Abstract
Embodiments of this application provide a communication method and a communications apparatus. The method includes: receiving identification information of N beams of a target cell and random access channel configurations of M beams in the N beams, where N and M are positive integers; and determining a beam for accessing based on signal quality or signal strength of L beams in the N beams, the identification information of the N beams, and the random access channel configurations of the M beams, where L is a nonnegative integer.
Claims30
A method, comprising:
- receiving, by a first network device from a second network device, identification information of N beams of a target cell and random access channel configurations corresponding to M beams in the N beams, wherein N and M are positive integers;
- and
- sending, by the first network device, the identification information of the N beams and the random access channel configurations corresponding to the M beams to a terminal.
A method, comprising:
- receiving, by a terminal, identification information of N beams of a target cell and random access channel configurations corresponding to M beams in the N beams, wherein N and M are positive integers, and each random access channel configuration of the random access channel configurations of the M beams comprises a respective preamble index and a respective time-frequency resource configuration;
- and
- when the M beams comprise a first beam whose signal strength is greater than or equal to a first beam signal strength threshold, determining, by the terminal, to use the first beam whose signal strength is greater than or equal to the first beam signal strength threshold from the M beams to access the target cell.
An apparatus, comprising:
- a first circuit, configured to
- receive identification information of N beams of a target cell and random access channel configurations corresponding to M beams in the N beams, wherein N and M are positive integers, and each random access channel configuration of the random access channel configurations corresponding to M beams comprises a respective preamble index and a respective time-frequency resource configuration;
- and
- a second circuit, configured to:
- when the M beams comprise a first beam whose signal strength is greater than or equal to a first beam signal strength threshold, determine to use the first beam whose signal strength is greater than or equal to the first beam signal strength threshold from the M beams to access the target cell.
A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program to be executed by a processor, the program including instructions for:
- receiving identification information of N beams of a target cell and random access channel configurations corresponding to M beams in the N beams, wherein N and M are positive integers, and each random access channel configuration of the random access channel configurations corresponding to the M beams comprises a respective preamble index and a respective time-frequency resource configuration;
- and
- when the M beams comprise a first beam whose signal strength is greater than or equal to a first beam signal strength threshold, determining to use the first beam whose signal strength is greater than or equal to the first beam signal strength threshold from the M beams to access the target cell.
