Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol may be based on a hybrid automatic repeat request (HARQ) protocol that supports a delayed acknowledgement for a HARQ retransmission based on receiver processing capability. A first WLAN device may determine that a second WLAN device requires more time to process the HARQ retransmission and may transmit a different communication (interlaced within the HARQ process) to either the second WLAN device or a third WLAN device during the time that the second WLAN device is processing the HARQ retransmission.

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: This disclosure provides methods, devices, and techniques to indicate operations by extremely high throughput (EHT) devices on an operating bandwidth, including devices in a basic service set (BSS) supporting the use of a 320 MHz channel. In some aspects, the supported functionality may include extensions to flexibility and support rules, structures, and signaling using legacy fields, frames, and features. In addition, the supported functionality may include channel sensing and reporting, such as per-channel network allocation vectors (NAVs) for the sub-channels of the operating bandwidth. A device may identify an operating mode for an operating bandwidth and determine a value for a bandwidth query report (BQR) or a target wake time (TWT) element. The device may check multiple NAVs for sub-channels of the operating bandwidth. The operating bandwidth may span concurrent operations on traditional Wi-Fi frequency bands including the 2.4 and 5 GHz bands as well as the 6 GHz band.

Abstract: This disclosure provides methods, devices, and systems for wireless communications. In some systems, an access point (AP) may assign a resource unit (RU) including a non-contiguous set of tones of a channel to a wireless node, such as a station (STA). The non-contiguous set of tones includes at least some tones that are non-contiguous in the frequency domain with all other tones of the set. The AP may generate an indicator for this RU and may transmit the indicator to the wireless node. The wireless node may receive the indicator, determine the non-contiguous set of tones for the indicated RU, and transmit data over the non-contiguous set of tones for the RU. The AP may receive the data via the RU (over the non-contiguous set of tones).

Abstract: Methods and apparatus for multiple user uplink are provided. In one aspect, a method includes receiving, at a wireless device, a trigger message allocating one or more wireless transmission resources, each resource allocated to a plurality of stations. The method further includes determining whether to transmit over the allocated resources based on a contention procedure. The method further includes selectively transmitting over the allocated resources based on said determining.

Abstract: An access point (AP) may signal management frames that include two operation information fields indicating two channel widths for different classes of wireless stations (STAs). STAs may identify one of the two operation information fields based on capabilities of the STA (e.g., whether or not the STA is capable of dual band channel bonding, resource unit or physical channel puncturing, etc.). In some cases, one operation information field may indicate a channel width within a first and second frequency band (e.g., within the 5 GHz band and the 6 GHz band), as well as a puncturing scheme associated with the channel width. In some cases, the operation information field may indicate a dual band channel bonding configuration, where two frequency segments associated with the channel bonding configuration are in two different frequency bands. In some cases, a tightened spectral mask may be used for such dual band channel bonding configurations.

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: Methods and systems for wireless communication are disclosed. In one aspect, a method includes generating device specific transmission control information for each of two devices, transmitting the transmission control information for each device over different frequencies, and transmitting data to each of the devices as part of a communication according to the respective transmission control information. In some aspects, the transmission control information for each device is encoded based on an identifier of the device. For example, in some aspects, an error detection value such as a cyclic redundancy check, is exclusive or'ed with an identifier of the device, such as an AID, PAID, or group identifier. The resulting value is transmitted along with the transmission control information. A device receiving the wireless frame may only be able to decode its own transmission control information, as the decoding is also based on the receiving device's identifier.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for partial bandwidth feedback based on punctured sounding. Punctured sounding is used by a transmitting device that omits portions of a channel bandwidth based on a puncturing pattern. The puncturing pattern may be based on an exclusion bandwidth zone to avoid transmissions on portions of channels that may interfere with an incumbent system transmission. The puncturing pattern may be indicated in a null data packet announcement (NDPA) to inform the receiving device that a subsequent NDP will be punctured. The receiving device may determine the feedback by measuring the portions of the NDP that are not punctured. Beamforming may be enhanced by using punctured sounding between two beamforming endpoints.
