Abstract

A wireless communication device is provided with a first radio module and a second radio module inside. The first radio module performs wireless transceiving according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively. The second radio module determines an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively. Particularly, one or more allocations of the second slots are selectively determined according to the first traffic patterns. Also, the second radio module transmits the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations according to the indicator.

Claims

1. A wireless communication device, comprising:

a first radio module, performing wireless transceiving in compliance with a first communication protocol and according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively; and

a second radio module, performing wireless transceiving in compliance with a second communication protocol, determining an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively, and transmitting the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations to and from the second radio module according to the at least one of the second traffic patterns indicated by the indicator,

wherein one or more allocations of the second slots are selectively determined by the second radio module according to the first traffic patterns, prior to the determining of the indicator, wherein one or more allocations of the second slots are canceled by the second radio module when the receiving operations in the corresponding second slots are estimated to be interfered by the transmitting operations of the first radio module, and wherein one or more allocations of the second slots are canceled by the second radio module when data transmissions in the corresponding second slots are estimated to be interfering with the receiving operations of the first radio module.

2. The wireless communication device as claimed in claim 1, wherein the second radio module further performs transmitting or receiving operations to and from the peer communication device according to the at least one of the second traffic patterns indicated by the indicator.

3. The wireless communication device as claimed in claim 1, wherein one or more allocations of the second slots are canceled when acknowledgements of data transmissions in the corresponding second slots are estimated

to not have been received successfully due to interference from the first radio module.

4. The wireless communication device as claimed in claim 1, wherein the indicator is determined according to an operation status of the first radio module.

5. The wireless communication device as claimed in claim 4, wherein the determining of the indicator and the wireless transceiving are performed by the second radio module in response to a change of the operation status of the first radio module.

6. The wireless communication device as claimed in claim 4, wherein the first radio module generates a notification signal indicating a change of the operation status in a forthcoming period of time, and the determining of the indicator and the wireless transceiving are performed by the second radio module in response to the notification signal and the change of the operation status, respectively.

7. The wireless communication device as claimed in claim 1, wherein the second traffic patterns are predetermined in the second radio module and the wireless communication device.

8. The wireless communication device as claimed in claim 1, wherein the second traffic patterns are transmitted by the second radio module to the wireless communication device, prior to the determining of the indicator.

9. An activity coordination method for a wireless communication device comprising a plurality of co-located radio modules, comprising:

providing a first radio module for performing wireless transceiving in compliance with a first communication protocol and according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively;

providing a second radio module for performing wireless transceiving in compliance with a second communication protocol;

determining, by the second radio module, an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively,

wherein one or more allocations of the second slots are selectively determined by the second radio module according to the first traffic patterns; and

transmitting, by the second radio module, the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations to and from the second radio module according to the at least one of the second traffic patterns indicated by the indicator,

wherein one or more allocations of the second slots are canceled by the second radio module when the receiving operations in the corresponding second slots are estimated to be interfered by the transmitting operations of the first radio module, and wherein one or more allocations of the second slots are canceled by the second radio module when data transmissions in the corresponding second slots are estimated to be interfering with the receiving operations of the first radio module.

10. The activity coordination method as claimed in claim 9, further comprising configuring the second radio module to perform transmitting or receiving operations to and from the peer communication device according to the at least one of the second traffic patterns indicated by the indicator.

11. The activity coordination method as claimed in claim 9, wherein one or more allocations of the second slots are canceled when acknowledgements of data transmissions in the corresponding second slots are estimated to not have been received successfully due to interference from the first radio module.

12. The activity coordination method as claimed in claim 9, wherein the indicator is determined according to an operation status of the first radio module.

13. The activity coordination method as claimed in claim 12, wherein the steps of determining the indicator and configuring the second radio module are performed in response to a change of the operation status of the first radio module.

14. The activity coordination method as claimed in claim 12, further comprising generating a notification signal indicating a change of the operation status of the first radio module in a forthcoming period of time, wherein the steps of determining the indicator and configuring the second radio module are performed in response to the notification signal and the change of the operation status, respectively.

15. The activity coordination method as claimed in claim 9, wherein the second traffic patterns are predetermined in the second radio module and the wireless communication device.

16. The activity coordination method as claimed in claim 9, further comprising transmitting, by the second radio module, the second traffic patterns to the wireless communication device, prior to determining the indicator.
