    摘要: A method for a user equipment to transmit a random access preamble sequence to a base station includes transmitting the random access preamble sequence generated from a Constant Amplitude Zero Auto Correlation (CAZAC) sequence to the base station, wherein the CAZAC sequence is cyclic shifted according to one of applicable cyclic shift values defined considering a value (M) representing a Doppler shift of one subcarrier spacing and a cyclic shift unit length (T), and wherein when the value (M) meets a condition of ‘P*T≦M
