Abstract: A method and apparatus for re-associating a station (STA) to an access point (AP). The STA sends a re-association request to the AP to initiate a re-association process with the AP. The re-association request indicates that a handshake operation is to be bypassed during the re-association process. The STA receives a re-association response from the AP in response to the re-association request and, upon receiving the re-association response, enables data communications with the AP using a set of preexisting cryptographic keys. For example, the set of preexisting cryptographic keys may be negotiated with the AP during at least one of a prior association process or a prior re-association process.

Abstract: A method and apparatus to save power in a soft access point for a network. If no network traffic is detected for an integral number of TBTT (Target Beacon Transmission Time) intervals immediately prior to a current TBTT interval, and if no network traffic is detected for a first time slot in the current TBTT interval, then the soft access point sends a CTS (Clear-to-Send) packet addressed to itself to quiet the network for a second time slot and enters a low power mode for the second time slot. At the beginning of a third time slot, the soft access point puts itself into an active mode and monitors network traffic.

Abstract: A wireless device implements power saving logic for two or more wireless clients that concurrently communicate on a shared wireless channel (single channel concurrency). When one of the wireless clients transitions from power save mode to active mode (e.g., in response to a beacon signal), the power saving logic causes the other wireless client(s) to transition to active mode as well. Each wireless client ‘awakened’ in this manner transmits a NULL frame having a power management bit set to a logic ‘0’ value to an associated access point (AP), thereby indicating its active status to the associated AP. As a result, all of the wireless clients may concurrently receive buffered data from their associated APs on the shared wireless channel. If the ‘awakened’ wireless client(s) do not need to transition to active mode in response to their next received beacons, power consumption of the wireless device is advantageously reduced.

Abstract translation: 无线设备为在共享无线信道（单信道并发）上同时通信的两个或更多个无线客户端实现功率节省逻辑。 当其中一个无线客户端从省电模式转换到活动模式（例如，响应于信标信号）时，功率节省逻辑也使另一无线客户端转换到活动模式。 以这种方式“唤醒”的每个无线客户端将具有设置为逻辑“0”值的功率管理位的空帧发送到相关联的接入点（AP），从而向相关联的AP指示其活动状态。 结果，所有无线客户端可以并发地从共享无线信道上的相关AP接收缓冲数据。 如果“唤醒”的无线客户端不需要响应于其下一个接收的信标转换到主动模式，则有利地减少了无线设备的功率消耗。

Abstract: Methods, systems, and devices are described for wireless communication at an access point (AP). The AP may snoop messages between stations (STAs) and a network. Using information obtained from snooping, the AP may identify which STAs are interested in receiving different multicasts. Accordingly, the AP may generate and maintain a table that maps multicasts to interested STAs. The AP may assign a unique group identity (ID) to STAs interested in a multicast and include the group ID in the frame header of frames for that multicast which are broadcast to the STAs. Thus, STAs interested in receiving the multicast will recognize the group ID in the frame header and decode the entire multicast frame; STAs not interested in receiving the multicast will avoid decoding and processing the entire multicast frame. The AP may also use beamforming to direct the multicast frames to interested STAs and away from uninterested STAs.

Abstract: This disclosure provides methods, devices and systems for scheduling delivery of buffered multicast data to wireless stations (STAs) associated with an access point (AP). In some implementations, a STA transmits, to the AP, a request frame including a multicast address of a multicast group. The AP transmits, to the STA, a Group Identification (ID) assigned to the multicast group. The AP transmits a beacon frame including a wake-up schedule indicating times at which one or more STAs belonging to the multicast group are scheduled to receive buffered multicast data from the AP. STAs that belong to the multicast group wake up at one of the indicated times for a Target Wake Time (TWT) Service Period (SP). STAs that do not belong to the multicast group remain in power save mode during the TWT SP. The AP transmits the buffered multicast data at the indicated time during the TWT SP.
