FIELD: radio engineering, communication.
SUBSTANCE: indices starting with 1 correspond to different ZC-sequences and are distributed to cells in such a manner so that indices follow continuously. When a notice about such ZC-sequences is provided from a basic station to user equipment, the initial index specifying the start of continuous indices is combined with the number of distributed sequences, and the notice about them is provided as information of sequences distribution by means of a reporting channel. User equipment and basic station jointly use compliance between ZC-sequences and indices, and user equipment identifies a sequence number suitable for use on the basis of compliance and information of sequences distribution, the notice about which is provided from the basic station.
EFFECT: reduced volume of signals transfer in case of a notice on a ZC-sequence, a sequence of Zadov-Chu or a GCL-sequence distributed for a cell.
