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.

Abstract: Provided are a method and device for performing data transmission capable of solving a problem in the prior art in which if a user equipment unit needs to perform transmission with a network, the user equipment unit needs to perform a cell switching process to enter another cell, and this results in higher signaling overheads for a terminal. In an embodiment of the invention, a new connected state is different from an idle state and a connected state. In the new connected state, a terminal can perform data transmission with a network side device. Moreover, after the terminal has moved to a coverage of another cell from a coverage of a cell currently accessed by it, the terminal can move to the new cell by means of cell reselection without performing a cell switching process.
