Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of wireless communication, comprising: Recording, by a user equipment (UE), an absolute system frame number (SFN) of a target radio access technology (RAT) and/or a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT; and determining, by the UE, a transmission time interval (TTI) boundary, after redirection, based at least in part on the recorded absolute system frame number (SFN) and/or the recorded relative system frame number (SFN) difference.
2. The method of claim 1 , further comprising skipping blind decoding of a broadcast control channel (BCCH) in the target RAT to read a SFN to determine the TTI boundary.
3. The method of claim 1 , in which the serving RAT is Long Term Evolution (LTE).
4. The method of claim 1 , in which the target RAT is time division-synchronous code division multiple access (TD-SCDMA).
5. The method of claim 1 , further comprising storing the recorded difference.
6. The method of claim 1 , in which recording the SFN difference occurs while camped in the target RAT.
7. The method of claim 1 , in which recording the SFN difference occurs during an inter-radio access technology (IRAT) measurement.
8. An apparatus for wireless communication, comprising: means for recording an absolute system frame number (SFN) of a target radio access technology (RAT) and/or a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT; and means for determining a transmission time interval (TTI) boundary, after redirection, based at least in part on the recorded absolute system frame number (SFN) and/or the recorded relative system frame number (SFN) difference.
9. The apparatus of claim 8 , further comprising means for skipping blind decoding of a broadcast control channel (BCCH) in the target RAT to read a SFN to determine the TTI boundary.
10. The apparatus of claim 8 , in which the serving RAT is Long Term Evolution (LTE).
11. The apparatus of claim 8 , in which the target RAT is time division-synchronous code division multiple access (TD-SCDMA).
12. The apparatus of claim 8 , further comprising means for storing the recorded difference.
13. The apparatus of claim 8 , in which the means for recording the SFN difference occurs while camped in the target RAT.
14. The apparatus of claim 8 , in which the means for recording the SFN difference occurs during an inter-radio access technology (IRAT) measurement.
15. A non-transitory computer-readable medium having program code recorded thereon, the program code comprising: program code to record an absolute system frame number (SFN) of a target radio access technology (RAT) and/or to record a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT; and program code to determine a transmission time interval (TTI) boundary, after redirection, based at least in part on the recorded absolute system frame number (SFN) and/or the recorded relative system frame number (SFN) difference.
16. The non-transitory computer-readable medium of claim 15 , further comprising program code to skip blind decoding of a broadcast control channel (BCCH) in the target RAT to read a SFN to determine the TTI boundary.
17. The non-transitory computer-readable medium of claim 15 , in which the serving RAT is Long Term Evolution (LTE).
18. The non-transitory computer-readable medium of claim 15 , in which the target RAT is time division-synchronous code division multiple access (TD-SCDMA).
19. The non-transitory computer-readable medium of claim 15 , further comprising program code to store the recorded difference.
20. The non-transitory computer-readable medium of claim 15 , in which the program code to record is further configured to record the SFN difference while a user equipment (UE) is camped in the target RAT.
21. The non-transitory computer-readable medium of claim 15 , in which the program code to record is further configured to record the SFN difference during an inter-radio access technology (IRAT) measurement.
22. An apparatus for wireless communication, comprising: a memory; and at least one processor coupled to the memory, the at least one processor being configured: to record an absolute system frame number (SFN) of a target radio access technology (RAT) and/or to record a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT; and to determine a transmission time interval (TTI) boundary, after redirection, based at least in part on the recorded absolute system frame number (SFN) and/or the recorded relative system frame number (SFN) difference.
23. The apparatus of claim 22 , in which the at least one processor is further configured to skip blind decoding of a broadcast control channel (BCCH) in the target RAT to read a SFN to determine the TTI boundary.
24. The apparatus of claim 22 , in which the serving RAT is Long Term Evolution (LTE).
25. The apparatus of claim 22 , in which the target RAT is time division-synchronous code division multiple access (TD-SCDMA).
26. The apparatus of claim 22 , in which the at least one processor is further configured to store the recorded difference.
27. The apparatus of claim 22 , in which the at least one processor is configured to record the SFN difference occurs while a user equipment (UE) is camped in the target RAT.
28. The apparatus of claim 22 , in which the at least one processor is configured to record the SFN difference during an inter-radio access technology (IRAT) measurement.
