Methods and apparatus for scheduling resources in radio access networks

A method, performed in a radio access network (RAN) associated with a core network, for scheduling resources in the RAN according to a transmission schedule associated with an external network, the method comprising:

• receiving, from the core network, a request to allocate radio resources between the RAN and a user equipment (UE) for communication of a time-sensitive data stream, wherein the time-sensitive data stream is a data stream of a Time-Sensitive Network (TSN) and the request further comprises information related to a transmission schedule associated with the data stream;
• based on the information related to the transmission schedule, determining whether radio resources can be allocated to meet the transmission schedule;
• and
• sending, to the core network, a response indicating whether the radio resources can be allocated to meet the transmission schedule.

A method, performed in a user equipment (UE) in communication with a radio access network (RAN), for scheduling resources in the RAN according to a transmission schedule associated with an external network, the method comprising:

• receiving, from the external network, a transmission schedule associated with a time-sensitive data stream, wherein the time-sensitive data stream is a data stream of a Time-Sensitive Network (TSN);
• sending, to an access management function (AMF) of a fifth-generation (5G) core network associated with the RAN, a request to allocate radio resources for communication of the data stream between the UE and the RAN, wherein the request further comprises information related to the transmission schedule;
• and
• receiving, from the AMF of the 5G core network, a response indicating whether radio resources can be allocated to meet the transmission schedule associated with the data stream.
