Abstract
An application layer in a device, a service data adaptation protocol (SDAP) layer in the device, and/or a media access control (MAC) layer in the device may determine that wireless communication resources allocated to the device need to be adjusted. The determination may be in response to detecting that a quality of the wireless connection of the device has deteriorated, or it may be based on advance knowledge of information pertaining to an application layer payload in the device. In response to the determination the device may transmit, in a MAC Control Element (MAC CE) to a base station, a request for an adjustment of the allocated wireless communication resources. The adjustment may lead to a temporary boost of resources for a limited period of time or to a persistent update of the allocated wireless communication resources. To allow better scheduling of multiple QoS flows mapped to the same DRB and better selection of data when constructing a MAC Packet Data Unit (PDU), a mapping between QoS flows and LCHs may also be provided to the MAC layer.
