COMMUNICATION DEVICE AND COMMUNICATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240284156 titled 'COMMUNICATION DEVICE AND COMMUNICATION METHOD
The present invention involves groupcasting a frame quickly using millimeter wave communication technology. A communication device with a MAC control circuit controls the discovery of communication partner devices and determines the best transmission sector. It also has a wireless circuit for transmitting unicast frames to the partner device using the best sector. The MAC control circuit starts a timer for each discovered partner device and sends a groupcast frame to devices with unfinished timers upon receiving a transmission request from a higher layer.
- Utilizes millimeter wave communication for fast groupcasting
- MAC control circuit manages discovery of partner devices and transmission sectors
- Wireless circuit sends unicast frames using the best transmission sector
- Timer system ensures timely groupcast frame transmission
- Responds to higher layer requests for groupcast frame transmission
Potential Applications: - High-speed data transmission in crowded environments - Efficient communication in IoT networks - Real-time updates in smart city infrastructure
Problems Solved: - Delays in groupcasting frames - Inefficient use of transmission sectors - Difficulty in managing multiple communication partners
Benefits: - Quick and reliable groupcasting - Optimal use of transmission resources - Enhanced network efficiency and performance
Commercial Applications: Title: "Fast Groupcasting Technology for IoT Networks" This technology can be used in smart city applications, industrial IoT systems, and large-scale sensor networks to ensure rapid and efficient data transmission.
Questions about the technology: 1. How does the MAC control circuit optimize transmission sectors for groupcasting? 2. What are the advantages of using millimeter wave communication for fast data transmission?
Original Abstract Submitted
the present invention groupcasts a groupcast frame in a short period of time by using millimeter wave communication. a communication device equipped with a mac control circuit for controlling a procedure for discovering a communication partner device and a procedure for determining the best transmission sector, and also equipped with a wireless circuit for transmitting a unicast frame to the communication partner device by using the best transmission sector, wherein the mac control circuit controls the wireless circuit so as to start a timer for each discovered communication partner device after the procedure for discovering communication partner devices is completed, and transmit a groupcast frame to communication partner devices for which the timer has not finished by using the best transmission sector upon receiving a groupcast frame transmission request from a higher layer before all timers have finished.
