Method and apparatus for transmitting uplink signal, and method and apparatus for generating uplink signal in communication system |
摘要 |
When a terminal generates an uplink signal in a communication system, the terminal hops a sequence for differentiating itself from another terminal with time. The terminal generates the uplink signal by multiplying a transmission symbol by a sequence of a transmission time corresponding to the transmission symbol. |

1. A method of transmitting an uplink signal at a terminal of a first user in a wireless communication system, the method comprising:
transmitting a first sequence at a first transmission time, the first sequence being determined by a basic sequence and a first cyclic shift value among a plurality of cyclic shift values including the first cyclic shift value, a second cyclic shift value, a third cyclic shift value, and a fourth cyclic shift value; and transmitting a second sequence at a second transmission time after the first transmission time, the second sequence being determined by the basic sequence and the second cyclic shift value, wherein at a terminal of a second user being different from the first user, a sequence determined by the basic sequence and the third cyclic shift value is transmitted at the first transmission time and a sequence determined by the basic sequence and the fourth cyclic shift value is transmitted at the second transmission time, and wherein a difference between the second cyclic shift value and the first cyclic shift value is different from a difference between the fourth cyclic shift value and the third cyclic shift value when the third cyclic shift value is adjacent to the first cyclic shift value. |
