Problems solved by technology

[0003] In the future, the 5G system will often work in the high frequency band, the beam quality will be unstable, and the order in which the beams corresponding to the dedicated random access resource and the common random access resource arrive at the UE is uncertain. If the UE always waits for the beam corresponding to the dedicated random access resource, Then it is likely to miss the beam corresponding to the public random access resource with better quality, which will cause the UE to spend a long time in the random access process of the target cell.

Embodiment Construction

[0065] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0066] Embodiments of the present invention provide a method for using random access resources, a network side device and a user terminal, which can accelerate a UE's access process in a target cell.

[0067] An embodiment of the present invention provides a method for using random access resources, which is applied to network side equipment, such as figure 1 As shown, the method includes:

[0068] Step 101: Send a handover command to the user terminal, where the handover command carries the quality threshold of the beam corresponding to the common random access resource.

[0069] Further, the quality threshold is at least one of the following:

[0070] RSRP (Reference Signal Receiving Power, reference signal receiving power) thresho...

Abstract

The invention provides a random access resource using method, network side equipment and a user terminal, and belongs to the technical field of wireless communication. The random access resource usingmethod applied to the user terminal comprises the step of initiating random access by using a public random access resource when the detected quality of a beam corresponding to the public random access resource exceeds a preset quality threshold. According to the technical scheme of the invention, the access process of the UE in the target cell can be accelerated.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for using random access resources, network side equipment and user terminals. Background technique [0002] During the handover process of the 5G NR (New Radio, new air interface) system, the target base station can configure the dedicated resources and / or public resources used by the target base station to initiate random access for UE (User Equipment, user equipment) in the handover command, And the quality threshold of the beam used to initiate random access. If the quality of the beam corresponding to the dedicated resource of the UE is higher than the threshold requirement, then the UE should preferentially use the dedicated resource instead of the common resource, that is, the UE preferentially uses the beam corresponding to the dedicated random access resource not lower than the quality threshold to initiate random access . [0003] In the...
