Abstract

Techniques and devices for service-specific tagging of data by an application processor (AP) of a user equipment device (UE). A first indication may be sent from the UE to a baseband processor (BB) of the UE of one or more quality of service preferences for an upcoming data session, and the BB may configure one or more layers of the BB according to the quality of service preferences. The BB may further communicate with a network to establish protocols for the quality of service preferences. The BB may determine one or more network conditions, and may transmit feedback from the BB to the AP related to the determined network conditions. In response, the AP may send a second indication of one or more updated quality of service preferences to the BB based at least in part on the feedback received from the BB.
