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 method for wireless communication, comprising:
configuring, by a network node, resources for multiple terminal devices to transmit a random-access preamble; and
receiving, by the network node, a random-access request from a terminal device of the multiple terminal devices, wherein the random-access request comprises the random-access preamble that is transmitted using part of the configured resources, wherein the part of the configured resources corresponds to an identifier of the terminal device, wherein the random-access request further comprises at least control information or data information,
the method comprising:
transmitting, by the network node, a response to the terminal device indicating a failure of demodulating the at least control information or data information; and
receiving, by the network node, a retransmission of the at least control information or data information based on the part of the configured resources for the random-access preamble or an uplink grant.

2. The method of claim 1 , wherein the configured resources are divided into multiple parts, each allocated to one of the multiple terminal devices.

3. The method of claim 2 , wherein the identifier of the terminal device is denoted as UE_ID and wherein M terminal devices are configured with the resources for the random-access preamble, and wherein the resources are divided based on UE_ID mod M.

4. The method of claim 1 , wherein
the response further comprising the uplink grant indicating resources for the retransmission of the at least control information or data information.

5. A method for wireless communication, comprising:
receiving, by a terminal device, information from a network node about configured resources for multiple terminal devices to transmit a random-access preamble;
determining, by the terminal device, part of the configured resources for the random-access preamble based on an identifier of the terminal device; and
transmitting, by the terminal device, a random-access request to the network node using the part of the configured resources, wherein the random-access request further comprises at least control information or data information,
the method comprising:
receiving, by the terminal device, a response from the network node indicating a failure of demodulating the at least control information or data information; and
performing, by the terminal device, a retransmission of the at least control information or data information based on the part of the configured resources for the random-access preamble or an uplink grant.

6. The method of claim 5 , wherein the configured resources are divided into multiple parts, each allocated to one of the multiple terminal devices.

7. The method of claim 6 , wherein the identifier of the terminal device is denoted as UE_ID and wherein M terminal devices are configured with the configured resources for the random-access preamble, and wherein the configured resources are divided based on UE_ID mod M.

8. The method of claim 5 , wherein
the response further comprising the uplink grant indicating resources for the retransmission of the at least control information or data information.

9. A device for wireless communication, comprising:
one or more processors; and
at least one non-transitory memory having one or more instructions stored thereon, wherein, when executed by the one or more processors, configure the one or more processors to:
configure resources for multiple terminal devices to transmit a random-access preamble; and
receive a random-access request from a terminal device of the multiple terminal devices, wherein the random-access request comprises the random-access preamble that is transmitted using part of the configured resources, wherein the part of the configured resources is selected based on an identifier of the terminal device, wherein the random-access request further comprises at least control information or data information,
wherein the one or more processors are further configured to:
transmit a response to the terminal device indicating a failure of demodulating the at least control information or data information; and
receive a retransmission of the at least control information or data information based on the part of the configured resources for the random-access preamble or an uplink grant.

10. The device of claim 9 , wherein the configured resources are divided into multiple parts, each allocated to one of the multiple terminal devices.

11. The device of claim 10 , wherein the identifier of the terminal device is denoted as UE_ID and wherein M terminal devices are configured with the resources for the random-access preamble, and wherein the resources are divided based on UE_ID mod M.

12. The device of claim 9 , wherein
the response further comprises the uplink grant indicating resources for the retransmission of the at least control information or data information.

13. A device of wireless communication, comprising one or more processors that are configured to:
receive, from a network node, information about configured resources for multiple terminal devices to transmit a random-access preamble;
determine part of the configured resources for the random-access preamble based on an identifier of the device; and
transmit a random-access request to the network node using the part of the configured resources, wherein the random-access request further comprises at least control information or data information, and
wherein the one or more processors are configured to:
receive a response from the network node indicating a failure of demodulating the at least control information or data information; and
perform a retransmission of the at least control information or data information based on the part of the configured resources for the random-access preamble or an uplink grant.

14. The device of claim 13 , wherein the configured resources are divided into multiple parts, each allocated to one of the multiple terminal devices.

15. The device of claim 14 , wherein the identifier of the device is denoted as UE_ID and wherein M terminal devices are configured with the configured resources for the random-access preamble, and wherein the configured resources are divided based on UE_ID mod M.

16. The device of claim 13 , wherein
the response further comprises the uplink grant indicating resources for the retransmission of the at least control information or data information.
