32、 available The present document collects together temporary documents of ETSI SMG and STC SMG2 and 3GPP GERAN which can be seen as base line material for the RF requirements in GSM 05.05. The documents are divided into several clauses In each clause there is a short description of the documents. The
33、 documents themselves are annexed to this report. A list of phase 2 change requests to SMG2 related documents are annexed to the SMG meeting reports. 3 DCS1800 system scenarios There are two documents describing the basis of the DCS1800 RF requirements. They are: - DCS1800 System scenarios (TDoc SMG
34、 259/90, reproduced as TDoc SMG 60/91). - Justifications for the DCS1800 05.05 (TDoc SMG 260/90, revised as TDoc SMG 60/91). These documents have been derived first by the UK PCN operators and later by GSM2 ad hoc group working on DCS 1800 requirements during 1990. The documents were presented to TC
35、 SMG in October 1990. DCS1800 System Scenarios describes six scenarios which are considered to be the relevant cases for DCS1800. The six scenarios described are: - Single MS - Single BTS. - Multiple MSs - Multiple co-ordinated BTSs. - Multiple MSs - Multiple uncoordinated BTSs. ETSI ETSI TR 145 050
36、 V14.0.0 (2017-04)243GPP TR 45.050 version 14.0.0 Release 14- Co-located MSs, co-ordinated/uncoordinated. - Co-located BTSs, co-ordinated/uncoordinated. - Co-location with other systems. On each of these scenarios the system constraints related to the scenario are described, the RF requirements affe
37、cted by the scenario are identified and the input information needed to study the scenario in detail is listed. Justifications for the DCS1800 05.05 includes the analysis of the system scenarios to detailed RF requirements and presents and justifies the proposed changes to GSM 05.05 for DCS1800. In
38、the analysis part the relevant scenario calculations are made for each RF requirement and the most critical scenario requirement identified. The justification part then looks at the identified scenario requirement, compares it to the corresponding existing GSM900 requirement and taking also into acc
39、ount the implementation issues and finally gives reasoning to the proposed change of the specific RF requirement. These documents are in annex A. The DCS1800 requirements were originally developed for Phase 1 as a separate set of specifications, called DCS-specifications. For Phase two the DCS1800 a
40、nd GSM900 requirements are merged. The main Phase 2 change requests of SMG2 in which the requirements for the DCS1800 system were included into are listed below. - CR 05.01-04 Combination of GSM900 and DCS1800 specifications. - CR 05.05-37 rev1 Combination of 05.05 (GSM900) and 05.05-DCS (DCS1800) s
41、pecifications. - CR 05.08-55 rev1 Combination of GSM900 and DCS1800 and addition of National roaming. Further development of the DCS1800 requirements for Phase 2 can be found in the other Phase 2 CRs of SMG2, the vast majority of which are valid both for DCS1800 and GSM900. The list of Phase 2 CRs o
42、f SMG2 can be found in annex E. 4 GSM900 small cell system scenarios There is one document which discusses the small cell system scenarios for GSM900. The document is: - Small cell system scenarios for GSM900 (TDoc SMG2 104/92, revised as TDoc SMG2 104/92 rev1). Small cell system scenarios for GSM90
43、0 uses the DCS1800 system scenarios and justification document and derives from them the scenario requirements for GSM900 small cells. It also calculates the worst case requirements based on minimum coupling loss of 59 dB. The document on GSM900 small cell system scenarios is in annex B. CR 03.30-02
44、 on “Propagation models for different types of cells“ gives a definition for a small cell and the typical cell parameters to calculate the propagation loss in a small cell. 5 GSM900 and DCS1800 microcell system scenarios GSM900 and DCS1800 microcells have been discussed by SMG2 in various meetings s
45、ince late 1991. In SMG2#2 (May 1992) a small group was formed to collect together the various documents and make a proposal for the microcell RF parameters. As agreed by SMG2 there should be four microcell specific requirements, namely: - transmit power; - receive sensitivity; - wideband noise; - bl
46、ocking. ETSI ETSI TR 145 050 V14.0.0 (2017-04)253GPP TR 45.050 version 14.0.0 Release 14As a result of the subgroup and other SMG2 activities there are three documents which can be used as baseline material for the microcell requirements. They are: - Microcell BTS RF parameters (TDoc SMG2 163/92); -
47、 Comments and proposals on Microcell RF parameters (TDoc 144/92); - Revised proposal for microcell RF parameters (TDoc SMG2 ad hoc 4/92). Microcell BTS RF parameters and Comments and proposals on Microcell RF parameters are joint papers giving the microcell scenarios and the requirements. The first
48、one describes the two microcell scenarios, namely range and proximity, and presents the method to derive the detailed requirements starting from the scenarios. The latter document includes some corrections/updates to the scenarios, and proposes the detailed requirements. As described in the document
49、s there are three classes of microcells, depending on the expected Minimum Coupling Loss between BTS and MS. This is to guarantee the optimum choice of BTS transmit powers while maintaining the operability of the system. The last of the microcell documents, Revised proposal for microcell RF parameters includes updates to the detailed requirement figures. All the microcell requirements were collected together and were presented to and approved by SMG#5. The documents on GSM900 and DCS1800 microcells are in annex C. The relevant change requests where the detailed micro
