    Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to LTF designs that support distributed transmissions. In some aspects, a transmitting device may obtain a sequence of values representing an LTF of a PPDU and may map the sequence of values to a number (N) of noncontiguous subcarrier indices of a plurality of subcarrier indices spanning a wireless channel according to a distributed tone plan. In some implementations, the transmitting device may modulate the sequence of values on N tones, representing a logical RU, and map the N tones to the N noncontiguous subcarrier indices, respectively. In some other implementations, the sequence of values may be obtained based on relative locations of the N noncontiguous subcarrier indices in the wireless channel.

    Abstract: This disclosure provides methods, devices and systems for improving wireless communications in power spectral density (PSD)-limited frequency bands. A wireless communication device, having a number (NTX) of transmit antennas, parses a physical layer (PHY) protocol data unit (PPDU) into a number (NSS) of spatial streams and modulates the NSS spatial streams on a number (M) of subcarriers. In some implementations, the wireless communication device may transmit the PPDU using a number (N) of the transmit antennas, where NSS≤N

    Abstract: This disclosure provides wireless communication methods, components, devices and systems for link recovery in wireless communication networks. Some aspects more specifically relate to the recovery of lost wireless communication links for which initial link establishment has been aided by communications over anchor links of different frequency bands than those of the lost wireless communication links. According to some aspects, a recovery mechanism can be implemented that enables involved devices to recover such “extension” links using communications over their associated frequency bands, without needing to revert to communication over their corresponding anchor links. In some examples, such a recovery mechanism can be implemented to enable recovery of a millimeter wave (mmWave) extension link of a non-standalone mmWave basic service set (BSS) without needing to revert to communication over a sub-7 GHz anchor link.

    Abstract: This disclosure provides methods, devices and systems for amplitude shaping encoding, and specifically, for indicating boundaries in bitstreams encoded using amplitude shaping encoding. In some aspects, a transmitting device may insert, into an bitstream to indicate a boundary, a sequence of amplitude bits not associated with any patterns of bit values in a lookup table used for the encoding. In some other aspects, a transmitting device may monitor a length of the amplitude bits in a bitstream during the encoding and stop the encoding on information bits at an end of a current data unit responsive to the length reaching a threshold. In some other aspects, a transmitting device may monitor the length of the information bits and, for each data unit, determine whether a boundary is or would be reached. Responsive to determining that a boundary is or would be reached, the transmitting device may not include, before the boundary, any amplitude bits generated based on the information bits in the data unit, and instead add padding bits after a last amplitude bit before the boundary.
