Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). Introduction The objective of using W-
45、CDMA in a satellite environment is to ease integration of satellite and terrestrial UMTS. Some of the benefits to be gained from a fully integrated S-UMTS/T-UMTS system are: seamless service provision; re-use of terrestrial equipment: User Equipment and network infrastructure equipment (Node B, RNC,
46、 etc.); highly integrated multi-mode terrestrial/satellite terminals. The satellite component of UMTS may provide services: in areas covered by cellular terrestrial systems, where terrestrial coverage requires capacity complement; in areas where terrestrial coverage is not available: - because terre
47、strial networks have not been deployed for business attractiveness reasons; or - because terrestrial system has suffered environmental damages (crisis conditions). Based on the methodology defined by ITU-R, the outline of the present document is the following: In clause 4, the system architecture an
48、d examples of candidate satellite constellations are presented. Clause 5 summarizes key characteristics based on the Technical Specifications defined by 3GPP. Adaptation of radio resource functions to satellite environment is approached. Clause 6 specifies test environment and equipment performance
49、requirements. Clause 7 presents system capacity. Clause 8 summarizes constraints due to satellite environment. The concluding clause 9 is a brief summary of the results established so far. The present document is completed with five annexes. Annexes A and B specify reference measurement channels. Annex C provides typical link budgets. Annex D presents detailed system capacity results. Annex E is the ITU-R template used in M.1225 1 the evaluation of the Radio Interfaces. ETSI ETSI TR 102 058 V1.1.1 (2004-11) 9 1 Scope The present document evaluates the feasibility to
