ETSI ETSI TR 145 050 V15.0.0 (2018-07)233GPP TR 45.050 version 15.0.0 Release 151 Scope 1.1 General The present document gives background information on how the RF requirements of GSM400, GSM900 and DCS 1800 systems have been derived. 1.2 References The following documents contain provi
31、sions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific
32、reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 45.820, “Cellular System Support for Ultra Low Com

34、PP 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 documents themselves are annexed to this report. A list of phase 2 change requests to SMG2 related d
35、ocuments 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 259/90, reproduced as TDoc SMG 60/91). - Justifications for the DCS1800 05.05 (TDoc SMG 260/90, revi
36、sed 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 SMG in October 1990. DCS1800 System Scenarios describes six scenarios which are considered to be the
37、 relevant cases for DCS1800. The six scenarios described are: - Single MS - Single BTS. - Multiple MSs - Multiple co-ordinated BTSs. - Multiple MSs - Multiple uncoordinated BTSs. - Co-located MSs, co-ordinated/uncoordinated. - Co-located BTSs, co-ordinated/uncoordinated. ETSI ETSI TR 145 050 V15.0.0
38、 (2018-07)243GPP TR 45.050 version 15.0.0 Release 15- Co-location with other systems. On each of these scenarios the system constraints related to the scenario are described, the RF requirements affected by the scenario are identified and the input information needed to study the scenario in detail
39、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 the analysis part the relevant scenario calculations are made for each RF requirement and the most cr
40、itical 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 account the implementation issues and finally gives reasoning to the proposed change of the specific RF
41、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 and GSM900 requirements are merged. The main Phase 2 change requests of SMG2 in which the requirements
42、 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) specifications. - CR 05.08-55 rev1 Combination of GSM900 and DCS1800 and addition of National roaming.
43、 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 of SMG2 can be found in annex E. 4 GSM900 small cell system scenarios There is one document which disc
44、usses 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 GSM900 uses the DCS1800 system scenarios and justification document and derives from them the scenario req
45、uirements 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 on “Propagation models for different types of cells“ gives a definition for a small cell and the typ
46、ical 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 since late 1991. In SMG2#2 (May 1992) a small group was formed to collect together the various documen
47、ts 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; - blocking. ETSI ETSI TR 145 050 V15.0.0 (2018-07)253GPP TR 45.050 version 15.0.0 Release 15As a result o
48、f 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); - Comments and proposals on Microcell RF parameters (TDoc 144/92); - Revised proposal for microcell RF
49、 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 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 documents there are three classes of microcells, depending on the expected Minimum
