18、.0.0 (2016-01)43GPP TS 25.111 version 13.0.0 Release 13Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the

19、TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indica

20、tes TSG approved document under change control. Y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction In order to ensure

21、 correctness and consistency of 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 contr

22、ol, change control, document updating, 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

23、changes that are brought into 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 a

24、nd consistency of the specifications 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.

33、le Access 4 General 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 comm

34、unication link 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 specificati

35、on apply to Wide 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

36、 coupling loss 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 LMU“s relationship with other network elements. The LMU

37、 is typically located 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.

39、performing these functions. 5.1 Frequency bands a) The LMU is designed to operate in the following bands: Table 4.1: Frequency bands Operating Band UL Frequencies UE transmit, LMU receive I 1920 1980 MHz II 1850 -1910 MHz III 1710-1785 MHIV 1710-1755 MHz V 824 849MHz VI 830-840 MHz VII 2500 2570 MHz

The receiver shall fulfil a specified BER

43、 requirement for a specified sensitivity degradation of the wanted signal in the presence of an interfering AWGN signal in the same reception frequency channel. The BER shall not exceed 0.001 for the parameters specified in Table 4.3. Table 4.3: Dynamic range Parameter Level Wide Area LMU Level Medi

ACS is the ratio of the LMU receiver filter attenuation on the assigned channel frequency to the receiver filter attenuation on the adjacent chan
