    摘要: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a smart friend request message to a set of nodes in the wireless mesh network. The set of nodes may be associated with a friend feature that may include maintaining one or more element messages intended for the first node when the first node is in a low power state. Each of the one or more element messages intended for the first node may include an element address corresponding to an element at the first node. The smart friend request message may indicate a hierarchy of element addresses to maintain at the second node. The apparatus may operate in the low power state during which the second node maintains the one or more element messages for the first node based at least in part on the hierarchy of element addresses.

    摘要: The apparatus provided may be a memory circuit. The memory circuit includes a memory cell. The memory cell has a bitline. The memory circuit also includes a write driver. The write driver is configured to drive the bitline to write a bit to the memory cell during a write operation. The write driver is also configured to float the bitline to mask the bit during a read operation. The write driver may use NMOS pullup transistors.

    摘要: Using Bluetooth low energy beaconing to send small amounts of data without establishing a connection works fine for simple beaconing settings, but becomes complex for more complicated beaconing settings. The apparatus may be configured to receive a notification from a wireless device indicating a presence of a wireless device. The apparatus may also be configured to determine at least one of a set of beacon parameters or a beacon content after receiving the notification indicating the presence of the wireless device. Additionally, the apparatus may be configured to transmit a beacon to the wireless device based on the determined at least one of the set of beacon parameters or the beacon content.

    摘要: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an aspect, an apparatus may be configured to transmit a first message that includes a first trigger field to a second wireless device. The first trigger field may indicate whether the first message includes a request for a trigger message to be sent by the second wireless device at a start of a TWT service period. The apparatus may be configured to receive a second message from the second wireless device. The second message may include a second trigger field based on the first message, and the second trigger field may indicate whether the second wireless device will transmit the trigger message at the start of the TWT service period.

    摘要: With the Internet of Things, many devices and/or objects may be connected to each other using any number of wired or wireless technologies. A user may forget a that may be relevant to an upcoming event. The user may benefit from a mechanism that notifies the user when an event is upcoming in which a specific device or object may be germane but is not proximate to the user. Accordingly, an apparatus may identify a set of device types associated with an upcoming event. The apparatus may determine a device type of the set of device types is disconnected from the apparatus. The apparatus may select a device from a set of devices associated with the at least one device type based on a subset of a set of parameters. The apparatus may provide an indication of the selected device associated with the at least one device type.
