DISTRIBUTED RESOURCE UNIT TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18486055 titled 'DISTRIBUTED RESOURCE UNIT TRANSMISSION
Simplified Explanation
The patent application describes methods, devices, and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. The focus is on physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission.
- PPDU generation based on legacy tone plans: In some implementations, a PPDU is generated using one or more legacy tone plans. A portion of the PPDU is modulated on a number (M) of tones representing a logical RU (resource unit), and these M tones are further mapped to M noncontiguous subcarrier indices according to a distributed tone plan.
- PPDU generation based on distributed tone plan: In other implementations, a PPDU is generated based on a distributed tone plan. A portion of the PPDU is modulated on a number (M) of tones that coincide with M noncontiguous subcarrier indices in accordance with the distributed tone plan.
Potential applications of this technology:
- Increasing the transmit power of wireless communication devices: This technology allows for increased transmit power on PSD-limited wireless channels, improving the range and reliability of wireless communication.
- Distributed transmission support: The innovation enables distributed transmission in wireless communication devices, allowing for efficient utilization of resources and improved network performance.
Problems solved by this technology:
- Power spectral density limitations: The technology addresses the issue of limited transmit power on wireless channels with power spectral density constraints, overcoming the limitations and improving the overall performance of wireless communication.
- Resource utilization: By supporting distributed transmission, the technology optimizes the utilization of resources, reducing interference and maximizing the capacity of wireless networks.
Benefits of this technology:
- Improved range and reliability: By increasing the transmit power, this technology enhances the range and reliability of wireless communication, enabling better coverage and connectivity.
- Enhanced network performance: The support for distributed transmission improves network performance by efficiently utilizing available resources, reducing interference, and increasing overall capacity.
- Compatibility with legacy systems: The ability to generate PPDU based on legacy tone plans ensures compatibility with existing systems, allowing for seamless integration and adoption of the technology.
Original Abstract Submitted
This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.
