METHOD USING RELIABILITY MEASURES CORRESPONDING TO CHANNEL PARAMETERS IN ADAPTIVE SCHEDULING

摘要

The present invention relates to a method and arrangement for improving the channel state condition information that is provided between transmitter and receiver units in a wireless communication system. The present invention introduces a statistical measure, e.g. an uncertainty value of a quantity or its prediction value, for parameters that describe a communication channel and define said measure under consideration of possible impacts on said channel. A reliability measure is provided for the communication channel from a transmitter unit to a receiver unit representing an estimation of appropriate channel parameters. The reliability measure is either retrieved at the receiver unit and based on direct channel observations or indirectly retrieved at the transmitter unit based on feedback information or conclusions from the behaviour of the reverse channel. The present invention can be implemented either in a radio base station or in a user equipment of a wireless communication system.
