MULTI-CELL COORDINATION FOR MULTIMEDIA BROADCAST MULTICAST SERVICES IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention is related to a method and system for multi-cell coordination for multimedia broadcast multicast services (MBMS) in a wireless communication system. An MBMS multi-cell coordination unit is provided to coordinate a plurality of evolved Node-Bs (eNodeBs) for transmission of MBMS data synchronously in multiple cells of the same single frequency network (SFN). The MBMS multi-cell coordination unit may be located in an access gateway or in an eNodeB. An MBMS multi-cell scheduling scheme may be preconfigured for the eNodeBs for synchronization. Alternatively, the eNodeBs may be synchronized dynamically.

1. An access gateway for controlling a plurality of evolved Node-Bs (eNodeBs) in a single frequency network (SFN), the access gateway comprising:
a control plane interface; a user plane interface; and a multimedia broadcast multicast services (MBMS) multi-cell coordination unit including:
a MBMS coordination control part coupled to the control plane interface and configured to coordinate control signaling to the eNodeBs of the SFN via the control plane interface, anda MBMS coordination data part coupled to the user plane interface and configured to coordinate data signaling to the eNodeBs of the SFN via the user plane interface, wherein the MBMS multi-cell coordination unit is configured to:
receive information for determining a start time of the eNodeBs in the SFN for multicasting data from the eNodeBs, andsend a scheduling scheme to provide a common configuration and a timestamp, corresponding to the determined start time, for start time synchronization of the multicasting of the data from the eNodeBs of the SFN.
