ABSTRACT:
In a cordless communications system, such as DECT, data is transmitted to or from a data terminal in an assigned channel in each TDMA frame. In order to accommodate data terminals having lower data rates than the capacity of the channel, such a data terminal accumulates its data during several frames in a buffer store until the accumulated data corresponds to the channel capacity, and is then transmitted in the frame in which that occurs. In order to utilize such interruptions in transmission from a plurality of low rate data terminals, the system control terminal treats each successive sequence of a predetermined number of frames (FR0 to FR15) as a multiframe, and transmissions from low rate data terminals are assigned to multiplexed frames which minimize the number of unoccupied channels in each multiframe.
