FIELD: communications.
SUBSTANCE: invention relates to the field of communications. To achieve the effect, the user equipment comprises a transmitter configured to transmit a random access preamble and information for identifying a terminal to a base station in a two-stage random access procedure; a receiver configured to receive, from said base station, a response signal in a two-stage random access procedure; and a control module configured to consider the contention resolution successful when the information contained in said response signal matches at least a portion of the information for identifying the terminal, wherein the transmitter is configured to distinguish the resource position used to transmit the random access preamble in the two-stage random access procedure , from the resource position used to transmit the random access preamble in the four-way random access procedure.
EFFECT: achieving conflict resolution in the random access procedure when there is a conflict.
