USER EQUIPMENT-SPECIFIC SCHEDULING REQUEST REPETITIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17959018 titled 'USER EQUIPMENT-SPECIFIC SCHEDULING REQUEST REPETITIONS
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The focus is on a high reliability and low latency communications system, specifically ultra-reliable low latency communications (URLLC). The patent introduces a base station and a user equipment (UE) that can communicate in this system.
- The base station signals a UE-specific scheduling request (SR) repetition configuration to the UE.
- The UE uses this configuration to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet.
- The UE repeatedly transmits the SR until a certain number of repetitions or a time period is met, or until an uplink grant is received from the base station.
- The SR repetition configuration includes parameters such as repetition setting, power settings, resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.
Potential Applications
This technology has potential applications in various wireless communication systems, particularly those requiring high reliability and low latency. Some potential applications include:
- Industrial automation: Enables real-time communication between machines and control systems in industrial settings.
- Autonomous vehicles: Facilitates reliable and low-latency communication between autonomous vehicles and infrastructure, improving safety and coordination.
- Remote surgery: Allows for real-time communication between surgeons and robotic systems in remote surgery scenarios.
- Public safety: Enhances communication between emergency responders and command centers, enabling faster and more reliable coordination.
Problems Solved
The patent addresses the following problems in wireless communications:
- Reliability: By utilizing a repetition-based approach for scheduling requests, the system ensures that the base station receives the request even in challenging wireless environments.
- Low latency: The system allows for instantaneous transmission of scheduling requests triggered by new data packets, reducing communication delays.
- Resource optimization: The configuration parameters provided in the SR repetition configuration help optimize the allocation of resources for scheduling requests, improving overall system efficiency.
Benefits
This technology offers several benefits in wireless communications:
- Improved reliability: The repetition-based approach ensures that scheduling requests are reliably received by the base station, even in noisy or congested environments.
- Reduced latency: Instantaneous transmission of scheduling requests minimizes communication delays, enabling real-time or near real-time applications.
- Efficient resource allocation: The configuration parameters in the SR repetition configuration optimize the allocation of resources, maximizing system efficiency and capacity.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.
