TECHNIQUE FOR DUAL-POLARIZED BEAMFORMING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18026390 titled 'TECHNIQUE FOR DUAL-POLARIZED BEAMFORMING

Simplified Explanation

- The patent application describes a technique for performing beamformed transmission and/or reception in wireless communication using an antenna array. - The technique involves using a first sub-array of antenna elements with a first polarization and a second sub-array of antenna elements with a second polarization that is orthogonal to the first polarization. - The method includes obtaining weight vectors for each sub-array that optimize a utility function. - The utility function includes a first term that depends on a function of the first weight vector and a function of the second weight vector. - The utility function also includes a second term that depends on either the first function or the second function. - The method further includes performing the beamformed transmission using the obtained weight vectors for each sub-array of antenna elements.


Original Abstract Submitted

A technique for performing a beamformed transmission and/or reception in a wireless communication using an antenna array comprising a first sub-array of first antenna elements each having a first polarization () and a second sub-array of second antenna elements each having a second polarization () that is orthogonal to the first polarization () is provided. As to a method aspect of the technique, a method for performing a beamformed transmission comprises or initiates a step of obtaining a first weight vector for the first sub-array and a second weight vector for the second sub-array. The first weight vector and the second weight vector optimize a utility function. The utility function comprises a first term depending on a first function of the first weight vector and on a second function of the second weight vector. The utility function further comprises a second term depending on either one of the first function and the second function. The method further comprises or initiates a step of performing the beamformed transmission using the obtained first weight vector for the first sub-array of antenna elements and the second weight vector for the second sub-array of antenna elements.
