Fading on a data link prevents a mobile station from acknowledging a received base station poll message. Responsive thereto, the data link is transitioned to an unacknowledged mode of operation. A group of frames of a data communication are then transmitted to the mobile station with no base station expectation of receiving a mobile station acknowledgment. Following group frame transmission, the data link is transitioned back to acknowledged mode of operation. To insure delivery of the data communication, the sent frames a queued (stored) by the base station until such time as a delivery confirmation with respect to the group of frames can be obtained. |
