Company patents

SoftBank Corp.

SoftBank Corp. surprisingly shows a significant, albeit fluctuating, focus on communication technologies, with Wireless Networks representing nearly 30% of its portfolio and experiencing a massive 575.0% YoY growth in 2024 before a decline. While Computer Vision saw a 150.0% YoY increase in 2024, its complete absence of patents so far in 2026 suggests a shifting priority, contrasting with an emerging focus on Animal Husbandry / Fishing, which saw a 100.0% YoY growth in 2026.

Interference suppression apparatus, system, inter-base station control method and program

Filed:2023-08-08Pub:2026-01-13
Applicant:SoftBank Corp.

In a HetNet configuration in which plural small-sized second cells are disposed in a first cell, an amount of signal processing for suppressing interference from other cells with respect to a reception signal on an uplink line of a base station of any one of the cells is reduced. An interference suppression apparatus creates a first propagation-path response matrix including a plurality of first propagation-path responses from terminals of plural second cells to a first base station, creates a second propagation-path response matrix including a plurality of second propagation-path responses from terminals of plural second cells to plural second base stations, calculates plural reception weights based on the first propagation-path response matrix and an inverse matrix of the second propagation-path response matrix, and suppresses interference to an uplink of the first base station, based on a reception signal of the first base station, reception signals of the plural second base stations and the plural reception weights. The interference suppression apparatus sets to zero a second propagation-path response having an electric power of magnitude equal to or less than a predetermined threshold value or less than the threshold value among the plurality of the second propagation-path responses included in the second propagation-path response matrix before calculating the inverse matrix.
