Abstract

A wireless communication system is presented for multiple wireless technology coexistence in a mobile device. A method according to this application might include obtaining one or more transmit allocation parameters for a wireless transmission via a first radio technology at a first wireless processor and the preparing to receive wireless data via a second radio technology at a second wireless processor. Next, the exemplary method might request that the wireless transmission be deferred, followed by deciding whether to grant the deferral request based at least on the one or more transmit allocation parameters.

Claims

1. An apparatus, comprising:

first circuitry configured for wireless communication using a first radio access technology (RAT); and

second circuitry configured for wireless communication using a second RAT that is different than the first RAT;

wherein the apparatus is configured to;

when the first circuitry will be using the first RAT during a first time interval in which a transmission is scheduled using the second RAT, determine a value of a configurable parameter for at least one of;

the use of the first RAT or the scheduled transmission; and

defer the scheduled transmission based at least in part on the determined value of the configurable parameter.

2. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of the configurable parameter for the use of the first RAT; and

wherein the configurable parameter for use of the first RAT comprises a frequency allocation.

3. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of the configurable parameter for the use of the first RAT; and

wherein the configurable parameter for use of the first RAT comprises a duration of the use of the first RAT.

4. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of multiple configurable parameters for the use of the first RAT, including a frequency allocation and a duration of use; and

defer the scheduled transmission based at least in part on the determined value of one or more of the multiple configurable parameters.

5. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of the configurable parameter for the scheduled transmission; and

wherein the configurable parameter comprises a number of resource blocks used by the scheduled transmission.

6. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of the configurable parameter for the scheduled transmission; and

wherein the configurable parameter comprises a transmit power of the scheduled transmission.

7. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of the configurable parameter for the scheduled transmission; and

wherein the configurable parameter comprises an allocated frequency of the scheduled transmission.

8. The apparatus of claim 1, wherein the apparatus is configured to:

determine the value of multiple configurable parameters for the scheduled transmission, including a number of resource blocks associated with the scheduled transmission, a transmit power of the scheduled transmission, and a frequency of a particular resource block associated with the scheduled transmission; and

wherein the apparatus is configured to defer the scheduled transmission based at least in part on one or more of the determined values of the multiple configurable parameters.

9. The apparatus of claim 1, wherein the apparatus is configured to:

determine values of at least one configurable parameter for the use of the first RAT and at least one configurable parameter for the scheduled transmission; and

wherein the apparatus is configured to defer the scheduled transmission based at least in part on the determined values of the at least one configurable parameter for the use of the first RAT and the at least one configurable parameter for the scheduled transmission.

10. The apparatus of claim 1, wherein the first RAT comprises a wireless local area network (WLAN) RAT and the second RAT comprises a cellular RAT.

11. The apparatus of claim 1, wherein the apparatus is configured to perform multiple-input multiple-output communications via the second RAT.

12. A non-transitory computer-readable medium having instructions stored thereon that are executable by a mobile device to perform operations comprising:

in response to determining that the mobile device will be using a first RAT during a first time interval in which the mobile device has a transmission scheduled using a second, different RAT, determining a value of a configurable parameter for at least one of;

the use of the first RAT or the scheduled transmission; and

deferring the scheduled transmission based at least in part on the determined value of the configurable parameter.

13. The non-transitory computer-readable medium of claim 12, wherein the determining is of the value of the configurable parameter for the use of the first RAT and wherein the configurable parameter comprises a frequency allocation.

14. The non-transitory computer-readable medium of claim 12, wherein the determining is of the value of the configurable parameter for the use of the first RAT and wherein the configurable parameter comprises a time duration.

15. The non-transitory computer-readable medium of claim 12, wherein the determining is of the configurable parameter for the scheduled transmission and the parameter comprises one or more of:

a number of resource blocks, an allocated frequency, or a transmit power.

16. The non-transitory computer-readable medium of claim 12, wherein the operations further comprise:

dynamically determining a threshold value for comparison with the value of the configurable parameter, wherein the threshold value can be used to determine whether to defer the scheduled transmission.

17. A method, comprising:

determining, by a computing device, in response to determining that the computing device will be using a first RAT during a first time interval in which the computing device has a transmission scheduled using a second, different RAT, a value of a configurable parameter for at least one of;

the use of the first RAT or the scheduled transmission; and

deferring, by the computing device, the scheduled transmission based at least in part on the determined value of the configurable parameter.

18. The method of claim 17, wherein the determining is of the value of the configurable parameter for the use of the first RAT and wherein the configurable parameter comprises a time duration.

19. The method of claim 17, wherein the determining is of the value of the configurable parameter for the use of the first RAT and wherein the configurable parameter comprises an allocated frequency.

20. The method of claim 17, wherein the determining is of the value of the configurable parameter for the scheduled transmission.
