MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202647074515 A) filed by Qualcomm Incorporated on June 16, 2026, for Transmission Configuration Indication State Application Timing After Lower-Layer Triggered Mobility Cell Switch.
Inventors include Sung, Doohyun; Nam, Wooseok; Park, Changhwan; Zhou, Yan; and Damnjanovic, Jelena.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a lower-layer triggered mobility (LTM) cell switch command that indicates a transmission configuration indication (TCI) state and a first synchronization signal block (SSB) index, wherein the TCI state indicated in the LTM cell switch command is associated with a second SSB index that differs from the first SSB index. The UE may communicate using a beam associated with the first SSB index until a first time, wherein the first time is related to a random access channel (RACH) procedure triggered by the LTM cell switch command. The UE may communicate using the TCI state associated with the second SSB index starting at a second time, wherein the second time is related to the first time. Numerous other aspects are described.
