Abstract
In a wireless communications system, a data link layer and a medium access control layer are connected to each other by data and control paths, where the data path is operable to exchange frames between the data link layer and the medium access control layer and the control path is operable to exchange control messages between the data link layer and the medium access control layer. The data link layer includes a queue for storing frames received from the medium access control layer and the medium access control layer includes a queue for storing frames received from the data link layer. The data link layer is adapted to pass new data frames from a higher layer relative to the data link layer into the data link layer queue and to suspend a retransmission timer upon a congestion message received from the medium access control layer, the congestion message being responsive to a level of stored frames in the medium access control queue.
