Disclosed are a method for transferring control information, a transmitting device and a receiving device, the method includes that: a transmitting end orderly selects an element y n or two elements y 2 m -1 , y 2 m , from a sequence Y to be modulated corresponding to control information B newly added, wherein, n=1...L, L‰¤N, m=1...L/2, L is a even number and meets L‰¤2N, then it selects pairing elements x 2 p -1 , x 2 p , from a sequence X to be modulated corresponding to related control information A, and groups y n or y 2 m -1 , y 2 m and the x 2 p -1 , x 2 p , into an element group ( x 2 p -1 , x 2 p , y n ) or ( x 2 p -1 , x 2 p , y 2 m -1 , y 2 m ) and maps ( x 2 p -1 , x 2 p , y n ) or ( x 2 p -1 , x 2 p , y 2 m -1 , y 2 m ) as specified constellation points of a specified constellation diagram, and takes the constellation points as modulation symbols that one-to-one correspond to ( x 2 p -1 , x 2 p , y n ) or ( x 2 p -1 , x 2 p , y 2 m -1 , y 2 m ) wherein, p ˆˆ[1, N ]; it takes each two elements in the elements of the sequence X which are not used for pairing as an element group to perform QPSK modulation, modulating into QPSK modulation symbols; and it maps the constellation points and the QPSK modulation symbols to part of or all resources occupied by a corresponding control channel to be transmitted. |
