Abstract:
1. A method of operating a communication system, comprising: initiating a communication transmission from an access node to a wireless device; sending a frame by the access node to the wireless device, wherein the frame comprises at least two packets and wherein each of the at least two packets require a response from the wireless device; initializing a counter at the access node when the frame is sent to the wireless device; initiating a timer for each packet of the at least two packets at the access node when the frame is sent to the wireless device; incrementing the counter when at least one timer expires before receiving the response associated with the at least two packets from the wireless device and resetting the timer and the counter when a response associated with a prior frame is received prior to the expiration of the at least one timer; performing a synchronization process between the access node and the wireless device when the counter meets a criteria, wherein the criteria is indicative of a maximum number of packets lost allotted between the access node and the wireless device and is negotiated between the access node and the wireless device; and stopping the communication transmission from the access node when the counter meets the criteria.
