摘要： A method for operating a wireless terminal as an access point - access point terminal (2) - that connects a set of one or more client terminals (4) to an external network, wherein a schedule of absence periods is established during which said connected client terminals (4) are not allowed to transmit data to said access point terminal (2), wherein the absence periods together with corresponding presence periods are scheduled at regular intervals and have certain durations, is characterized in that an adaptation of the absence/presence periods' duration and/or interval parameters is executed on the basis of the bandwidth available in said external network and the amount of traffic transmitted between said access point terminal (2) and said connected client terminals (4). Furthermore, a corresponding wireless terminal is disclosed.

摘要： 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.
