TECHNIQUES FOR LARGE ROUND TRIP TIMES IN RANDOM ACCESS CHANNEL PROCEDURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17455003 titled 'TECHNIQUES FOR LARGE ROUND TRIP TIMES IN RANDOM ACCESS CHANNEL PROCEDURES
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It focuses on the random access channel procedure between two wireless devices.
- The first wireless device receives a first message from the second wireless device, which includes a preamble and a set of sequences.
- The first wireless device transmits a second message indicating a timing parameter for future communications.
- The first wireless device also sends a third message to the second wireless device indicating another timing parameter.
- The second wireless device may receive control signaling from the first wireless device, specifying a timing offset for the first message.
- In response to the control signaling, the second wireless device transmits the first message using the specified timing offset.
Potential Applications
- Wireless communication systems
- Mobile networks
- Internet of Things (IoT) devices
- Smart home automation
Problems Solved
- Efficient random access channel procedure between wireless devices
- Accurate timing synchronization for subsequent communications
- Minimizing interference and collisions in wireless networks
Benefits
- Improved reliability and efficiency in wireless communications
- Enhanced synchronization between devices
- Reduced interference and improved network performance
- Facilitates seamless integration of IoT devices into existing networks
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A first wireless device may receive, from a second wireless device, a first message of a random access channel procedure. The first message may include a preamble having a cyclic prefix and a set of sequences. The first wireless device may transmit a second message of the random access channel procedure indicating a first timing parameter for subsequent communications between the devices. The first wireless device may transmit a third message to the second wireless device that indicates a second timing parameter. In some cases, the second wireless device may receive control signaling from the first wireless device indicating a timing offset for the first message of the random access channel procedure. The second wireless device may transmit the first message using the timing offset in response to receiving the control signaling.
