摘要： A wireless network using network coding, and a method of adaptively adjusting buffering time in the wireless network, are provided. A communication method of a cross node in a wireless network, includes determining information associated with a number of hops between a source node and the cross node, and/or a number of hops between the cross node and a destination node. The method further includes adaptively adjusting a buffering time at the cross node based on the information. The method further includes buffering a packet received by the cross node based on the adjusted buffering time. The method further includes performing network coding of the buffered packet and another packet.

摘要： Provided is a physical layer network coding method and apparatus. A relay node determines reliabilities of symbols of nodes, based on a signal received from the plurality of nodes, and generates a transmission signal that maintains reliabilities of symbols that have high reliabilities and excludes components of symbols that have low reliabilities. The relay node generates the transmission signal that reduces an expected power of error, based on the received signal.
