Abstract
A master station and at least one slave station are connected by radio channels. Each slave station transmits data to the master station by time division multiple access. A first circuit equally divides a prescribed area into at least two sub-areas. The prescribed are is defined in a burst signal for transmitting data from each slave station to the master station, the prescribed area being provided for an arrangement of message signals which are sent from at least one terminal connected to the slave station. The first circuit also arranges a message signal in each sub-area. A second circuit generates a burst signal in which at least a control signal and a channel quality monitoring signal are arranged. The control signal and the channel quality monitoring signal are generated in the area peripheral to each sub-area in which a message signal is arranged. The prescribed area in the burst signal may be an area corresponding to a data quantity of 64 kbps in transmission speed. The data quantity of the message signal arranged in that area corresponds to data of 32 kbps, 16 kbps or 8 kbps in transmission speed.
