UPLINK POWER CONTROL FOR CROSS-LINK INTERFERENCE SCENARIOS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17757813 titled 'UPLINK POWER CONTROL FOR CROSS-LINK INTERFERENCE SCENARIOS

Simplified Explanation

Abstract Explanation

The abstract of this patent application describes a wireless communication system where one user equipment (UE) receives information about interference from another UE. Based on this interference information, the first UE determines the power at which it should transmit its signal on the uplink.

  • The first UE receives cross-link interference information from the second UE.
  • The cross-link interference information indicates the strength of interference experienced by the second UE.
  • Based on this interference strength, the first UE determines the power at which it should transmit on the uplink.
  • The first UE then transmits its signal on the uplink using the determined transmit power.

Potential Applications

This technology can be applied in various wireless communication systems and scenarios, including:

  • Cellular networks
  • Wi-Fi networks
  • Internet of Things (IoT) devices
  • Satellite communication systems

Problems Solved

This technology addresses the following problems in wireless communication:

  • Interference between user equipment (UE) in a wireless network can degrade the quality of communication.
  • Transmitting at a higher power than necessary can lead to inefficient use of network resources and increased interference to other UEs.
  • Transmitting at a lower power than necessary can result in poor signal quality and reduced coverage.

Benefits

The use of cross-link interference information to determine uplink transmit power offers several benefits:

  • Improved overall network performance by reducing interference between UEs.
  • Optimal use of network resources by adjusting transmit power based on interference strength.
  • Enhanced signal quality and coverage by ensuring appropriate transmit power levels.
  • Increased efficiency and reliability of wireless communication systems.


Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, cross-link interference information identifying a cross-link interference strength at the second UE; determine an uplink transmit power based at least in part on the cross-link interference strength at the second UE; and transmit, on an uplink, using the determined uplink transmit power. Numerous other aspects are provided.
