FREQUENCY MULTIPLEXING FOR SIDELINK TRANSMISSIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17997358 titled 'FREQUENCY MULTIPLEXING FOR SIDELINK TRANSMISSIONS

Simplified Explanation

Methods, systems, and devices are described in this patent application to reduce interference caused by power leakage in wireless communications. The innovation focuses on improving sidelink communication between user equipment (UE) and base stations. Here are the key points:

  • The first UE or base station selects communication resources for sidelink communication based on the distance between UEs that have reserved frequency resources in the same time window.
  • A distance parameter is determined between the first UE and other UEs (including a second UE) that have reserved frequency resources within the time window.
  • The distance parameter can represent the physical distance between the first and second UEs or the received power of the second UE's reference signal as received by the first UE.
  • Communication resources are selected based on whether the distance parameter is below a threshold.
  • The first UE then uses the selected resources to communicate the sidelink communication.

Potential Applications

This technology has potential applications in various wireless communication systems, including:

  • Cellular networks: It can be implemented in 4G and 5G networks to improve sidelink communication between UEs and base stations.
  • Internet of Things (IoT): The innovation can enhance communication between IoT devices and gateways, enabling more efficient and reliable data transfer.
  • Vehicle-to-vehicle (V2V) communication: It can be utilized in V2V communication systems to reduce interference and improve the reliability of communication between vehicles.

Problems Solved

The technology addresses the following problems in wireless communications:

  • Interference caused by power leakage: By selecting communication resources based on the distance parameter, the innovation reduces interference caused by power leakage, leading to improved communication quality.
  • Inefficient resource allocation: The system ensures that communication resources are allocated based on the distance between UEs, optimizing resource utilization and reducing interference.

Benefits

The use of this technology offers several benefits:

  • Improved communication quality: By reducing interference, the technology enhances the reliability and performance of sidelink communication.
  • Efficient resource allocation: The system optimizes resource allocation based on the distance parameter, leading to better utilization of available resources.
  • Enhanced wireless connectivity: The innovation improves the overall wireless connectivity experience for users by minimizing interference and maximizing communication efficiency.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described to reduce interference caused by power leakage. A first user equipment (UE) or a base station may select communication resources for a sidelink communication based on a distance between UEs reserving frequency resources in a same time window. The first UE or the base station may determine a distance parameter between the first UE and one or more other UEs (e.g., including a second UE) reserving frequency resources within the time window. The distance parameter may represent a physical distance between the first and second UEs or a reference signal received power of the second UE as received by the first UE. The first UE or the base station may select communication resources based on whether the distance parameter is below a threshold, and the first UE may communicate the sidelink communication using the selected resources.
