Abstract

A method and an apparatus of transmitting information in a wireless communication system are provided. The method includes transmitting information based on a first resource index through a first antenna and transmitting the information based on a second resource index through a second antenna.

Claims

1. A method of transmitting information in a wireless communication system, carried in a transmitter, the method comprising:

obtaining a first physical uplink control channel (PUCCH) resource for a first antenna port and a second PUCCH resource for a second antenna port, the first antenna port and the second antenna port being different, and the first PUCCH resource and the second PUCCH resource being different;

transmitting information on a PUCCH using a first orthogonal code (OC), a first cyclic shift (CS) and a first resource block (RB) through the first antenna port in a single carrier frequency division multiple access (SC-FDMA) symbol in time domain, wherein the first PUCCH resource includes the first OC, the first CS and the first RB; and

transmitting the information on the PUCCH using a second OC, a second CS and a second RB through the second antenna port in the SC-FDMA symbol in time domain,

wherein the second PUCCH resource includes the second OC, the second CS and the second RB,

wherein the information on the PUCCH comprises a plurality of symbols, and

wherein the transmission of each symbol through the first antenna port using the first PUCCH resource overlaps in time with the transmission of the same symbol through the second antenna port using the second PUCCH resource.

2. The method of claim 1, wherein the format of the first PUCCH resource and the second PUCCH resource is PUCCH format 1/1a/1b.

3. The method of claim 1, wherein the first PUCCH resource and the second PUCCH resource are obtained from a base station (BS).

4. The method of claim 3, wherein the first PUCCH resource and the PUCCH second resource are configured by radio resource control (RRC) signaling.

5. The method of claim 1, wherein the transmitting of the information through the first antenna port comprises:

generating a first modulated sequence by multiplying a first cyclically shifted sequence, which is shifted based on the first CS, and the control information;

generating a first spread sequence by multiplying the first modulated sequence and the first OC; and

transmitting the first spread sequence which is mapped to the first RB through the first antenna port, and

wherein the transmitting of the information through the second antenna port comprises;

generating a second modulated sequence by multiplying a second cyclically shifted sequence, which is shifted based on the second CS, and the control information;

generating a second spread sequence by multiplying the second modulated sequence and the second OC; and

transmitting the second spread sequence which is mapped to the second RB through the second antenna port.

6. The method of claim 1, further comprising:

receiving data,

wherein the information includes control information, and the control information includes a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/not-acknowledgement (NACK) for the data.

7. The method of claim 6, wherein the first PUCCH resource is obtained from a first control channel element (CCE) index used for a physical downlink control channel (PDCCH) corresponding to the data.

8. The method of claim 1, wherein the second PUCCH resource is obtained from the first PUCCH resource.

9. The method of claim 1, wherein the plurality of symbols comprise control information symbols and reference signal symbols.

10. An apparatus for a wireless communication, the apparatus comprising:

a radio frequency (RF) unit transmitting and/or receiving a radio signal; and

obtain a first physical uplink control channel (PUCCH) resource for a first antenna port and a second PUCCH resource for a second antenna port, the first antenna port and the second antenna port being different, and the first PUCCH resource and the second PUCCH resource being different;

transmit information on a PUCCH using a first orthogonal code (OC), a first cyclic shift (CS) and a first resource block (RB) through the first antenna port in a single carrier frequency division multiple access (SC-FDMA) symbol in time domain, wherein the first PUCCH resource includes the first OC, the first CS and the first RB; and

transmit the information on the PUCCH using a second OC, a second CS and a second RB through the second antenna port in the SC-FDMA symbol in time domain,

wherein the second PUCCH resource includes the second OC, the second CS and the second RB,

wherein the information on the PUCCH comprises a plurality of symbols, and

wherein the transmission of each symbol through the first antenna port using the first PUCCH resource overlaps in time with the transmission of the same symbol through the second antenna port using the second PUCCH resource.
