one timeslot = 1 timeslot in UL (using lower frequency band) + 1 TS in DL (using upper frequency band)
when you say frequency ARFCN “1” is allocated to one TRX, actually it means that the TRX will transmit in a DL frequency 935.2 MHz and receive on a UL frequency 890.2 MHz .
that’s why it’s full duplex.
that’s the same for Abis links : one TS actually describes 2 TS in opposite directions.
