Abstract: An aspect of the disclosure provides a wireless frame transmission method. Such a method includes duplicating a preamble in the frequency domain to form at least one duplicate preamble, each preamble having multiple fields. The method further includes puncturing at least one of the preamble fields in the preamble with a first puncturing pattern and puncturing corresponding preamble fields in the at least one duplicate preamble with at least one additional puncturing pattern. The method further includes transmitting a frame including the preamble, the at least one duplicate preamble and a payload. In some embodiments the preamble and the duplicate preambles are each at different frequencies.

Abstract: A method for transmitting a frame includes generating an omni portion of the frame, the omni portion including a non-beamformed long training field and a signal field, the non-beamformed long training field including channel estimation information used to decode the signal field, the non-beamformed long training field configured to be transmitted through one of multiple antennas and multiple streams. The method also includes generating a multi-stream portion of the frame, the multi-stream portion including a data field and a multi-stream long training field, the multi-stream long training field including station-specific decoding information for station-specific data in the data field. The method further includes applying a beamforming indicator to the signal field of the omni portion, and transmitting the frame.

Abstract: A method is described for providing extended wireless coverage. The method includes transmitting, by a station (STA), at least a first frame including one or more short training fields (STFs) and a legacy STF, each of the one or more STFs carrying a sequence of symbols that is orthogonal to a sequence of symbols carried by the legacy STF.

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.
