Abstract
Resource reservation and/or scheduling may take credit-based shaper algorithm/queue behavior, in time sensitive communication, into account. A base station may schedule resources for transmission of time sensitive networking packets based on the state of the credit based shaper queue. The state of the credit based shaper queue may be determined based on real-time credit-based simper assistant information, in an uplink scenario, or output of a simulator of a real-time credit-based shaper queue, in a downlink scenario, or a combination of real-time credit-based shaper assistant information and simulator output.
Claims1
An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- receive a time sensitive networking packet;
- include the time sensitive networking packet in a credit-based shaper queue;
- transmit, to a first node, the time sensitive networking packet via the credit-based shaper queue;
- transmit, to a second node, a report comprising real-time credit-based shaper assistant information associated with the credit-based shaper queue, wherein the transmitting the report comprises:
- transmitting the report periodically within a predetermined period of time,
- transmitting the report aperiodically, or
- transmitting the report with a predetermined periodicity;
- receive one or more resources scheduled for the transmission of the time sensitive network packet;
- transmit, to the second node, one or more credit-based shaper configuration parameters;
- based on receiving a request to transmit the report, transmitting the report in response to the request;
- based on occurrence of an event, transmitting the report in response to the determined event,
- wherein the real-time credit-based shaper assistant information comprises:
- a total number of packets in the credit-based shaper queue,
- a value of a credit parameter of the credit-based shaper queue, and
- an estimated time to clear the credit-based shaper queue,
- wherein the apparatus further comprises:
- a user equipment, a device-side time sensitive networking translator located at the user equipment, a user plane function, and a network-side time sensitive networking translator located at a user plane function,
- wherein the one or more resources is scheduled for uplink time sensitive communication, and
- wherein the one or more credit-based shaper configuration parameters comprises:
- a traffic class of the credit-based shaper queue,
- a priority of the credit-based shaper queue,
- a rate at which the value of the credit parameter increases while frames in the credit-based shaper queue are not being transmitted, and
- a rate at which frames in the credit-based shaper queue are transmitted.
