The United States Patent and Trademark Office (USPTO) has granted Lenovo (Singapore) Pte. Ltd. patent US12581424B2, titled "Power spectrum density based configuration." This patent covers apparatuses, methods, and systems for configuring user equipment based on power spectrum density (PSD) requirements when transmitting control information (UCI) over a physical uplink control channel (PUCCH) in shared spectrum. The granted patent specifies a method involving transmitting UCI bits using multiple physical resource blocks (PRBs) and receiving a configuration message that indicates techniques to meet PUCCH PSD requirements, potentially involving larger sequence length generation or repetition across multiple RBs.

This patent grant is a routine event for a technology company and does not impose new regulatory obligations on other entities. Compliance officers should note this as a development in wireless communication technology, particularly concerning spectrum utilization and interference management. There are no immediate compliance actions required for regulated entities, and no penalties are associated with this patent grant itself.
