Abstract:
1. A communication terminal comprising: a receiver configured to receive a signal from a sender terminal; a signal analyzer configured to determine one or more quality parameters of the received signal; an adaptation information generator configured to produce adaptation information based upon said signal quality parameters; a transmitter for transmitting data, wherein said data includes the adaptation information and said transmitter is arranged to transmit said adaptation information using one bit of the data included in a header of each of one of more packets of data to be transmitted; a modulation scheme adapter responsive to received adaptation information included in said received signal, and configured to determine a modulation scheme for transmission of data from the terminal; and a modulator configured to modulate said data according to the determined modulation scheme prior to remission, wherein the adaptation information from two consecutive transmissions are added together in determining said modulation scheme.
