US 2021/0243775 A1 · BEARER-LESS ARCHITECTURE FOR A WIRELESS CELLULAR NETWORK

Abstract

An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

Dependent claims

An apparatus for a baseband processor of User Equipment (UE) for a cellular communication network, the apparatus comprising circuitry to:

generate a request to establish a connection with a packet data network (PDN);
process a resource request, associated with the PDN, to determine:
an indication of a Service Data Flow (SDF) associated with the resource request, and
Quality of Service (QoS) information for packets in the SDF;
and
communicate with an evolved NodeB (eNB), via a particular radio bearer established between the UE and the eNB, including:
multiplexing transmission of packets corresponding to a plurality of different SDFs over the particular radio bearer, including scheduling the packets of the plurality of different SDFs based on the QoS information for each of the plurality of different SDFs.
