Abstract

A method for uplink transmitting control information from a user equipment in a wireless communication system comprises selecting a specific point among a plurality of points distributed into a symbol space, corresponding to control information, the symbol space including a modulation dimension and a sequence dimension; mapping a signal corresponding to the specific point with a control channel including single carrier-frequency division multiple access (SC-FDMA) symbols; and transmitting the control channel. Preferably, the specific point belongs to the sequence dimension.

Claims

1. A method for transmitting information at a user equipment in a wireless communication system, the method comprising:

transmitting a physical channel using a first frequency resource in a first time slot; and

transmitting the physical channel using a second frequency resource in a second time slot,

wherein if a frequency hopping pattern from the first frequency resource in the first time slot to the second frequency resource in the second time slot matches a predefined pattern, the frequency hopping pattern indicates specific information.

2. The method of claim 1, wherein the specific information includes at least one of acknowledgement/non-acknowledgement (ACK/NACK), a channel quality indicator (CQI), a precoding matrix index (PMI), and a rank indicator (RI).

3. The method of claim 1, wherein the physical channel comprises at least one symbol, a first pilot symbol and a second pilot symbol, and

wherein if a sequence of the first pilot symbol and the second pilot symbol matches a first sequence, the at least one symbol indicates first information, and

if the sequence of the first pilot symbol and the second pilot symbol matches a second sequence, the at least one symbol indicates second information.

4. The method of claim 1, wherein the physical channel is transmitted using one of a plurality of sequences, and each of the plurality of sequences indicates different information.

5. The method of claim 4, wherein the plurality of sequences includes orthogonal sequence, quasi-orthogonal sequence, or pseudo noise (PN) sequence.

6. The method of claim 4, wherein the plurality of sequences includes Zadoff-Chu (ZC) sequence, constant amplitude zero autocorrelation waveform (CAZAC) sequence, Walsh sequence, or discrete Fourier transform (DFT) sequence.

7. The method of claim 1, wherein the physical channel comprises at least one symbol, and the at least one symbol is modulated by one of BPSK (binary phase shift keying), rotated-BPSK, QPSK (quadrature phase shift keying), rotated-QPSK, n-PSK (phase shift keying), or n-QAM (Quadrature Amplitude Modulation), n indicating 8, 16, 32, or 64.

8. The method of claim 1, wherein each of the first frequency resource and the second frequency resource includes at least one subcarrier.

9. The method of claim 1, wherein each of the first frequency resource and the second frequency resource includes at least one subband.

10. The method of claim 1, wherein the first time slot and the second time slot form a subframe.

11. The method of claim 1, wherein the first frequency resource and the second frequency resource are located in different locations in a frequency domain.

12. The method of claim 1, wherein the transmitting of the information is performed within a femto cell or pico cell.

13. A user equipment for transmitting information in a wireless communication system, the user equipment comprising:

a radio frequency (RF) module; and

a processor, wherein the processor is configured to;

transmit a physical channel through the RF module using a first frequency resource in a first time slot, and

transmit the physical channel through the RF module using a second frequency resource in a second time slot,

wherein if a frequency hopping pattern from the first frequency resource in the first time slot to the second frequency resource in the second time slot matches a predefined pattern, the frequency hopping pattern indicates specific information.

14. The user equipment of claim 13, wherein the specific information includes at least one of acknowledgement/non-acknowledgement (ACK/NACK), a channel quality indicator (CQI), a precoding matrix index (PMI), and a rank indicator (RI).
