Abstract
It is disclosed a client node, a first network node, a second network node, and methods therefore, for enabling forward error correction, FEC, of data. In uplink, the client node is adapted to transmit a lightweight FEC packet, enabling to save radio resources. The first network node is adapted to calculate a payload for the FEC packet and to append the payload to a “lightweight” FEC packet, and to transmit the thus modified FEC packet to an endpoint of the uplink. In the downlink, the second network node may be adapted to determine whether a received FEC packet is redundant or not, and is adapted not to transmit it as is, to an endpoint client node, if the FEC packet is redundant, enabling saving radio resources.
