FIELD: radio engineering, communication.
SUBSTANCE: cyclic shift of a reference signal is quantized in the form of a combination of a cell-specific cyclic shift and a result of a pseudo-random spasmodic frequency tuning, and broadcasting transfer of indication of a cell-specific cyclic shift is performed in a cell. The cyclic shift is quantised in the form of an operation of taking a module of a sum of a cell-specific cyclic shift, a result of pseudo-random spasmodic frequency tuning and a user-specific cyclic shift, in this case indication of a user-specific cyclic shift is sent when assigning resources to an uplink, and the user sends its cyclically shifted reference signal in the assigned resource of the uplink by assignment of uplink resources.
EFFECT: improved noise immunity.
