==Dual Active Protocol Stack Handovers Above 24 GHz - A simplified explanation of the abstract==


*This abstract for appeared for US patent application  number 17438179 Titled 'Dual Active Protocol Stack Handovers Above 24 GHz'

==Simplified Explanation==

This abstract describes a technology that allows a user device (UE) to switch between different communication protocols in a frequency range above 24 GHz. The UE can inform a base station that it is capable of performing this type of handover. The UE then receives a command from a target cell to switch from a source cell to the target cell. During the handover process, the UE continues to maintain a data connection with the source cell. It performs measurements on the target cell and then goes through a physical random access channel procedure. Finally, the UE receives a command from the target cell to release the data connection with the source cell.


==Original Abstract Submitted==

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.
