FIELD: communication.
SUBSTANCE: invention relates to a wireless mobile communication system. More particularly, the invention relates to a method for determining an initial state in a DAS which includes receiving a value through high-level signalling and determining an initial state based on the value, in which the value includes a value in which is set an initial state of a scrambling sequence, which differs according to a transmission point.
EFFECT: technical result consists in proper distribution of initial state, required for generation of a scrambling sequence for a PDSCH DMRS to achieve effective interference randomization in a Distributed Antenna System (DAS), where there are multiple transmission points having the same cell ID.
