MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202618071645 A) filed by Interdigital Patent Holdings, Inc. on June 09, 2026, for Methods And Systems For Efficient Uplink (ul) Synchronization Maintenance With A Deactivated Secondary Cell Group (scg).
Inventors include Teyeb, Oumer; Freda, Martino; Deenoo, Yugeswar Number; and Comsa, Virgil.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A wireless transmit/receive unit (WTRU) may receive indication information indicating an uplink (UL) configuration and one or more triggering conditions for transmission of UL signals. Based on reception of a deactivation command or fulfillment of a condition for WTRU-triggered deactivation of a secondary cell 10 group (SCG), the WTRU may deactivate the SCG. Based on the UL configuration and the fulfillment of the one or more triggering conditions, the WTRU may transmit the UL signals via the SCG. The WTRU may receive, via a master cell group (MCG), an in-synch or out-of-synch indication for the SCG. Based on the reception of the out-of-synch indication including a timing advance (TA) delta 15 value, the WTRU may update a UL TA towards the SCG based on the TA delta value. Using the updated UL TA towards the SCG, the WTRU may transmit one or more subsequent UL signals via the SCG.
