Abstract

A method of generating an uplink signal sequence, a user equipment, a base station and a computer-readable storage medium are provided. The method includes: generating an uplink signal sequence r u,v (α) (n) based on r u,v (α) (n)=e jαn r u,v (n), 0≤n<12, where a is configured to distinguish a terminal, an uplink signal base sequence r u,v (n)=e jφ(n)π/4 , where u represents a group number, and v represents an intra-group base sequence number, φ(n)π/4 represents a phase of a base sequence; performing a full traversal of multiple possible phases of the phase φ(n)π/4 on the uplink signal sequence with a length of 12, and selecting a predetermined number of uplink signal sequences with a lowest peak-to-average power ratio and a lowest cross-correlation characteristic.
