    Abstract: A method of allocating channels in a user equipment is disclosed. In particular, a method of allocating a plurality of Dedicated Physical Channels (DPCHs) and Enhanced Dedicated Channels (E-DCHs) in a user equipment of a multicode transmission system. The method includes determining whether a High Speed Downlink Shared Channel (HS-DSCH) is configured for the user equipment (UE) and determining a number of codes used by the DPCH and the E-DCH. The method further includes allocating the DPCH and the E-DCH channels to an I branch or a Q branch based on the number of codes used by the DPCH and the E-DCH and the HS-DSCH configuration.

    Abstract: A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.

    Abstract: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.
