Abstract

The invention provides a random access method, a mobile terminal and a network device, and aims to solve the problem that there is no relevant scheme about how to carry out random access according tomultiple BWPs (Bandwidth Part) of a mobile terminal in the process of random access. The method of the invention includes the following steps: acquiring the resource allocation information of BWP configured or predetermined by a network device; and sending or receiving random access messages in the process of random access according to the BWPs indicated by the resource allocation information of BWP. Different BWPs can be configured or defined for different random access messages, so that a mobile terminal can be switched to different BWPs to send or receive different random access messages inthe process of random access. The problem on how to carry out random access according to multiple BWPs of a mobile terminal is solved, and the resource utilization rate of the system is improved. Moreover, a mobile terminal is not affected by the activation or deactivation of BWPs in the process of random access, and it is ensured that a mobile terminal can uninterruptedly execute the random access process.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a random access method, a mobile terminal and network equipment. Background technique [0002] In a 5G system, a mobile 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). Is the bandwidth part (Bandwidth Part, referred to as BWP). For different mobile terminal functions, the network side can configure one or more BWPs for the mobile terminal, and change the BWP that the mobile terminal can work by activating or deactivating the BWP. However, in the existing random access process, there is no relevant solution on how to perform random access according to multiple BWPs of the mobile terminal. Contents of the invention [0003] Embodiments of the present invention provide a random access method, a mobile terminal and a network device...
