Abstract

Claims (30)

1. A method for transmitting a signal including data and control information in a subframe in a wireless mobile communication system, the method including:

writing a first vector sequence of rank information onto a first set of four columns of a matrix starting from the last row of the matrix and moving upwards at a channel interleaver when the rank information is transmitted in the subframe;

generating a second vector sequence, via a data and control multiplexing unit, by multiplexing Channel Quality Information (CQI) or Precoding Matrix Index (PMI) with the data information of coded bits of an Uplink Shared Channel (UL-SCH);

writing the second vector sequence onto the matrix starting from row ‘0’ downwards at the channel interleaver,

wherein, in each row, the writing is performed rightwards starting from column ‘0’ skipping matrix entries that are already occupied;

writing a third vector sequence of Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information onto a second set of four columns of the matrix starting from the last row and moving upwards at the channel interleaver when the HARQ-ACK information is transmitted in the subframe,

wherein the second set is different from the first set; and transmitting output of the channel interleaver, wherein the output is a bit sequence read out column by column from the matrix.

2. The method of claim 1 , wherein, each vector element of each of the first vector sequence, the second vector sequence, and the third vector sequence is comprised of Modulation Order (Qm) bits, each vector element of each of the first vector sequence, the second vector sequence, and the third vector sequence is written onto a corresponding column of the matrix by a set of Qm rows, and the number of columns of the matrix is equal to the number of Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols per subframe for Physical Uplink Control Channel (PUSCH) transmission.

3. The method of claim 2 , wherein, column indexes corresponding to the first set of four columns are ‘1’, ‘4’, ‘7’, and ‘10’, and column indexes corresponding to the second set of four columns are ‘2’, ‘3’, ‘8’, and ‘9’ when the signal is transmitted according to a normal CP (cyclic prefix) configuration.

4. The method of claim 2 , wherein, column indexes corresponding to the first set of four columns are ‘0’, ‘3’, ‘5’, and ‘8’, and column indexes corresponding to the second set of four columns are ‘1’, ‘2’, ‘6’, and ‘7’ when the signal is transmitted according to an extended CP configuration.

vector elements of each of the first vector sequence, the second vector sequence, and the third vector sequence are sequentially written starting from vector index ‘0’ in an increasing vector index order.

6. The method of claim 1 , wherein,

the bit sequence read out column by column from the matrix is used to generate symbols inputted to a resource element mapper.

7. A wideband wireless mobile communication device configured to transmit a signal including data and control information in a subframe, the wireless mobile communication device comprising:

a data and control multiplexing unit for multiplexing Channel Quality Information (CQI) or Precoding Matrix Index (PMI) CQI/PMI with data information of coded bits of a of an Uplink Shared Channel (UL-SCH)UL-SCH; and

write the first vector sequence onto a first set of four columns of the matrix starting from the last row of the matrix and moving upwards when the rank information is transmitted in the subframe,

write the second vector sequence onto the matrix starting from row ‘0’ downwards, wherein, in each row, the writing is performed starting from column ‘0’ rightwards skipping matrix entries that are already occupied, and

write the third vector sequence onto a second set of four columns of the matrix starting from the last row and moving upwards, wherein the second set is different from the first set when the HARQ-ACK information is transmitted in the subframe.

8. The device of claim 7 , wherein,
