    • A method for operating an ultra-wideband radio communication device is provided. The method provided includes generating a channel changing negotiating message including information about at least one frequency channel the ultra-wideband radio communication device intends to change to. The method provided further includes transmitting the channel changing negotiating message to at least one other ultra-wideband radio communication device with which the ultra-wideband radio communication device has an established communication connection in a current frequency channel. According to the method provided, the ultra-wideband radio communication device may receive channel changing negotiating messages from the at least one other ultra-wideband radio communication device, where the channel changing negotiating messages include information about at least one frequency channel the other ultra-wideband radio communication device intends to change to. The ultra-wideband radio communication device may determine whether the ultra-wideband radio communication device is able to change to the at least one frequency channel included in the channel changing negotiating message, and may generate a further channel changing negotiating message including information about at least one frequency channel the ultra-wideband radio communication device intends to change to. The ultra-wideband radio communication device may then transmit the further channel changing negotiating message to the other ultra-wideband radio communication device. After a predetermined interval, the ultra-wideband radio communication device may select, based on a predetermined criterion, the frequency channel to change to, if the ultra-wideband radio communication device is the initiator of the intended change of frequency channel.
    • 提供了一种用于操作超宽带无线电通信设备的方法。 提供的方法包括生成信道改变协商消息,其包括关于超宽带无线电通信设备想要改变的至少一个频率信道的信息。 所提供的方法还包括:将信道改变协商消息发送到至少一个超宽带无线电通信设备,超宽带无线电通信设备在当前频道中具有建立的通信连接。 根据所提供的方法,超宽带无线电通信设备可以从至少一个其他超宽带无线电通信设备接收信道改变协商消息,其中信道改变协商消息包括关于至少一个频率信道的信息, 宽带无线电通信设备有意改变。 超宽带无线电通信设备可以确定超宽带无线电通信设备是否能够改变到信道改变协商消息中包括的至少一个频率信道,并且可以生成另外的信道改变协商消息,其包括关于至少 超宽带无线电通信设备想要改变的一个频道。 然后,超宽带无线电通信设备可以向另一个超宽带无线电通信设备发送另外的信道改变协商消息。 在预定间隔之后,超宽带无线电通信设备可以基于预定准则来选择频域以改变,如果超宽带无线电通信设备是频道预期改变的发起者。

    • A method of determining a first carrier frequency offset between a transmitter and a receiver for a first frequency band and a second carrier frequency offset between the transmitter and the receiver for a second frequency band is provided. The method provided includes determining an estimate of the first carrier frequency offset, determining an estimate of the second carrier frequency offset, determining an estimate of a first sampling interval offset between the transmitter and the receiver for the first frequency band based on the determined estimate of the first carrier frequency offset, and determining an estimate of a second sampling interval offset between the transmitter and the receiver for the second frequency band based on the determined estimate of the second carrier frequency offset. The method provided further includes determining an averaged sampling interval offset based on the calculation of an average of the determined estimate of the first sampling interval offset and the determined estimate of the second sampling interval offset, and determining the first carrier frequency offset and the second carrier frequency offset based on the determined averaged sampling interval offset.
