    Can somebody help me. If there is some kind of documentation or links in internet I will be very grateful.

    Hi Toma IRC sounds like interference reject combining. But this is a feature for improvemento the uplink interference and therefore improvement of drop call. We have this feature in our GSM network. Never eard of it for UMTS (i’ll check if exist in 3g and I’ll let you know). Dyma is also a gsm feature
