ADAPTIVE UPLINK SU-MIMO PRECODING IN WIRELESS CELLULAR SYSTEMS BASED ON RECEPTION QUALITY MEASUREMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17920190 titled 'ADAPTIVE UPLINK SU-MIMO PRECODING IN WIRELESS CELLULAR SYSTEMS BASED ON RECEPTION QUALITY MEASUREMENTS

Simplified Explanation

The patent application describes a network node that is configured to optimize the selection of precoders for uplink transmissions in a wireless communication system. Here is a simplified explanation of the abstract:

  • The network node transmits signaling of uplink grants, indicating a set of precoders for a group of uplink transmissions.
  • It determines reception quality metrics for each of the uplink transmissions.
  • Based on these metrics, it selects a precoder that meets a predefined exploitation selection criterion for uplink transmission.
  • If the selected precoder fails to meet the criterion, a new set of precoders is formed for the next group of uplink transmissions.

Potential applications of this technology:

  • Wireless communication systems, such as cellular networks, where efficient uplink transmission is crucial.
  • Internet of Things (IoT) devices that rely on wireless communication for data transmission.

Problems solved by this technology:

  • Optimizes the selection of precoders for uplink transmissions, improving the overall performance and efficiency of the wireless communication system.
  • Reduces interference and improves signal quality, leading to better data transmission.

Benefits of this technology:

  • Enhanced performance and efficiency of uplink transmissions in wireless communication systems.
  • Improved signal quality and reduced interference, resulting in better data transmission.
  • Increased capacity and throughput of the wireless network.
  • Better utilization of available resources, leading to improved overall network performance.


Original Abstract Submitted

A network node is configured to: cause transmission of signaling of uplink grants indicating a first exploration set of precoders for a first plurality of uplink transmissions where each precoder of the first exploration set of precoders is associated with an uplink transmission of the first plurality of uplink transmissions; determine a first plurality of reception quality metrics associated with the first plurality of uplink transmissions; determine a first precoder of the first exploration set of precoders based on the first plurality of reception quality metrics; select the first precoder of the first exploration set of precoders for uplink transmission based on the first precoder meeting a predefined exploitation selection criterion; and form a second exploration set of precoders to be associated with a second plurality of uplink transmissions based on the first precoder failing to meet the predefined exploitation selection criterion.
