ADAPTATION OF POWER CONTROL BASED ON NON-LINEAR INTERFERENCE ANALYSIS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17549716 titled 'ADAPTATION OF POWER CONTROL BASED ON NON-LINEAR INTERFERENCE ANALYSIS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The invention involves a base station receiving an uplink transmission from a user equipment (UE) over a wireless channel and measuring the post-digital post-distortion (post-DPOD) signal-to-noise ratio (SNR) of the transmission. Based on this measurement and a change in the post-DPOD noise level, the base station generates a power output back-off indication for the UE. This indication is then transmitted along with a downlink transmission to the UE. In response, the base station receives another uplink transmission from the UE, which may be influenced by the power output back-off indication and/or a signal quality metric of the downlink transmission.

  • The base station measures the post-DPOD SNR of an uplink transmission from a UE.
  • Based on the post-DPOD SNR and the change in post-DPOD noise level, the base station generates a power output back-off indication for the UE.
  • The power output back-off indication and a downlink transmission are transmitted to the UE.
  • The UE may adjust its uplink transmission based on the power output back-off indication and/or the signal quality metric of the downlink transmission.

Potential Applications

  • This technology can be applied in wireless communication systems, such as cellular networks, to improve the overall performance and reliability of uplink transmissions from user equipment.
  • It can be used in various industries that rely on wireless communication, including telecommunications, IoT, and mobile computing.

Problems Solved

  • The invention addresses the challenge of optimizing uplink transmissions in wireless communication systems by considering the post-DPOD SNR and the change in post-DPOD noise level.
  • It solves the problem of efficiently managing power output levels for user equipment based on the quality of the uplink transmission and the noise characteristics of the wireless channel.

Benefits

  • By generating a power output back-off indication based on the post-DPOD SNR and the change in post-DPOD noise level, the technology allows for more accurate and efficient power control in uplink transmissions.
  • The ability to adjust the uplink transmission based on the power output back-off indication and/or the signal quality metric of the downlink transmission improves the overall performance and reliability of wireless communication systems.
  • This technology can lead to enhanced user experience, reduced interference, and increased network capacity in wireless communication networks.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A base station may receive an uplink transmission from a user equipment (UE) over a wireless channel and measure a post-digital post-distortion (post-DPOD) signal-to-noise ratio (SNR) of the uplink transmission. The base station may generate a power output back-off indication for the UE according to the post-DPOD SNR and a change in a post-DPOD noise level of the transmission between a non-linear distortion noise component and a thermal noise component. The base station may transmit the power output back-off indication and a downlink transmission to the UE. In response, the base station may receive an uplink transmission from the UE over the wireless channel. The uplink transmission may be based on the power output back-off indication, a signal quality metric of the downlink transmission, or both.
