    Abstract: Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.

    Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.

    Abstract: 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.
