METHOD FOR TRANSMITTING AND RECEIVING DOWNLINK SIGNAL BETWEEN TERMINAL AND BASE STATION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICE SUPPORTING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18396446 titled 'METHOD FOR TRANSMITTING AND RECEIVING DOWNLINK SIGNAL BETWEEN TERMINAL AND BASE STATION IN WIRELESS COMMUNICATION SYSTEM SUPPORTING UNLICENSED BAND, AND DEVICE SUPPORTING SAME

Simplified Explanation

The present invention provides a method for transmitting and receiving a downlink signal between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting the method. As a specific example, the present invention includes a method for: transmitting and receiving a physical downlink control channel (PDCCH) signal in an unlicensed band so that a base station and a terminal transmit and receive system information associated with a particular synchronization signal/physical broadcast channel (SS/PBCH) block; and, based on the PDCCH signal, transmitting and receiving a PDSCH signal including the system information.

• Transmitting and receiving downlink signals in a wireless communication system supporting an unlicensed band.
• Utilizing a physical downlink control channel (PDCCH) signal to transmit system information associated with a synchronization signal/physical broadcast channel (SS/PBCH) block.
• Transmitting and receiving a PDSCH signal based on the PDCCH signal, including the system information.

Potential Applications

This technology can be applied in various wireless communication systems that support unlicensed bands, such as 5G networks, IoT devices, and smart city infrastructure.

Problems Solved

1. Efficient transmission and reception of downlink signals in unlicensed bands. 2. Seamless communication between terminals and base stations in wireless networks.

Possible Prior Art

One possible prior art could be methods for transmitting and receiving downlink signals in licensed bands in wireless communication systems. However, the specific focus on unlicensed bands and the utilization of PDCCH and PDSCH signals for system information transmission may differentiate this invention from existing technologies.

Unanswered Questions

How does this technology impact the overall efficiency of wireless communication systems?

This technology can potentially improve the efficiency of wireless communication systems by optimizing downlink signal transmission in unlicensed bands, leading to faster and more reliable communication. However, the specific quantitative impact on efficiency metrics such as data throughput or latency is not explicitly addressed in the abstract.

What are the potential challenges or limitations of implementing this method in practical wireless communication systems?

While the abstract outlines the method for transmitting and receiving downlink signals in unlicensed bands, it does not delve into potential challenges or limitations that may arise during implementation. Factors such as interference, regulatory constraints, or compatibility with existing infrastructure could be important considerations for real-world deployment.
