Method and device for controlling signal transmission
The method for controlling signal transmission includes: determining the first reference variable according to the number of transition points from downlink to uplink in a wireless frame of the system and the system frame number (S 502 ); determining the second reference variable according to the number of transition points from downlink to uplink in a wireless frame and the time slot number (S 504 ); determining the third reference variable according to the sub-frame offset of the signal (S 506 ); and determining signal transmission times according to the first reference variable, the second reference variable and the third reference variable, so as to control the signal transmission (S 508 ).
