Disclosed are improved retransmission schemes. In one embodiment, a retransmission method includes: receiving, at a protocol layer in a receiver, a data block transmitted from a protocol layer in a transmitter; determining that it is not possible to decode the data block; determining that it is not probable that the data block can be decoded; signaling, from the protocol layer in the receiver, to the protocol layer in the transmitter first feedback information indicating that the data block was received; and signaling, from the protocol layer in the receiver, to the protocol layer in the transmitter second feedback information including information related to the reception time of the data block and indicating that the data block is aborted.
