Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplex

16、ing (TM). The present document contains the minimum technical requirements to ensure compatibility of products and conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not required to interwork at radio frequency (i.e. no common air interface

17、). The present document defines the requirements of radio terminal and radio-relay equipment and associated interfaces. The present document is part 3 of a multipart deliverable covering the Point-to-multipoint equipment; Point-to-multipoint digital radio systems in frequency bands in the range 24,2

18、5 GHz to 29,5 GHz using different access methods, as identified below: Part 1 : “Basic parameters“; Part 2: Part 3: Part 4: Part 5: “Frequency Division Multiple Access (FDMA) methods“; “Time Division Multiple Access (TDMA) methods“; “Direct Sequence Code Division Multiple Access (DS-CDMA) methods“;

19、“Multi-Carrier Time Division Multiple Access (MC-TDMA) methods“. The present version of the document takes into account that, with the final publication of EN 301 213-5 4, information and requirements relative to multicarrier systems are now more organically reported there. Therefore similar informa

20、tion for multicarrier systems has been removed from the present document being redundant and superseded by EN 301 213-5 4.

22、(P-MP) Radio Relay Systems may use different access methods. As some technical parameters are different for the various access methods, the standard is divided in four parts. A basic description of the different access methods and a comparison among them is provided in TR 101 274 2. The present docu

23、ment (Time Division Multiple Access Methods, TDMA) is to be used in conjunction with EN 301 213-1 i, describing the basic parameters common to all access methods. The present document is related to characteristics of system operating with transmitters delivering to antenna port one single carrier; m

24、ulticarrier systems (where more than one carrier is passed through the same final power amplifier or active antenna are considered in EN 301 213-5 4). The present document specifies the minimum requirements for system parameters of Time Division Multiple Access (TDMA) Point-to-Multipoint (P-MP) Radi

25、o Systems in the terrestrial fixed services operating in the band 24,5 GHz to 29,5 GHz (see ERC/REC T/R 13-02 3). Only sections specific to TDMA are described in respect to the paragraphs stated in EN 301 213-1 i. Time Division Multiple Access (TDMA) is an alternative to FDMA and CDMA covered in oth

26、er parts of the present document. In TDMA Point-to-Multipoint (P-MP) systems, a central station broadcasts information to terminal stations in a continuous Time Division Multiplex (TDM) or in a burst TDMA mode. The Terminal stations transmit in TDMA mode. The users may have access to the spectrum by

27、 sharing it through time multiplexing. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

33、during the burst. The gross bit rate has a unique relation to the symbol rate through the implemented modulation format. 3.2 Symbols For the purposes of the present document the symbols given in EN 301 213-1 i apply. 3.3 Abbreviations For the purposes of the present document the abbreviations defiie

37、n clause 3.1. The manufacturer shall declare the actual system traffic carrying capacity, the gross bit rate and the System IOTE 2: Systems may offer a combination of Type A, Type B, Type C and Type HC on a per Terminal Station basis, provided that such a system, when operating in mixed mode, compli

38、es with: - the most stringent spectral mask for the types offered when Co-ordination between different operators operating on first adjacent channels is envisaged; - with the mask declared by the manufacturer when block of channels are assigned according to ERC/REC 00-05 5 and ERC/REC 01-03 6. IOTE

39、3: The present document defines four System Types A, B C and HC. These systems represent different spectral efficiency in term of gross-bit-rate/Hz; the gross bit rate, defined in clause 3.1, has a unique relation to the symbol rate through the implemented modulation format as follows: - A: lower co

40、mplexity modulation formats (e.g. 4 states or equivalent); - HC: lower complexity modulation formats as System Type A (e.g. 4 states or equivalent), but with higher requirements for receiver sensitivity and tolerance to interference; - B: medium complexity modulation formats (e.g. 16 states or equiv

41、alent); - C: higher complexity modulation formats (e.g. 64 states or equivalent). IOTE 4: For regulatory purposes in national procedures for licensing radio equipments according to the present document, the above system types shall be identified by the “system type codes“ reported in annex A. Type.

42、The CRS transmission, defined as the “downstream“ direction, may be continuous, i.e. TDM (Time Division Multiplex). The CRS may transmit in the downstream direction even if there are no active calls, for the purpose of synchronization of the Terminal Stations. The Terminal Stations (TS) may transmit

43、 only in timeslots allocated by control signals from the CS, or on a fixed basis. The TS transmission direction is defined as “upstream“. TS may transmit in a TDMA basis. A TS may transmit control, bandwidth requests or signalling information even during the absent of users activities. TS transmissi

44、ons consist of bursts of fixed or variable duration, usually an integer multiple of a fundamental timeslot duration. 4.3 Com pati bi I i ty requirements Refer to EN 301 213-1 i, clause 4.3. 4.4 Envi ron m e n ta I cond i ti ons Refer to EN 301 213-1 i, clause 4.4.
