The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http://webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (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). 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 24,25 GHz to 29,5 GHz using different access methods, as identified below: Part 1: "Basic parameters"; Part 2: "Frequency Division Multiple Access (FDMA) methods"; Part 3: "Time Division Multiple Access (TDMA) methods"; Part 4: "Direct Sequence Code Division Multiple Access (DS-CDMA) methods"; Part 5: "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 Therefore similar information for multicarrier systems has been removed from the present document being redundant and superseded by EN 301 213-5 [4].

ETSI ETSI EN 301 213-3 V1.4.1 (2002-02) 6 1 Scope The present document describes the TDMA access method used in Point-to-Multipoin (P-MP) Radio Relay Systems. (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 document (Time Division Multiple Access Methods, TDMA) is to be used in conjunction with EN 301 213-1 [1], 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; multicarrier 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) Radio 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 [1]. Time Division Multiple Access (TDMA) is an alternative to FDMA and CDMA covered in other 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 sharing it through time multiplexing. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
