Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for encoding data for wireless transmissions. In one aspect, a wireless device may encode a number (M) of systematic bits for transmission to a receiving device. The systematic bits may be encoded using a low-density parity-check (LDPC) code to produce an LDPC codeword. The LDPC codeword may include a number (N) of codeword bits, including the M systematic bits and one or more parity bits. The wireless device may further puncture a number (K) of the codeword bits to produce a punctured codeword having a code rate M/(N−K)>5/6. The wireless device may transmit the N−K remaining codeword bits, over a wireless channel, to a receiving device.

Abstract: This disclosure provides methods, devices, and systems for a wireless communication device to perform signal phase rotation. In some implementations, the wireless communication device may determine a number of phase rotation parameters to be applied to a number of tones of a transmission signal. In some aspects, each of the phase rotation parameters indicates a phase rotation to be applied to each of the tones according to a carrier index range for each of the tones and a bandwidth mode for the transmission signal. In some implementations, the wireless communication device may apply the phase rotation parameters to respective ones of the tones according to the specified phase rotations and the carrier index ranges, and transmit the transmission signal from the wireless communication device according to the applied phase rotation parameters.

Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for signaling communication characteristics between wireless devices. In one implementation, a first wireless communication device may determine that a trigger frame will allocate one or more resource units for communications by one or more stations unassociated with the first wireless communication device. The first wireless communication device adds an indication of a reference channel associated with the first wireless communication device or a basic service set (BSS) color indication to the trigger frame. The trigger frame is output for transmission to one or more other wireless communication devices. A receiving device may then identify the reference channel or the BSS color indication from the trigger frame and use this information for communication with the first wireless communication device.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for techniques for 4096 Quadrature Amplitude Modulation (4096-QAM) with Uniform Constellations and Non-uniform Constellations and 16384 Quadrature Amplitude Modulation (16384-QAM) with Uniform Constellations and Non-uniform Constellations in Wireless Local Area Networks (WLAN). These 4096-QAM and 16384-QAM techniques can be implemented in a QAM modulator circuit on the transmit side and in a QAM demodulator circuit on the receive side to increase peak data rate without the need for additional transmission power or bandwidth.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sub-channel selection in a wireless network. In one aspect, a first message is generated at a first electronic device of a wireless network in response to a number of electronic devices of a wireless network being less than a threshold number. The first message indicates particular sub-channels of a transmission band that are to be used for a transmission in a single user (SU) mode of operation to a second electronic device of the wireless network. The method further includes sending the first message to the second electronic device. The first message indicates that a second message is to be sent to the second electronic device using the particular sub-channels. The method further includes sending the second message to the second electronic device via the transmission using the particular sub-channels.

Abstract: Techniques and apparatus for wake-up radio (WUR) operations are provided. One technique includes communicating with one or more wireless devices via a first radio operating on a first channel. A WUR is operated on a second channel different from the first channel.

Abstract: A method and an apparatus for wireless communication are provided. In one configuration, an apparatus is configured to transmit a wake-up radio (WUR) signal, to determine to transmit a second signal within a SIFS after transmitting the WUR signal to increase medium reuse, and to transmit the second signal within the SIFS after transmitting the WUR signal based on the determination. The second signal may be a data, management, control, ACK, or CF-end frame to enable legacy devices that do not decode the WUR signal to avoid wasted airtime cause by EIFS after the WUR signal. In another configuration, the apparatus is configured to transmit a CTS-to-self frame, to determine to transmit a second signal within a SIFS after transmitting the CTS-to-self frame, and to transmit the second signal based on the determination. The second signal may be a WUR signal or an intermediate signal followed by a WUR signal.
