Abstract

A different inter radio access technology (IRAT) measurement schedule is provided in the execution phase relative to the IRAT measurement schedule implemented in the preparation phase. To improve the handover performance, the user equipment transmits an IRAT measurement report for multiple neighbor cells and prioritizes the IRAT measurement scheduling for neighbor cells triggering the IRAT measurement report. The prioritizing occurs until an IRAT handover command is received.

Claims

1. A method of wireless communication, comprising:

transmitting an inter radio access technology (IRAT) measurement report for a plurality of neighbor cells; and

prioritizing IRAT measurement scheduling for the plurality of neighbor cells triggering the IRAT measurement report until an IRAT handover command is received.

2. The method of claim 1, in which the prioritizing comprises allocating more idle time slots and/or a longer gap length for IRAT measurement for the plurality of neighbor cells triggering the measurement report.

3. The method of claim 1, in which prioritizing further comprises increasing a measurement frequency for the plurality of neighbor cells triggering the measurement report.

4. The method of claim 1, further comprising allocating fewer idle time slots and/or a shorter gap length for IRAT measurement for neighbor cells not triggering the measurement report

5. The method of claim 1, further comprising decreasing a measurement frequency for neighbor cells not triggering the measurement report.

6. An apparatus for wireless communication, comprising:

means for transmitting an inter radio access technology (IRAT) measurement report for a plurality of neighbor cells; and

means for prioritizing IRAT measurement scheduling for the plurality of neighbor cells triggering the IRAT measurement report until an IRAT handover command is received.

7. The apparatus of claim 6, in which the prioritizing means further comprises means for allocating more idle time slots and/or a longer gap length for IRAT measurement for the plurality of neighbor cells triggering the measurement report.

8. The apparatus of claim 6, in which the prioritizing means further comprises means for increasing measurement frequency for the plurality of neighbor cells triggering the measurement report.

9. The apparatus of claim 6, in which the prioritizing means further comprises means for allocating fewer idle time slots and/or a shorter gap length for IRAT measurement for neighbor cells not triggering the measurement report

10. The apparatus of claim 6, fin which the prioritizing means further comprises means for decreasing a measurement frequency for neighbor cells not triggering the measurement report.

11. An apparatus for wireless communication, comprising:

a memory; and

at least one processor coupled to the memory and configured;

to transmit an inter radio access technology (IRAT) measurement report for a plurality of neighbor cells; and

to prioritize IRAT measurement scheduling for the plurality of neighbor cells triggering the IRAT measurement report until an IRAT handover command is received.

12. The apparatus of claim 11, in which the at least one processor is further configured to prioritize by allocating more idle time slots and/or a longer gap length for IRAT measurement for the plurality of neighbor cells triggering the measurement report.

13. The apparatus of claim 11, in which the at least one processor is further configured to prioritize by increasing a measurement frequency for the plurality of neighbor cells triggering the measurement report.

14. The apparatus of claim 11, in which the at least one processor is further configured to allocate fewer idle time slots and/or a shorter gap length for IRAT measurement for neighbor cells not triggering the measurement report.

15. The apparatus of claim 11, in which the at least one processor is further configured to decrease a measurement frequency for neighbor cells not triggering the measurement report.

16. A computer program product for wireless communications in a wireless network, comprising:

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

program code to transmit an inter radio access technology (IRAT) measurement report for a plurality of neighbor cells; and

program code to prioritize IRAT measurement scheduling for the plurality of neighbor cells triggering the IRAT measurement report until an IRAT handover command is received.

17. The computer program product of claim 16, in which the program code to prioritize further comprises program code to prioritize by allocating more idle time slots and/or a longer gap length for IRAT measurement for the plurality of neighbor cells triggering the measurement report.

18. The computer program product of claim 16, in which the program code to prioritize further comprises program code to prioritize by increasing a measurement frequency for the plurality of neighbor cells triggering the measurement report.

19. The computer program product of claim 16, in which the program code to prioritize further comprises program code to allocate fewer idle time slots and/or a shorter gap length for IRAT measurement for neighbor cells not triggering the measurement report

20. The computer program product of claim 16, in which the program code to prioritize further comprises program code to decrease a measurement frequency for neighbor cells not triggering the measurement report.
