Abstract
According to an aspect, there is provided a terminal device for performing the following. The terminal device obtains, when the terminal device is in an inactive state while a small data transmission, SDT, procedure is ongoing, information that indicates transmission of a data unit over a radio bearer to the terminal device. The terminal device checks whether or not the radio bearer is configured for the SDT procedure. The terminal device determines whether or not to avoid further processing and/or decoding of the data unit based at least on the checking.
Claims18
A terminal device, comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the terminal device at least to perform:
- obtaining, when the terminal device is in an inactive state while a small data transmission (SDT) procedure is ongoing, information that indicates transmission of a data unit over a radio bearer to the terminal device;
- determining that the radio bearer is not configured for the SDT procedure;
- determining to avoid further processing, decoding, or processing and decoding of the data unit based at least on the determining the radio bearer is not configured for the SDT procedure;
- and
- performing one or more actions for avoiding the further processing, decoding, or processing and decoding of the data unit associated with the radio bearer, the one or more actions comprising discarding the data unit.
A method, comprising:
- obtaining, when a terminal device is in an inactive state while a small data transmission (SDT) procedure is ongoing, information that indicates transmission of a data unit over a radio bearer to the terminal device;
- determining the radio bearer is not configured for the SDT procedure;
- determining to avoid further processing, decoding, or processing and encoding of the data unit based at least on the determining the radio bearer is not configured for the SDT procedure;
- and
- performing one or more actions for avoiding the further processing, decoding, or processing and decoding of the data unit associated with the radio bearer, the one or more actions comprising discarding the data unit.
A network node, comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the network node at least to perform:
- transmitting, to a terminal device when the terminal device is in an inactive state while a small data transmission (SDT) procedure involving the terminal device is ongoing, information that indicates transmission of a data unit over a radio bearer to the terminal device, wherein the information is used by the terminal device to determine that the radio bearer is not configured for the SDT procedure, and to perform one or more actions for avoiding further processing, decoding, or processing and decoding of the data unit associated with the radio bearer, the one or more actions comprising discarding the data unit.
