CROSS REFERENCE OF RELATED APPLICATION PROGRAM

The present application is the U.S. national phase of PCT Application PCT/CN2018/109806 filed on Oct. 11, 2018, which claims a priority of Chinese patent application No. 201711072301.5 filed on Nov. 3, 2017, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of communications technologies, and in particular to a random access method and a user equipment.

BACKGROUND

Compared with the mobile communication system in the related art, various new functions will be introduced in the 5G communication system, such as Master Cell Group (MCG) bearer, Secondary Cell Group (SCG) bearer, Split Bearer, or Duplicate Bearer, and the concepts of Bandwidth Part (BWP) and Beam will also be introduced. In the 5G communication system, a user equipment may have multiple beams, and in a random access process, the user equipment may need to initiate a random access through only a part of the beams, for example, initiating a random access through one beam. In this way, how to select a beam to initiate a random access process is a technical issue that needs to be solved immediately at present.

SUMMARY

In a first aspect, a random access method is provided in an embodiment of the present disclosure, including:

acquiring configuration information, where the configuration information includes random access resource configuration information of at least two beams;

acquiring signal quality measurement result information of the at least two beams;

selecting at least one beam according to the signal quality measurement result information of the at least two beams; and

determining a 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 a random access on the determined random access resource through the at least one beam.

In a second aspect, a User Equipment (UE) is provided in an embodiment of the present disclosure, including:

a first acquiring module, configured to acquire configuration information, where the configuration information includes random access resource configuration information of at least two beams;

a second acquiring module, configured to acquire signal quality measurement result information of the at least two beams;

a selecting module, configured to select at least one beam according to the signal quality measurement result information of the at least two beams; and

a random access module, configured to determine a random access resource of the at least one beam according to the random access resource configuration information of the at least one beam, and initiate a random access on the determined random access resource through the at least one beam.

In a third aspect, a user terminal is further provided in an embodiment of the present disclosure, including a memory, a processor and a program stored in the memory and executable on the processor, where the program is executed by the processor to perform the random access method hereinabove.

In a fourth aspect, a computer-readable storage medium is further provided in an embodiment of the present disclosure, where a program is stored in the computer-readable storage medium, and the program is executed by a processor to perform the random access method hereinabove.
