Abstract: Apparatuses, systems, and methods for QoS impact mitigation during unavailability of RAN support of network slicing, e.g., in 5G NR systems and beyond. A UE may determine, while connected to a first cell of a network, whether handover instructions include DRB setup instructions on a second cell of the network for a PDU session established towards a first network slice on the first cell. The UE may, upon expiration of a timer initiated in response to the determination and/or confirmation that the second cell does not support network slicing, route, upon determining that there is not a neighboring cell that supports the first network slice and/or that there is not a routing rule for the first network slice that allows routing of traffic to another established DRB, user plane traffic to an eMBB DRB.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing cell search based on battery conditions of a user equipment (UE). For example, some aspects of this disclosure relate to a UE. The UE includes a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to perform a cell search cycle in response to a determination that a connection with the base station has been lost. In response to a determination that UE is in a no-service mode or in a limited-service mode after the cell search cycle, the processor further configures a sleep timer value based at least on one of a charge level of a battery of the UE or a capacity level of the battery. The processor further performs a second cell search cycle after the configured sleep timer value.
