According to embodiments of the invention, the method of Fig. 1 also comprises: when selected transformat is the first transformat, E-TFCI corresponding for current transmitting uplink data block waiting for transmission is obtained offset value relative to said reference value as the first indication information by subscriber equipment, wherein in 120, subscriber equipment is according to the first transformat, and the control information of the first indication information is carried in transmission on the e-dpcch.In other words, UE transmits the deviator of E-TFCI corresponding to transmitting uplink data block relative to fiducial value on e_E-DPCCH.

Such as, in 120, UE can search the E-TFCI corresponding with current transmitting uplink data block waiting for transmission according to the size of current transmitting uplink data block waiting for transmission in traditional E-TFCI shows, and this E-TFCI is deducted said reference value obtains above-mentioned offset value.The fiducial value of business can pre-set, or can be mean value or the weighted average of the E-TFCI that all transmitting uplink data blocks of this business are corresponding.Or fiducial value is the up-to-date E-TFCI sent by up-to-date second transformat E-DPCCH, or by the upper E-TFCI sent of the Transmission Time Interval of making an appointment or configure (TTI) as fiducial value.In other words, under first transformat of E-DPCCH, control information only carries E-TFCI deviator (E-TFCI_Offset).In other words, this offset value is near fiducial value, and this offset value just can be, also can be negative, under the first transformat, can encode to offset value.

Alternatively, offset value here, except can be understood as the deviator of E-TFCI, without loss of generality, it is also understood that the offset value into sending size of data (such as, transmission block size).Under the first transformat, can encode to this offset value.
