Abstract: User equipment (UE) that includes a processor and that executes a random access procedure with a base station (E-UTRAN Node B (eNodeB), also known as Evolved Node B) is provided. The UE can at least temporarily be embodied by the processor. The UE may comprise: a determination unit for determining a message size that can be transmitted and that corresponds to a physical random access channel according to an assigned communication method with the base station; a calculation unit for configuring a message to correspond to the message size and for respectively calculating a preamble index and at least one message index from the message; and an encoder for providing respective encoding of the preamble index and the at least one message index, and transmitting the same to the base station.
