A method for determining a slot format of an F-DPCH is disclosed in the present disclosure, including: a Node B using No.0 slot format of the F-DPCH as the slot format for transmitting information over the F-DPCH when detecting that a UE in CELL_FACH state or idle mode is using an E-DCH. An apparatus for determining a slot format of an F-DPCH is also disclosed. The present disclosure ensures that the slot format of the F-DPCH transmitted by the Node B is identical with that of the F-DPCH received by the UE, so that the UE can correctly receive the TPC bits carried on the F-DPCH, and thus the UE can use the TPC bits to implement inner loop power control. Therefore, the Node B can correctly receive the data information transmitted over an E-DPDCH.
