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:

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.

2. The method of claim 1, wherein the first resource index and the second resource index are different.

3. The method of claim 1, wherein the first resource index indicates a first cyclic shift (CS) index and a first resource block (RB), and the second resource index indicates a second CS index and a second RB.

4. The method of claim 3, wherein the transmitting of the information through the first antenna comprises:

generating a first cyclically shifted sequence by cyclically shifting a base sequence by a first CS amount obtained from the first CS index;

generating a first modulated sequence based on the first cyclically shifted sequence and a symbol for the information; and

transmitting the first modulated sequence through the first antenna after mapping the first modulated sequence to the first RB, and the transmitting of the information through the second antenna comprises;

generating a second cyclically shifted sequence by cyclically shifting the base sequence by a second CS amount obtained from the second CS index;

generating a second modulated sequence based on the second cyclically shifted sequence and the symbol for the information; and

transmitting the second modulated sequence through the second antenna after mapping the second modulated sequence to the second RB.

5. The method of claim 4, wherein the first modulated sequence and the second modulated sequence are simultaneously transmitted.

6. The method of claim 1, wherein the first resource index is received from a base station (BS), and the second resource index is acquired from the first resource index.

7. The method of claim 1, wherein each of the first resource index and the second resource index is received from a BS.

8. The method of claim 7, wherein the each of the first resource index and the second resource index is configured by radio resource control (RRC) signaling.

9. The method of claim 3, wherein the first CS index and the second CS index are different, and the first RB and the second RB are the same.

10. The method of claim 3, wherein the first CS index and the second CS index are the same, and the first RB and the second RB are different.

11. The method of claim 1, further comprising:

receiving data,

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

12. The method of claim 11, wherein the first resource index is acquired from a radio resource for a physical control channel to receive the data, and the second resource index is acquired from the first resource index.

13. The method of claim 1, wherein a spatial multiplexing rate of the information is ½

.

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

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

a processor coupled with the RF unit and configured to;

transmit information based on a first resource index through a first antenna; and

transmit the information based on a second resource index through a second antenna.
