Abstract

A method for multiplexing a data information stream, including a systematic symbol and a non-systematic symbol, and a control information stream of at least three types in a wireless mobile communication system is disclosed. The method includes mapping the data information stream to a resource area so that the systematic symbol is not mapped to a specific resource area to which the control information stream is mapped, and mapping the control information stream to the specific resource area.

First claim

What is claimed is:

1. A method of transmitting an uplink signal in a wireless communication system, the method comprising:
multiplexing data and rank information (RI); and
transmitting the uplink signal through a plurality of Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, the uplink signal including the multiplexed data and the RI,
wherein the plurality of SC-FDMA symbols includes an SC-FDMA symbol for reference signal, and a first set of two SC-FDMA symbols for the RI, and
wherein each SC-FDMA symbol of the first set of two SC-FDMA symbols for the RI is separated from the SC-FDMA symbol for the reference signal by a respective single SC-FDMA symbol.

2. The method of claim 1 , wherein each of the respective single SC-FDMA symbols are contiguous with the SC-FDMA symbol for the reference signal and comprise a second set of two SC-FDMA symbols reserved for first control information different from the RI.

3. The method of claim 2 , wherein, if the uplink signal further includes the first control information, the data on the second set of two SC-FDMA symbols is punctured by the first control information.

4. The method of claim 1 , wherein the SC-FDMA symbol for the reference signal includes 4 th SC-FDMA symbol in the subframe.

5. The method of claim 4 , wherein the first set of two SC-FDMA symbols for the RI includes 2 nd and 6 th SC-FDMA symbols in the subframe.

6. The method of claim 1 , wherein the uplink signal is transmitted through a Physical Uplink Shared Channel (PUSCH).

7. An apparatus for use in a wireless communication system, the apparatus comprising:
a device configured to multiplex data and rank information (RI); and
a device configured to transmit an uplink signal including the multiplexed data and RI via a plurality of Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols in a subframe,
wherein the plurality of SC-FDMA symbols includes an SC-FDMA symbol for reference signal, and a first set of two SC-FDMA symbols for the RI, and
wherein each SC-FDMA symbol of the first set of two SC-FDMA symbols for the RI is separated from the SC-FDMA symbol for the reference signal by a respective single SC-FDMA symbol.

8. The apparatus of claim 7 , wherein each of the respective single SC-FDMA symbols are contiguous with the SC-FDMA symbol for the reference signal and comprise a second set of two SC-FDMA symbols reserved for first control information different from the RI.

9. The apparatus of claim 8 , wherein, if the uplink signal further includes the first control information, the data on the second set of two SC-FDMA symbols is punctured by the first control information.

10. The apparatus of claim 7 , wherein the SC-FDMA symbol for the reference signal includes 4 th SC-FDMA symbol in the subframe.

11. The apparatus of claim 10 , wherein the first set of two SC-FDMA symbols for the RI includes 2 nd and 6 th SC-FDMA symbols in the subframe.

12. The apparatus of claim 7 , wherein the uplink signal is transmitted through a Physical Uplink Shared Channel (PUSCH).
