the timeslot hops to another TRX, but the content of the timeslot remains as it was before :
if i have a GMSK ts on TRX 2 / TS 7, and then there is a hopping to TRX 3 / TS 7 -> this is still GMSK timeslot. You’re talking about BBH, right ?
as i said, you’re making things too complicated. A TRX will work with different modulations (GMSK / 8PSK) for different timselots, within different TDMA frames.
