Abstract: This disclosure provides methods, devices and systems for data parsing for resource unit (RU) aggregation. A wireless communication device (such as an access point (AP) or a station (STA)) may allocate a set of resource units (RUs) for a receiving device in a basic service set (BSS). The set of RUs may be associated with multiple bandwidth segments of a bandwidth allocation and may be non-contiguous or contiguous. The wireless communication device may determine a data parsing and encoding scheme for a set of information bits. In some implementations, the encoded bits may be distributed to the set of RUs based on a distance to tone mapping value or pilot tone location or both of the aggregated set of RUs different than respective values or pilot tone locations of the RUs in the aggregated set of RUs.

Abstract: This disclosure provides methods, devices and systems for generating enhanced sounding packets. Some implementations more specifically relate to sounding packet designs that support enhancements to wireless communication protocols associated with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced null data packet announcement (NDPA) frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, the enhanced NDPA frame may be configured in accordance with a legacy or a non-legacy NDPA frame format. In some other implementations, the enhanced NDPA frame may include a subfield carrying information identifying a particular basic service set (BSS) which may be associated with one or more STA information fields. Still further, in some implementations, an Extremely High Throughput (EHT) PPDU may include signaling to indicate whether the EHT PPDU is formatted as a sounding NDP.

Abstract: This disclosure provides methods, components, devices and systems for extending distributed resource units (dRUs) beyond 80 MHz. Some aspects more specifically relate to supporting enhanced tone distribution mapping schemes and signaling. In some examples, a wireless station may receive, from an access point, scheduling information for a physical layer (PHY) protocol data unit (PDU) (PPDU) to be transmitted by one or more wireless stations including the wireless station over a wireless channel. The scheduling information may indicate one or more dRUs within the wireless channel, each dRU comprising a respective set of tones distributed across a distribution bandwidth of the wireless channel. The distribution bandwidth may be larger than 80 MHZ, and the one or more dRUs including a first dRU allocated to the wireless station. The wireless station may modulate a plurality of symbols for the PPDU onto the set of tones of the first dRU. The wireless station may transmit the plurality of symbols via the first dRU.

Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may transmit, to a second AP and during a first portion of a transmission opportunity (TxOP), a request to participate in a multi-user (MU) transmission. The AP may receive, from the second AP and during the first portion of the TxOP, an indication of intent to participate in the MU transmission during the second portion of the TxOP, the indication of intent including a resource request of the second AP for participation in the MU transmission. The AP may transmit, during an initial period of the second portion of the TxOP, a trigger signal to the second AP indicating a set of one or more resources for the second AP during the MU transmission. The AP may participate, in conjunction with the second AP and during the second portion of the TxOP, in the MU transmission.

Abstract: This disclosure provides wireless communication methods, components, devices and systems for applying spectral masks and spectral flatness parameters in conjunction with transmission of millimeter wave (mmWave) signals in wireless communication networks. In some examples, in conjunction with transmission of an mmWave signal, a wireless communication device can apply a derivative spectral mask featuring transitional offset ranges that correspond to transitional frequency offset ranges of a spectral mask for a nominal carrier signal, scaled according to a ratio between a bandwidth of the mmWave signal and a bandwidth of the nominal carrier signal. In some examples, the derivative spectral mask can feature an in-band frequency offset range that is wider than a scaled width of an in-band frequency offset range of the spectral mask for the nominal carrier signal.

Abstract: This disclosure provides methods, components, devices and systems for physical layer (PHY) latency reduction. Some aspects more specifically relate to PHY protocol data unit (PPDU) designs that support inserting low-latency traffic into a transmission opportunity (TXOP) occupied by non-low-latency traffic. In some implementations, during a TXOP, an access point (AP) may output an aggregated PPDU (A-PPDU) that is aggregated in a time domain and includes an A-PPDU header and one or more A-PPDU subframes. The AP may obtain, from an application layer, a low-latency PPDU (LL-PPDU) subframe and may insert the LL-PPDU subframe in place of at least one of the one or more A-PPDU subframes. The AP may output the LL-PPDU subframe during the TXOP. A wireless station (STA) receiving the A-PPDU header and the one or more A-PPDU subframes may detect the presence of the LL-PPDU subframe and may receive and decode the LL-PPDU subframe.

Abstract: This disclosure provides methods, devices and systems for amplitude shaping encoding, and specifically, for indicating boundaries in bitstreams encoded using amplitude shaping encoding. In some aspects, a transmitting device may insert, into an bitstream to indicate a boundary, a sequence of amplitude bits not associated with any patterns of bit values in a lookup table used for the encoding. In some other aspects, a transmitting device may monitor a length of the amplitude bits in a bitstream during the encoding and stop the encoding on information bits at an end of a current data unit responsive to the length reaching a threshold. In some other aspects, a transmitting device may monitor the length of the information bits and, for each data unit, determine whether a boundary is or would be reached. Responsive to determining that a boundary is or would be reached, the transmitting device may not include, before the boundary, any amplitude bits generated based on the information bits in the data unit, and instead add padding bits after a last amplitude bit before the boundary.

Abstract: Methods, systems, and devices for wireless communication are described. An encoding device may obtain a first set of coded bits by encoding multiple sets of information bits in accordance with a parallel encoding scheme. The encoding device may obtain a second set of coded bits by using some or all of the first set of coded bits to encode a second set of information bits in accordance with a concatenated encoding scheme. The encoding device may map at least the second set of coded bits to different layers of a constellation based on a first priority associated with the first set of coded bits and a second priority associated with the second set of coded bits. Accordingly, the encoding device may transmit a signal associated with the second set of coded bits based on modulating the signal in accordance with the mapping.
