<p>The present invention provides a method, a base station and a computer program product for data synchronisation of collaborative MIMO in an OFDMA system, the OFDMA system comprising a network element coupled to at least a first and a second base station, the first and second base station coupled to at least a wireless terminal, the method comprising the steps of: receiving a collaborative MIMO connection request from the wireless terminal by the first or second base station; sending a duplication request signal to the network element from the first base station, the duplication signal indicating a duplication of a collaborative IP flow for the wireless terminal; receiving a first IP packet of the collaborative IP flow from the core network by the network element. The method further comprises the steps of copying the first IP packet and sending it to at least the first and second base station; receiving the first IP packet by the first base station and scheduling a first portion of a first downlink frame; sending a frame layout message from the first base station to the second base station, the frame layout message containing a description about the first portion of the first downlink frame; scheduling a second portion of a second downlink frame by the second base station with the description of the first portion of the first downlink frame, wherein the first and second portion of the first and second downlink frames are identical.</p> |
