There is provided a powerline network (202,220) that includes a number of stations (A,B,C,D) including a central coordinator (Cco1) for coordinating transmissions of each of the stations (A,B,C,D). The central coordinator (Cco1) is configurable to transmit a beacon at an interval (402) based on a phase of a powerline cycle (404). The interval of the beacon (402) can be substantially equal to two periods of the powerline cycle (404). The interval of the beacon (402) includes a reserved region (410) including a persistent allocation region (412) and a non-persistent allocation region (414). The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period (402) and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period (402). The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.
