MOBILITY FOR SMALL DATA TRANSMISSION PROCEDURE (18248177)

Main Inventor

Chunli WU

Brief explanation

This patent application is about a method for small data transmission (SDT) between two devices. The first device is in an inactive state and is being served by the second device in a first cell. During the SDT session, the first device checks if a potential cell reselection criterion is met. If it is, the first device sends a signal to the second device indicating its intention to switch cells. This allows the second device to either keep the first device in the inactive state or switch it to the connected state. This ensures that data already transmitted is not lost if a cell reselection occurs before the SDT session is completed.

• The patent application is about a method for small data transmission (SDT) between two devices.
• The first device is in an inactive state and is being served by the second device in a first cell.
• During the SDT session, the first device checks if a potential cell reselection criterion is met.
• If the criterion is met, the first device sends a signal to the second device indicating its intention to switch cells.
• This allows the second device to decide whether to keep the first device in the inactive state or switch it to the connected state.
• The purpose of this method is to prevent data loss if a cell reselection occurs before the SDT session is completed.

Abstract

Embodiments of the present disclosure relate to mobility for small data transmission (SDT) procedure. The first device, which is in an inactive state and served in a first cell of the second device, performs a session of small data transmission between the first device and the second device. The first device determines whether a potential cell reselection criterion is satisfied when the session of small data transmission is ongoing. If a potential cell reselection criterion is satisfied, the first device transmits, to the second device, first information indicating an intention of cell reselection. As such, if the cell reselection happens during SDT procedure, the second device is able to put the first device into either the inactive state or the connected state. Accordingly, already transmitted data is not lost in case cell reselection happens before the session of small data transmission is completed.

• The control information is related to scheduling multicast service traffic to the second device.
• Configuration information is transmitted to the second device to enable it to obtain the control information.
• The control information is then transmitted to the second device on a control channel between the first and second devices, based on the determined transmission scheme.
• This decouples the scheduling mechanism of multicast traffic on the downlink data channel from the transmission mechanism of control information on the downlink control channel.
• The result is a more flexible and dynamic downlink channel configuration and increased efficiency of radio resources.
