Summary

The USPTO has published a new patent application from HUAWEI Technologies Co., Ltd. for a communication method and apparatus designed to reduce uplink signal interference. The patent aims to improve communication performance by managing virtual PCI conflicts.

What changed

This document is a publication of a new patent application (US20260088959A1) filed by HUAWEI Technologies Co., Ltd. The patent describes a communication method and apparatus intended to reduce uplink signal interference caused by PCI modulo conflicts, thereby enhancing communication performance. The core innovation involves a second device sending information to obtain a virtual PCI for a first cell, which is distinct from the cell's actual PCI. The first device then uses this virtual PCI to send a reference signal, which is received by the second device.

As this is a patent application, it does not impose direct regulatory obligations or compliance deadlines on entities. However, it signifies a technological advancement in telecommunications, particularly in signal interference management. Companies operating in the networking and telecommunications sectors, especially those utilizing similar technologies or developing competing solutions, should be aware of this patent filing as it may impact future product development and intellectual property strategies.
