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: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.

Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

Abstract: In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling may include determination of a type of datapath, including paging and synchronized datapaths. NAN data cluster base schedules may be scheduled as equal-sets or subsets of datapath schedules. The datapath model may be implemented for unicast and multicast communication between client stations.

Abstract translation: 一个或多个客户站操作以配置邻居感知网络（NAN） - 与相邻客户站直接通信，即在不利用中间接入点的情况下在客户站之间的直接通信。 本公开的实施例涉及NAN数据路径调度和NAN预数据路径操作设置和调度。 这里描述的NAN数据路径实施例提供了一种机制，通过该机制可以进行通信并提供服务。 数据路径开发的方面包括数据路径调度，包括数据路径设置和调度属性，以及预先数据路径操作触发和调度。 调度可以包括确定数据路径的类型，包括分页和同步的数据路径。 NAN数据集群基础调度可以被调度为数据路径调度的等同集或子集。 数据通路模型可以用于客户站之间的单播和多播通信。 协商窗口可以布置在装置和客户端设备之间，以便配置直接Wi-Fi通信而不涉及Wi-Fi接入点。 如果邻近客户站指示第一客户站期望的一个或多个服务的可用性，则第一客户站可以请求到邻近客户站的连接。

Abstract: Methods, systems and apparatuses for performing a encryption and/or protection of MAC headers and/or control frames are described. A wireless device can determine a randomized MAC address and offset to obfuscate MAC headers and/or control frames, e.g., which can change at different times/intervals. The wireless device can determine an encryption block pattern, which can be based on an encryption key and/or nonce. The wireless device can encrypt the MAC header and/or control frame. Similarly, a receiving device can receive an encrypted MAC header and/or control frame and decrypt it according to corresponding techniques.

Abstract: Methods, systems and apparatuses for performing an address change by an access point (AP) multi-link device (MLD) and non-AP MLD are described. A non-AP MLD may transmit to an AP MLD, using one or more respective transmission (TX) links in an active mode, one or more uplink frames that include one or more respective initial addresses corresponding to one or more respective reception (RX) links of the AP MLD. The non-AP MLD may then configure the one or more respective TX links to a lower power mode. The non-AP MLD may configure the one or more respective TX links with one or more respective new addresses prior to transitioning the one or more respective TX links back to the active mode. The non-AP MLD may transmit, to the AP MLD, one or more additional uplink frames that include the one or more respective new addresses.
