Abstract
Disclosed herein are new radio (NR) Data link architecture options including, for example, NR radio bearer models, NR logical channel models, and MAC and HARQ models. Further described are packet flows mapping to data radio bearers (DRBs), and a new flow encapsulation protocol in the user plane. In some embodiments, DRBs with different quality of service (QoS) are pre-established, but not activated. This allows a given user equipment (UE) to use these DRBs for packet data network (PDN) flows without a large overhead. Pre-established DRBs can be an extension to default bearer concept with the decision of pre-establishment of DRBs based on UE capability, subscription profile, operation policy, installed apps, etc.
