Feedback-based broadcasting of network coded packets with sidelink
Abstract:
Methods, systems, and devices for wireless communications are described. A network node may transmit, to a set of user equipment (UE), a set of network encoded packets generated using a set of packets. A UE of the set of UEs may receive subsets of network encoded packets from the network node and from UEs of the set of UEs forwarding network encoded packets. The UE may decode the subsets of network encoded packets and may determine a set of successfully decoded packets. The UE may transmit feedback to the network node that indicates successfully received or decoded packets. The network node may receive the feedback and may determine a subset of the set of packets that was successfully decoded for each UE providing the feedback. The network node may generate an updated set of network encoded packets and may transmit the updated set to the set of UEs.
