Abstract:
A method of assembling a frame in an Orthogonal Frequency Division Multiple Access (OFDMA)-based communication system, wherein data packets to be transmitted from a broadcast station to a receiver are given a rectangular shape in terms of the two dimensions—time and frequency—of the OFDMA frame, and wherein the data packets are successively fitted into the OFDMA frame by way of a frame assembly scheduler, is characterized in that the filling process of the OFDMA frame is based on an ordered list of data structures that represent the current empty space within the OFDMA frame. Furthermore, a corresponding communication system is disclosed.
