  • Method and apparatus for multi-antenna communication
    Patent number: 11736179
    Abstract: Various embodiments of the present disclosure provide a method for multi-antenna transmission. The method which may be performed by a communication device comprises determining first correlation information in response to interference to data on a first subset of multiple antenna branches of the communication device. The first correlation information may indicate at least correlation between the data on the first subset of the multiple antenna branches and data on a second subset of the multiple antenna branches which is not affected by interference. The method further comprises correcting the data on the first subset of the multiple antenna branches, based at least in part on the first correlation information.
