JOINT SCHEDULING OF SIDELINK AND UU LINK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17761447 titled 'JOINT SCHEDULING OF SIDELINK AND UU LINK

Simplified Explanation

The abstract describes a patent application related to a communication system involving two user equipment (UE) devices. The first UE is able to communicate with a base station through a Uu link and with a second UE through a sidelink. The first UE sends a joint scheduling request and a joint buffer status report (BSR) to the base station for an uplink transmission on the Uu link and a sidelink transmission with the second UE. The joint BSR includes information about the relative latency of both transmissions. The first UE receives a joint transmission grant from the base station, which schedules the uplink transmission on a specific set of resources and the sidelink transmission on another set of resources. The first UE then transmits the uplink transmission on the first set of resources and the sidelink transmission on the second set of resources.

  • The patent application involves a communication system with two UEs, a base station, and a sidelink.
  • The first UE is capable of transmitting data to both the base station and the second UE simultaneously.
  • The first UE sends a joint scheduling request and buffer status report to the base station for both the uplink and sidelink transmissions.
  • The joint buffer status report includes information about the relative latency of both transmissions.
  • The base station grants the first UE permission to transmit on specific sets of resources for both the uplink and sidelink transmissions.
  • The first UE then transmits the uplink data on the allocated resources for the uplink transmission and the sidelink data on the allocated resources for the sidelink transmission.

Potential Applications

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

  • Cellular networks: It can enhance the efficiency and reliability of communication between UEs and base stations.
  • Vehicle-to-vehicle (V2V) communication: It can enable simultaneous communication between vehicles and infrastructure, improving safety and traffic management.
  • Internet of Things (IoT): It can facilitate communication between IoT devices and gateways, enabling seamless connectivity and data exchange.

Problems Solved

The patent application addresses the following problems in communication systems:

  • Simultaneous transmission: It allows the first UE to transmit data to both the base station and the second UE simultaneously, improving overall system capacity and reducing latency.
  • Resource allocation: The joint transmission grant ensures efficient allocation of resources for both the uplink and sidelink transmissions, optimizing system performance.
  • Latency management: The inclusion of relative latency information in the joint buffer status report helps in coordinating and prioritizing the transmission of data between the UEs and the base station.

Benefits

The technology described in the patent application offers several benefits:

  • Improved efficiency: Simultaneous transmission and optimized resource allocation enhance the overall efficiency of the communication system.
  • Reduced latency: The inclusion of relative latency information allows for better management of transmission timing, reducing overall latency.
  • Enhanced reliability: Simultaneous communication between UEs and the base station improves system reliability and ensures uninterrupted data transmission.


Original Abstract Submitted

A first user equipment (UE) is configured to communicate with a base station over a Uu link and communicate with a second UE over a sidelink. The first UE transmits a joint scheduling request and a joint buffer status report (BSR) for an uplink transmission on the Uu link with the base station and a sidelink transmission on the sidelink with the second UE. The joint BSR is associated with a relative latency of the uplink transmission and the sidelink transmission. The first UE receives from the base station, a joint transmission grant scheduling the uplink transmission on a first set of resources and scheduling the sidelink transmission on a second set of resources. The first UE transmits a first transmission on the first set of resources for the uplink transmission and a second transmission on the second set of resources for the sidelink transmission.
