Abstract:
A method for estimating channel state information (CSI) for a communication channel is disclosed. Theoretical channel capacities are calculated using combinations of rank indicator (RI) and precoding matrix index (PMI) values. A number of these theoretical channel capacities are selected and used for determining an optimum combination of channel quality indicator (CQI) values, RI values and PMI values. This combination of values is subsequently transmitted as CSI.
