Patent ID: 7251266

Claim:
A method for determining amplification factors of a data channel and of a control channel of a data transmission system, the method comprising the steps of: performing data transmission in one of a normal mode and a compression mode; calculating a nominal ratio (A j ) in the normal mode from signaled reference amplification factors (β c,ref , β d,ref ); determining amplification factors (β c,j , β d,j ) from the nominal ratio via one of rounding and discretization; calculating a corrected nominal ratio (A c,j ) from the calculated nominal ratio (A j ) in the compression mode without using the amplification factors (β c,j , β d,j ) determined from the nominal ratio via one of rounding and discretization; and determining amplification factors (β c,C,j , β d,C,j ) from the corrected nominal ratio via one of rounding and discretization, wherein the amplification factors are used for avoiding inaccurate power settings in the data transmission system.
