METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING PPDU ON BASIS OF FDD IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18455088 titled 'METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING PPDU ON BASIS OF FDD IN WIRELESS LAN SYSTEM
Simplified Explanation
The patent application describes a method and device for transmitting and receiving a PPDU (Physical Protocol Data Unit) in a wireless LAN system using Frequency Division Duplexing (FDD). The method involves an Access Point (AP) transmitting a trigger frame to two Stations (STAs). The AP then transmits a first downlink (DL) PPDU to the first STA and a second DL PPDU to the second STA based on the trigger frame. The AP also receives a first uplink (UL) PPDU from the second STA based on the trigger frame. The trigger frame contains information about the bandwidth of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel, while the second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted, and the first UL PPDU is received after a preset period following the transmission of the second DL PPDU.
- The method allows for efficient transmission and reception of PPDU in a wireless LAN system using FDD.
- The AP can transmit DL PPDU to multiple STAs simultaneously based on a trigger frame.
- The use of primary and secondary channels allows for better utilization of available bandwidth.
- The method ensures synchronized transmission and reception of DL and UL PPDU.
Potential Applications
- This technology can be applied in various wireless LAN systems, such as Wi-Fi networks, to improve the efficiency of data transmission.
- It can be used in environments where multiple STAs need to receive DL PPDU simultaneously.
Problems Solved
- The method solves the problem of inefficient transmission and reception of PPDU in a wireless LAN system using FDD.
- It addresses the challenge of transmitting DL PPDU to multiple STAs simultaneously.
- It solves the issue of synchronized transmission and reception of DL and UL PPDU.
Benefits
- The method improves the overall efficiency and performance of wireless LAN systems by optimizing the transmission and reception of PPDU.
- It allows for simultaneous transmission of DL PPDU to multiple STAs, reducing latency and improving throughput.
- The use of primary and secondary channels enables better utilization of available bandwidth, enhancing the overall network capacity.
Original Abstract Submitted
A method and a device for transmitting and receiving a PPDU on the basis of an FDD in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP transmits a first downlink (DL) PPDU to the first STA on the basis of the trigger frame. The AP transmits a second DL PPDU to the second STA on the basis of the trigger frame. The AP receives a first uplink (UL) PPDU from the second STA on the basis of the trigger frame. The trigger frame includes bandwidth information of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel. The second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted. The first UL PPDU is received after a preset period after the second DL PPDU is transmitted.
