摘要： Method and arrangement in a network entity for supporting link adaptation in a wireless communication system. The method comprises obtaining 204 one or more predicted parameters related to the quality of a radio link. The method further comprises measuring 206 one or more actual parameters, corresponding to the one or more predicted parameters. The method further comprises deriving 208 one or more error distributions based on the difference between the predicted and actual one or more parameters, from which error distributions a link adaptation margin estimate is derived, based on a predetermined radio link quality target. The link adaptation margin estimate is then used for supporting link adaptation for the radio link.

摘要： An antenna arrangement including at least two antenna functions arranged to cover a certain angular sector, each antenna function comprising a corresponding antenna port. The antenna arrangement is configured to perform: a first direction of arrival (DOA) estimation for a transmitting device at a first frequency, and a second DOA estimation for the transmitting device at a second frequency, wherein the second frequency has a larger magnitude than the first frequency, and wherein at least one second frequency grating lobe is apparent in the angular sector at the second frequency. The antenna arrangement is configured to: distinguish the at least one second frequency grating lobe from a second frequency main lobe using results from the first DOA estimation, and identify a pointing direction of the second frequency main lobe as a resulting DOA estimation. Related methods are also described.
