Techniques for efficiently sending side information to support network coding in a wireless network are disclosed. A node may send a subset of packet identifiers (IDs) for received packets in order to reduce signaling overhead in support of network coding operations. In one design, a node obtains a plurality of received packets, with each received packet being generated based on at least one base packet in a set of base packets. The node determines a reduced set of base packet IDs for the received packets. The reduced set may be a subset of an overall set including base packet IDs of all base packets for each of the received packets. The node sends information conveying the reduced set of base packet IDs, receives a network-coded packet generated based on the sent information, and recovers a base packet intended for the node based on the network-coded packet. |
