摘要： A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. Short training field (STF) sequences are designed using a base binary sequence. In some examples, the base binary sequence is specified as [−1, −1 −1 +1 +1 +1 −1, +1, +1 +1 −1 +1 +1 −1, +1]. One STF includes the base binary sequence mapped. Another STF includes the base binary sequence followed by 0 followed by a phased rotated version of the base binary sequence. Another STF includes the base binary sequence followed by 0 followed by an inverted version of the base binary sequence.

摘要： A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV supports first communications with another WDEV to determine an agreed-upon orthogonal frequency division multiple access (OFDMA) resource unit (RU) and agreed-upon OFDMA sub-carriers to be used by the other WDEV to provide predetermined response(s). The WDEV then transmits a question to the WDEV and processes the plurality of agreed-upon OFDMA sub-carriers within the OFDMA RU to determine whether energy therein indicates a response of the one or more predetermined responses to the question being received from the other WDEV in accordance with second communications.

摘要： A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications. The device then generates and transmits acknowledgement(s) (ACK(s)) indicates successful receipt of any responses from the authorized device(s).

摘要： A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV receives a null data packet (NDP) announcement frame that specifies a sub-carrier (SC) or tone grouping factor, a communication channel bandwidth, and other WDEV(s) to respond with beamforming feedback. The WDEV process the NDP announcement frame to determine it is to respond, and if so, then receives a NDP sounding frame that includes long training fields (LTFs) and pilots at predetermined locations and generates beamforming feedback of communication channel estimates at SCs as determined based on a sub-carrier roster look up table (LUT).

摘要： A wireless communication device (alternatively, device) includes a processing circuitry configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. A device generates and transmits a request to send (RTS) to group (RTG) frame to other devices. In response to the RTG frame, the device receives clear to send (CTS)(s) from one or more of the other devices and generates and transmits an orthogonal frequency division multiple access (OFDMA) data frame to those one or more of the other devices based thereon. The RTG frame can include different RTSs transmitted via different channels, sub-channels, sub-carriers, etc. to the different other devices.

摘要： A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV selects a resource unit (RU) from an orthogonal frequency division multiple access (OFDMA) sub-carrier plan for use in supporting communications with another WDEV. The WDEV transmits a signal to the other WDEV that includes information that specifies the RU that is selected from the OFDMA sub-carrier plan and then supports communications with the other WDEV using the RU that is selected from the OFDMA sub-carrier plan. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs and null sub-carriers.

摘要： Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.) for the first and second wireless communication devices, synchronization to a common clock (e.g., using timing synchronization function (TSF)).

摘要： Methods, systems, and apparatuses are described for providing device(s) with additional processing time to process a packet received wirelessly while still meeting the legacy SIFS time constraint. The additional processing time may be achieved by adding, by a device transmitting the packet, padding and/or a packet extension to the last symbol of the packet. The additional processing time provided to the device(s) advantageously reduces the amount of extra hardware that would normally be added to meet the SIFS time constraint. The amount of padding and/or packet extension to be added to the last symbol is balanced to minimize the complexity of the device(s) against the reduction in system efficiency incurred by the device(s).

摘要： A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV monitors for ongoing transmission(s) on a wireless communication medium before transmitting a signal to another WDEV via the wireless communication medium. The WDEV uses different threshold levels (and/or variable threshold level functions) based on whether a detected ongoing transmission is associated with a first or second wireless communication network to determine when to make a concurrent transmission. For example, different WDEVs are associated with different wireless communication networks, and the WDEV uses different considerations to determine when to make transmissions in different situations.

摘要： A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. The device is configured to generate OFDM/A packets having certain characteristics based on different packet formats. For example, a first OFDM/A packet has first characteristic(s) based on a first packet format, a second OFDM/A packet has second characteristic(s) based on a second packet format, and so on. A receiver device is configured to process such OFDM/A packets to determine characteristic(s) thereof to determine, identify, classify, etc. their respective packet formats so that the OFDM/A packets can be properly and appropriately processed based on their particular packet formats.
