ABSTRACT:
A method of controlling the transmission of a sequence of data symbols over a connection provided by a predetermined communication layer, which method comprises modifying the transmission by identifying (S41) a reference data symbol in the sequence of data symbols, dividing (S42) the data symbol following the reference data symbol in the sequence of data symbols into a sequence of new data units on the basis of a new data unit generation scheme, generating (S43) a new sender-side transmission record by mapping sender-side transmission status information associated with data units in an old sender-side transmission record onto the new data units in accordance with a predetermined mapping scheme for sender-side transmission records, generating (S44) a new receiver-side transmission record by mapping receiver-side transmission status information associated with data units in an old receiver-side transmission record onto the new data units in accordance with a predetermined mapping scheme for receiver-side transmission records, and performing (S45) the transmission control of the new data units on the basis of the new sender-side transmission records, and performing the reassembling of data symbols on the basis of the new receiver-side transmission record.
