ABSTRACT:
In order to increase the speed at which a determination is made as to which of a number of competing stations will occupy a particular block, the blocks are divided into a plurality of time slots and the various stations transmit probe signals into the time slots. Each station transmits its probe signal with a particular probability, with the probabilities preferably differing between respective stations. The number of occupied blocks in each frame can be counted to determine a degree of congestion, and the probe signal probabilities can be adjusted in accordance with the degree of congestion. Also if the degree of congestion is low, stations can transmit their packet signals directly without first transmitting probe signals, and the probe signal procedure will be followed thereafter only if a packet collision occurs.
