A first node receives a first signaling group, the first signaling group being used to indicate a first signature sequence group and a second signature sequence group; transmits a first signature sequence in a first time interval; and transmits a second characteristic sequence in a second time interval; whether the first signature sequence belongs to the first signature sequence group or the second signature sequence group is used for selecting the second signature sequence; any signature sequence in the first signature sequence group is associated with a shared channel resource unit in a first period. The present application avoids the situation where the first node persistently selects random access preambles without being associated with a shared channel resource unit, thus ensuring that the requirement on access delay for UE is satisfied.
