Patent number: 11877335Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.Type: GrantFiled: September 30, 2022Date of Patent: January 16, 2024Assignee: QUALCOMM IncorporatedInventors: Yuanbo Wang, Yue Hong, Arvind Vardarajan Santhanam, Thawatt Gopal, Xiaoning Lu, Defang Chen, Viswanath Sankaran, Xiao Cheng, Christopher James Pais, Harsimransingh Narindersingh Bindra, Parth AshwinKumar Pandya, Billy Andika
