Abstract:
1. A method of controlling a stall avoidance in a reordering buffer of a communication device using at least one timer comprising: (a) receiving a plurality of MAC-hs PDUs by the reordering buffer of a MAC-hs sub-layer of a medium access control (MAC) layer; (b) placing each MAC-hs PDU in the reordering buffer at a place indicated by each transmission sequence number (TSN) of each MAC-hs PDU; (c) starting the at least one timer when a MAC-hs PDU is correctly received and the TSN of the MAC-hs PDU is higher than the next expected TSN if the at least one timer is not active, (d) delivering to a higher entity all correctly received MAC-hs PDUs up to and including TSN-1 and all correctly received MAC-hs PDUs up to the next not received MAC-hs PDU when the at least one timer expires; and (e) starting the at least one timer for a MAC-hs PDU having the highest TSN among those of the MAC-hs PDUs that can not be delivered to the higher entity.
