If own station detects that a slot S2 previously reserved for own transmission has been occupied by another station when transmitting a message at a current slot S3, the own station sets the occupied slot to a time-out value of zero S0 upon transmitting the message at the current slot S3. At the same time, the own station re-reserves a new slot S5 within an SI in a succeeding frame so that transmission from the own station at the new slot S5 does not conflict with transmission from the other station at the occupied slot, now reserved by other station as slot A.
