    Abstract: Methods, systems, and devices for wireless communications are described. Techniques may include transmitting, from an access point (AP) to a first set of stations (STAs) a first message soliciting an uplink transmission by the first set of STAs over a wireless channel, transmitting to a second set STAs a second message including an instruction to monitor the wireless channel for interference during the uplink transmission by the first set of STAs; transmitting to the second set of STAs a third message triggering an interference report; and receiving an interference report based on the second and third messages. Techniques include identifying a plurality of sectors of a geographic coverage area corresponding to the AP; transmitting a set of directional training signals; receiving a signal to noise ratio (SNR) report from multiple STAs; comparing the received SNR reports on a per sector basis; and adjusting communication based on the comparing.

    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: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a wakeup radio (WUR) frame for the STA at a WUR. The STA may identify, from a number of packet number generation schemes, a scheme that the STA is to use to construct a packet number for the WUR frame. Following the scheme identification, the STA may generate a packet number for the received WUR frame using the identified scheme and determine whether to discard the WUR frame based on the generated packet number. In some implementations, the STA may determine whether the STA is to use, for communications received from an access point (AP) to the WUR, a same key or a second key, the second key being different from a first key used by the STA to receive protected communications from the AP to a primary radio of the STA.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.

    Abstract: A wireless station may buffer data associated with one or more traffic identifiers (TIDs), and generate a media access control (MAC) protocol data unit (MPDU) including TID-specific buffer status report (BSR) information. A BSR control field may include an Access Category Identifier (ACI) bitmap and a delta TID parameter indicating a mapping of TID-specific buffer status information to a first and second queue size indicated by the BSR. In some cases, the MPDU may also include a quality of service (QoS) control field, and queue sizes indicated by the BSR control field and QoS control field may be accumulated for reporting buffer status for a TID. Additionally or alternatively, a transmitting wireless station may generate an aggregated MPDU (A-MPDU) including multiple MPDUs with different A-control fields based on a receiving a capabilities information field indicating a number of different aggregated control (A-Control) fields the receiving wireless station supports.

    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support a 20 MHz station (STA) parked on a secondary channel. Without the described techniques, mechanisms to support secondary channel operation may be unable to receive management frames or broadcast traffic from an access point (AP), which may cause the STA to lose synchronization with the AP, miss a channel change or other critical announcement from the AP, etc. Considerations for providing such information to STAs parked on a secondary channel are discussed. In some examples, an AP may restrict resource unit allocation to the secondary channel on which the STA is parked. In some cases, a trigger-based random access mechanism may utilize aspects of the present disclosure to limit access to certain resource units to STAs on a given secondary channel.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for establishing communications with one or more devices. In one aspect, a first device generates a wake-up radio (WUR) frame, the WUR frame including a media access control (MAC) header and a frame check sequence (FCS) having a cyclic redundancy check (CRC) or a message integrity check (MIC). The first device may determine the FCS based, at least in part, on the MAC header and basic service set identifier (BSSID) information associated with the first device. The first device may output the WUR frame for transmission to one or more devices. A second device may receive the WUR frame from the first device and determine whether the WUR frame is directed to the second device based, at least in part, on comparing the FCS of the WUR frame with a calculated FCS.
