  • Publication number: 20260247188
    Abstract: Techniques, described herein, include solutions for interruption arrangement for a User Equipment (UE) performing gap-less measurements. Traditionally, a UE configured a time duration, known as a measurement gap, to prepare Radio Frequency (RF) circuitry for performing measurement and to perform measurement. By using spare RF circuitry to perform measurement, a UE may perform ‘gap-less’ measurement without a measurement gap. When preparing for gapless measurement, interruption may occur depending on many factors that may vary depending on the UE and the currently active frequency bands. The UE may use interrupts for the time required to prepare the spare RF circuitry to perform gapless measurement. The UE may communicate to the network a temporal location, and a duration, of the interrupts via various information elements (IEs), so that the network may know when interrupts are allocated.
