METHOD AND DEVICE FOR PERFORMING GROUPCAST TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18031107 titled 'METHOD AND DEVICE FOR PERFORMING GROUPCAST TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The patent application describes a method and device for performing groupcast transmission in a wireless communication system. Here are the key points:
- The method involves transmitting a synchronization signal block (SSB) through an SSB beam.
- The transmission terminal receives a discovery message from each of multiple terminals in response to the SSB.
- Based on the discovery messages, the transmission terminal determines a groupcast transmission timing for specific terminals.
- The transmission terminal then sends a group transmission/reception timing message to the specific terminals, indicating the groupcast transmission timing.
- Finally, the transmission terminal performs groupcast transmission for the specific terminals using the SSB beam at the designated groupcast transmission timing.
Potential applications of this technology:
- Wireless communication systems that require efficient groupcast transmission.
- Networks where multiple terminals need to receive synchronized transmissions.
- Broadcasting systems that need to transmit data to specific groups of terminals simultaneously.
Problems solved by this technology:
- Efficient groupcast transmission: The method allows for the transmission of data to specific groups of terminals at the same time, improving efficiency.
- Synchronized reception: By determining the groupcast transmission timing based on discovery messages, the method ensures that multiple terminals receive the transmission simultaneously.
Benefits of this technology:
- Improved efficiency: Groupcast transmission reduces the need for individual transmissions to each terminal, saving bandwidth and resources.
- Synchronized reception: The method ensures that multiple terminals receive the transmission at the same time, enabling synchronized actions or interactions.
- Enhanced reliability: By using the SSB beam for groupcast transmission, the method can provide a reliable and robust communication link.
Original Abstract Submitted
Provided are a method by which a transmission terminal performs groupcast transmission in a wireless communication system, and a device. The method transmits a synchronization signal block (SSB) through an SSB beam, receives, from each of a plurality of terminals, a discovery message as a response to the SSB, determines a groupcast transmission timing for specific terminals from among the plurality of terminals on the basis of the discovery message, transmits, to the specific terminals, a group transmission/reception timing message indicating the groupcast transmission timing, and performs groupcast transmission for the specific terminals by using the SSB beam at the groupcast transmission timing.
