Abstract: Embodiments allow a station to determine which of a plurality of spatial beams is best suited for communicating with user equipment (UE). Some embodiments overlay spatial multiplexing in a way that provides support for UE without changing existing signaling schemes. In these embodiments, different messages, each designed to provoke different behavior in the UE, are transmitted on different spatial beams. The station then observes the behavior to determine which beam is most suited for the UE. Other embodiments design new signaling schemes to effectively allow UE supporting the schemes to identify which beam is most suited for communication. A single reference signal is scrambled with one of a plurality of indexing sequences, and each is transmitted on a different spatial beam. The UE performs a channel quality estimate for each scrambled signal and determines the index best suited for communication. The index may then be transmitted to the station.

Abstract: 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.
