Abstract
A random access method, a terminal and a computer-readable storage medium are provided, related to the field of communication technologies. The random access method applied to a terminal includes: sending, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam; monitoring and receiving, within a preset RAR time window, at least one RAR message sent by the base station.
Claims18
A random access method, applied to a terminal and comprising:
- sending, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam;
- monitoring and receiving, within a preset Random Access Response (RAR) time window, at least one RAR message sent by the base station;
- wherein the sending, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam comprises:
- sending, to the base station, the random access preamble on the second beam, before a RAR time window corresponding to the random access preamble sending by the first beam expires;
- wherein in the case that the random access preamble is sent to the base station on the second beam, the random access method further comprises:
- stopping a random access process on the first beam;
- wherein the monitoring and receiving, within the preset RAR time window, at least one RAR message sent by the base station comprises:
- stopping monitoring the RAR message sent by the base station, within the RAR time window corresponding to the random access preamble sending by the first beam, and
- monitoring and receiving the RAR message which is sent by the base station and corresponding to the second beam on which the random access preamble is sent for the last time, within a RAR time window corresponding to the second beam on which the random access preamble is sent for the last time.

A terminal, comprising:
- a memory, a processor and a computer program stored in the memory and executable by the processor, wherein the computer program is executed by the processor to:
- send, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam;
- monitor and receive, within a preset Random Access Response (RAR) time window, at least one RAR message sent by the base station;
- wherein the computer program is executed by the processor to:
- send to the base station the random access preamble on the second beam, before a RAR time window corresponding to the random access preamble sending by the first beam expires;
- wherein the random access preamble is sent to the base station on the second beam, the computer program is executed by the processor to:
- stop a random access process on the first beam;
- wherein the computer program is executed by the processor to:
- stop monitoring the RAR message sent by the base station, within the RAR time window corresponding to the random access preamble sending by the first beam, and
- monitor and receive the RAR message which is sent by the base station and corresponding to the second beam on which the random access preamble is sent for the last time, within a RAR time window corresponding to the second beam on which the random access preamble is sent for the last time.

A non-transitory computer-readable storage medium, wherein a computer program is stored in the computer-readable storage medium, and the computer program is executed by a processor to perform:
- sending, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam;
- monitoring and receiving, within a preset Random Access Response (RAR) time window, at least one RAR message sent by the base station;
- wherein the sending, to a base station, a random access preamble on a second beam, subsequent to sending a random access preamble on a first beam comprises:
- sending, to the base station, the random access preamble on the second beam, before a RAR time window corresponding to the random access preamble sending by the first beam expires;
- wherein in the case that the random access preamble is sent to the base station on the second beam, the computer program is executed by the processor to perform:
- stopping a random access process on the first beam;
- wherein the monitoring and receiving, within the preset RAR time window, at least one RAR message sent by the base station comprises:
- stopping monitoring the RAR message sent by the base station, within the RAR time window corresponding to the random access preamble sending by the first beam, and
- monitoring and receiving the RAR message which is sent by the base station and corresponding to the second beam on which the random access preamble is sent for the last time, within a RAR time window corresponding to the second beam on which the random access preamble is sent for the last time.
