Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling aggregated control information in a wireless communication network. A frame format may include an aggregated control (A-Control) field. In one aspect, the A-Control field may be variable-length to support signaling multiple types of control information. In some implementations, an access point may manage multiple links (multi-link). The A-Control field may be structured to include multi-link control information. This disclosure includes multiple options for extending an A-Control field. Furthermore, a receiving device may acknowledge the A-Control field using various techniques disclosed herein.

Abstract: Systems and methods are disclosed for a wireless device to transmit or receive a channel busy time (CBT) to or from other devices in a wireless network. For transmitting, the wireless device may determine a CBT during which a wireless channel is to be occupied, generate a universal reservation signal (URS) indicating the CBT, and transmit on the wireless channel the URS to at least one other wireless device. For receiving, the wireless device may receive on a wireless channel a URS from a second wireless device, the URS configured to indicate the CBT. The wireless device may also refrain from attempting to transmit on the wireless channel during the CBT.

Abstract: Certain aspects of the present disclosure relate to a method for enhanced multi-user multiple input multiple output (MU-MIMO) wireless communications. The proposed method may reduce and/or eliminate stringent frequency and time synchronization requirements for stations (STAs) to participate in a downlink MU-MIMO transaction by utilizing deterministic scheduling.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to protecting control frames with power-related subfields. One example apparatus for wireless communications generally includes a processing system configured to generate a control frame comprising one or more power-related subfields and an integrity check value calculated based, at least in part, on the one or more power-related subfields and a transmitter configured to transmit the control frame. In aspects, a power management (PM) subfield, an end-of-service-period (EOSP) subfield, a more data (MD) subfield, or a traffic identifier (TID) subfield can be added to a group of additional authentication data (AAD) and the integrity check value is calculated based on the group of AAD.

Abstract: Methods and systems for coordinating simultaneous transmission by two or more access points over a single channel of a wireless medium are disclosed. In one aspect, a method includes determining, by an access point, a plurality of opportunities for initiating synchronized transmissions over the channel, and initiating by the first wireless device, a transmission at an opportunity of the plurality of opportunities.

Abstract: Systems and methods are disclosed for a wireless device to share a wireless medium with other devices. The wireless device may perform a first backoff using a first backoff value, transmit on the wireless medium after performing the first backoff, and use a non-random backoff value to perform a subsequent backoff when the transmission is successful.

Abstract: Apparatuses and methods are disclosed that may allow a wireless device to process an Ethertype data packet encapsulated in a frame based on whether the frame contains an Ethertype Packet Discrimination (EPD) indicator. The wireless device may receive the frame from another wireless device over a wireless network, and may detect a presence of the EPD indicator in the received frame. Then, the wireless device may identify a protocol type of the Ethertype data packet according to an EPD operation based on the presence of the EPD indicator, or may identify the protocol type of the Ethertype data packet according to an LPD operation based on an absence of the EPD indicator.

Abstract: Systems, methods, and devices for configuring connectivity in a wireless network are described herein. In some aspects, a wireless device configured to connect to a first wireless network includes a receiver configured to receive a first dynamic host configuration protocol (DHCP) message from a first network device on the first wireless network. The wireless device further includes a processor configured to determine whether the first DHCP message indicates that the first wireless network does not provide access to a second network. The processor is further configured to determine whether to maintain a connection to the second network accessed using a third wireless network based on the first DHCP message. The leader device further includes a transmitter configured to transmit a second DHCP message to the first network device to connect to the first wireless network. The wireless device is further configured to supply devices on a first wireless network with access to a second network.
