1. A method of adaptive uplink/downlink timeslot assignment, implemented in a Node-B, comprising:

  • determining at least one of a potentially interfering cell which potentially interferes with a particular cell;

    eliminating a timeslot for uplink communication, on a condition that a first one of the potentially interfering cells uses that timeslot for downlink communications;

    eliminating a timeslot for downlink communication for at least one user on a condition that a dynamic interference measurement in that timeslot as measured exceeds a predetermined threshold for the at least one user;

    assigning a timeslot to an uplink communication of the particular cell using timeslots not eliminated for uplink communication; and

    assigning a timeslot to a downlink communication of the particular cell to each user using timeslots not eliminated for downlink communication with respect to that user, on a condition that the dynamic interference measurement in that timeslot as measured does not exceed the predetermined threshold.
