OVER THE AIR DPD FOR CV2X GROUPCAST AND UNICAST - A simplified explanation of the abstract

This abstract first appeared for US patent application 17457886 titled 'OVER THE AIR DPD FOR CV2X GROUPCAST AND UNICAST

Simplified Explanation

The patent application describes a method for training and optimizing digital pre-distortion (DPD) in wireless communication systems.

  • The first UE (User Equipment) transmits pilot signals to a second subset of one or more second UEs.
  • The first UE receives feedback messages from a third subset of the second UEs, which are based on the pilot signals.
  • Each second UE in the third subset corresponds to one feedback message.
  • The second UE calculates DPD parameters based on the feedback messages.
  • The second UE then transmits a signal using the calculated DPD parameters.

Potential applications of this technology:

  • Wireless communication systems, such as cellular networks, where DPD is used to improve signal quality and reduce interference.
  • Internet of Things (IoT) devices that rely on wireless communication, as DPD optimization can enhance their performance.

Problems solved by this technology:

  • DPD training is essential for optimizing signal quality in wireless communication systems.
  • The proposed method allows for efficient training by using pilot signals and feedback messages.
  • By optimizing DPD parameters, the technology helps to mitigate distortion and interference in wireless transmissions.

Benefits of this technology:

  • Improved signal quality and reduced interference in wireless communication systems.
  • Enhanced performance and reliability of IoT devices.
  • Efficient and effective DPD training, leading to better overall system performance.


Original Abstract Submitted

A first UE may transmit, to a second subset of one or more second UEs, one or more pilot signals associated with DPD training. The first UE may receive, from a third subset of the one or more second UEs, one or more feedback messages associated with DPD training. The one or more feedback messages may be based on the one or more pilot signals. Each second UE in the third subset of the one or more second UEs may correspond to one of the one or more feedback messages. The second UE may calculate one or more DPD parameters based on the one or more feedback messages. The second UE may transmit a first signal based on the calculated one or more DPD parameters.
