Abstract
Providing for retransmission of SFN data, including SFN operated MBMS data, in a manner that preserves synchronization of scheduled SFN transmissions is disclosed herein. As an example, SFN data can be transmitted in a first allocation period, and an un-received or indecipherable SFN data packet associated with the SFN data can be scheduled in a second allocation period. More particularly, the un-received or indecipherable SFN data packet can be allocated to a block of the second allocation period that is scheduled for non-SFN transmission, for instance. Accordingly, SFN retransmission can take place on a cell by cell basis without substantially affecting SFN transmissions synchronized among the cells.
