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:
Methods, systems, and devices for data rate adaptation to extend the range of wake-up radio transmissions sent to a wake-up radio of a station (STA). Data rate adaptation procedures may be used to select a data rate for wake-up radio transmission based on one or more identified parameters. An access point may execute one or more different types of rate adaptation procedures to select the appropriate data rate. In some examples, the access point may select a data rate of wake-up radio transmissions based on one or more messages failing to be successfully decoded. In some examples, the access point may select a data rate of wake-up radio transmissions based on a distance between the access point and the station. In some examples, the access point may select a data rate of wake-up radio transmission based on information identified during a training procedure.
Abstract:
Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.
Abstract:
Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.
Abstract:
Various aspects of the disclosure relate to communication using a data unit that includes a plurality of segments, where the different segments include information for different users. In some aspects, the data unit may be a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) for Wi-Fi communication. In some aspects, the data unit may include an indication that all of the segments have the same length and/or resource allocation.
Abstract:
Source and sink devices are adapted to facilitate streaming of screen content data. According to one example, a source device can capture video data and graphics data for one or more frames. The video data may be transmitted via a first protocol path and the graphics data may be transmitted via a second protocol path, where the second protocol path is different from the first protocol path. The sink device may receive the video data and graphics data, and may render the video data and graphics data for the one or more frames. Other aspects, embodiments, and features are also included.
