Publication number: 20200128568Abstract: Systems and methods for ultra-protected scheduling are disclosed. In some embodiments, a method of operation of a first node includes determining a part of radio resources on which some traffic types can only be scheduled using ultra-protected scheduling messages. The method also includes scheduling a second node to use the part of the radio resources using an ultra-protected scheduling message. In some embodiments, the part of the radio resources is used for Ultra Reliable Communication (URC) and scheduling the second node to use the part of the radio resources for non-URC transmissions. In this way, there may be reduced risk that any node incorrectly transmits in the part of the radio resources and interferes with traffic on the part.Type: ApplicationFiled: October 27, 2017Publication date: April 23, 2020Inventors: Robert Baldemair, Johan Axnäs
