The applicability of this whole multi-part deliverable to MP equipment

ETSI ETSI EN 302 326-2 V1.2.2 (2007-06) 10The present document is considered applicable to fixed radio systems products with

10、integral antennas, for which all the technical requirements included in the present document and in EN 302 326-3 12 apply, and to separate equipment products, to which only the relevant technical requirements apply, and which might therefore be subject to separate declarations of conformity with res

The manufacturer shall indicate, in the Technical Construction File or elsewhere, the pro

26、N 302 326-3: “Fixed Radio Systems; Multipoint Equipment and Antennas; Part 3: Harmonized EN covering the essential requirements of article 3.2 of the R in this way for most of the time the interference is reduced and the transmitter operates in a higher linearity mode NOTE 1: When this function is u

27、sed, the transmit power is dynamically changed with respect the propagation conditions. In principle, when ATPC is implemented, three different level of power may be identified: square4 maximum available power (delivered only in conditions of deep fading); square4 maximum nominal power (useable on a

28、 permanent basis when ATPC is disabled); it should be noted that this power is “nominal for the equipment“ and is not to be confused with the “nominal level set link by link“ by the frequency co-ordinating body. This is achieved through passive RF attenuators or use of the RTPC type 1 function; squa

29、re4 minimum power (delivered in unfaded conditions). NOTE 2: Maximum nominal and maximum available power levels may be coincident or, in case of multi-state modulation formats, the maximum available power may be used to overdrive the transmitter (losing linearity but gaining fade margin when the fad

30、e conditions have already impaired the expected RBER). Performance predictions are usually made with the maximum “available power“. Central Station (CS): base station which communicates with Terminal Stations and in some cases Repeater Stations Channel Separation (ChS): separation between the centre

31、 frequencies of neighbouring RF channels according ITU-R Recommendation F.746 (see bibliography) and used for adjacent channel interference requirements NOTE 1: In some access methodologies the whole channel given to the system is subdivided in sub-channels for use by subsets of terminal stations; h

32、owever also in this case the channel separation is still intended in the same way as the above definition (minimum continuous segment of bandwidth made available to the system). NOTE 2: In this whole multi-part deliverable Channel Separation (ChS) is a free variable the value(s) of which the supplie

33、r declares. Limiting values of some other parameters which are requirements of the present document are expressed as functions of ChS. CEPT Recommendations and national administrations may replace restrictions on which ChS values are permitted. DS-CDMA Full Capacity Load (FCL): maximum number of 64

34、kbit/s signals or equivalent which can be transmitted and received by a single CS within a specified RF-bandwidth, fulfilling given performance and availability objectives in respect to fading conditions DS-CDMA maximum system loading: maximum possible payload data rate on a single RF channel for th

35、e class of operation declared by the manufacturer Downlink: direction of traffic flow from Central Station towards a Terminal Station Equipment Classification (EqC): multi-field classification which indicates the principal characteristics of a particular equipment within the scope of EN 302 326 and

36、indicates which alternative consistent sets of requirements of EN 302 326 apply to that equipment FDMA signal: signal comprising all permitted carriers in a channel at full system load ETSI ETSI EN 302 326-2 V1.2.2 (2007-06) 17FH-CDMA Frequency Hopping (FH): spread spectrum technique whereby individ

37、ual radio links are continually switched from one sub-channel to another NOTE: Such links are not constrained to a single RF channel. FH-CDMA hopping sequence: sequence of sub-channels which a particular link follows FH-CDMA slow frequency hopping: FH technique where the hopping period is larger tha

39、ain (of an antenna): ratio of the radiation intensity, in a given direction, to the radiation intensity that would be obtained if the power accepted by the antenna was radiated isotropically gross bit rate: transmission bit rate over the air. In case of a transmitter working in burst mode, the gross

40、 bit rate is the instantaneous maximum transmission bit rate during the burst NOTE: The gross bit rate has a unique relationship to the symbol rate through the implemented modulation format. In the case of OFDMA this relationship is unique when all OFDMA sub-carriers are in use. Gross bit rate for T

41、DMA/OFDMA systems is the aggregate bit rate of all OFDMA sub-carriers transmitting simultaneously; (e.g. for a TDMA/OFDMA system, in any single TDMA burst any single OFDMA TS may be dynamically assigned a subset of the OFDMA-sub-channels. Multiple TS are allowed to transmit at the same time on disjo

42、int sets of OFDM-sub-carriers, so the MGBR is defined when all available OFDM-sub-carriers are in use at the same time). hopping sequence: See FH-CDMA hopping sequence. integral antenna: antenna which is declared as part of the radio equipment by the supplier NOTE: Even when equipment with integral

43、antenna is concerned, it may still be possible to separate the antenna from the equipment using a special tool. In such cases the assessment of the radio equipment and of the antenna against requirements of this whole multi-part deliverable could be done separately by the actual supplier(s). Maximum

44、 System Loading (MSL): (only defined for DS-CDMA systems) See “DS-CDMA maximum system loading“. ETSI ETSI EN 302 326-2 V1.2.2 (2007-06) 18mixed-mode system: system having the capability for stations (CS or TS or RS) to operate on different modulation orders and/or switch dynamically between differen

45、t modulation orders NOTE: This capability may be used to improve deployment and capacity capabilities or to adaptively adjust for varying channel impairments, or to improve spectral efficiency by dynamically allocating transmission capacity. The switching between modulation orders may occur as frequ

46、ently as appropriate to the system, (e.g. on a per-burst or per-timeslot or per-carrier basis). multi-carrier system: system where more than one modulated sub-carrier is radiated from the same transmitter NOTE 1: A system that uses several transmitters into a non-active antenna is not considered as

47、a multi-carrier system. Systems using FDM/OFDM modulation formats are also not considered multi-carrier unless more that one separate FDM/OFDM signal set is transmitted from the same transmitter. NOTE 2: FDMA systems are intrinsically multicarrier, because any single sub-carrier may be easily discri

48、minated at RF level (unlike OFDM modulations) and activated according to the traffic requirements. However, for the purpose of the present document, a FDMA system are also considered as a whole (fully loaded) single signal set (comprised of multiple carriers), unless more that one FDMA signal set is

49、 transmitted from the same transmitter. Nomadic Wireless Access (NWA): “Wireless access“ application in which the location of the “end-user termination“ may be in different places but it must be stationary while in use NOTE: See ITU-R Recommendation F.1399 in bibliography. nominal output power: maximum output power of the Central Station (CS), Terminal Station (TS) or Repeater Station (RS) referred to point C of figure 3 under the full load condition declared by the manufacturer NOTE: This power may, however, be exceeded by the action of
