Abstract
Fremgangsmåter og apparater presenteres for bestemmelse av om tilbakekopling eller tilbakeføring skal brukes og størrelsen av eventuell slik tilbakekopling, i forbindelse med informasjon som er basert på kanalressurser og som gjelder såkalte "egenstråler", dvs. de maksima som et antennesystems retningskarakteristikk fremviser, idet disse maksima er i samme retning som en karakteristisk kovariansmatrise tilsier. I tillegg presenteres fremgangsmåter og apparater for bestemmelse om eventuell tilbakekopling når det gjelder slik egenstråleinformasjon, men basert på kanalinformasjon og endringer i denne.Methods and apparatus are presented for determining whether feedback or feedback is to be used and the magnitude of any such feedback, in conjunction with information based on channel resources and relating to so-called "intrinsic rays", i.e., the maxima exhibited by the directional characteristics of an antenna system, these maxima. is in the same direction as a characteristic covariance matrix indicates. In addition, methods and apparatus for determining possible feedback regarding such radiation information are presented, but based on channel information and changes therein.
