US Patent 11350268 End-to-end rate adaptation using RAN assisted rate adaptation

Aspects of the present disclosure provide techniques for end-to-end rate adaptation using radio access network (RAN) assisted rate adaptation. Particularly, when a user equipment (UE) risks operating at rates greater than the guaranteed bit rates (GBR), the UE may rely on rate adaptation mechanisms to indicate when it has exceeded the supported bandwidth such that the UE may reduce its rate accordingly. Specifically, in some examples, a network device (e.g., call session control function (CSCF) and/or policy and charging rules function (PCRF)) may configure endpoints in an end-to-end communication to operate at rates that exceed GBR based on determining that all endpoints support RAN assisted rate adaptation capability. In other examples, the network device may configure maximum bit rates (MBR) that exceed GBR for only the endpoint that supports RAN assisted rate adaptation capability.
