Abstract

A method for occupying resources in an unlicensed frequency band includes: when a cellular component of a terminal executes a first LBT process on a first frequency domain resource included in an unlicensed frequency band, a WiFi component of the terminal executes a second LBT process on a second frequency domain resource included in the unlicensed frequency band, wherein the first frequency domain resource and the second frequency domain resource are the same or different.

Claims (40)

1. A method for occupying resources in an unlicensed frequency band, comprising:

executing by a wireless fidelity (WiFi) component of a terminal, a second listen before talk (LBT) process on second frequency domain resources included in the unlicensed frequency band when a first LBT process on first frequency domain resources included in the unlicensed frequency band is jointly executed by a cellular component of the terminal;

wherein the first frequency domain resources and the second frequency domain resources are the same or different;

wherein the method further comprises: sending by the WiFi component, resource information to the cellular component when physical resources are competed by the WiFi component through the second LBT process, wherein the resource information is configured to indicate time-frequency positions of the physical resources competed by the WiFi component, and the cellular component is configured to occupy the physical resources based on the resource information for information transmission.

2. The method of claim 1 , further comprising:

when the WiFi component is in an idle state, executing by the WiFi component the second LBT process on the second frequency domain resources included in the unlicensed frequency band.

3. The method of claim 1 , further comprising:

receiving by the WiFi component, a stop notification sent by the cellular component, wherein the stop notification is sent after physical resources are competed by the cellular component through the first LBT process; and

stopping by the WiFi component, executing the second LBT process based on the stop notification.

4. The method of claim 1 , wherein sending by the WiFi component, the resource information to the cellular component comprises:

sending by the WiFi component, the resource information directly to the cellular component; and/or

sending by the WiFi component, the resource information to a processing component of the terminal, wherein the processing component is configured to forward the resource information to the cellular component.

5. A terminal, comprising:

a wireless fidelity (WiFi) component;

a cellular component;

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to:

control the WiFi component to execute a second listen before talk (LBT) process on second frequency domain resources included in the unlicensed frequency band when a first LBT process on first frequency domain resources included in the unlicensed frequency band is jointly executed by the cellular component;

wherein the first frequency domain resources and the second frequency domain resources are the same or different;

wherein the processor is further configured to control the WiFi component to send resource information to the cellular component when physical resources are competed by the WiFi component through the second LBT process, wherein the resource information is configured to indicate time-frequency positions of the physical resources competed by the WiFi component, and the cellular component is configured to occupy the physical resources based on the resource information for information transmission.

6. The terminal of claim 5 , wherein the processor is configured to control the WiFi component to execute the second LBT process on the second frequency domain resources included in the unlicensed frequency band when the WiFi component is in an idle state.

7. The terminal of claim 5 , wherein the WiFi component is configured to:

send the resource information directly to the cellular component; and/or

send the resource information to a processing component of the terminal, wherein the processing component is configured to forward the resource information to the cellular component.

8. The terminal of claim 5 , wherein the processor is further configured to:

control the cellular component to send a stop notification to the WiFi component after physical resources are competed by the cellular component through the first LBT process; and

control the WiFi component to stop executing the second LBT process based on the stop notification.

9. A non-transitory computer-readable storage medium having a computer program stored thereon, wherein when executed by a processor, the computer program is configured to implement a method for occupying resources in an unlicensed frequency band, the method comprising:

executing by a wireless fidelity (WiFi) component of a terminal, a second listen before talk (LBT) process on second frequency domain resources included in the unlicensed frequency band when a first LBT process on first frequency domain resources included in the unlicensed frequency band is jointly executed by a cellular component of the terminal;

wherein the first frequency domain resources and the second frequency domain resources are the same or different;

wherein the method further comprises: sending by the WiFi component, resource information to the cellular component when physical resources are competed by the WiFi component through the second LBT process, wherein the resource information is configured to indicate time-frequency positions of the physical resources competed by the WiFi component, and the cellular component is configured to occupy the physical resources based on the resource information for information transmission.

10. The storage medium of claim 9 , wherein the method further comprises:

when the WiFi component is in an idle state, executing by the WiFi component the second LBT process on the second frequency domain resources included in the unlicensed frequency band.

11. The storage medium of claim 9 , wherein sending by the WiFi component, the resource information to the cellular component comprises:

sending by the WiFi component, the resource information directly to the cellular component; and/or

sending by the WiFi component, the resource information to a processing component of the terminal, wherein the processing component is configured to forward the resource information to the cellular component.

12. The storage medium of claim 9 , further comprising:

receiving by the WiFi component, a stop notification sent by the cellular component, wherein the stop notification is sent after physical resources are competed by the cellular component through the first LBT process; and

stopping by the WiFi component, executing the second LBT process based on the stop notification.
