Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first wireless communication device associated with a basic service set (BSS) receives a plurality of packets transmitted during a measurement window by a second wireless communication device associated with the BSS. The first wireless communication device determines a received signal strength indicator (RSSI) value of the plurality of received packets, determines a level of overlapping basic service set (OBSS) interference on the wireless medium during the measurement window, and adjusts one or more of a packet detect (PD) threshold, an OBSS PD threshold, or an energy detect (ED) threshold based on the determined RSSI value and the level of OBSS interference.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems (e.g., Wi-Fi systems), a transmitting device such as an access point (AP) or mobile station (STA), may identify a number of spatial streams for a data transmission that is less than a number of transmit antennas, and may transmit a packet over a channel. In a first implementation, the packet may be formatted in a multi-user frame format, with a number of long training field (LTF) symbols equal to the number of transmit antennas. In a second implementation, the packet may be a null data packet (NDP), and the device may transmit a separate data packet. In a third implementation, the packet may be formatted in single-user frame format with a modified LTF. A receiving device may receive the packet, and may perform channel estimation and power amplifier (PA) distortion cancellation based on the received packet.

Abstract: Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA). The AP determines a communication metric associated with each of the plurality of MU-MIMO groups. The communication metric provides an indication of the compatibility of the STAs in the MU-MIMO group. The AP prioritizes at least one of the plurality of MU-MIMO groups based at least in part on the communication metric associated with the prioritized MU-MIMO group. The AP creates a preferred group list and/or a blacklisted group list and included the prioritized MU-MIMO group in the appropriate group list.

Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.
