Abstract
A random access method method includes: an access network device receiving a message A that is sent by a terminal, the message A comprising a random access preamble sequence and physical uplink shared channel (PUSCH) data; the access network device sending a first response message or a second response message, the first response message being used to instruct the terminal to send message 3 in a 4-step random access process, the second response message being used to instruct the terminal to send a re-transmission message of the message A, and the re-transmission message at least comprising the PUSCH data.
Claims19
A random access method, comprising:
- receiving, by an access network device, a message A sent by a terminal, wherein the message A comprises a random access preamble sequence and physical uplink shared channel (PUSCH) data;
- sending, by the access network device, a first response message or a second response message to the terminal when determining that the PUSCH data in the message A fails to be parsed, wherein the first response message is used to indicate the terminal to send a message 3 in a 4-step random access procedure, the second response message is used to indicate the terminal to send a retransmission message of the message A, and the retransmission message comprises at least the PUSCH data;
- and
- determining, by the access network device, to send the first response message or send the second response message based on random access selection reference information, wherein the random access selection reference information comprises at least one of a user type, an intra-cell interference level, a delay between the terminal and the access network device and a cell load amount.
A random access method, comprising:
- sending, by a terminal, a message A to an access network device, wherein the message A comprises a random access preamble sequence and physical uplink shared channel (PUSCH) data;
- and
- receiving, by the terminal, a first response message or a second response message sent by the access network device based on random access selection reference information, wherein the first response message is used to indicate the terminal to send a message 3 in a 4-step random access procedure, the second response message is used to indicate the terminal to send a retransmission message, the retransmission message comprises at least the PUSCH data, and wherein the random access selection reference information comprises at least one of a user type, an intra-cell interference level, a latency between an expected reception time and an actual reception time of a measurement signal by the access network device.
A random access device, comprising:
- a processor;
- and
- a memory for storing executable instructions of the processor;
- wherein the processor is configured to load and execute the executable instructions to implement:
- receiving a message A sent by a terminal, wherein the message A comprises a random access preamble sequence and physical uplink shared channel (PUSCH) data;
- sending a first response message or a second response message to the terminal when determining that the PUSCH data in the message A fails to be parsed, wherein the first response message is used to indicate the terminal to send a message 3 in a 4-step random access procedure, the second response message is used to indicate the terminal to send a retransmission message of the message A, and the retransmission message comprises at least the PUSCH data;
- and
- determining to send the first response message or send the second response message based on random access selection reference information, wherein the random access selection reference information comprises at least one of a user type, an intra-cell interference level, a delay between the terminal and an access network device and a cell load amount.
