Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improved handling of adjacent channel interference in multi-link aggregation scenarios. In accordance with the described techniques, a device may establish a set of wireless links for communication with a second device, the set of wireless links supporting parallel transmission during at least a first duration of a multi-link session, the set of wireless links including at least a first wireless link and a second wireless link. The device may modify a transmission parameter for the first wireless link or a clear channel assessment (CCA) parameter for the second wireless link, or a combination thereof. The device may then perform the CCA procedure on the second wireless link and transmit at least a first portion of the message on the first wireless link based on the modified transmission parameter or modified CCA parameter.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QoS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). In some aspects, a first WLAN device may transmit a first HARQ frame to a second WLAN device. The first WLAN device may determine whether a first feedback message received from the second WLAN device includes HARQ acknowledgement information or non-HARQ acknowledgment information. The first feedback message may be a HARQ Block Acknowledgement (H-BA) message having a multi-station Block ACK (M-BA) frame format that includes HARQ acknowledgment information. The first WLAN device may transmit a second HARQ frame to the second WLAN device in response to determining the first feedback message includes the HARQ acknowledgment information. The first WLAN device may transmit a non-HARQ frame in response to determining the first feedback message includes non-HARQ acknowledgement information.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for per-station punctured transmissions. A wireless local area network (WLAN) device may determine available resource units (RUs) within a wireless channel that has a punctured frequency range. The WLAN device may allocate a plurality of RUs, from among the available RUs, for to include data for a same station. For example, a physical layer protocol data unit (PPDU) may include more than one RU for a first station. The RUs that are allocated to the first station may exclude the punctured frequency range. In some implementations, the plurality of RUs may be separated by at least the punctured frequency range. A signaling header in the PPDU may indicate which RUs are allocated to the first station. By allocating a plurality of RUs in a PPDU, a WLAN may support per-station puncturing within the PPDU.

Abstract: In some aspects, methods and apparatus for wireless communications are configured to generate a packet for wireless communication where the packet includes a mark symbol in a preamble of the packet where the mark symbol includes a signature or stamp field in the mark to provide protocol information that indicates the protocol of the packet, such as an 802.11 EHT packet. In some other aspects, a cyclic redundancy check field in the mark symbol may be manipulated in various ways to indicate the protocol of the packet in lieu of providing the signature or stamp field.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for managing high volumes of space-time-streams in Wi-Fi systems. An access point (AP) may transmit packets including long training field (LTF) sections using a number of space-time-streams greater than eight. Mobile stations (STAs) in the system may or may not be capable of processing this number of streams. The AP may modulate an LTF section using a matrix with dimensions smaller than the number of streams by using tone-interleaving or by performing modulation with separate matrices in time and frequency. In some other implementations, the AP may split the antennas for transmission into groups, each group transmitting either different packets in a subset of streams or a same packet in a subset of tones. In further implementations, the AP may combine multiple space-time-streams into a super stream that supports reception at different types of STAs.

Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.
