UMTS system are: seamless service provision; highly integrated multi-mode terrestrial/satellite User Equipmen
34、t (UE); reuse of terrestrial equipment: radio access infrastructure equipment (RNC, Node B, etc.). The satellite component of MBMS may provide services: in areas covered by cellular terrestrial systems, for complementary services such as broadcast/multicast; in areas where terrestrial coverage is no
35、t available: - because terrestrial network have not been deployed for business attractiveness reasons; or - because terrestrial infrastructure has suffered environmental damages (crisis conditions). The present document is applicable to several satellite constellation types (for LEO and MEO constell
36、ations, addition of Doppler and synchronization adaptation module). The outline of the present document is the following: Clause 4: “Satellite Multimedia Broadcast/Multicast Service“, the system architecture and candidate satellite constellations are presented. Clause 5: “W-CDMA Satellite Radio Inte
37、rface“ summarizes key characteristics based on the Technical Specifications defined by 3GPP. Clause 6 specifies test environment and equipment performance requirements. Clause 7: “System performances“ presents link budgets and system capacity. ETSI ETSI TR 102 277 V1.2.1 (2007-02) 8 Clause 8: “Techn
38、ology design constraints“ summarizes constraints due to satellite environment. The concluding clause 9 “Conclusion“ is a brief summary of the results established so far. The present document is completed with four annexes. Annex A specifies reference measurement channels. Annexes B, C and D present
39、Comparison of S-MBMS performance and system radio capacity with and without soft combining in IMR environment. ETSI ETSI TR 102 277 V1.2.1 (2007-02) 9 1 Scope The feasibility of using W-CDMA UTRA FDD as a satellite radio interface has been shown in ETSI TR 102 058 6. Based on this, ITU has adopted t
40、his radio interface as G family in ITU-Rec M 1455 3 and ITU-Rec M 1457 4. This radio interface has been standardized within the TC SES S-UMTS working group as family G in TS 101 851-1 to 4 7 to 10. The present document evaluates the feasibility to use S-UMTS interface G (W-CDMA UTRA FDD) for provisi
41、on of Satellite Multimedia Broadcast/Multicast Service (S-MBMS). The Technical Specifications for the W-CDMA UTRA FDD has been developed in the framework of the third Generation Partnership project (3GPP). The analysis for applicability to satellite is based on 3GPP standards as defined from 11 to 2
