The manufacturer should recommend the net power gain or loss of the antenna system to be installed with the mobile station such that the power me
16、asured at the transmitter output terminals can be directly related to the required ERP (typical antenna systems have 2.5 dB gain with respect to a half-wave dipole and 1.5 dB cable loss). The station class indicated by the mobile station at the beginning of any call will be assumed by the system to
17、be maintained throughout that call.

All four bits of MAC are used in the DMAC field. NOTE 2: The output powers shown above shall be maintained within th
19、e range of +2 dB, -4 dB of nominal value for Power Levels 0 7, and within +2 dB, -6 dB of the nominal value for Power Levels 8 10 (see Note 3). NOTE 3: The Nominal Output Power for levels 8, 9, and 10 are expressed as a range, rather than an absolute value. When the mobile station changes to one of
20、these power levels, it shall insure that it stabilizes within the range centered around the target value for that level. For example, the target value for power level 8 in the 1900 MHz operating band is -28dBW. The mobile station is considered to be within the requirement provided it stabilizes with
21、in 4dB of this target level. Once the mobile station has stabilized, the operating tolerance is applied to the specific value within the nominal range on which the mobile station stabilized.

Additionally, the mobile station shall satisfy the requirements identified for the Relative Step Accuracy going into the X+1 Power Level
24、. Thus, the mobile station shall reduce its power such that it conforms to the Nominal level, with a reduction in power at least as great as the minimum specified by the Relative Step requirement. 4.1.2 Base Station The micro-BTS maximum output power per carrier measured at the antenna connector aft
25、er all stages of combining shall be, according to its class, defined in the following table. Table 4.5 Micro-BTS Maximum Output Power per Carrier 800 MHz micro and pico-BTS 1900 MHz micro and pico-BTS TRX power class Maximum output power TRX power class Maximum output power Micro Micro M1 ( 19) - 24
26、 dBm M1 ( 27) - 32 dBm M2 ( 14) - 19 dBm M2 ( 22) - 27 dBm M3 ( 9) - 14 dBm M3 ( 17) - 22 dBm Pico Pico P1 ( 13) - 20 dBm P1 ( 16) - 23 dBm For BTS supporting 8-PSK, the manufacturer shall declare the output power capability at 8-PSK modulation. For BTS supporting Offset Quadrature Ampitude Modulati
27、on (O-QAM), the manufacturer shall declare the output power capability at O-QAM modulation. The class of a micro-BTS or a pico-BTS is defined by the highest output power capability for either modulation and the output power shall not exceed the maximum output power of the corresponding class. The to
28、lerance of the actual maximum output power of the BTS shall be 2 dB under normal conditions and 2.5 dB under extreme conditions. Settings shall be provided to allow the output power to be reduced from its maximum level in at least six steps of nominally 2 dB with an accuracy of 1 dB to allow a fine
29、adjustment of the coverage by the network operator. In addition, the actual absolute output power at each static RF power step (N) shall be 2*N dB below the absolute output power at static RF power step 0 with a tolerance of 3 dB under normal conditions and 4 dB under extreme conditions. The static
30、RF power step 0 shall be the actual output power according to the TRX power class. As an option the BSS can utilize downlink RF power control. In addition to the static RF power steps described above, the BSS may then utilize up to 15 steps of power control levels with a step size of 2 dB 1.5 dB, in
31、 addition the actual absolute output power at each power control level (N) shall be 2*N dB ATIS-0700019 9 below the absolute output power at power control level 0 with a tolerance of 3 dB under normal conditions and 4 dB under extreme conditions. The power control level 0 shall be the set output pow
32、er according to the TRX power class and the six power settings defined above. Network operators or manufacturers may also specify the BTS output power including any Tx combiner, according to their needs. 4.1.2.1 Additional Requirements for 1900 MHz Base Stations The BTS transmitter maximum rated out
33、put power per carrier, measured at the input of the transmitter combiner, shall be, according to its TRX power class, as defined in Table 4.5. The base station output power may also be specified by the manufacturer or system operator at a different reference point (e.g., after transmitter combining)
34、. 4.1.2.2 Additional Requirements for 800 MHz Base Stations The BTS transmitter maximum rated output power per carrier, measured at the input of the transmitter combiner, shall be, according to its TRX power class, as defined in Table 4.5. The base station output power may also be specified by the m
35、anufacturer or system operator at a different reference point (e.g., after transmitter combining). 4.2 Output RF Spectrum The specifications contained in this section apply to both BTS and MS, in frequency hopping as well as in non frequency hopping mode, except that beyond 1800 kHz offset from the
36、carrier the BTS is not tested in frequency hopping mode. Due to the bursty nature of the signal, the output RF spectrum results from two effects: the modulation process; and the power ramping up and down (switching transients). The two effects are specified separately; the measurement method used to
37、 analyse separately those two effects is specified in 3GPP TS 51.010-1 and 51.021. It is based on the “ringing effect“ during the transients, and is a measurement in the time domain, at each point in frequency. The limits specified thereunder are based on a 5-pole synchronously tuned measurement fil
38、ter. Unless otherwise stated, for the BTS, only one transmitter is active for the tests of this section. 4.2.1 Spectrum Due to the Modulation A continuous, static sine wave signal at a level as in the table below and at a frequency (f) which is an integer multiple of 1.6 MHz. ATIS-0700019 18 With th
39、e following exceptions, called spurious response frequencies: a) 800 MHz: in band, for a maximum of six occurrences (which if grouped shall not exceed three contiguous occurrences per group); 1900 MHz: in band, for a maximum of twelve occurrences (which if grouped shall not exceed three contiguous o
40、ccurrences per group); b) Out of band, for a maximum of 24 occurrences (which if below f0and grouped shall not exceed three contiguous occurrences per group). Where the above performance shall be met when the continuous sine wave signal (f) is set to a level of 70 dBV (emf) (i.e., -43 dBm). Table 5.

The interferer shall have one timeslot active and the frequency shall be at least 2 channels separated from a
43、ny identified spurious response. The transmitted bursts shall be synchronized to but delayed in time between 61 and 86 bit periods relative to the bursts of the wanted signal. NOTE 1: When testing this requirement, a notch filter may be necessary to ensure that the co-channel performance of the rece
44、iver is not compromised.

45、als are simultaneously input to the receiver: A useful signal at frequency fo, 3 dB above the reference sensitivity level as specified in section 6.2; A continuous, static sine wave signal at frequency f1and a level of 70 dBV (emf) (i.e., -43 dBm): ATIS-0700019 20 For 1900 MHz MS and 1900 MHz BTS th
46、is value is relaxed to 64 dBV (emf) (i.e., -49 dBm); Any 148-bits subsequence (O-QAM modulated signal, 144-bit sequence, Short burst at Indoor) of the 511-bits pseudo-random sequence, defined in ITU-T Recommendation O.153 modulating a signal at frequency f2, and a level of 70 dBV (emf) (i.e., -43 dB
47、m): For 1900 MHz MS and 1900 MHz BTS this value is relaxed to 64 dBV (emf) (i.e., -49 dBm); Such that f0= 2f1- f2and |f2-f1| = 800 kHz (|f2-f1| = 6.4 MHz). NOTE 1: For sections 5.2 and 5.3 instead of any 148-bits subsequence of the 511-bits pseudo-random sequence, defined in ITU-T Recommendation O.1
48、53, it is also allowed to use a more random pseudo-random sequence. 5.4 Spurious Emissions The spurious emissions for a BTS receiver, measured in the conditions specified in section 4.3.1, shall be no more than: 2 nW (-57 dBm) in the frequency band 9 kHz - 1 GHz; and 20 nW (-47 dBm) in the frequency
49、 band 1 - 12.75 GHz. NOTE 1: For radiated spurious emissions for the BTS, the specifications currently only apply to the frequency band 30 MHz to 4 GHz. The specification and method of measurement outside this band are under consideration. 6 Transmitter/Receiver Performance In order to assess the error rate performance that is described in this section it is required for a mobile equipment to have a “loop back“ facility by which the equipment transmits back the same i
