Abstract: Provided is a terminal, for example, user equipment (UE), including a processor and that performs a random access (RA) procedure with a base station, for example, for example, eNodeB, E-UTRAN Node B, or also known as Evolved Node B, and is at least temporarily embodied by the processor. The terminal may be at least temporarily embodied by the processor. The terminal may include a generator configured to generate a preamble sequence using a first sequence corresponding to a first root index based on a preamble index that is randomly selected, and a determiner configured to determine a second root index using the preamble index as an input value of a root index function. Further, the generator may be configured to generate a tag sequence using a second sequence corresponding to the second root index based on a tag index that is randomly selected.
