PURPOSE: A method for transmitting a DSCH(Downlink Shared Channel) in an IMT-2000(International Mobile Telecommunications-2000) is provided to enable moving UE(User Equipment) to receive DSCH control information from a plurality of drift RNCs(Radio Network Controllers), to which links are set after soft hand-over, as well as from a serving RNC. So that high-speed burst packet data transmitted through the DSCH from the serving RNC can be received without an error. CONSTITUTION: If a soft hand-over to an RNC2(205) is generated due to moving UE(User Equipment) and a link to an RNC1(204) and the RNC2(205) is set, DSCH control information generated in an MAC(Medium Access Control) common/shared channel-1(206) of the RNC1(204) is transmitted to the UE through a DPCH1 of a cell-1 among cells configured in a Node-B1(208), and transmitted to an MAC common/shared channel-2(207) of the RNC2(205) of which a link is newly set with the UE due to the hand-over. The DSCH control information transmitted to the MAC common/shared channel-2(207) is directly delivered to a physical layer of a Node-B2(209) through an Iub interface, and transmitted to the UE through a DPCH2 of a cell-2 among cells configured in the Node-B2(209). The DSCH control information transmitted through the DPCH1 from the MAC common/shared channel-1(206) of the RNC1(204) and the DSCH control information transmitted through the DPCH2 are mutually identical information generated by the MAC common/shared channel-1(206), and are simultaneously transmitted to the UE through more than one RNC to which a link is set with the UE. And the UE receiving the DSCH control information performs combining and decoding for TFCI(Transfer Format Combination Identifier) information of the DPCH1 and the DPCH2.
