i don’t understand how it would eliminate the interference, can you explain further ?
anyway, the TRX that carries the BCCH timeslot will always transmit a dummy signal at full power on all the timeslots, even if there is no data to transmit. So blocking 5 TS just means that the uplink TS will not be used. The 5 TS in downlink will be used.
In IDLE mode, the C/I will have an impact : the MS cannot decode the downlink system information messages and the downlink paging messages, or the BTS cannot decode the uplink channel request (RACH) or uplink HO ACCESS.
