23、f the specifications (i.e., technical specifications and technical reports) under responsibility of the Technical Specification Groups (TSG) of the 3rdGeneration Partnership Project (3GPP), clear, manageable and efficient mechanisms are necessary to handle version control, change control, document u

24、pdating, distribution and management. Also, the fact that the specifications are/will be implemented by industry almost in parallel with the writing of them requires strict and fast procedures for handling of changes to the specifications. It is very important that the changes that are brought into

25、the standard, from the past, at present and in the future, are well documented and controlled, so that technical consistency and backwards tracing are ensured. The 3GPP TSGs, and their sub-groups together with the Support Team are responsible for the technical content and consistency of the specific

26、ations whilst the Support Team alone is responsible for the proper management of the entire documentation, including specifications, meeting documents, administrative information and information exchange with other bodies.

28、cific (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 reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-

29、specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TS 25.104: “Base Station (BS) radio transmission and reception (FDD)”. 2 3GPP TS 45.004: “Modulation”. 3 3GPP TS 25.141: “Base Station (BS) conformance testing (FDD)”. 4 3G

A term defined in the prese

Mean power: When applied to a W-CDMA modulated signal this is the power (transmitted or received) in a bandwidth of at least (1+ ) times the chip rate of the radio access mode. The period of measurement shall

32、be at least one timeslot unless otherwise stated. NOTE: The roll-off factor is defined in clause 6.8.1 of 1. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 21.905 5 and the following apply.

35、neral 4.1 Main concepts The LMU is either located as a separate unit in an existing network or typically located at Node B or BTS sites. Therefore the LMU radio requirements assume that the isolation between the LMU and any other network to be protected is to be at least 30dB. The communication link

36、 between LMU and Stand-Alone SMLC is not a radio interface over the air. Requirements in this document therefore do not cover the situation when the LMU is transmitting over the air on this interface between LMU and Stand-Alone SMLC. 4.2 LMU Classes The requirements in this specification apply to Wi

37、de Area LMUs and Medium Range LMUs. Wide Area LMUs are characterised by requirements derived from Macro Cell scenarios with an LMU to UE minimum coupling loss equal to 70 dB. Medium Range LMUs are characterised by requirements derived from Micro Cell scenarios with an LMU to UE minimum coupling loss

38、 equal to 53 dB. For Pico Cell scenarios, the location of the BS provides sufficient accuracy; therefore, a Local Area LMUs class is not specified. 4.3 U-TDOA architecture A sample architecture is shown in Figure 3.1 depicting the LMUs relationship with other network elements. The LMU is typically l

39、ocated at the Node B. The LMUs communicate with the SMLC that distributes UTDOA reference data from the reference LMU to other cooperating LMUs when performing UE positioning.

40、 radio characteristics An LMU performs BS receiver functions to obtain reference data for use at a cooperating LMU. The following clause describes the required LMU radio characteristics when performing these functions. 5.1 Frequency bands a) The LMU is designed to operate in the following bands: Tab

The receiver shall fulfil a specified BER requirement fo

45、r a specified sensitivity degradation of the wanted signal in the presence of an interfering AWGN signal in the same reception frequency channel.

ACS is the ratio of the LMU receiver filter attenuation on the assigned channel frequency to the receiver filter attenuation on the adjacent channel(s). The int
