Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may use wireless local area network (WLAN) signaling fields in a multiple user transmission preamble to communicate with a number of stations greater than a threshold. For example, the AP may determine that the number of stations is greater than the threshold and generate a compression indicator and an indication of the number of stations to include in a first signaling field. The AP may then generate a spatial configuration indicator in a second signaling field based on the number of stations and transmit the first and second signaling fields in a preamble of the multiple user transmission. Upon receiving the preamble, a station may identify the compression indicator and number of stations, and the spatial configuration indicator in the first and second signaling fields, and decode the multiple user transmission using a determined spatial decoding scheme.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for an access point (AP) that may identify a pending communication for a wireless device and transmit a wakeup message comprising a device specific identifier to a wakeup radio of the wireless device. The wakeup message may include a preamble, a signal field, and a data field. In some cases, the wireless device may demodulate the wakeup message using a phase modulated on-off keying (PM-OOK) modulation. After awakening, the wireless device and the AP may exchange data using the primary radio, which may be a wireless local area network (WLAN) transceiver or a wireless wide area network (WWAN) transceiver. The wireless device may receive the wakeup message using the wakeup radio, decode the message to obtain a device specific identifier, and activate a primary radio to communicate with the AP.

Abstract: Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may identify a first indicator identifying a number of multi-user multiple-input/multiple-output (MU-MIMO) stations associated with a first resource unit (RU) in a first content channel of a transmission frame. The transmitter may generate a first common portion of a WLAN signaling field in the first content channel. The first common portion may include the first indicator. The transmitter may identify a second indicator identifying an absence of MU-MIMO stations associated with a second RU in a second content channel of the transmission frame. The transmitter may generate a second common portion of the WLAN signaling field in the second content channel. The second common portion may include the second indicator. The transmitter may transmit the transmission frame including the WLAN signaling field.
