Abstract:
The present invention relates to the field of radio frequency communications, and in particular, to a random access method and equipment. The invention resolves an issue of being unable to apply a random access process to a situation having strict latency requirement, owing to a longer latency during the random access process. In one embodiment of the invention, the method comprises: transmitting, by a user equipment (UE) and according to a resource in a resource pool dedicated to a contention-based random access procedure, UE identification information to a neighborhood; and if receiving a contention resolution message from the neighborhood, determining, by the UE and according to the contention resolution message, whether the contention-based random access procedure is successful. The random access procedure disclosed by present invention further comprises: determining, by the UE and according to second resource information, a resource dedicated to uplink transmission in a target neighborhood; and accessing, according to the resource dedicated to uplink transmission, into the target neighborhood. The embodiments of the invention decreases timing latency of the random access procedure by reducing interaction steps during the random access procedure, and as a consequence, the embodiments can be applied to the situation having the strict latency requirement.
