Abstract
There is provided a communication device that includes circuitry for supporting extended reality (XR) services. The communication device obtains information related to XR traffic periods from a core network and uses this to adjust power-saving settings. When a delay between the reception time and the display time of video data at a terminal device exceeds a certain threshold, the communication device modifies scheduling parameters for data transmission. The communication device adjusts the configured grant configuration and optimizes the terminal's reception timing by configuring discontinuous reception (DRX) settings based on control channel monitoring requirements and transmission periodicity.
Claims6
A communication device, comprising:
- circuitry configured to:
- acquire extended reality (XR) traffic period information from a core network, wherein
- the XR traffic period information is indicated by information related to a traffic, and
- the XR traffic period information is included in a Policy and Charging Control (PCC) Rule;
- transmit a Protocol Data Unit (PDU) session establish request for an XR service, wherein
- the PCC Rule is provided in association with a Session Management (SM) Policy Association during a PDU session establishment procedure that corresponds to the PDU session establishment request, and
- the XR traffic period information is used to configure a discontinuous reception (DRX);
- and
- set a plurality of transmission occasions within a single period of a Configured Grant (CG) configuration.
