Problems solved by technology

[0003] Generally speaking, the user equipment detects the SSB of the downlink BWP (Band Width Part, bandwidth part) to determine the measurement result of the SSB. However, in some cases, the user equipment does not obtain the measurement result of the SSB for the downlink BWP. It will cause the user equipment to be unable to select the appropriate beam for random access

Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0062] figure 1 It is a schematic flowchart of a random access method shown according to an embodiment of the present disclosure. The random access method shown in this embodiment can be applied to user equipment, such as mobile phones, tablet computers, smart wearable devices (bracelets, watches, helmets, glasses, etc.), and the user equipment can communicate with the base station, for example, based on LTE (Long Term Evolution, long-term evolution) communicates with the base stat...

Abstract

The present disclosure relates to a random access method, including: when initiating random access, determining the measurement results of channel state information measurement reference signals CSI-RS of multiple beams; determining the corresponding target CSI-RS whose measurement results are greater than a preset threshold value determine the target SSB corresponding to the target CSI‑RS; determine the random access preamble and random access opportunity associated with the target SSB; on the target beam based on the random access preamble and the Initiate random access at the above random access opportunity. Based on the embodiments of the present disclosure, the beam can be determined according to the measurement result of CSI-RS, so that it is not necessary to determine the beam according to the measurement result of SSB, thereby preventing the user equipment from being unable to select a suitable The random access of the beams ensures that the user equipment can select beams that meet the requirements.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a random access method, a random access device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In related technologies, when a user equipment initiates random access, it needs to select an appropriate beam, and the selected beam is determined by detecting certain parameters of the beam, for example, when the initiated random access is competitive During random access (CBRA, contention based random access), the user equipment needs to determine whether the signal quality of the beam meets the requirements according to the measurement result of the SSB (Synchronization Signal Block, synchronization signal block). [0003] Generally speaking, the user equipment detects the SSB of the downlink BWP (Band Width Part, bandwidth part) to determine the measurement result of the SSB. However, in some cases, the user equipmen...
