    Abstract: A ranging operation between a first wireless device and a second wireless may be performed by: sending, to the second wireless device, a data frame including a request for the second wireless device to report its actual SIFS duration to the first wireless device; determining a time of departure (TOD) of the data frame; receiving, from the second wireless device, a response frame including SIFS information indicative of the actual SIFS duration of the second wireless device; determining a time of arrival (TOA) of the response frame; and determining a round trip time (RTT) of the data frame and the response frame using the TOD of the data frame, the TOA of the response frame, and the actual SIFS duration of the second wireless device.

    Abstract: A wireless transmitter can include a plurality of bandwidth modules, each bandwidth module processing data based on a predetermined frequency band. In one embodiment, such a wireless transmitter can include encoding components for receiving transmit data and generating encoded data. A multiple-input multiple-output (MIMO) stream parser can receive the encoded data and generate a plurality of MIMO streams. A first module parser coupled to a first MIMO stream can generate a first plurality of partial MIMO streams. A first bandwidth module can include a first interleaver that interleaves bits of the first partial MIMO stream and generates first interleaved data. A second bandwidth module can include a second interleaver that interleaves bits of the second partial MIMO stream and generates second interleaved data. A first inverse fast Fourier transform (IFFT) unit can combine and process the first and second interleaved data and generate a first transmission MIMO stream.

    Abstract: The present disclosure provides techniques for preamble puncturing in wireless local area networks (WLANs). In one implementation, an access point (AP) can identify, within a channel width, one or more bandwidth regions associated with incumbent technologies. The AP can broadcast or advertise, to a basic service set (BSS) initiated or started by the AP, a preamble puncture pattern in one or more management frames, the preamble puncture pattern being based on the bandwidth regions associated with incumbent technologies. In another implementation, an AP can identify a single user (SU) preamble puncture transmission, and can signal in a common portion of a SIG-B field of a multi-user (MU) PPDU format that a resource unit (RU) size is assigned to a same user to indicate the SU preamble puncture transmission. Although these techniques may be used in any frequency band, typical frequency bands may include, but are not limited to, a 2.4 GHz band, a 5 GHz band, and/or a 6 GHz band.

    Abstract: Methods and apparatuses can be disclosed for communicating over a wireless communication network. One communication device includes a processor configured to allocate, or receive allocation of, at least a portion of a first sub-band of a channel and at least a portion of a second sub-band of the channel for use by the communication device. The communication device further includes a plurality of encoders configured to independently encode first and second data for wireless transmission over the first and second sub-bands, respectively. The communication device further includes a transmitter configured to transmit the independently encoded first and second data over the first and second sub-bands, respectively.
