Abstract: 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.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device, such as a device in a wireless local area network, may use a radio frame structure that includes a high efficiency (HE) signal field and an HE data field for communications, for example, over shared radio frequency spectrum. One or more bits or symbols within the HE signal field may be adjusted to avoid a high peak-to-average power ratio (PAPR). In some cases, the adjustment may be to a signal A (SIG-A) or signal B (SIG-B) field. In some examples, a random bit sequence may be used for padding in a signal field. In other examples, bits may be reversed or scrambled. In yet other examples, bits may be modulated and a phase rotation may be applied to the corresponding signal.

Abstract: A method and apparatus for tracking amplitude and phase of a received low frequency signal comprising a walking pilot signal is disclosed, wherein the pilot signal changes in frequency a number of times according to a sequence that repeats. The design includes initializing a FIFO buffer and summing estimated channel power over the sequence to determine an initial total power. The design also includes, for a new received symbol, determining an updated power estimate for the new received symbol, placing the updated power estimate in the FIFO buffer, and removing a least current value from the FIFO buffer, and estimating amplitude of the signal using a sum of all updated power estimates in the FIFO buffer divided by the initial total power. The design may further include determining a delta phase value using maximum ratio combining scaled with a scaling factor.
