The embodiments of the invention relate to a method for a first network node (NN 1 ) 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 (NN 1 ) 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 (DS 1 -2, DS2-2, DS3-2, NCS, DS1 1 R, DS21 R, DS31 R) by the second transmission (DT2) from the first network node (NN 1 ) 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 (NN 1 ). 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 (NN 1 ) to the second network node (NN2), transmitting from the second network node (NN2) the feedback parameter (FP) to the first network node (NN 1 ), and receiving at the second network node (NN2) the data (DS 1 -2, DS2-2, DS3-2, NCS, DS 1 1 R, DS21 R, DS31 R) by the second transmission (DT2) from the first network node (NN 1 ). The embodiments of the invention further relate to a first computer program, the first network node (NN 1 ), a second computer program and to the second network node (NN2). |
