Abstract: Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point may assign a channel weighting factor to each channel in a candidate channel list. The access point may identify an attribute of a radar signal detected on a current operating channel. The access point may adjust, based at least in part on the identified attribute, the channel weighting factor assigned to a channel of the candidate channel list adjacent to the current operating channel. The access point may select a new operating channel from the candidate channel list based at least in part on the assigned channel weighting factor.

Abstract: A wireless device may be configured to operate in one of two modes where each mode uses a different channel list to perform operations in accordance with the IEEE 802.11 standard. In a first mode, the wireless device operates as an access point that sets up channels using one channel list in order to facilitate communications within a basic service set (BSS). In a second mode, the wireless device uses a second channel list to operate as a station and scan for a BSS. The first channel list contains a subset of the channels contained in the second channel list. The channels in each respective channel list may be reconfigured to adapt to changes in the configuration of a BSS and the devices communicating therein.

In one embodiment, such a wireless transmitter can include encoding components for receiving transmit data and generating encoded data.

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: 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.
