Abstract
According to exemplary embodiments of the present invention, each transmitted data block is assigned the current value of NextPollToBeSent. When an acknowledgement message is received, a valid ACK/NACK is contained for all data blocks that have been assigned index NextAckDue. This technique of tying data blocks to a particular polling request copes well when multiple retransmissions of a data block are necessary, and when polling requests/acknowledgement messages are lost.
