Abstract: 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.

Abstract: Methods and apparatuses for supporting outside the context of a basic service set (OCB) concurrent with infrastructure-based communications, including cellular communications or basic service set (BSS) communications, are described. OCB service information is transmitted by an infrastructure unit in an infrastructure-based communication. The OCB service information include a service identifier and channel information for each available OCB service. The infrastructure unit may then communicate with a terminal unit over an OCB communication link, to provide an OCB service to the terminal unit. The OCB service information may be communicated in an OCB operation information element (IE) including a service hash field and an operating class and channel field.

Abstract: Aspects of the present application provide mechanisms for minimizing latency in real time application (RTA) traffic on wireless LANs. A wireless electronic device identifies real time application network packets in the Application layer, gives them a novel MPDU frame type and subtype, and maps them into a high priority access category such as AC_VO. Upon receiving a TXOP, the device preferentially transmits RTA frames before frames mapped to the access category awarded the TXOP. Additional aspects allow for pre-emptive priority transmission of RTA frames.

Abstract: Systems and methods for generating a control signal for automatic wireless network version detection of a transmission. The control signal enables a receiver to detect the wireless network version detection of the transmission, so that the proper wireless network version is used for interpreting signaling information and decoding of the payload of the transmission. In some examples, the control signal is within a preamble of the transmission. The wireless network version can be an IEEE 802.11 version, such as proposed IEEE 802.11be. The control signal is compatible with legacy systems and can indicate the legacy signaling information by way of a Legacy Signal (SIG) (L-SIG) symbol. In some examples, the control signal can indicate the wireless network version by using an identifier symbol which is generated from at least part of, but is not identical to, the L-SIG symbol.

Abstract: Methods and systems that enable payload data to be spread over a number of a plurality of sub-carriers for wireless transmissions between Access Points (AP) and stations (STA) in a WLAN. The AP receives each STA's status information, and controls an amount of spreading of the payload data that can flexibly and variably takes into account the desired amount of peak power consumption, the required data rate, and the channel conditions. Based on these factors, the AP determines a number of sub-carriers for each STA that will be used to carry the spread payload data. Example embodiments can address high power peak consumption, data rate inflexibility and inefficient spectrum communication as found in conventional wireless systems.
