Qualcomm Patent for Vehicular Platoon Wireless Communication
Summary
The USPTO has granted a patent to QUALCOMM Incorporated for a distance-based NACK procedure in vehicular platoons. This patent covers methods and systems for wireless communication between vehicles in a platoon, focusing on how vehicles adjust their communication protocols based on their role (primary or secondary) within the formation.
What changed
The United States Patent and Trademark Office (USPTO) has granted patent US12587320B2 to QUALCOMM Incorporated for a novel distance-based NACK (Negative Acknowledgement) procedure designed for wireless communications within vehicular platoons. The patent details methods and systems where a user equipment (UE), such as a vehicle, receives an indication of a formation change within its associated platoon. Based on this change, the UE determines whether it will operate as a primary vehicle or a secondary vehicle and adopts a corresponding distance-based feedback procedure.
This patent grant, while not imposing immediate regulatory obligations on other entities, establishes intellectual property rights for QUALCOMM in the area of vehicular communication protocols. Companies developing or deploying vehicle-to-vehicle (V2V) communication systems, particularly those involving platooning or coordinated movements, should be aware of this patent. Future product development or licensing agreements may need to consider this granted patent to avoid infringement. The filing date was July 21, 2021, and the patent is effective March 24, 2026.

Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE), such as a vehicle UE may receive an indication of a change in a formation of a vehicle grouping, such as a platoon, with which the UE is associated, the vehicle grouping including a plurality of vehicles moving as a group based on sidelink communications between members of the group. The UE may determine a distance-based feedback procedure to be used by the UE based on whether the UE is, as a result of the change in the formation, a primary vehicle in the vehicle grouping or a secondary vehicle that is responsive to one or more primary vehicles in the vehicle grouping, and may operate in accordance with the distance-based feedback procedure.
