    Abstract: A wireless device may utilize enhanced OBSS identification techniques to determine whether an interfering transmission is associated with an OBSS. In an example, a wireless device may receive a WLAN packet that includes a preamble and a data region. The wireless device may analyze the preamble to determine whether the WLAN packet is an OBSS packet. If the wireless device determines there is insufficient information in the preamble to identify the WLAN packet as an OBSS packet, the wireless device may decode a portion of the data region (e.g., a MAC header) to determine if the WLAN packet is an OBSS packet. Prior to declaring a successful decoding of the MAC header, the wireless device may confirm the MAC header has been received reliably. Additionally or alternatively, BSS identifiers may be included in the data region and used to determine if the WLAN packet is associated with an OBSS.

    Abstract: Methods, devices, and computer program products for traffic information signaling in a wireless communications network are disclosed. In one aspect, a method of wireless communication network is disclosed. The method includes selecting, from a variable number of control fields, one or more control fields for inclusion in a frame. The method further includes generating the frame comprising the selected number of control fields, each control field comprising an end of control field, the end of control field storing an indicator indicative of an end of the selected number of control fields or a presence of another control field in the frame. The method further includes transmitting the frame.

    Abstract: Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.

    Abstract: Methods, systems, and devices are described for wireless communications. A network may employ additional contention based parameters to support MU transmissions and to communicate to other devices a duration that protects MU transmission. For example, a first device may transmit a first message to reserve a subband of shared spectrum. The first message may be addressed to multiple devices and may indicate a channel access deferral duration to other devices within transmission range. The non-addressed devices may refrain from accessing the channel for an indicated duration. The addressed devices that receive the first message may respond to the first message with a second message, which may also be used to reserve the channel. The second message may additionally be used to identify those devices that received the first message. The first device may generate a trigger message based on the received second messages.
