Abstract
A method for controlling a heterogeneous wireless network (100) is proposed. The heterogeneous wireless network comprises at least one first base station (115) which manages communication of a plurality of first user equipments (125M) positioned in at least one first cell (105) and at least one second base station (120) which manages communication of a plurality of second user equipments (125p) positioned in at least one second cell (110). Moreover, in the heterogeneous network (100), for each first user equipment (125M) the at least one first base station (115) provides a respective first allocation information set over a respective first allocation time interval. Similarly, the at least one second base station (120) provides for each second user equipment (125p) a respective second allocation information set over a respective second allocation time interval. Furthermore, each first allocation information set and each second allocation information set define transmission resources for communications of each first user equipment (125M) and of each second user equipment (125M), respectively. In the heterogeneous wireless network (100), the at least one second cell (110) is at least …
