Patent ID: 7792212

Claim:
A method for transmitting signals to a base station by setting a cyclic shift value to be applied to a given sequence against an effect of a high Doppler frequency higher than a predetermined value at a user equipment (UE), the method comprising: acquiring a first variable (d u ) of a cyclic shift corresponding to a Doppler shift of one subcarrier spacing by using a root index (u) of the given sequence; acquiring secondary variables using the first variable (d u ), wherein the secondary variables comprise a number (G) of groups generated by grouping the given sequence, a length (S) each group of the groups, and a number (P) of applicable cyclic shift values for each group of the groups; setting the cyclic shift value to be applied to the given sequence according to the secondary variables; and applying the set cyclic shift value to the given sequence; and transmitting the given sequence which has been applied to the set cyclic shift value to the base station.
