Random Access Procedures with Preamble Repetitions - A simplified explanation of the abstract
This abstract first appeared for US patent application 18400837 titled 'Random Access Procedures with Preamble Repetitions
Simplified Explanation: The patent application describes a method for a wireless device to adjust its transmission power and repetition of preamble signals based on the response received from a base station during random access procedures.
Key Features and Innovation:
- Wireless device adjusts transmission power and preamble repetitions based on random access response.
- Different random access procedures may have different quantities of preamble repetitions and reference signals.
- If no response is received after the first set of preamble repetitions, the device increases transmission power for the second set.
- The adjustment is based on factors like the similarity of the first and second sets of repetitions or reference signals.
Potential Applications: This technology can be applied in various wireless communication systems where efficient random access procedures are crucial for establishing connections between devices and base stations.
Problems Solved:
- Ensures reliable communication establishment between wireless devices and base stations.
- Optimizes transmission power and preamble repetitions for better network performance.
Benefits:
- Improved reliability in establishing connections.
- Enhanced network performance and efficiency.
- Adaptability to varying network conditions.
Commercial Applications: Potential commercial applications include telecommunications, IoT devices, and other wireless communication systems where efficient random access procedures are essential for network connectivity and performance optimization.
Questions about Wireless Communication Technology: 1. How does the adjustment of transmission power and preamble repetitions impact the overall network performance? 2. What are the potential challenges in implementing this technology in real-world wireless communication systems?
Frequently Updated Research: Ongoing research in this field focuses on optimizing the algorithm for adjusting transmission power and preamble repetitions based on real-time network conditions to further enhance network performance and reliability.
Original Abstract Submitted
A wireless device may initiate communications with a base station using one or more random access procedures. Different random access procedures may be associated with a different quantity of preamble repetitions and/or different reference signals. Based on a determination that a random access response has not been received in response to a first quantity of preamble repetitions, the wireless device may perform a second quantity of preamble repetitions using a transmission power that is increased based on at least one of: the first quantity of preamble repetitions and the second quantity of preamble repetitions being the same, or a first reference signal (e.g., associated with the first quantity of preamble repetitions) being the same as a second reference signal (e.g., associated with the second quantity of preamble repetitions).
