  • Patent number: 11336327
    Abstract: Techniques and apparatuses are described for enabling base stations (121, 122) to coordinate for canceling cross-link interference (380). The techniques and apparatuses described herein overcome challenges that a single base station (121) might otherwise face in trying to compensate a reception (131) by the base station (121) for cross-link interference (382) from a transmission (132) by another base station (122). The techniques and apparatuses described herein enable the base stations (121, 122) to form coordination sets to exchange information to enable the base stations (121, 122) to accurately reconstruct cross-link interference (380) and ultimately cancel the cross-link interference (380) to improve link quality.

  • Patent number: 11309634
    Abstract: A novel synthetic uniform circular array (SUCA) method for generating vortex electromagnetic (EM) wave carrying high orbital angular momentum (OAM) mode has the following steps. N antenna elements are placed radially to form a uniform circular array (UCA), where N is a positive integer. By rotating the array elements to various spatial locations, modifying their feeding phases, and superimposing the generated fields at various spatial locations, SUCA can beat the limit of space and configure more array elements to generate vortex electromagnetic (EM) waves carrying high mode OAMs. Meanwhile, due to the more synthetic array elements and smaller aperture than the traditional UCA, the purity of OAM mode is higher and it is more flexible to adjust the main lobe directions of these vortex waves carrying different OAM modes, and can generate vortex EM waves.

  • Patent number: 11303333
    Abstract: According to an aspect, there is provided an apparatus for performing beamforming optimization for a MIMO architecture. The apparatus maintains, in a database, channel state information of a plurality of radio channels comprising first and second order statistics. The apparatus calculates, separately for each of two or more remote radio units using an eigenbeamforming scheme, first sets of beamforming weights based on the second order statistics. Then, the apparatus performs, for each terminal device, single-user MIMO optimization between the two or more remote radio units to maximize a pre-defined metric, being a mutual information metric or signal-to-interference-plus-noise, based on first sets of beamforming weights and the first order statistics. The result, for each terminal device, is a second set of beamforming weights. The apparatus causes transmitting data using beams formed by applying both first and second sets of optimized beamforming weights at the two or more remote radio units.

  • Patent number: 11269052
    Abstract: A signal processing method is provided. First, at least one transmitted signal is output to at least one target, and the target reflects at least one reflected signal to receiving antennas, which then generate receiving signals upon receipt of the reflected signal. Next, the transmitted signal and each receiving signal are processed to generate processing signals. The processing signals are arranged in a form of matrix, to generate a channel coefficient matrix having M×N channel coefficient matrix blocks. Next, the channel coefficient matrix is divided into Ndivide×Mdivide secondary channel coefficient matrices, which are then substituted into a snapshot vector matrix equation to generate a snapshot vector matrix for calculating an angle of the target. The signal processing method can establish an optimal secondary channel coefficient matrix arrangement by using a special signal preprocessing manner, to improve the resolution and accuracy of the estimated angle parameter of the target.
