Patent number: 11963058Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.Type: GrantFiled: May 10, 2021Date of Patent: April 16, 2024Assignee: Apple Inc.Inventors: Qiming Li, Chunhai Yao, Dawei Zhang, Huaning Niu, Jie Cui, Manasa Raghavan, Xiang Chen, Yang Tang, Yushu Zhang
