Abstract: One aspect includes a method of establishing, via a first access point, a distributed MIMO joint transmission opportunity with one or more second access points to one or more stations. The method comprises generating, via a processor, a first message for transmission to the stations and the second access points. The first message indicates a null data packet transmission and the stations configured to receive a stream during the joint transmission opportunity. The method also comprises transmitting the first message to the second access points and the stations. The method further comprises generating, via the processor, a reference phase signal for transmission to the second access points.

Abstract: Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A receiver may receive, at a first station, a transmission frame that includes a WLAN signaling field decodable by a plurality of stations. The receiver may identify, in a station-specific portion of the WLAN signaling field, an order for a plurality of station-specific information blocks associated with the plurality of stations. The receiver may determine a number of spatial streams allocated to the first station based at least in part on the identified order for the plurality of station-specific information blocks.

Abstract: Methods and apparatuses are disclosed for communicating over a wireless communication network. One such apparatus may include a memory and a processor configured to identify a transmission mode for a transmission of a signal; select a tone plan for transmission of the signal within a 320 MHz total channel bandwidth or a 240 MHz total channel bandwidth, where the tone plan includes a 256 point tone plan, 512 point tone plan, 1024 point tone plane, 2048 point tone plan, 4096 point tone plan, and where the tone plan is selected based on the transmission mode; generate the signal according to the tone plan; and transmit the signal over the 320 MHz total channel bandwidth or over the 240 MHz total channel bandwidth. The selected tone plan may include one or more duplicates of an IEEE 802.11ax 80 MHz (HE80) tone plan which may include one or more null space 26 tone resource units.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for establishing communications with one or more devices. In one aspect, a first device generates a wake-up radio (WUR) frame, the WUR frame including a media access control (MAC) header and a frame check sequence (FCS) having a cyclic redundancy check (CRC) or a message integrity check (MIC). The first device may determine the FCS based, at least in part, on the MAC header and basic service set identifier (BSSID) information associated with the first device. The first device may output the WUR frame for transmission to one or more devices. A second device may receive the WUR frame from the first device and determine whether the WUR frame is directed to the second device based, at least in part, on comparing the FCS of the WUR frame with a calculated FCS.

Abstract: Systems and methods are disclosed that may provide for selective multi-user uplink (UL) of data for wireless devices. For example, a first wireless device may request permission to initiate a UL transmission to a second wireless device. The first wireless device may then receive, from the second wireless device, permission to initiate the UL transmission according to a multi-user (MU) UL protocol, determine a threshold duration for the UL transmission, and transmit UL data to the second wireless device according to the MU UL protocol and the threshold duration.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiplexing clients of different generations in trigger-based transmissions, including trigger-based transmissions in extremely-high throughput (EHT) Wi-Fi systems. An access point (AP) may generate a trigger frame compatible with two types of stations (STAs), such as EHT STAs and legacy (or high efficiency (HE)) STAs. The AP may transmit the trigger frame to a group of STAs, where legacy STAs may process the trigger frame a legacy trigger frame. EHT STAs may process the trigger frame to determine resource unit (RU) allocations for uplink transmissions in a bandwidth greater than a legacy bandwidth. An EHT STA may determine the resources in the larger bandwidth based on an EHT RU allocation table, a legacy RU allocation table and an additional bit in the trigger frame, or an ordering of RU allocations in the trigger frame.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for techniques for an access point (AP) in a basic service set (BSS) to advertise or indicate 320 MHz bandwidth operation and frequency segment composition in the 320 MHz bandwidth to a station (STA) in a Wireless Local Area Network (WLAN). Also, a WLAN device may advertise or indicate its 320 MHz bandwidth support capability to other WLAN devices in the WLAN.

Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may configure a preamble for a wireless transmission to include information indicative of a corresponding extremely high throughput (EHT) packet. In some cases, the preamble may be configured to include a signaling field indicative of the EHT packet. In some cases, symbols or bits of the preamble may be configured to indicate the EHT packet. In yet other cases, a field of the packet may be masked to indicate the EHT packet. A wireless station (STA) may receive the configured preamble, and based on the preamble, may receive (e.g., decode) the EHT packet.

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.
