Abstract

A random access method, device, and equipment are disclosed. The method includes: receiving, by a network node, a random access request, wherein the random access request comprises a preamble and a first data block; and sending, by the network node, a random access response.

First claim

What is claimed is:

1. A wireless communication method for performing a random-access procedure, comprising:
receiving, by a network node, a random access request from a terminal, wherein the random access request comprises a preamble and a first data block, and wherein the random access request comprises control information associated with the random-access procedure;
transmitting, by the network node in response to the random access request, a random access response to the terminal, wherein the random access response that fails to include the same control information in the random access request signals a transmission of a second data block; and
receiving, by the network node in response to the random access response, the second data block from the terminal,
wherein the random access response comprises:
uplink grant information for allocating an uplink resource for the transmission of the second data block and a preamble identification corresponding to the preamble in the random access request.

2. The method according to claim 1 , wherein the second data block comprises information that is the same as the first data block.

3. The method according to claim 1 , wherein the first data block and the second data block comprise a terminal identification.

4. The method according to claim 1 , wherein after the network node receives the second data block, the method further comprises:
notifying, by the network node, the terminal of a terminal identification.

5. A wireless communication method for performing a random-access procedure, comprising:
transmitting, by a terminal, a random access request to a network node, wherein the random access request comprises a preamble and a first data block, and wherein the random access request comprises control information associated with the random-access procedure;
receiving, by the terminal, a random access response from the network node in response to the random access request, wherein the random access response that fails to include the same control information in the random access request signals a transmission of a second data block; and
transmitting, by the terminal in response to the random access response, the second data block to the network node,
wherein the random access response comprises uplink grant information for allocating an uplink resource for the transmission of the second data block and a preamble identification corresponding to the preamble in the random access request.

6. The method according to claim 5 , wherein the second data block comprises information that is the same as the first data block.

7. The method according to claim 5 , wherein the first data block and the second data block comprise a terminal identification.

8. The method according to claim 5 , comprising, after transmitting the second data block:
receiving, by the terminal, a terminal identification from the network node.

9. A wireless communication device, comprising a processor configured to:
receive a random access request from a terminal, wherein the random access request comprises a preamble and a first data block, and wherein the random access request comprises control information associated with a random-access procedure;
transmit, in response to the random access request, a random access response to the terminal, wherein the random access response that fails to include the same control information in the random access request signals a transmission of a second data block; and
receive, in response to the random access response, the second data block from the terminal,
wherein the random access response comprises uplink grant information for allocating an uplink resource for the second data block and a preamble identification corresponding to the preamble in the random access request.

10. The device of claim 9 , wherein the second data block comprises information that is the same as the first data block.

11. The device of claim 9 , wherein the first data block and the second data block comprise a terminal identification.

12. The device of claim 9 , wherein the processor is configured to, after receiving the second data block, notify the terminal of a terminal identification.

13. A wireless communication device, comprising a processor configured to:
transmit a random access request to a network node, wherein the random access request comprises a preamble and a first data block, and wherein the random access request comprises control information associated with a random-access procedure;
receive, in response to the random access request, a random access response from the network node, wherein the random access response that fails to include the same control information in the random access request signals a transmission of a second data block; and
transmit, in response to the random access response, the second data block to the network node,
wherein the random access response comprises uplink grant information for allocating an uplink resource for the transmission of the second data block and a preamble identification corresponding to the preamble in the random access request.

14. The device of claim 13 , wherein the second data block comprises information that is the same as the first data block.

15. The device of claim 13 , wherein the first data block and the second data block comprises a terminal identification.

16. The device of claim 13 , wherein the processor is configured to, after transmitting the second data block, receive a terminal identification from the network node.
