Sony patents method to reduce signal interference between cell towers

Patent drawing from the official filing.

Sony has filed a patent application for a method that helps wireless network equipment manage signal interference. The system works by having towers share their interference priority levels with nearby towers. Based on these shared levels, the equipment adjusts its transmission settings to minimize disruption to other parts of the network.

Why it mattersThis filing focuses on improving the efficiency and stability of wireless networks by allowing infrastructure to coordinate better, which could lead to more reliable connections for users.

In the filing’s own words

A method for controlling cross-link interference (CLI) in a wireless communications network is disclosed. The method involves detecting a CLI priority indicator from other network infrastructure, which indicates their CLI priority level. Based on this, the method determines whether a wireless transmission should occur between the infrastructure equipment and a device within its coverage area. By comparing the CLI priority levels, the method identifies the necessary modifications to transmission parameters to reduce interference with other infrastructure equipment. The transmission parameters are then adjusted accordingly to mitigate the interference.

What exactly they claim (claim 1)

1. A method of controlling cross-link interference, CLI, by infrastructure equipment of a wireless communications network, the method comprising detecting a CLI priority indicator from other infrastructure equipment of the wireless communications network, the CLI priority indicator comprising an indication of a CLI priority level of the other infrastructure equipment, determining that a wireless transmission is to be communicated between the infrastructure equipment and a communications device in a coverage area provided by the infrastructure equipment, determining, based on a comparison of a CLI priority level of the infrastructure equipment and the CLI priority level of the other infrastructure equipment indicated by the CLI priority indicator, an extent to which one or more transmission parameters of the wireless transmission should be modified to reduce interference caused by the wireless transmission at the other infrastructure equipment, and modifying the one or more transmission parameters of the wireless transmission in accordance with the determined extent of modification.
