Preamble Signaling for Multi-Access Point Coordinated Beamforming Using Combination Codes
Summary
USPTO has published patent application US20260113086A1 by Avago Technologies International Sales Pte. Limited for a preamble signaling system enabling multi-access point coordinated beamforming in wireless local area networks. The system uses BSS color indications in preamble common fields and ordered user fields to trigger client devices to process network packets for coordinated beamforming communication. The application was filed on April 29, 2025 and published on April 23, 2026.
“The first AP can be configured to include, into the common field of the preamble, an indication of one or more BSS colors associated with the first AP and the second AP.”
About this source
USPTO classification H04L covers transmission of digital information: network protocols, modulation schemes, wireless signal processing, coding, encryption in transit, and multiplexing. With 5G, 6G, and satellite internet driving new filings, H04L is one of the largest active patent classes. Every newly published application in H04L lands in this feed, around 215 a month. Applications publish 18 months after filing, so this feed reveals what MediaTek, Qualcomm, Ericsson, Samsung, Huawei, and dozens of smaller companies were working on in the prior year and a half. Watch this if you compete in networking hardware, advise telecoms on IP strategy, or scout acquisition targets in wireless infrastructure.

Abstract
At least one aspect of the technical solutions is directed to a system. The system can include a first access point (AP) configured to generate a preamble for a network packet of a wireless local area network (WLAN). The first AP can be configured to include, into the common field of the preamble, an indication of one or more BSS colors associated with the first AP and the second AP. The first AP can be configured to order the plurality of user fields of the preamble into a first subset of user fields associated with a first one of the first AP. The first AP can be configured to transmit the preamble to a client device of the plurality of client devices to trigger the client device to process the network packet for coordinated beamforming (CBF) communication based on the order of the plurality of user fields.
