METHOD AND APPARATUS FOR INDICATING CONTROL INFORMATION IN A WIRELESS FRAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18221631 titled 'METHOD AND APPARATUS FOR INDICATING CONTROL INFORMATION IN A WIRELESS FRAME
Simplified Explanation
The patent application describes a method, apparatus, and system for transmitting control information in a header of a physical protocol data unit (PPDU) in wireless LAN communications. The method involves overloading at least one bit of a Scrambler Initialization Field in the PPDU header to convey control information and initialize the scrambler shift register. This allows the same header bits to be used for both purposes.
- The method, apparatus, and system transmit control information in a header of a PPDU.
- The Scrambler Initialization Field in the PPDU header is overloaded to convey control information and initialize the scrambler shift register.
- The same header bits are used for both conveying control information and initializing the scrambler shift register.
- Control information can include primary channel, channel width, or MIMO configuration for further communication.
Potential applications of this technology:
- Wireless LAN communications
- IEEE 802.11 compliant PPDU transmissions
Problems solved by this technology:
- Efficient transmission of control information in wireless LAN communications
- Optimization of header space in PPDU transmissions
Benefits of this technology:
- Improved efficiency in transmitting control information
- More effective utilization of header space in PPDU transmissions
Original Abstract Submitted
A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.
