In vehicle-to-vehicle (V2V) or vehicle-to-everything (V2X) communication, the vehicle may wirelessly transmit a signal. However, transmission of a signal using a fixed transmit power may not be desirable. The transmit power should be adjusted based on various factors such as a vehicle speed and a priority level of the vehicle. The apparatus may be a device capable of wireless communication, and may be in a vehicle. The device determines one or more parameters associated with a vehicle including the device, the parameter including at least one of a speed of the vehicle or a priority level of the vehicle. The device sets a transmit power of the device based on the one or more parameters. The device transmits a message via wireless communication using the set transmit power.

In an embodiment, a server monitors a set of parameters associated with future power production capacity of a set of distributed power production units that belong to a power group supplying power to a given serving area of a power grid during a given period of time. The server predicts, for a portion of the given period of time, a temporary power production disruption that will affect the power group based on the monitoring. The server sends a control message to the power group based on the prediction. At least one power production unit in the power group receives the control message, and responsive to the control message diverts at least a portion of power being supplied to the given serving area to local storage, detects the temporary power disruption and conditions power supplied to the given serving area during the temporary power distribution based upon the locally stored power.

A method of data transmission according to one embodiment of the invention includes encoding a set of data values to produce a corresponding series of ordered n-tuples. The method also includes transmitting, according to the series of ordered n-tuples, a plurality of bursts over a plurality n of frequency bands. Specifically, for each of the plurality of bursts, a frequency band occupied by the burst is indicated by the order within its n-tuple of an element corresponding to the burst. A bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. Information is encoded into an additional modulation, e.g., amplitude, width or polarization modulation, of at least one of the plurality of bursts.

A method of data transmission according to one embodiment of the invention includes transmitting a plurality of bursts to transmit data, each burst occupying at least one of a plurality of frequency bands. Specifically, a bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. In one preferred embodiment, a bandwidth of at least one of the plurality of bursts is at least 100 MHz. In another preferred embodiment, each burst occupies at least one of the plurality of frequency bands, but less than all of the plurality of frequency bands.

A method and apparatus for operation in a multi-frequency band wideband system in the presence of an interference, the method comprising the steps: receiving signaling in a plurality of wideband frequency sub-bands, each wideband frequency sub-band having a different center frequency, wherein a bandwidth of each wideband frequency sub-band is at least 2 percent of a center frequency of the wideband frequency sub-band; detecting an interfering signal having signal energy in a portion of a respective sub-band of the wideband frequency sub-bands; modifying at least one of a center frequency and a bandwidth of the respective sub-band in order to operate in the presence of the interfering signal; and instructing a transmitting device transmitting the signaling to transmit subsequent signaling accounting for the modification of the center frequency of the respective sub-band.

A control method, apparatus, and system capable of securely distributing a shared secret network encryption key from a host to a wireless peripheral device. The sharing of the secret network encryption key is accomplished without the intervention of a man-machine interface at the peripheral. Embodiments enable a wireless device to receive and store multiple encryption keys, to select the appropriate encryption key depending on the network in range of the device, and thus to freely associate with multiple networks.

A polling method, apparatus, and system to detect the attachment and detachment of Universal Serial Bus devices in a wireless system. A hub provides a wired connection to the host and wireless attachment points for its devices, The host periodically queries the hub for changes in the hub's status register by sending a polling message through each of its wireless ports, and awaits a response. A peripheral device that wishes to attach to the system responds by sending its unique peripheral address. If a device currently occupies the port, the hub sends out the device's unique address in the polling message. If the device is still present, it responds by sending its unique peripheral address. If a response is not received after multiple retries, the device is considered detached. The hub thus determines the status of the ports and updates the status register, which is queried by the host.
