Abstract
A method and apparatus for providing Multi-media Broadcast Multicast Services (MBMS) data to user equipment in a Multi-media Broadcast over a Single Frequency Network (MBSFN) environment over relay nodes are provided. The method includes periodically evaluating a synchronization delay associated with relay nodes in an MBSFN area by a DeNB, and assigning resources to the relay nodes for communicating MBMS data. The method also includes setting a time stamp in synchronization packets based on the synchronization delay. The time stamp information may indicate a start time for synchronized transmission of the MBMS data to user equipment in the MBSFN area over an air interface. The method may further include transmitting the synchronization packets including the MBMS data and time stamp information to the relay nodes using the allocated resources such that the MBMS data is synchronously transmitted to the user equipment by the relay nodes.
