Abstract
Keeping track of potential receive window positions in a communication system can prevent the receive window from moving from the proper potential positions, thereby reducing the probability of incorrect positions of the receive window. For example, a receive window can be updated by comparing the block number of a received block to a receive window; if the block number of the received block is outside the receive window, discarding the received block; if the block number of the received block is inside the receive window, retaining the received block; and determining an updated receive window that has a reduced size that excludes received blocks having block numbers that are not permitted according to the sequence of block numbers.
