Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, for generating or receiving a multi-generation physical layer protocol data unit (PPDU). The multi-generation PPDU may concurrently include a first generation-specific preamble based on a first generation of a wireless communication specification (such as that defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards) and a second generation-specific preamble based on a second generation of the wireless communication specification in a same transmission. The generation-specific preambles may be generated based on bandwidth portions of a wireless channel that each generation-specific preamble will occupy in the multi-generation PPDU. One or more of the generation-specific preambles may be modified based on an aggregate bandwidth of the multi-generation PPDU. This disclosure includes several options for modifying one or more generation-specific preambles or data fields to accommodate their use in a multi-generation PPDU.

Abstract: This disclosure provides methods, components, devices and systems for extended long range wireless packet design. Some aspects more specifically relate to increasing a data rate, a coverage range, or both for extended long range (ELR) wireless communications systems by updating an ELR wireless packet design. A wireless communications device, such as a wireless station (STA), may transmit an ELR wireless packet to another wireless communications device, such as a wireless access point (AP), with updated preamble fields, boosted transmit power for one or more preamble fields, and/or additional repetitions for one or more preamble fields. Additionally, or alternatively, the wireless communications device may transmit an ELR wireless packet using a narrow bandwidth to increase coverage range for an ELR wireless communications system.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. For example, a wireless communication device (WCD), may include multiple component chips configurable to work together as a partitioned chip having a capability to communicate using a quantity of spatial streams that exceeds a capacity of any one of the multiple component chips when operated independently. Some aspects more specifically relate to component chips having frequency domain components that support a first quantity of spatial streams in a frequency domain and having time domain components that support a second quantity of spatial streams in a time domain. In some examples, the first quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by multiple component chips, and the second quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by a single component chip.

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 pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.

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 physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for including signaling regarding enhanced features of new wireless communication protocols. The signaling may be included in various portions of a physical layer preamble of a wireless transmission. In some implementations, the physical layer preamble may be used to indicate puncturing of subbands or content channels that may carry further signaling in accordance with preamble signaling designs of this disclosure. The physical layer preamble signaling be parallelized for different subchannels of a wireless channel that consists of multiple subchannels. Some implementations of the physical layer preambles may be used to multiplex different types of wireless local area network communications into different subsets of the plurality of subchannels of the wireless channel.

Abstract: This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks. Some implementations more specifically relate to beamforming training operations that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a beamforming initiator may initiate a beamforming training operation by transmitting a number (N) of beamforming training (BFT) packets in N TX beam directions, respectively, on a carrier frequency above 7 GHz. The beamforming responder receives one or more of the BFT packets and provides feedback to the beamforming initiator indicating the TX beam direction associated with the BFT packet having the highest received signal power. In some aspects, the beamforming responder may train its RX antennas for RX beamforming concurrently while the beamforming initiator trains its TX antennas. In some other aspects, the beamforming responder may train its RX antennas after the beamforming initiator trains its TX antennas.

Abstract: A technique for wireless communication of a punctured null data packet with a long training field sequence is disclosed. The long training field (LTF) sequence is generated for the null data packet (NDP) for transmission over a channel having a bandwidth that is an integer multiple of 80 MHz. The LTF sequence is modulated onto a plurality of tones of the channel excluding tones within a punctured subchannel of a plurality of subchannels of the channel. The modulation may be based on a size and location of the punctured subchannel and a symbol duration associated with transmitting the LTF sequence. The NDP is transmitted including the LTF sequence to a second wireless communication device via the channel. A partial bandwidth feedback may be received in response to the LTF in the punctured NDP.

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 tone mapping techniques and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support duplicate (or “DUP mode”) transmissions with channel puncturing. In some implementations, a wireless communication device may transmit a PPDU carrying user data over a wireless channel excluding one or more punctured subchannels, where the user data is transmitted in a DUP mode. As such, the user data may be mapped to a number (N) of tones spanning a first portion of the wireless channel and a duplicate copy of the user data may be mapped to N tones spanning a second portion of the wireless channel.
