  • Method to optimize the power assignment of user streams transmitted from base stations in coordinated base station transmission systems
    Patent number: 9112548
    Abstract: A method to optimize the power assignment of user streams transmitted from base stations in coordinated base station transmission systems. In the method of the invention said CBST systems employ block diagonalization techniques and are deployed in MIMO-OFDM scenarios, and it further comprises using a new waterfilling technique which provides a performance very close to the theoretical ideal but with a reduced computational complexity.
    Type: Grant
