PROCEDURE AND SIGNALING FOR SIDELINK DRX ALIGNMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17526996 titled 'PROCEDURE AND SIGNALING FOR SIDELINK DRX ALIGNMENT

Simplified Explanation

The patent application describes techniques for aligning the discontinuous reception (DRX) configuration between inactive/idle user equipment (UE) over an air interface and a sidelink interface. Here are the key points:

  • The method involves a first UE receiving DRX configuration assistance information from a network over an air interface.
  • The first UE then transmits the DRX configuration assistance information to a second UE via a sidelink interface.
  • The second UE uses the received information to determine its sidelink DRX configuration.
  • The first UE receives the sidelink DRX configuration information from the second UE over the sidelink interface.
  • The first UE then transmits the sidelink DRX configuration information to the network over the air interface.
  • The network can provide modified air interface DRX configuration information to the first UE.

Potential applications of this technology:

  • This technology can be applied in wireless communication systems where UEs need to align their DRX configurations over both air interface and sidelink interface.
  • It can be used in scenarios where UEs are in an inactive or idle state but still need to maintain communication capabilities.

Problems solved by this technology:

  • Inactive or idle UEs may have different DRX configurations over the air interface and sidelink interface, leading to inefficient use of network resources.
  • This technology solves the problem of misalignment between the DRX configurations of UEs, ensuring efficient communication and resource utilization.

Benefits of this technology:

  • By aligning the DRX configurations, this technology improves the overall efficiency of wireless communication systems.
  • It helps in reducing unnecessary power consumption by inactive or idle UEs, leading to improved battery life.
  • The alignment of DRX configurations ensures seamless communication between UEs and the network, enhancing the user experience.


Original Abstract Submitted

Certain aspects of the present disclosure provide techniques for air interface and sidelink discontinuous reception alignment for inactive/idle user equipment. A method performed by a user equipment (UE) includes receiving, from a network at a first user equipment over an air interface, discontinuous reception (DRX) configuration assistance information, and transmitting, from the first user equipment to a second user equipment via a sidelink interface, the DRX configuration assistance information. The method may further include receiving, from the second user equipment at the first user equipment via the sidelink interface, sidelink DRX configuration information, wherein the sidelink DRX configuration information is based on the DRX configuration assistance information, and transmitting, from the first user equipment to the network over the air interface, the sidelink DRX configuration information. The method may include receiving, from the network at the first user equipment, modified air interface DRX configuration information for the first user equipment.
