Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

Abstract: A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.

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: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing wireless devices. A service is provided by a first application operating on a publisher device to a second application operating on a subscriber device over a first data path between the two devices in a NAN network. The publisher device includes a first recovery manager to receive an indication from a wireless controller of the publisher device or a distress message from a second recovery manager of the subscriber device. The received indication or distress message indicates that the first data path has been interrupted. The first recovery manager stores, in a memory, data generated by the first application. A second data path is established between the publisher device and the subscriber device. The first recovery manager sends the stored data to the second application that operates on a subscriber device.

IPC: H04W74/08
Abstract: During operation, an electronic device (e.g., an access point) may provide a multi-user (MU)-request-to-send (RTS) frame that communicates an RTS in a channel associated with the second electronic device and a second RTS in a second channel associated with a third electronic device. For example, the channel may include a primary channel and the second channel may include a secondary channel. Note that the third electronic device may include a SST station and the second electronic device may include a non-SST station. Then, the electronic device may receive an MU-clear-to-send (CTS) frame that includes a CTS in a third channel associated with the third electronic device. Moreover, the third channel may be equal to or a subset of the second channel, and/or the third channel may include a CTS reception channel associated with the electronic device.

Abstract: A recipient electronic device that provides an acknowledgment is described. This recipient electronic device may include a main radio and a wake-up radio (WUR) that at least selectively transitions the main radio from a lower-power mode to a higher-power mode in response to a wake-up frame. During operation, the WUR receives a wake-up frame associated with an electronic device, e.g., a second or a sending device. Then, the WUR provides, in response to the wake-up frame, the acknowledgement intended for the electronic device. The wake-up frame may specify that an acknowledgement from the recipient electronic device to the electronic device is expected. For example, the wake-up frame may specify that the acknowledgement is communicated by the recipient electronic device using the WUR in the recipient electronic device. Moreover, the WUR may provide the acknowledgment while the main radio is in the lower-power mode.

Abstract: An electronic device (such as an access point) may provide a management frame, intended for at least a recipient electronic device, that includes slotted-operation information corresponding to a power-save mode of the electronic device for communication with at least the recipient electronic device. The slotted-operation information may include a sequence of temporal slots and associated channel information for the temporal slots. When a channel for a temporal slot comprises a null value, the power-save mode may include transitioning the electronic device into a lower-power-consumption mode during the temporal slot. Alternatively, when a channel for a temporal slot is different than a null value, the power-save mode may include performing another activity than communicating with the recipient electronic device during the temporal slot.
