摘要： Methods and apparatuses for providing wireless messages according to various tone plans can include a system configured to generate a message according to a 2048-tone plan having 1960 data tones. The 2048-tone plan includes two identical 1024-tone plans each having 980 data tones. The system can further perform segment parsing to divide data into two data portions, each portion for transmission over one of two 80 MHz bandwidths, according to one of the two identical 1024-tone plans. The system can further perform low density parity check (LDPC) tone mapping separately on each of the two data portions. The system can further provide the message for transmission over a 160 MHz bandwidth including the two 80 MHz bandwidths.

摘要： Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.
