Abstract

Provided in an embodiment of the present invention are a random access method and a user terminal, the method comprising: acquiring configuration information, the configuration information comprising random access resource configuration information of at least two beams; acquiring signal quality measurement information of the at least two beams; selecting at least one beam according to the signal quality measurement information of the at least two beams; and determining the random access resource of the at least one beam according to the random access resource configuration information of the at least one beam, and initiating random access on the determined random access resource by using the corresponding beam. In this way, the corresponding random access resource is selected according to the signal quality measurement result of each beam, and the corresponding beam is used to initiate random access.

Description

[0001] The application of the present invention is a divisional application of the invention application with the filing date of November 3, 2017, the application number of 201711072301.5, and the invention name of "random access method and user terminal". technical field [0002] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a random access method and a user terminal. Background technique [0003] Various new functions will be introduced in the 5G communication system, such as: master cell group (Master Cell Group, MCG) bearer, secondary cell group (Secondary Cell Group, SCG) bearer, split (Split bearer) bearer or duplicate (Duplicate) bearer And so on, and concepts such as Bandwidth Part (BWP) and beams will also be introduced. Among them, in the 5G communication system, a user terminal may have multiple beams, and in the random access process, the user terminal may only need to initiate random access thro...
