Abstract

The invention provides a random access method, equipment and a terminal, relates to the technical field of communication, and aims to solve the problem that the communication success rate between theterminal and a network side is low due to the fact that random access resources cannot be configured on a BWP of the terminal in the prior art. The method comprises: acquiring random access configuration information, wherein the random access configuration information comprises random access resources corresponding to BWPs; Obtaining a target random access resource corresponding to a BWP currentlyactivated by the terminal according to the random access configuration information; And using the target random access resource to initiate a random access process. By utilizing the embodiment of theinvention, the communication success rate between the terminal and the network side can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a random access (Random Access, RA) method, device and terminal. Background technique [0002] In the 5G system, the terminal may only support a relatively small working bandwidth (such as 5MHz), while a cell on the network side will support a relatively large bandwidth (such as 100MHz), and the small bandwidth part of the terminal's work in the large bandwidth is It is called the bandwidth part (Bandwidth Part, BWP). From the perspective of terminal configuration, for different terminal functions, the BWP can be used as a BWP in one cell or under one cell. [0003] The network side can configure the terminal to have one or more BWPs, and change the working BWP of the terminal by activating or deactivating the BWP. Usually, the network side will configure a default BWP (default BWP). When the terminal works in other BWPs in the cell, the network side can config...
