Abstract

A communication method includes communicating between a terminal device and a first network device via a first uplink capability. The terminal device includes a first communication card and a second communication card. The method also includes sending a first message to the first network device from the terminal device. The first message indicates a second uplink capability to communicate between the terminal device and the first network device. The method additionally includes communicating between the terminal device and a second network device via a third uplink capability.

First claim

What is claimed is:

1. A communication method, comprising:
communicating between a terminal device and a first network device via a first uplink capability, wherein the terminal device includes a first communication card and a second communication card;
sending a first message to the first network device from the terminal device, wherein the first message indicates a second uplink capability to communicate between the terminal device and the first network device; and
communicating between the terminal device and a second network device via a third uplink capability,

wherein
the second uplink capability is less than the first uplink capability,
the third uplink capability is different from the first uplink capability, and
the first uplink capability indicates a first quantity of uplink radio frequency links, the second uplink capability indicates a second quantity of uplink radio frequency links, and the third uplink capability indicates a third quantity of uplink radio frequency links.

2. The method according to claim 1 , wherein a first throughput of the first uplink capability is greater than a second throughput of the second uplink capability.

3. The method according to claim 1 , wherein the method further comprises:
sending a second message to the second network device from the terminal device, wherein the second message indicates the third uplink capability.

4. The method according to claim 1 , wherein the method further comprises:
sending a first time parameter to the first network device from the terminal device, wherein the first time parameter is a time parameter of the second uplink capability.

5. The method according to claim 1 , wherein the method further comprises:
sending a second time parameter to the second network device from the terminal device, wherein the second time parameter is a time parameter of the third uplink capability.

6. The method according to claim 1 , wherein the method further comprises:
sending a first subframe parameter to the first network device from the terminal device, wherein the first subframe parameter is a parameter of a subframe of the second uplink capability.

7. The method according to claim 1 , wherein the method further comprises:
sending a second subframe parameter to the second network device from the terminal device, wherein the second subframe parameter is a parameter of a subframe of the third uplink capability.

8. The method according to claim 1 , wherein the first uplink capability is N uplink radio frequency link capabilities, the second uplink capability is M uplink radio frequency link capabilities, and the third uplink capability is N-M-P uplink radio frequency link capabilities, wherein N is a positive integer greater than or equal to 2, M is a positive integer greater than or equal to 1, M is less than N, and P is an integer greater than or equal to 0 and less than N−M.

9. The method according to claim 1 , wherein the first communication card corresponds to the first uplink capability and the second uplink capability, and the second communication card corresponds to the third uplink capability.

10. The method according to claim 1 , wherein the first network device and the second network device are on a network accessible to the first network device and the second network device.

11. A dual communication card-based communication method, comprising:
communicating between a network device and a terminal device via a first uplink capability, wherein a first communication card and a second communication card are included in the terminal device; and
receiving a first message at the network device from the terminal device, wherein the first message indicates a second uplink capability to communicate between the terminal device and the network device, wherein
the second uplink capability is less than the first uplink capability,
the first uplink capability indicates a first quantity of uplink radio frequency links, and
the second uplink capability indicates a second quantity of uplink radio frequency links.

12. The method according to claim 11 , wherein a first throughput of the first uplink capability is greater than a second throughput of the second uplink capability.

13. The method according to claim 11 , wherein the method further comprises:
receiving a first time parameter at the network device from the terminal device, wherein the first time parameter is a time parameter of the second uplink capability.

14. The method according to claim 11 , wherein the method further comprises:
receiving a first subframe parameter from the terminal device, wherein the first subframe parameter is a parameter of a subframe of the second uplink capability.

15. The method according to claim 11 , wherein the method further comprises:
communicating between the network device and the terminal device via a third uplink capability.

16. The method according to claim 11 , wherein the method further comprises:
receiving a second message at the network device from the terminal device, wherein the second message indicates a third uplink capability to communicate between the terminal device and the network device.

17. The method according to claim 15 , wherein the method further comprises:
receiving a second time parameter at the network device from the terminal device, wherein the second time parameter is a time parameter of the third uplink capability.

18. The method according to claim 15 , wherein the method further comprises:
receiving a second subframe parameter at the network device from the terminal device, wherein the second subframe parameter is a parameter associated with a subframe of the third uplink capability.

19. The method according to claim 15 , wherein the first uplink capability is N uplink radio frequency link capabilities, the second uplink capability is M uplink radio frequency link capabilities, and the third uplink capability is N-M-P uplink radio frequency link capabilities, wherein N is a positive integer greater than or equal to 2, M is a positive integer greater than or equal to 1, M is less than N, and P is an integer greater than or equal to 0 and less than N-M.

20. A terminal device, comprising:
a processor and a memory having instructions stored thereon that, when executed by the processor, cause the terminal device to:
communicate with a first network device via a first uplink capability;
send a first message to the first network device, wherein the first message indicates a second uplink capability for communication between the terminal device and the first network device, wherein the second uplink capability is less than the first uplink capability; and
