ABSTRACT:
A contention resolution system and method are disclosed that can be used in a station having a data packet to send in a wireless telecommunications network. After a predetermined maximum number of selection rounds, it is determined whether the station is authorized to send the packet. In each of the rounds, a value of a binary random variable is drawn, which represents authorization or prohibition, to send the packet during the round. The probability of the binary random variable value assuming a predetermined value is adjusted taking into account authorizations and prohibitions to send the packet obtained by the station during preceding selection rounds.
