Abstract: This application relates to techniques that adjust the sleep states of a computing device based on proximity detection and predicted user activity. Proximity detection procedures can be used to determine a proximity between the computing device and a remote computing device coupled to the user. Based on these proximity detection procedures, the computing device can either correspondingly increase or decrease the amount power supplied to the various components during either a low-power sleep state or a high-power sleep state. Additionally, historical user activity data gathered on the computing device can be used to predict when the user will likely use the computing device. Based on the gathered historical user activity, deep sleep signals and light sleep signals can be issued at a time when the computing device is placed within a sleep state which can cause it to immediately enter either a low-power sleep state or a high-power sleep state.

Abstract: A first wireless communication device (UE device) associated with a certain user (or included in a specified set/group of UE devices) may establish a first communication link with an accessory device according to a short-range radio access technology, and transmit link (pairing) information associated with the first communication link to a server, such as a cloud-based server. The server may share this (first) link information with other UE devices associated with the same user (or belonging to the same specified group of UE devices as the first UE device). Link information associated with the other UE devices (i.e. second link information) may equally be shared with the accessory device, and the other UE devices and accessory device may use the first link information and second link information in establishing respective communication links between any of the other UE devices and the accessory device without having to undergo a pairing procedure.

Abstract: In order to reduce latency and overhead during the device discovery process, operations involved in pairing of two electronic devices may be predefined. In particular, when a user specifies a new electronic device in a list of their electronic devices, a computer provides a notification to these electronic devices. In response to the notification, a given one of the electronic devices generates encryption information and identification information for the given electronic device, and provides this encryption information and identification information to the new electronic device via a network (such as the Internet). Then, the new electronic device generates encryption information and identification information for the new electronic device, and provides this encryption information and identification information to the given electronic device via the network. This pairing information may subsequently facilitate secure wireless communication between the two electronic devices.

Abstract: An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface devices.

Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a device to transmit, via a BTLE (or Bluetooth) interface, a first message indicating an operation associated with a Wi-Fi service (e.g., a service available via a Wi-Fi interface and/or Wi-Fi related interface parameters) to a peer device. The first message may include a service hash that indicates the operation. The service hash may be included in a first data structure. The first data structure may indicate availability of the Wi-Fi service. The device may receive a second message from the peer device indicating that the neighboring wireless station intends to subscribe to or provide the Wi-Fi service, e.g., via Wi-Fi peer-to-peer communications.

Abstract: In order to reduce the power consumption of a receiving electronic device, received advertising beacons may be filtered so that the receiving electronic device selectively transitions from a power-saving mode to a normal operating mode. For example, the receiving electronic device may receive a beacon with advertising information for a transmitting electronic device. If the advertising information is changed relative to a previous version of the advertising information for the transmitting electronic device, the receiving electronic device may transition from the power-saving mode to the normal operating mode. In this way, the receiving electronic device may ‘wake up’ if it receives an advertisement that it wants to act on, such as advertisements for: file sharing, wireless streaming of information, proximity pairing and/or continuity of a user experience with an application when the user transitions from the transmitting electronic device to the receiving electronic device.
