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: The disclosed embodiments provide a system that provides wireless service groups. During operation, a wireless device's advertising mechanism advertises a service group over Wi-Fi, wherein the service group comprises at least the wireless device and wherein the service group's security requirements regulate multicast protection within the service group. In response to receiving a request from a second device to be admitted into the service group, the wireless device's security mechanism admits the second device into the service group and sends the service group's security requirements to the second device, thereby enabling the second device to initialize multicast protection in accordance with the service group's security requirements.

Abstract: Embodiments described herein relate to providing reduced power consumption in wireless communication systems, such as 802.11 WLAN systems. Timing information regarding power save opportunities (PSOPs) may be provided in communication frames, which may inform mobile devices of expected frame exchange periods during which they may transition to a Doze state. Additional PSOP information may be included in beacon frames, which may inform mobile devices of expected multicast periods during which they may transition to a Doze state. This may operate to provide improvements in terms of power consumption.
Abstract translation: 本文描述的实施例涉及在诸如802.11 WLAN系统的无线通信系统中提供降低的功率消耗。 可以在通信帧中提供关于省电机会（PSOP）的定时信息，通信帧可以向移动设备通知其可能转换到打盹状态的预期帧交换周期。 附加的PSOP信息可以被包括在信标帧中，这可以通知移动设备预期的多播时段，在此期间，它们可以转换到打盹状态。 这可以在功率消耗方面提供改进。

Abstract: A method and apparatus are provided for conducting peer-to-peer communications while channel hopping among two or more wireless channels, at least one of which is a restricted channel. One type of restricted channel requires the use of DFS (Dynamic Frequency Selection) or a similar scheme for avoiding use of the channel during certain circumstances (e.g., for radar avoidance). Communicating peers may synchronize a channel-hopping sequence with TBTTs (Target Beacon Transmission Times) of the restricted channel(s), so that they switch to such a channel in time to capture a beacon and determine whether the channel is free. If the channel is free, or if no beacon is received, they may immediately begin or resume their communications. They may also quiesce just before another TBTT so as to capture that beacon. Thus, the peer-to-peer communications do not diminish a peer device's ability to receive and comply with channel switch announcements.
Abstract translation: 提供了一种方法和装置，用于在两个或更多个无线信道中的信道跳跃期间进行对等通信，其中至少一个是受限信道。 一种类型的受限通道需要使用DFS（动态频率选择）或类似的方案来避免在某些情况下使用信道（例如用于雷达避免）。 通信对等体可以将信道跳跃序列与受限信道的TBTT（目标信标传输时间）同步，以便及时切换到这样的信道以捕获信标并确定信道是否空闲。 如果频道是空闲的，或者如果没有收到信标，他们可以立即开始或恢复通信。 他们也可能在另一个TBTT之前停顿，以便捕获该信标。 因此，对等通信不会削弱对等设备接收和遵守信道切换通告的能力。

Abstract: A system and method for peer-to-peer communications is disclosed. A first wireless device receives a message from a second wireless device identifying communication requirements of a point-to-point communication involving the second wireless device. The first wireless device determines whether the second wireless device's communication requirements can be satisfied based on communication resources already committed for other communications. When the communication requirements of the second wireless device can be satisfied, the first wireless device generates a time sharing schedule to be used by the first and second wireless devices based on the already-committed communication requirements and the second device's communication requirements. The time sharing schedule may include a first portion for broadcast communication among a group of devices to which the first and second wireless devices belong, and a second portion for the point-to-point communications of the second wireless devices.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) technique for multicast communication. For example, some embodiments relate to a method including configuring a target wake time (TWT) process for delivering one or more multicast packets to a group of electronic devices. The method further includes determining that a service period associated with the TWT process has started and transmitting, in accordance with the TWT process, the one or more multicast packets during the service period, where the one or more transmitted multicast packets are addressed to the group of electronic devices.

Abstract: An apparatus comprises a memory and at least one processor in communication with the memory. The at least one processor is to detect, during a discovery window, a neighboring client station that is to perform peer-to-peer Wi-Fi communication via a Neighbor Awareness Networking (NAN) protocol and establish, via a negotiation after the discovery window, a datapath with the neighboring client station, wherein the negotiation includes an exchange of NAN data path setup attributes in parallel with an exchange of encryption cipher attributes and the encryption cipher is based on a simultaneous authentication of equals (SAE) protocol. The SAE protocol can be used to generate key material to encrypt the datapath.

Abstract: An interface circuit in an electronic device (such as an access point) may receive a setup request associated with the recipient electronic device. The setup request may specify a group address for which the recipient electronic device wants to receive associated frames and a proposed transmission interval. Based at least in part on the proposed transmission interval, the electronic device may determine a transmission schedule and/or may assign, based at least in part on the group address, the recipient electronic device to an aggregated group having a flexible multicast service identifier (FMSID). Then, the electronic device may provide a wake-up frame for the recipient electronic device, where the wake-up frame includes an identifier of the aggregated group for which a group-addressed frame will subsequently be transmitted by the electronic device. Moreover, the wake-up frame may be provided at a transmission time based at least in part on the transmission schedule.
