Abstract
A random access method, a terminal device and a network device are provided. The method includes: selecting randomly, by a terminal device, a preamble for the terminal device to perform random access from multiple preambles; sending, by the terminal device, a first message to the network device, wherein the first message includes the preamble, random access information and an index for indicating a size of the random access information, and the random access information is control signaling related to Radio Resource Control (RRC) sent by the terminal device or data sent by the terminal device based on a random access event.
Claims20
A random access method, comprising:
- selecting randomly, by a terminal device, a preamble for the terminal device to perform random access from a plurality of preambles during a 2-step Random Access process of the terminal device;
- and
- sending, by the terminal device, a first message to a network device, wherein the first message comprises the preamble, random access information, and an index for indicating a size of the random access information, and the random access information is control signaling related to Radio Resource Control (RRC) sent by the terminal device or data sent by the terminal device based on a random access event.
A terminal device, comprising:
- a processor and a transceiver, wherein
- the processor is configured to select randomly a preamble for the terminal device to perform random access from a plurality of preambles during a 2-step Random Access process of the terminal device;
- and
- the transceiver is configured to send a first message to a network device, wherein the first message comprises the preamble, random access information, and an index indicating a size of the random access information, and the random access information is control signaling related to Radio Resource Control (RRC) sent by the terminal device or data sent by the terminal device based on a random access event.
A network device, comprising:
- a transceiver, wherein
- the transceiver is configured to receive a first message from a terminal device;
- wherein the first message comprises a preamble, random access information, and an index indicating a size of the random access information, and the random access information is control signaling related to Radio Resource Control (RRC) sent by the terminal device or data sent by the terminal device based on a random access event;
- wherein the preamble is selected randomly by the terminal device from a plurality of preambles to perform random access during a 2-step Random Access process of the terminal device.
