Disclosed is an improved implementation of a flood fill mesh network that utilizes probability forwarding for rebroadcasting network messages. The forwarding probability may be determined based on analyzing a network topology map constructed by each network node relative to its neighbor nodes communicating on the network and derived from state information contained in synchronization frames broadcasted by the network nodes on the network. The forwarding probability may comprise a statistical probability that a message frame received by a network node will be forwarded to the intended destination network node by one or more of the network node's neighbor network nodes.

Implementations set forth herein relate to management of casting requests and user inputs at a rechargeable device, which provides access to an automated assistant and is capable of rendering data that is cast from a separate device. Casting requests can be handled by the rechargeable device despite a device SoC of the rechargeable device operating in a sleep mode. Furthermore, spoken utterances provided by a user for invoking the automated assistant can also be adaptively managed by the rechargeable device in order mitigate idle power consumption by the device SoC. Such spoken utterances can be initially processed by a digital signal processor (DSP), and, based on one or more features (e.g., voice characteristic, conformity to a particular invocation phrase, etc.) of the spoken utterance, the device SoC can be initialized for an amount of time that is selected based on the features of the spoken utterance.

An information processing apparatus includes: a sub controller; a main controller; and a communication interface, the main controller being configured to detect a trigger to start the sleep mode, then create port-dependent TCP packet patterns and port-dependent UDP packet patterns, the port-dependent TCP packet patterns being packet patterns specifying all in-use TCP ports, the port-dependent UDP packet patterns being packet patterns specifying all in-use UDP ports, determine that a total number of the port-dependent UDP packet patterns and the port-dependent TCP packet patterns exceeds a maximum value, then delete all the port-dependent TCP packet patterns, create port-independent TCP packet patterns for different TCP protocols, respectively, the port-independent TCP packet pattern being one packet pattern specifying no TCP port, and supply the port-dependent UDP packet patterns and the port-independent TCP packet patterns to the sub controller, and start the sleep mode.

Disclosed is an improved implementation of a flood fill mesh radio network that utilizes message age disambiguation to prevent unnecessary propagation of repeated messages in the network. A digital counter may be used to generate a sequence of numbers based on counter values and the counter values may be associated with each message frame that is broadcast into the mesh network. The domain of generated sequence numbers can be divided up into low and high subdomains and the maximum number of message frames broadcast by a network node in the mesh network may be constrained so that no two messages broadcast by a network node remain circulating in the network longer than that required for the digital counter to wrap back to zero. Under this paradigm the counter values associated with each message can be compared to determine the relative age of the message frames to detect repeated messages.

Disclosed is an improved implementation of a flood fill mesh network that utilizes low power and does not require any network addressing or routing protocol for network message delivery. Network messages are only communicated to a network node's correspondents using broadcast network messages over a wireless network. Network messages propagate throughout the network based on each correspondent node rebroadcasting received messages to its correspondent nodes, and so on. Coordinated synchronization across network nodes can be achieved by each network node broadcasting synchronization frames to its correspondents within a synchronization window time period and thereafter adjusting its own start time for the next synchronization period to converge synchronization. A guard band may also be utilized to account for any clock drift and signal path delays between any two communicating network nodes.

In aspects of managing FTM frames of WLAN RTT bursts, a device can receive a WLAN RTT burst, such as initiated by a device application, device firmware, or received as a RTT ranging request. The device implements a status module that interposes the routing of the ranging request in the device, and determines a device state of the device with a device state monitor of the status module. The status module is implemented to drop the ranging request if the device is an idle device state such that the ranging request is extraneous. Alternatively, the status module is implemented to reduce a number of FTM frames in the ranging request based on the device state indicating that multiple FTM frames of the ranging request are extraneous, and then route to perform the ranging request of the WLAN RTT burst with the reduced number of FTM frames in the ranging request.

Provided are wake-up radio systems and methods based on backscatter wake-up radio. The wake-up radio method based on backscatter wake-up radio includes setting an arbitrary receiving window period in a window setting period by receiving a beacon signal from a data collection apparatus, transmitting a backscatter response message to the data collection apparatus based on a reception time of a contention signal received from the data collection apparatus in the set receiving window period, in the window setting period, and receiving a wake-up signal from the data collection apparatus in the data transmission period to set as a wake-up period and transmitting data to the data collection apparatus based on a scheduling time according to a backscatter response message.

Technology for a user equipment (UE) operable to report periodic channel state information (CSI) to an eNodeB is disclosed. The UE can determine a reporting period (N.sub.pd) of a serving cell of the UE. The UE can determine a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE. The UE can encode multiple periodic CSI reports for transmission to the eNodeB using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period N.sub.pd.

A channel selection method and a transmit end are provided. The method includes: ranking multiple channels, and generating a backoff count value; sequentially decrementing, from an initial timeslot, the backoff count value in each timeslot according to a ranking sequence of the channels and busy/idle states of all the channels until the backoff count value is 0; and selecting, from the multiple channels according to a result of the decrement performed on the backoff count value and a busy/idle state of at least one of the multiple channels, a channel that is used by the transmit end for sending data. The method and the transmit end can improve channel utilization.
