1. A method for allocating a number of contention mini-slots for a current contention cycle as part of a Medium Access Control (MAC) protocol, said MAC protocol having a MAC protocol state equal to one of a normal state and a collision resolution state, the method comprising the steps of:

  • determining an aggregate feedback state for a previous contention cycle based on individual feedback states for a number of contention mini-slots allocated in the previous contention cycle, wherein the individual feedback state for each of the number of contention mini-slots represents the result of contention for the contention mini-slot, and wherein the aggregate feedback state is equal to one of IDLE, COLLISION, and SUCCESS;

    updating a collision resolution interval; and

    determining an allocation of contention mini-slots for the current contention cycle based on the aggregate feedback state and the updated collision resolution interval.
