3-2 Transmitter Specification

3-2-1 Power

3-2-2 Power Ramping Time Level

The power-time template requirements for mobile

stations also apply to base stations. The only

difference is that, in the base station case, no short

burst (random access) exists. To measure the

template, the base station has to be operated in its

bursting mode. This test cannot be performed on the

base channel, since a base station has to transmit

continuously in all time slots. In most cases, an

additional channel besides the base channel has to

be activated or the transmitter under test is not

considered to be configured as a base channel

transmitter. The average peak power from the

previous part of the test is used as a reference. The

time reference is provided by the training sequence

in the middle of the burst. The template has to meet

the requirements of Fig. 6. Again, the noise level of -

70 dBc is dependent on the actual transmitted

power level. If this level is below -36 dBm, the

absolute level applies. The template is usually

evaluated along with the peak power level.
