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: Systems and methods for communication using hybrid signals are disclosed. In one aspect an apparatus for communication includes a processing system configured to encode a first set of information in a plurality of symbols and to encode a second set of information according to a spacing among the symbols. The apparatus may further comprise a transmitter configured to transmit to a device the symbols with the spacing among the symbols. In another aspect, an apparatus for communication includes a processing system configured to decode a first set of information from a plurality of symbols encoded with the first set of information or a second set of information from a spacing among the symbols by determining the spacing among the symbols. The apparatus may further comprise a receiver configured to receive the symbols via a wireless communication.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, an apparatus may be configured to determine whether to switch to an active mode, a power save mode, or a TWT power save mode. During the TWT power save mode, the apparatus may enter an awake state during TWT service periods and may enter a doze state outside of the TWT service periods. The apparatus may transmit a message to a second wireless device based on the determination.

Abstract: Systems, methods, and devices for concurrently allowing station-to-station transmissions and access point-to-station transmissions are described herein. In some aspects, a method comprises transmitting, to an access point, a request for an available channel frequency. The method further comprises receiving a coordination message from the access point. The coordination message may indicate that a first frequency channel is allocated for transmissions between a first device and a second device and that a second frequency channel is allocated for transmissions between a third device and a fourth device. The method further comprises transmitting a first data packet to the fourth device using the second frequency channel concurrently with a transmission of a second data packet between the first device and the second device using the first frequency channel.
