Transmitting spread signal in communication system
First Claim
1. A method for communicating Acknowledgement/Negative acknowledgement (ACK/NACK) information in a mobile communication system, the method comprising:
- transmitting, by a base station, a first signal including first spread ACK/NACK information and second spread ACK/NACK information on a first set of four available neighboring subcarriers in an orthogonal frequency division multiplexing (OFDM) symbol, wherein the first spread ACK/NACK information and the second spread ACK/NACK information are coded on the first set of four available neighboring subcarriers as shown in Table 1;
receiving, by a terminal, the first signal including the first spread ACK/NACK information and the second spread ACK/NACK information on the first set of four available neighboring subcarriers;
transmitting, by the base station, a second signal including third spread ACK/NACK information and fourth spread ACK/NACK information on a second set of four available neighboring subcarriers in an OFDM symbol, wherein the third spread ACK/NACK information and the fourth spread ACK/NACK information are coded on the second set of four available neighboring subcarriers as shown in Table 2; and
receiving, by the terminal, the second signal including the third spread ACK/NACK information and the fourth spread ACK/NACK information on the second set of four available neighboring subcarriers,

Abstract
A method for receiving Acknowledgement/Negative acknowledgement (ACK/NACK) information in a mobile communication system includes receiving a first signal including first spread ACK/NACK information and second spread ACK/NACK information from a first antenna set of a transmitting end in an orthogonal frequency division multiplexing (OFDM) symbol; receiving a second signal including third spread ACK/NACK information and fourth spread ACK/NACK information from a second antenna set of the transmitting end in an OFDM symbol; and de-spreading at least the first and third spread ACK/NACK information or the second and fourth spread ACK/NACK information for identifying the ACK/NACK information.
