Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

Abstract: An electronic device may coordinate access to a shared communication channel with one or more other electronic devices. After receiving frames from the one or more other electronic devices with information specifying back-off values associated with at least an access category for the one or more other electronic devices in a subsequent potential slot transmission opportunity, the electronic device may update a stored list of known occupied back-off values for the subsequent potential slot transmission opportunity. Then, the electronic device may select and may transmit to the one or more other electronic devices an available back-off value for the electronic device in the subsequent potential slot transmission opportunity that is not included in the stored list and that is associated with an access category. Next, during a slot corresponding to the selected back-off value, the electronic device may transmit a second frame to at least another electronic device.

Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

Abstract: The subject technology provides for block acknowledgment requests and block acknowledgment frames that can be used in conjunction with multicast transmissions that include multiple concurrent streams. Thus, the subject technology reduces the overhead associated with multicast transmissions that include multiple concurrent streams by aggregating the acknowledgments across multiple streams into a block acknowledgment, thereby increasing the effective throughput of such transmissions and overall network efficiency.

Abstract: This application relates to electronic devices configured to connect to a wireless local area network and communicate using a trigger-based access mechanism. An access point is configured to manage the wireless local area network. The access point includes a processing subsystem configured to select a channel associated with a communications medium for communicating with the set of electronic devices. The processing subsystem is also configured to monitor the channel to detect interference from radio frequency sources not connected to the wireless local area network, receive channel information for at least one additional channel associated with the communications medium from the electronic devices, and configure an interface circuit of the access point to communicate with the set of electronic devices on a new channel based, at least in part, on the channel information. Each electronic device can be configured to collect the channel information and transmit the channel information to the access point for analysis.

Abstract: Embodiments are disclosed for triggered multi-link (ML) access coordination. A station (STA) ML device (MLD) can establish a preferred triggering link (PTL) with an access point (AP) MLD where the PTL is the preferred link for receiving triggering frames. The STA MLD can transmit uplink (UL) frames via the PTL in response to a trigger frame. Subsequently, the STA MLD can determine that the PTL is busy, and transmit enhanced distributed channel access (EDCA) UL frames on a non-PTL link. In a power save mode, the STA MLD can use the PTL to exchange UL and downlink (DL) frames. Multiple PTLs can be established supporting concurrent trigger frames, and different ranges of traffic IDs (TIDs) can be used for each PTL. The STA MLD can utilize AP MLD link pair information to receive a DL retransmission corresponding to one TID via both links of the AP MLD link pair.

Abstract: An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). The access point receives, from one or more electronic devices in a set of electronic devices, one or more requests to send data. In response, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices. After receiving a frame from the last electronic device in the ordered list of electronic devices or after an unused transmit opportunity of the last electronic device in the ordered list of electronic devices, the access point transmits a block acknowledgment to the ordered list of electronic devices.

Abstract: An access point may receive, from a set of electronic devices, one or more buffer status reports that indicate that at least a subset of the electronic devices have uplink data associated with one or more access categories. In response, the access point may create a group of uplink virtual queues for one or more electronic devices in the subset based on the one or more buffer status reports, where a given uplink virtual queue corresponds to a particular access category and a given electronic device. The access point may start one or more backoff counters with a one-to-one correspondence to uplink virtual queues in the group of uplink virtual queues. When a backoff counter for the given uplink virtual queue reaches zero, the access point may transmit a trigger frame to an electronic device in the subset that corresponds to the given uplink virtual queue.

Abstract: Some aspects include apparatuses and methods for implementing a target wake time (TWT) scheme (or technique) for multi-link wireless communication networks. For example, a multi-link device (MILD) includes a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link using a multi-link target wake time (TWT) process. The MLD also includes a second STA associated with a second link of the wireless network and configured to communicate with the second MLD over the second link using the multi-link TWT process. The MLD further includes one or more processors communicatively coupled to the first and second STAs and configured to control the operations of the first and second STAs to perform the multi-link TWT process.

Abstract: The subject disclosure provides systems and methods for low-latency point-to-point communication between electronic devices. In one or more implementations, low latency can be achieved by including data in transmission units, in order of priority up to a maximum duration for the transmission unit. In an example in which the communication occurs over a WiFi channel, the transmission unit may be a multi-TID AMPDU, and the priority may be based on a Quality of Service (QoS) category as identified by the traffic identifier (TID). The communication may be exchanged using a periodic access window that can be adaptively offset, to efficiently share bandwidth with other device pairs on the same wireless channel. Base and client devices can be time synchronized, and transmission opportunity (TXOP) bursting can be allowed, in one or more implementations.
