CONNECTED MODE DISCONTINUOUS RECEPTION SETTINGS FOR PERIODIC TRAFFIC WITH JITTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 17942990 titled 'CONNECTED MODE DISCONTINUOUS RECEPTION SETTINGS FOR PERIODIC TRAFFIC WITH JITTER

Simplified Explanation

In a patent application, methods, systems, and devices for wireless communications are disclosed. A network entity can adjust connected mode discontinuous reception (CDRX) configuration parameters for a user equipment (UE) to account for jitter in communications based on estimated downlink traffic arrival times.

  • The network entity estimates a traffic arrival offset for a downlink traffic burst by considering traffic periodicity, estimated arrival time of packets, and jitter parameters representing uncertainty in arrival time.
  • A CDRX offset value is selected based on the estimated traffic arrival offset to optimize communication with the UE.
  • The network entity transmits a message to the UE, such as an extended reality (XR) device, indicating the CDRX offset value as part of a CDRX configuration.

Potential Applications

  • Improved wireless communication performance in environments with high jitter.
  • Enhanced user experience for applications requiring low latency, such as virtual reality or augmented reality.

Problems Solved

  • Mitigating the impact of jitter on wireless communication reliability.
  • Optimizing CDRX configuration for efficient data transmission in varying network conditions.

Benefits

  • Increased stability and reliability of wireless communications.
  • Enhanced performance for real-time applications.
  • Improved overall user experience with wireless devices.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A network entity may account for jitter in communications with a user equipment (UE) by adjusting connected mode discontinuous reception (CDRX) configuration parameters for the UE based on estimated downlink traffic arrival times. For a downlink traffic burst, the network entity may estimate a traffic arrival offset based on determining a traffic periodicity, an estimated arrival time associated with one or more packets of a traffic burst, and at least one jitter parameter. The jitter parameter may represent an uncertainty in the arrival time of the traffic burst. The network entity may select a CDRX offset value based on the estimated traffic arrival offset. The network entity may transmit (e.g., to a UE, such as an extended reality (XR) device) a message indicating the CDRX offset value, for example, as part of a CDRX configuration.
