Abstract
The present disclosure relates to method for link adaptation in a first network unit of a wireless communication system. The first network unit comprises one or multiple antennas adapted for data transmission to and data reception from at least one second network unit in said system. The method adapts, in response to interference experienced at the site of the first network unit, transmission parameters for data transmissions from said second network unit to said first network unit. The method comprises determining values equivalent to the Hermitian inner products between whitened vector channels associated with the individual combinations of antennas of said second network unit transmitting to said first network unit. The method further comprises steps of mapping the determined values into a data element and providing the data element as feedback information to said second network unit.
