TRANSMITTER, RECEIVER, TRANSMISSION METHOD AND RECEPTION METHOD Russian patent published in 2015 - IPC H04J99/00 

FIELD: radio engineering, communication.

SUBSTANCE: provided transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signalling for notifying the cyclic shift value. In the transmitter, with regard to each basic shift value candidate group having a basic shift value from 0 to N-1, a transmission control unit (206) specifies the actual shift value imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port. The specification is performed based on a table in which cyclic shift value candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift value candidates for shift value X, the table differentiates between an offset pattern comprising offset values for cyclic shift value candidates corresponding to each antenna port and an offset pattern corresponding to basic shift value candidates of X+N/2.

EFFECT: high communication reliability.
