Trained data transmission for communication systems

Abstract

Various embodiments are described for a trained data transmission for communication systems. A training phase may include a first wireless station exchanging medium reservation messages with a second wireless station to reserve a medium and to select a data transmission parameter. The data transmission parameter may include a modulation scheme and a forward error correction (FEC) coding rate. At least one of the medium reservation messages may include a duration field indicating a duration for which the medium is reserved. A first data phase may include sending data from the first wireless station to the second wireless station according to the selected data transmission parameter. A second data phase may then be performed without first repeating the training phase. The second data phase may include transmitting data from the first wireless station to a second wireless station according to the data transmission parameter.
