Abstract

A connection engine and coexistence manager are employed to manage radio resources in a user equipment. The connection engine defines desired performance metrics for sets of radio resources. The coexistence manager allocates potentially interfering radio resources to achieve desired performance metrics while accounting for resource capacity, potential collision rates, and other metrics.

Claims

1. A method used in a wireless communication system, the method comprising:

identifying a first set of data with a first performance criteria to be supported on a first set of radio resources;

identifying a second set of data with a second performance criteria to be supported; and

determining, based on an expected collision rate between the first set of radio resources and other radio resources, whether an allocation of radio resources to the first set of data and the second set of data exists to achieve the first performance criteria and second performance criteria.

2. The method of claim 1 further comprising implementing the determined allocation of radio resources.

3. The method of claim 1 in which the first performance criteria and second performance criteria are target traffic rates.

4. The method of claim 1 in which the determining further comprises determining when an allocation of the first set of radio resources to the first set of data and the second set of data exists to achieve the first performance criteria and second performance criteria.

5. The method of claim 1 in which the determining further comprises determining when an allocation of more than one set of radio resources to the first set of data and the second set of data exists to achieve the first performance criteria and second performance criteria.

6. The method of claim 5 in which the determining is based on an assessment of a capacity region of the first set of radio resources, a capacity region of a second set of radio resources, the first performance criteria, and the second performance criteria.

7. The method of claim 5 further comprising activating a second set of radio resources to achieve the first performance criteria and second performance criteria.

8. The method of claim 1 in which the expected collision rate is based on at least one of a link capacity, performance criteria, and channel conditions of the first set of radio resources.

9. The method of claim 1 in which the expected collision rate is based on the first performance criteria and second performance criteria.

10. The method of claim 1 further comprising altering the allocation of radio resources based on a change in at least one of the expected collision rate, the first performance criteria and the second performance criteria, the altering achieving the first performance criteria, including when altered, and second performance criteria, including when altered.

11. The method of claim 1 in which the allocation is based on performance criteria for the radio resources to be allocated.

12. The method of claim 1 in which the first set of radio resources comprises at least one of a radio access technology, a set of frequencies, and a set of subframes.

13. The method of claim 1 in which identifying performance criteria of the first set of data and the identifying performance criteria of the second set of data are performed by a connection engine and the determining is performed by a coexistence manager.

14. An apparatus operable in a wireless communication system, the apparatus comprising:

means for determining, based on an expected collision rate between the first set of radio resources and other radio resources, whether an allocation of radio resources to the first set of data and the second set of data exists to achieve the first performance criteria and second performance criteria.

15. A computer program product configured for wireless communication, the computer program product comprising:

a computer-readable medium having non-transitory program code recorded thereon, the program code comprising;
