Method, apparatus and computer program for activating a scheduling configuration

An apparatus for a terminal, the apparatus comprising:

• at least one processor;
• and
• at least one memory storing computer program code that, when executed by the at least one processor, cause the apparatus to perform:
• receiving a configuration from a network entity with a plurality of scheduling configurations, wherein each of the plurality of scheduling configurations comprise parameters that are adjustable, wherein the at least one parameter is configured to be adjusted to change at least one of:
• a starting subframe of the resources associated with the selected scheduling configuration, a periodicity of the selected scheduling configuration, and a number of resources associated with the selected scheduling configuration;
• receiving, from the network entity, signalling that activates a selected scheduling configuration of the plurality of scheduling configurations, with adjusted parameters;
• changing the configuration of the selected scheduling configuration using the adjusted parameters;
• providing, to the terminal, a plurality of indication delay budgets, each indication delay budget indicating a maximum validity timer for feedback on an outcome of the selected scheduling configuration, being used by the terminal, according to a scheduling criteria to be provided by the terminal to the network entity;
• determining a missing data frame at the network entity;
• and
• providing a timing offset, to the terminal, to change the starting subframe of a next set of resources associated with the selected scheduling configuration.

A method performed by a network entity, the method comprising:

• classifying received data frames into a plurality of classes based on parameters of the received data frames;
• determining a class from the plurality of classes for a next data frame based on the parameters of the previously received data frames, wherein the determination is performed before the next data frame has arrived;
• determining a scheduling configuration from a plurality of scheduling configurations based on the determined class of the next data frame, wherein each of the plurality of scheduling configurations comprises at least one parameter, wherein the scheduling configuration comprises one of:
• a semi-persistent scheduling configuration, and a configured-grant configuration;
• adjusting the at least one parameter of the selected scheduling configuration based on i) the determined class of the next data frame, and ii) information about previous communications of data frames by the network entity, wherein the at least one parameter is adjusted to change at least one of:
• a starting subframe of the resources associated with the selected scheduling configuration, a periodicity of the selected scheduling configuration, and a number of resources associated with the selected scheduling configuration;
• activating the selected scheduling configuration in the terminal with the at least one adjusted parameter, such that the terminal adjusts the at least one parameter of the selected configuration in the terminal;
• associating each of the plurality of classes with a scheduling configuration of the plurality of scheduling configurations;
• providing, to the terminal, a plurality of indication delay budgets, each indication delay budget indicating a maximum validity timer for feedback on an outcome of the selected scheduling configuration, being used by the terminal, according to a scheduling criteria to be provided by the terminal to the network entity;
• determining a missing data frame at the network entity;
• and
• providing a timing offset, to the terminal, to change the starting subframe of a next set of resources associated with the selected scheduling configuration.
