Patent ID: 8462760

Claim:
A method for controlling signal transmission, comprising: determining a first reference variable, n 1 , according to the number of transition points from downlink to uplink in a wireless frame of a system, N SP , and a system frame number, n f ; determining a second reference variable, n 2 , according to the number of transition points from downlink to uplink in said wireless frame, N SP , and a time slot number, n s ; determining a third reference variable, n 3 , according to a sub-frame offset of a signal, T offset , and a maximum sub-frame offset of said signal, T offset — max ; and determining transmission times of said signal, n SRS , according to the first reference variable, n 1 , the second reference variable, n 2 , and the third reference variable, n 3 , using the following formula: n SRS =n 1 +n 2 +n 3 wherein n 1 =2N sp n f , n 2 = 2 ⁢ ( N SP - 1 ) ⁢ ⌊ n s 10 ⌋ , n 3 = ⌊ T offset T offset_max ⌋ , and N SP , n f , n s and T offset are non-negative integers.
