hello,
the BCCH TRX emits at maximum power all the time. That is what we know 🙂
It means that, on each timeslot of the BCCH TRX :
1. No power control downlink
2. No downlink DTX
3. Even if there is no data to transmit, the timeslots will be filled with dummy bits.
Other TRX can have PC, DTX, etc.
Regards,
Pix
