Abstract
An approach for managing data transmissions from multiple sources using a common channel addresses the problem of interference caused by two or more sources transmitting simultaneously. In one embodiment, the communication system provides a state of the channel, for example, an indication of the recent or current channel state such as interference level. Before transmitting, a transmitter station buffers blocks of data and selects a transmission mode for use in transmitting at least one of the buffered data blocks as a function of the buffered data sets and the indication of the recent channel state (interference). More specific embodiments are directed to, among other aspects, use of algorithms for evaluating the channel state and processing the transmissions using various types of transmission modes including, for example, setting the power level, modulation scheme, access point, coding scheme, and combinations of these adjustable parameters.
