摘要： A method of operating a communication system comprises sending a frame by an access node to a wireless device where the frame comprises a packet. A counter is initialized and a timer for each frame is initiated. The method continues with the access node determining if a response associated with the packet is received before the expiration of the timer. If the response is received prior to the expiration of the timer, the counter and the timer are reset. If a response is not received prior to the expiration of the timer, the counter is incremented. Upon the counter meeting a criteria of a certain quantity of lost packets, the access node performs a synchronization process.

摘要： A method of operating a communication system comprises establishing a wireless device release time interval for a wireless device release timer at an access node upon establishing an initial network connection between a wireless device and the access node. An initial synchronization process is performed between the wireless device and the access node. The method continues with the access node sending an unsolicited synchronization message to the wireless device and starting the wireless device release timer. A second synchronization process is performed and upon successful completion of the second synchronization process, a success status synchronization response message is sent by the access node to the wireless device. The access node receives a synchronization confirmation message from the wireless device that comprises an identifier corresponding to the identity of the wireless device and upon receiving the confirmation message, the access node cancels the wireless device release timer.

摘要： An apparatus and method of configuring a number of retransmissions for an automatic repeat request (ARQ) scheme (e.g., hybrid ARQ) includes configuring one or more first maximum retransmission numbers based on respective one or more first predetermined values and independent of a second maximum retransmission number. The first maximum retransmission numbers may indicate a maximum number of retransmissions related to respective service flows operational with the base station. The second maximum retransmission number may indicate a maximum number of retransmissions related to control messages transmitted in the wireless network, and may be configured based on a second predetermined value. The configuration of the first maximum retransmission numbers may include the maximum retransmissions numbers associated with a specific user in communication with the base station. Further, at least one of the first maximum retransmission numbers of a particular user may be reconfigured to a third predetermined value.
