Each traffic segment in a downlink or an uplink is associated with an acknowledgment segment in the uplink or downlink, respectively, in a fixed one-to-one manner. A base station uses the acknowledgment segments in the downlink to acknowledge the associated traffic segments successfully received in the uplink.
