MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202511009521 A) filed by Rakuten Symphony, Inc. on February 05, 2025, for Early Timing Advance Acquisition For Layer 3 Measurements Based Conditional-Layer1/Layer2 Triggered Mobility.
Inventors include Chandrashekar, Subramanya; and Kamble, Vihang Gangaram.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: Embodiments of the disclosure describe a method for Timing Advance (TA) maintenance during Conditional Layer 1/Layer 2 Triggered Mobility (C-LTM). The method includes receiving, at a User Equipment (UE), a TA value associated with a Layer 1/Layer 2 Triggered Mobility (LTM) candidate gNodeB Distributed Unit (gNB-DU) cell from a candidate gNB-DU. The method further includes transmitting, by the UE, the TA value to a serving gNB-DU associated with the UE via an Uplink Medium Access Control-Control Element (UL MAC-CE) message to maintain the received TA value at both the UE and the serving gNB-DU. The method further includes determining, by the UE and/or network, whether the received TA value associated with the LTM candidate gNB-DU cell has expired. The method further includes initiating a re-acquisition of the TA value based on either a network-based decision-making timer or a UE-initiated request in response to determining that the received TA value has expired.
