Abstract
The method is used in a system comprising a central station (CS) coupled to each of a plurality of terminal stations (TS1-TSn), wherein the central station (CS) is enabled to transmit downstream frames (DS) to the terminal stations to allow the terminal stations to transfer upstream frames (US) to the central station in time slots assigned thereto by way of of access grant information (TEA1-TEA4) included in the downstream frames. The downstream frame (DS) is a superframe having a matrix structure with rows and columns, and a first portion and a second portion of the matrix structure is an overhead portion (S, TCB) and an information portion (ATM) respectively. The overhead portion includes the access grant information and the size of the overhead portion is flexibly adaptable. The central station and the terminal stations are adapted to send and to interpret the superframe.
