A method according to claim 112, wherein said first value of ΔSIRi—compression is defined by: ΔSIRi—compression=10 log(N*Fi/(N*Fi−TGLi)) where TGLi is the gap length in number of slots in the current transmission time interval (TTI) of length Fi frames, and N is the number of slots per frame. 114. A method according to claim 112, wherein said second value of ΔSIRi—compression is defined by: ΔSIRi—compression=10 log(RCF/R), where R is the instantaneous net bit rate during a normal frame and RCF is the instantaneous net bit rate during the current compressed frame. 115. A method according to claim 112, wherein said second value of ΔSIRi—compression is defined by: ΔSIRi—compression=3 dB in the case of compressed mode by reducing the spreading factor by a factor of two.
