METHOD FOR TRANSMITTING PHYSICAL LAYER PROTOCOL DATA UNIT AND COMMUNICATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18455889 titled 'METHOD FOR TRANSMITTING PHYSICAL LAYER PROTOCOL DATA UNIT AND COMMUNICATION APPARATUS
Simplified Explanation
The abstract describes an application that allows for the transmission of a PPDU (Physical Protocol Data Unit) and a communication apparatus. The application involves an Access Point (AP) sending a trigger frame to prompt one or more Stations (STA) to transmit an uplink PPDU. The uplink PPDU consists of a data field and LTFs (Long Training Fields). The data field is carried on a distributed RU (Resource Unit), while the LTFs are carried on all subcarriers in a first transmission bandwidth. This first transmission bandwidth is the allocated bandwidth for the distributed RU. Alternatively, the LTFs can be carried on all subcarriers of multiple continuous RUs corresponding to the distributed RU.
- The application enables an AP to trigger STAs to transmit uplink PPDUs.
- The uplink PPDU includes a data field and LTFs.
- The data field is carried on a distributed RU allocated by the AP.
- The LTFs are carried on all subcarriers in a first transmission bandwidth.
- Alternatively, the LTFs can be carried on multiple continuous RUs corresponding to the distributed RU.
Potential Applications
- Wireless communication systems
- Internet of Things (IoT) devices
- Mobile devices
Problems Solved
- Efficient transmission of uplink PPDUs in wireless communication systems
- Improved synchronization and training for uplink transmissions
Benefits
- Enhanced performance and reliability of uplink transmissions
- Optimal utilization of available bandwidth
- Simplified communication protocols and procedures
Original Abstract Submitted
This application provides a method for transmitting a PPDU and a communication apparatus. An AP sends a trigger frame to trigger at least one STA to transmit an uplink PPDU. After receiving the trigger frame, the at least one STA transmits respective uplink PPDUs. The uplink PPDU includes a data field and LTFs. The data field is carried on a distributed RU. The LTFs are carried on all subcarriers in a first transmission bandwidth. The first transmission bandwidth is a bandwidth occupied by a distributed RU that is allocated by the AP to the at least one STA for transmitting the uplink PPDU. Alternatively, the LTFs are carried on all subcarriers of a plurality of continuous RUs corresponding to the distributed RU.
