  • Handling of impaired antenna branch
    Patent number: 12009874
    Abstract: There is provided mechanisms for handling an impaired antenna branch at a radio transceiver device. The radio transceiver device includes a plurality of antenna branches. Channel information is correlated among the respective antenna branches according to a correlation relation. A method is performed by a network node. The method includes obtaining an indication that at least one of the antenna branches at the radio transceiver device is impaired. The method includes, in response thereto obtaining channel information for each of the non-impaired antenna branches at the radio transceiver device. The method includes estimating channel information for each of the at least one impaired antenna branch using the obtained channel information and the correlation relation.
