    Abstract: Methods, apparatuses, and computer readable media for pre-association frame exchange using random access are disclosed. An apparatus of a high-efficiency wireless local-area network (HEW) master station is disclosed. The apparatus includes transceiver circuitry and processing circuitry which may be configured to generate a trigger frame for uplink random access (TF-R), and transmit the TF-R. The transceiver circuitry and processing circuitry may be further configured to receive one or more responses in accordance with orthogonal frequency division multiple-access (OFDMA) to the trigger frame from one or more pre-association stations where the responses comprise pre-association identifiers corresponding to the one or more pre-association stations. Moreover, the transceiver circuitry and processing circuitry may be further configured to generate one or more acknowledgements to the one or more pre-association stations, and transmit the acknowledgements in accordance with OFDMA to the one or more pre-association stations.

    Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for communication in a wireless network are generally described herein. In some embodiments, the HEW AP may transmit a resource allocation message to indicate an allocation of sub-channels to one or more HEW stations for uplink data transmissions. Information included in the resource allocation message may include various indicators related to full or partial allocation of the sub-channels and whether equal allocations are made for each of the HEW stations. A sub-channel mapping block may also be included to indicate how the sub-channels are assigned to the HEW stations. In some cases, the length of the sub-channel mapping block may vary based at least partly on the indicators included in the message.

    Abstract: Methods, apparatuses, and computer-readable media for a wireless communication device for transmitting pilots in a wireless local area network are disclosed. The method on a wireless communication device includes receiving one or more packets in a transmit opportunity (TXOP), wherein the one or more packets indicate a schedule for the wireless communications device to transmit. The method further includes transmitting a first pilot carrier in a lower subcarrier of a frequency allocation, and transmitting a second pilot carrier in a higher subcarrier of the frequency allocation. The first pilot and the second pilot may be transmitted simultaneously or in alternative time periods. The lower subcarrier may be the lower one-third of the frequency allocation, and the higher subcarrier may be the higher one-third of the frequency allocation. The wireless communication device may transmit and receive in accordance with OFDMA and 802.11.

    Abstract: Generally discussed herein are systems and apparatuses that may include UL or DL using Multiple User (MU) Multiple Input Multiple Output (MIMO) or frequency multiplexing. The disclosure also includes techniques of using the systems and apparatuses. According to an example, a technique may include transmitting, using a plurality of spatial streams or sub-channels, a Schedule frame (SCH) to a plurality of Stations (STAs) to schedule an Uplink (UL) transmission, or transmitting, using the plurality of spatial streams or sub-channels, a Block Acknowledge (BA) to the plurality of STAs, in response to receiving a Downlink (DL) transmission from the plurality of STAs.

    Abstract translation: 这里通常讨论的是可以包括使用多用户(MU)多输入多输出(MIMO)或频率复用的UL或DL的系统和装置。 本公开还包括使用系统和设备的技术。 根据示例,技术可以包括使用多个空间流或子信道向多个站(STA)发送调度帧(SCH)以调度上行链路(UL)传输,或者使用 响应于从多个STA接收到下行链路(DL)传输,多个空间流或子信道,到多个STA的块确认(BA)。
