Abstract:
1. A method for wireless communication, comprising: receiving, at a user equipment (UE), a handover command from a base station associated with a first radio access technology (RAT); determining, at the UE, at least a synchronization signal, a downlink pilot time slot, or a midamble of a second RAT based on a frame timing of the first RAT; calculating, at the UE, a system frame number (SFN) of a the second RAT based at least in part on a SFN of the first RAT stored in the UE, a frame boundary and the SFN of the first RAT being synchronous with a frame boundary and the SFN of the second RAT; and transmitting, from the UE, a handover complete message to a base station associated with the second RAT based at least in part on the calculated SFN of the second RAT and the determined synchronization signal, downlink pilot time slot, or midamble.
