Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless communication with partial channel puncturing. Using partial channel puncturing, a wireless local area network (WLAN) device may modulate data on a first portion of a wireless channel while refraining from modulating data on a second portion of the wireless channel. The partial channel puncturing can be used with an exclusion bandwidth zone defined for the WLAN. The exclusion bandwidth zone prevents transmissions on portions of channels so that the WLAN transmissions do not interfere with an incumbent system transmission in the exclusion bandwidth zone.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for managing high volumes of space-time-streams in Wi-Fi systems. An access point (AP) may transmit packets including long training field (LTF) sections using a number of space-time-streams greater than eight. Mobile stations (STAs) in the system may or may not be capable of processing this number of streams. The AP may modulate an LTF section using a matrix with dimensions smaller than the number of streams by using tone-interleaving or by performing modulation with separate matrices in time and frequency. In some other implementations, the AP may split the antennas for transmission into groups, each group transmitting either different packets in a subset of streams or a same packet in a subset of tones. In further implementations, the AP may combine multiple space-time-streams into a super stream that supports reception at different types of STAs.

Abstract: One aspect includes a method of establishing, via a first access point, a distributed MIMO joint transmission opportunity with one or more second access points to one or more stations. The method comprises generating, via a processor, a first message for transmission to the stations and the second access points. The first message indicates a null data packet transmission and the stations configured to receive a stream during the joint transmission opportunity. The method also comprises transmitting the first message to the second access points and the stations. The method further comprises generating, via the processor, a reference phase signal for transmission to the second access points.

Abstract: Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may generate an indication that a first channel of a plurality of channels associated with a transmission frame has been punctured, the transmission frame including a WLAN signaling field. The transmitter may identify information associated with the WLAN signaling field corresponding to the punctured first channel. The transmitter may transmit the information associated with the WLAN signaling field in a second channel of the plurality of channels. The transmitter may transmit the indication that the first channel has been punctured in the second channel or in a second WLAN signaling field of the transmission frame.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus is configured to determine a power control command including a target receiver power level for uplink transmission. The apparatus is configured to transmit a frame to a wireless device. The frame may include information associated with the determined target receiver power level for uplink transmission from the wireless device and a transmit power level at which the frame is to be transmitted. The information may enable the wireless device to compute a transmit power for the uplink transmission. The frame may include power control commands for other wireless devices.

Abstract: This disclosure provides systems, methods and apparatuses for determining input power backoff (IBO) settings used to transmit wireless signals. In some implementations, a first wireless device may negotiate a mutually compatible set of IBO settings with a second wireless device, may receive a wireless signal from the second wireless device, and may determine the actual IBO value used by the second wireless device to transmit the wireless signal based at least in part on the negotiated set of IBO settings. The first wireless device may also receive an indication of the changed set of IBO settings from the second wireless device, and may update the set of IBO settings stored in the first wireless device based on the received indication.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.

Abstract: Techniques are described herein that illustrate a feedback system to configure various format parameters of physical layer convergence procedure protocol data units (PPDUs) transmitted across a communication link. A receiving device may determine a Doppler shift or a delay spread of a signal received from a transmitting device. The receiving device may determine one or more format parameters for a future PPDU based on the Doppler shift or the delay spread. The receiving device may transmit an indication that includes the format parameters for the future PPDU to the transmitting device. The transmitting device may modify one or more format parameters of a PPDU based on the information in the indication. In some cases, the receiving device may indicate characteristics of mid-ambles, a type of PPDU, a guard interval, high efficiency long training field size for a future PPDU.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for generating wake-up radio (WUR) frames formats and implementing WUR communications between transmitting and receiving wireless devices. A transmitting wireless device may identify one or more intended receiving wireless devices for which to send a WUR frame. The transmitting wireless device may generate the WUR frame, where the WUR frame has a first portion that includes a first field. The first field may indicate whether the WUR frame is a fixed length frame or a variable length frame. The transmitting wireless device may also determine a frame check sequence (FCS) type for use with a WUR frame for transmission. The FCS portion may be capable of being one of a plurality of FCS types. The transmitting wireless device may transmit the WUR frame to the one or more intended receiving wireless devices.
