The invention relates to a method of transmission of information in packet form in a channel between a number of transmitter/receiver stations. According to the method, information is transmitted between the stations using two access methods. The first access method listens to the channel and transmits on the channel after a certain time after the channel has been confirmed to be free. The second access method uses time division. According to the invention, these two access methods are combined in such a manner that a transmission (TC1) using the first access method with acknowledgement request (PF) is followed by acknowledgement transmissions (KV1-KVn) using the second, time division access method, and that acknowledgement information is always received in the transmitter station irrespective of the level of interference on the channel.
