POWER HEADROOM REPORTING FOR SIDELINK COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17914715 titled 'POWER HEADROOM REPORTING FOR SIDELINK COMMUNICATIONS
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on establishing a sidelink communication link between a base station and a second user equipment (UE) via a first UE, which may act as a relay device. The first UE receives control signaling from the base station to configure the transmission of a power headroom report for transmissions over the sidelink communication link. The first UE determines the power headroom, which represents the available transmission power, based on its own transmission power capability. The first UE then transmits the power headroom report to the base station. The base station uses this report to schedule communications with the second UE.
- A relay device (first UE) establishes a sidelink communication link between a base station and a second UE.
- The first UE receives control signaling from the base station to configure the transmission of a power headroom report.
- The first UE determines the power headroom based on its own transmission power capability.
- The first UE transmits the power headroom report to the base station.
- The base station schedules communications with the second UE based on the received power headroom report.
Potential Applications
This technology has potential applications in various wireless communication scenarios, including:
- Internet of Things (IoT) networks where relay devices can extend the coverage and improve connectivity.
- Public safety networks where reliable and efficient communication between base stations and UEs is crucial.
- Industrial automation systems where reliable and low-latency communication is required for control and monitoring.
Problems Solved
This technology addresses several challenges in wireless communications:
- Efficient utilization of resources by allowing relay devices to establish sidelink communication links.
- Optimized scheduling of communications based on the power headroom reports, ensuring reliable and interference-free transmissions.
- Improved coverage and connectivity in scenarios where direct communication between the base station and the second UE is challenging.
Benefits
The use of this technology offers several benefits:
- Enhanced coverage and connectivity by leveraging relay devices to establish sidelink communication links.
- Efficient resource allocation and scheduling based on power headroom reports, leading to improved overall system performance.
- Flexibility in deploying wireless communication networks by enabling relay devices to extend coverage and fill coverage gaps.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A first user equipment (UE), which may be a relay device, may establish a sidelink communication link for communications between a base station and a second UE via the first UE. The first UE may receive control signaling from the base station indicating a configuration for transmitting a power headroom report for transmissions scheduled over the sidelink communication link. The first UE may determine a power headroom associated with transmissions from the first UE to the second UE, which may be based on a transmission power capability of the first UE, and the first UE may transmit a power headroom report to the base station. The base station may schedule communications with the second UE based on the received power headroom report from the first UE.
