Abstract
For performing a small data transmission triggered in an inactive state of a user equipment (S701, S703), a first transmission method or a second transmission method is selected at least based on a cell of a cellular communication system in which the small data transmission is to be performed by the user equipment (S705). Then the small data transmission is performed using the selected first or second transmission method (S707).
Claims42
A user equipment for use in a cellular communication system, the user equipment comprising:
- at least one processor;
- and
- at least one 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 user equipment at least to perform:
- determining a triggering of a small data transmission in an inactive state of the user equipment;
- selecting a first transmission method or a second transmission method for performing the small data transmission at least based on a cell of the cellular communication system in which the small data transmission is to be performed by the user equipment;
- and
- performing the small data transmission using the selected first or second transmission method.
An apparatus for use in a cellular communication system, the apparatus comprising:
- at least one processor;
- and
- at least one 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 perform:
- providing information of cells or areas of the cellular communication system, wherein the information indicates that, for a small data transmission to be performed by a user equipment in case the user equipment is in an inactive state, a first or second transmission method is to be applied in the cells or areas.
A method for use by a user equipment for use in a cellular communication system, the method comprising:
- determining a triggering of a small data transmission in an inactive state of the user equipment;
- selecting a first transmission method or a second transmission method for performing the small data transmission at least based on a cell of the cellular communication system in which the small data transmission is to be performed by the user equipment;
- and
- performing the small data transmission using the selected first or second transmission method.
A method for use by an apparatus of a cellular communication system, the method comprising:
