METHOD FOR A FIRST NETWORK NODE FOR TRANSMITTING OR RETRANSMITTING DATA TO A SECOND NETWORK NODE AND FIRST NETWORK NODE THEREOF AND METHOD FOR A SECOND NETWORK NODE FOR RECEIVING DATA TRANSMITTED OR RETRANSMITTED FROM A FIRST NETWORK NODE AND SECOND NETWORK NODE THEREOF

摘要

The embodiments of the invention relate to a method for a first network node (NN1) for transmitting or retransmitting data to a second network node (NN2). The method contains receiving at the first network node (NN1) from the second network node (NN2) a feedback parameter (FP) in response to a first transmission (DT1) of at least two data segments (DS1-1, DS2-1, DS3-1) of a data packet. The feedback parameter (FP) is a number of counted data segments of the at least two data segments (DS1-1, DS2-1, DS3-1) incorrectly received or lost or correctly received at the second network node (NN2) by the first transmission (DT1). The method further contains determining at the first network node (NN1) for a second transmission (DT2) to the second network node (NN2) the data (DS1-2, DS2-2, DS3-2, NCS, DS1 1 R, DS21 R, DS31 R) as a function of the feedback parameter (FP) and transmitting or retransmitting the data (DS1-2, DS2-2, DS3-2, NCS, DS1 1 R, DS21 R, DS31 R) by the second transmission (DT2) from the first network node (NN1) to the second network node (NN2). The embodiments of the invention further relate to a further method for the second network node (NN2) for receiving data transmitted or retransmitted from the first network node (NN1). The further method (MET-NN2) contains determining at the second network node (NN2) the feedback parameter (FP) in response to the first transmission (DT1) from the first network node (NN1) to the second network node (NN2), transmitting from the second network node (NN2) the feedback parameter (FP) to the first network node (NN1), and receiving at the second network node (NN2) the data (DS1-2, DS2-2, DS3-2, NCS, DS1 1 R, DS21 R, DS31 R) by the second transmission (DT2) from the first network node (NN1). The embodiments of the invention further relate to a first computer program, the first network node (NN1), a second computer program and to the second network node (NN2).

1. A method for a first network node for transmitting or retransmitting data to a second network node, said method comprising:
receiving a feedback parameter at said first network node from said second network node in response to a first transmission of at least two data segments of a data packet from said first network node to said second network node, determining at said first network node for a second transmission from said first network node to said second network node said data as a function of said feedback parameter, and transmitting or retransmitting said data by said second transmission from said first network node to said second network node,wherein said feedback parameter is a number of counted data segments of said at least two data segments incorrectly received or lost at said second network node or a number of counted data segments of said at least two data segments correctly received at said second network node by said first transmission.
