Patent ID: 8589586

Claim:
A communication device arranged to transmit a data segment over an air interface within a wireless communication network, the communication device comprising: a processor; transmission management logic, implemented by the processor, for determining a sequence number of a data segment to be transmitted, wherein the transmission management logic is operable to: compare the sequence number of the data segment to be transmitted with at least one pending sequence number of a previous data segment including at least one data segment previously transmitted over the air interface and for which acknowledgement signaling indicating whether transmission of the data segment has succeeded or failed has not yet been received, and, based on the comparison, discard the data segment to be transmitted in response to the sequence number of the data segment to be transmitted matching the at least one pending sequence number of the previous data segment; and add the sequence number of the data segment to be transmitted to the at least one pending sequence number and transmit the data segment over the interface in response to the sequence number of the data segment to be transmitted not matching the at least one pending sequence number.
