A technique for controlling a wireless broadcast transmission of media data via multiple transmitter sites into a broadcast area with different inter-site distances is proposed. The broadcast area comprises a region of large inter-site distance (ISD) and a region of small inter-site distance. The technique provides for a high spectral efficiency in regions of small ISD and at the same time for an acceptable reception quality in regions of large ISD. A first transmission is initiated into the broadcast area, wherein the first transmission is adapted for reception in a first of the regions. A second transmission is initiated into a second of the regions, the second transmission being adapted for reception in the second region.

Hierarchical broadcast transmission via multiple transmitters

Inter-cell handover (or cell reselection) in order to provide load balancing in wireless networks, in particular in hierarchical (overlay) networks, wherein the mobile stations in the cells are associated to different multicast groups. A technique for assigning one or more members of a multicast group to cells of radio network is described. This technique includes determining among multicast group members in a first cell one or more first group members having the highest resource demand in this cell. Next, for each cell of a cell cluster and in relation to a second group member having the highest resource demand in the considered cell, the relative resource consumption increase if the one or more first group members were assigned to said considered cell is determined. This determination is also carried out for the first cell but disregarding the one or more first group members having the highest resource demand. These one or more first members are then assigned to the cell that is associated with a minimum compensated relative resource consumption increase or a minimum compensated relative resource increase. In one embodiment, the cells are hierarchically structured and the assignment of member of the multicast group cells is allowed to be carried out on different hierarchy layers.
