Problems solved by technology

[0006] Since the random access process supported by 5G does not optimize the aforementioned two-step random access process, for the two-step random access process, the configuration of the existing random access process and the configuration of the uplink shared channel will be reused. will reduce the efficiency of the system

Abstract

The invention provides a random access method. The random access method comprises the following steps of: acquiring configuration information; transmitting a first message containing a leader sequenceand an uplink shared channel according to the configuration information; and receiving a second message containing conflict resolution information from the base station.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a random access method, user equipment and base station. Background technique [0002] The random access process is an important way for the terminal in the system to establish a connection with the base station. In 5G, according to whether the same access resources (including random access channel time-frequency resources and random access preamble resources) are shared by multiple terminals, they can be divided into contention-based random access process and contention-free random access process . Among them, the contention-based random access process is mainly used for initial access. The terminal in the connected state is out of sync but has uplink data to send, cell switching, or beam failure recovery and other application scenarios; and contention-free random access The process is mainly used in application scenarios such as uplink asynchronou...
