Method and apparatus for transmitting digital data packets on a wireless channel

In a method and apparatus for transmitting digital data packets from a station (12,14) in a wireless communication system, successive time intervals (T) are established and a packet is transmitted only if the transmission thereof does not cause a predetermined average power value (Po) to be exceeded for the current time interval. For each packet an appropriate power value is ascertained from a data base (62), in dependence on the particular destination station to which the packet is to be transmitted. For each time interval (T) a maximum energy value (Io) is decremented in accordance with the energy utilized for transmitting each packet, and a packet is transmitted only if there is sufficient energy remaining to transmit the product during the current time interval (T).
