Radio Access Network Signaling for FEC PDU Marking
Summary
USPTO published patent application US20260113148A1 by inventors Mickael MONDET, Prasada Veera Reddy KADIRI, Diana MAAMARI, Hyun Yong LEE, and Sebastian SPEICHER, covering methods and systems for wireless communications involving radio access network (RAN) signaling for forward error correction (FEC) awareness and packet data unit (PDU) set information marking. The application describes techniques where a first RAN node receives, from a second node, an indication of an FEC content ratio for a data traffic flow, and transmits an FEC report based on the number of PDUs discarded from a distributed unit buffer. The application was filed on October 18, 2024, under Application No. 18920748, and classified under CPC H04L 1/0076 and H04W 28/0268.
“A first radio access network (RAN) node may receive, from a second node, a first indication of a forward error correction (FEC) content ratio for a data traffic flow.”
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.
What changed
USPTO published patent application US20260113148A1 disclosing methods, systems, and devices for wireless communications involving radio access network (RAN) signaling for forward error correction (FEC) awareness and packet data unit (PDU) set information marking. The application describes a first RAN node that receives, from a second node, an indication of an FEC content ratio for a data traffic flow including one or more PDU sets associated with a quality of service (QoS) flow. The first RAN node then transmits an FEC report indicating the number of PDUs discarded from a buffer of a distributed unit (DU) associated with the first RAN node, with the report being based on the FEC content ratio.
Parties involved in wireless telecommunications equipment development, network infrastructure manufacturing, and 5G/6G standards development may find this patent application relevant for understanding potential approaches to FEC management and QoS flow handling in next-generation RAN architectures. Inventors Mickael MONDET, Prasada Veera Reddy KADIRI, Diana MAAMARI, Hyun Yong LEE, and Sebastian SPEICHER filed the application on October 18, 2024.

Abstract
Methods, systems, and devices for wireless communications are described. A first radio access network (RAN) node may receive, from a second node, a first indication of a forward error correction (FEC) content ratio for a data traffic flow. The data traffic flow may include one or more packet data unit (PDU) sets associated with a quality of service (QoS) flow. The first RAN node may transmit an FEC report that indicates a number of PDUs, of the one or more PDU sets, that were discarded from a buffer of a distributed unit (DU) associated with the first RAN node. The FEC report may be based on the FEC content ratio.
