Abstract

A method of configuring a random access resource, a terminal, and a network node are provided. The method includes: receiving configuration information of a physical random access channel PRACH resource transmitted by a network node; wherein the configuration information is configured to indicate a PRACH transmission resource reserved by the network node for the terminal and used to transmit a beam failure recovery request.

Claims

receiving configuration information of a Physical Random Access Channel (PRACH) resource transmitted by a network node;

wherein the configuration information is configured to indicate a PRACH transmission resource reserved by the network node for the terminal and used to transmit a beam failure recovery request.

2. The method of configuring a random access resource according to claim 1, wherein, receiving the configuration information of the PRACH resource transmitted by the network node, comprises:

receiving the configuration information of the PRACH resource transmitted at preset time by the network node;

wherein, the preset time comprises at least one of;

a first preset time duration prior to a start of service transmission, a second preset time duration after the start of service transmission, and time when a beam failure is detected for a first time after an access of the terminal is completed.

3. The method of configuring a random access resource according to claim 1, wherein, receiving the configuration information of the PRACH resource transmitted by the network node, comprises:

transmitting request information for requesting the PRACH resource to the network node; and

receiving the configuration information of the PRACH resource transmitted by the network node according to the request information.

4. The method of configuring a random access resource according to claim 1, wherein, receiving the configuration information of the PRACH resource transmitted by the network node, comprises:

receiving, through preset downlink information, the configuration information of the PRACH resource transmitted by the network node;

wherein, the downlink information comprises at least one of;

a broadcast message, a system message, a Radio Resource Control (RRC) configuration message, a RRC reconfiguration message, and control information corresponding to a physical downlink control channel.

5. The method of configuring a random access resource according to claim 1, wherein, the configuration information comprises:

information of preamble sequence codes for carrying the beam failure recovery request, and/or grouping information of the preamble sequence codes.

6. The method of configuring a random access resource according to claim 5, wherein, the preamble sequence code comprise a part of preamble sequence codes within a first predetermined group and/or a part of preamble sequence codes within a second predetermined group;

and/or

the grouping information is used to indicate whether a preamble sequence code within a current group is used for transmitting the beam failure recovery request or not.

9. The method of configuring a random access resource according to claim 1, wherein, after receiving the configuration information of the PRACH resource transmitted by the network node, the method further comprises:

receiving an activation instruction or a deactivation instruction transmitted by the network node;

wherein the activation instruction is configured to activate the PRACH resource, and the deactivation instruction is configured to deactivate the PRACH resource.

12. The method of configuring a random access resource according to claim 9, wherein, after receiving the activation instruction or the deactivation instruction transmitted by the network node, the method further comprises:

feeding back acknowledgement (ACK) information/non-acknowledgement (NACK) information to the network node according to the activation instruction or the deactivation instruction.

13. The method of configuring a random access resource according to claim 1, wherein, after receiving the configuration information of the PRACH resource transmitted by the network node, the method further comprises:

receiving a release instruction transmitted by the network node, wherein the release instruction is used to release the PRACH resource.

17. The method of configuring a random access resource according to claim 1, wherein, after receiving the configuration information of the PRACH resource transmitted by the network node, the method further comprises:

transmitting, in a case that a beam failure is detected, the beam failure recovery request to the network node through the PRACH resource.

35. A terminal, comprising:

a processor and a storage, wherein a computer program executable by the processor is stored in the storage, and when the computer program is executed by the processor, the processor implements steps of the method of configuring a random access resource according claim 1.
