Abstract: Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.

Abstract: This disclosure provides systems, methods and apparatuses for estimating angular information of a received wireless signal. In some implementations, a receiving device may receive a wireless signal from a transmitting device, and estimate channel conditions, based on a number of sounding sequences, to determine a channel frequency response of the received wireless signal. The receiving device may determine a channel impulse response based an inverse discrete Fourier transfer (DFT) function or a partial inverse DFT function of the channel frequency response, and then select a portion of the channel impulse response. The receiving device may estimate an angle of arrival of the received wireless signal based on the selected portion of the channel impulse response.

Abstract: Methods and apparatuses for providing wireless messages according to various tone plans can include a system configured to generate a message according to a 2048-tone plan having 1960 data tones. The 2048-tone plan includes two identical 1024-tone plans each having 980 data tones. The system can further perform segment parsing to divide data into two data portions, each portion for transmission over one of two 80 MHz bandwidths, according to one of the two identical 1024-tone plans. The system can further perform low density parity check (LDPC) tone mapping separately on each of the two data portions. The system can further provide the message for transmission over a 160 MHz bandwidth including the two 80 MHz bandwidths.

Abstract: Methods, systems, and devices are described for signaling soft time division multiplexing (TDM) assignment information in an enhanced distributed channel access (EDCA) operation. The soft TDM assignment may be sent to one or more nodes of a group of nodes to communicate with indicated priority access parameters during at least one of a plurality of time slots. The soft TDM assignment may also convey one or more backoff operation rules to at least one of the one or more nodes. Further, primary and secondary non-concurrent nodes may be identified and a signal sent to the secondary node for it to communicate, at a different priority than the primary node, during at least one of a plurality of non-concurrent time slots the primary node is communicating during.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a wireless device. The wireless device determines a first subset of resource units (RUs) of a set of RUs that extends across a bandwidth of a channel in a transmission time period, the first subset of RUs including less RUs than the set of RUs, each RU of the set of RUs including at least 26 tones. The wireless device communicates at least one of data or control information in the first subset of the RUs.

Abstract: Systems, methods, and devices for transmitting data are described herein. In some aspects, a method comprises generating a first message. The first message may comprise an allocation of a first station to a first frequency channel and a second station to a second frequency channel. The method further comprises transmitting the first message over the first frequency channel and the second frequency channel. The method further comprises transmitting, after transmission of the first message, a second message to the first station using the first frequency channel. The method further comprises transmitting, after transmission of the first message, a third message to the second station using the second frequency channel.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device, such as a device in a wireless local area network, may use a radio frame structure that includes a high efficiency (HE) signal field and an HE data field for communications, for example, over shared radio frequency spectrum. One or more bits or symbols within the HE signal field may be adjusted to avoid a high peak-to-average power ratio (PAPR). In some cases, the adjustment may be to a signal A (SIG-A) or signal B (SIG-B) field. In some examples, a random bit sequence may be used for padding in a signal field. In other examples, bits may be reversed or scrambled. In yet other examples, bits may be modulated and a phase rotation may be applied to the corresponding signal.
