Abstract: In certain aspects, an apparatus includes a processing system configured to generate a first frame, wherein the first frame includes one or more parameters for a first time slot. The apparatus also includes an interface configured to output the first frame for transmission, and to obtain first data from a wireless node within the first time slot or output first data for transmission to the wireless node within the first time slot.

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 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: 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.
