Abstract
Method, systems and devices for small data transmissions can occur with user equipment even when the user equipment is in an inactive state. Small data transmissions while in an inactive state can save power and reduce signaling overhead. The small data transmissions may be prepared with small data transmission parameters. A small data transmission indication is included in a reply to user equipment that requests small data transmission communication.
Claims10
A method for wireless communication, comprising:
- receiving, from a user equipment device, a request for a small data transmission, the user equipment device being in an inactive state;
- sending, to the user equipment device, a small data transmission indication in response to the request for the small data transmission, wherein the small data transmission indication comprises a downlink control information (DCI);
- processing the small data transmission;
- and
- configuring small data transmission parameters, via RRCRelease with SuspendConfig, which configure small data transmission resources, wherein the small data transmission resources are released based on the small data transmission parameters upon entry of an idle state for the user equipment device.

A method for wireless communication performed by a user equipment device, comprising:
- sending, while in an inactive state, a request for a small data transmission;
- in response to receiving a small data transmission indication in response to the request for the small data transmission, processing the small data transmission, wherein the small data transmission indication comprises a downlink control information (DCI);
- in response to not receiving the small data transmission indication, resending the request for the small data transmission;
- and
- releasing small data transmission resources based on small data transmission parameters upon entry of an idle state, wherein the small data transmission resources are configured by the small data transmission parameters via RRCRelease with SuspendConfig.

A wireless communication apparatus, comprising:
- a memory operable to store computer-readable instructions;
- and
- a processor circuitry operable to read the computer-readable instructions, the processor circuitry when executing the computer-readable instructions is configured to:
- receive, from a user equipment device, a request for a small data transmission, the user equipment device being in an inactive state;
- send, to the user equipment device, a small data transmission indication in response to the request for the small data transmission, wherein the small data transmission indication comprises a downlink control information (DCI);
- process the small data transmission;
- and
- configure small data transmission parameters, via RRCRelease with SuspendConfig, which configure small data transmission resources, wherein the small data transmission resources are released based on the small data transmission parameters upon entry of an idle state for the user equipment device.
