Abstract
A method for generating acknowledgement messages in a data transmission system having a receiver for receiving datagrams and being capable of determining which of a series of datagrams have been incorrectly received, the method comprising generating a plurality of a data units, each data unit comprising: a status bit indicative of the status of the data unit; and a plurality of spacing bits together forming a binary representation of a number at least partially indicative of the spacing between one incorrectly received datagram and a succeeding incorrectly received datagram. Apparatus for carrying out various aspects of the methods are also provided.
Claims23
An apparatus comprising:
- a transmitter configured to receive an acknowledgment message comprising a plurality of data units, each data unit comprising a status bit indicative of a status of the data unit and a plurality of spacing bits, wherein the plurality of spacing bits from the plurality of data units together form a binary number, the binary number being the spacing between one incorrectly received datagram and a succeeding incorrectly received datagram and to determine from the acknowledgement message which of a plurality of datagrams have been incorrectly received.
An apparatus for determining which of a series of datagrams have been incorrectly received, the apparatus comprising:
- means for receiving an acknowledgement message comprising a plurality of data units, each data unit comprising a status bit indicative of a status of the data unit and a plurality of spacing bits, wherein the plurality of spacing bits from the plurality of data units together form a binary number, the binary number being the space in between one incorrectly received datagram and a succeeding incorrectly receiving datagram;
- and
- means for determining from the acknowledgement message which of a plurality of datagrams have been incorrectly received.
A method comprising:
- receiving an acknowledgment message comprising a plurality of data units, each data unit comprising a status bit indicative of a status of the data unit and a plurality of spacing bits, wherein the plurality of spacing bits from the plurality of data units together form a binary number, the binary number being the spacing between one incorrectly received datagram and a succeeding incorrectly received datagram;
- and
- determining from the acknowledgement message which of a plurality of datagrams have been incorrectly received.
