Abstract:
This disclosure describes methods, apparatus, and systems related to a conditional random access system. A device may identify a random access trigger frame on a communication channel, received from a first device, the trigger frame includes at least in part one or more random access resource units and one or more random access conditions. The device may measure a power level of the random access trigger frame. The device may determine a transmit power level associated with the device. The device may determine a received signal power level associated with the first device based at least in part on the one or more random access conditions.
Abstract:
This disclosure describes methods, apparatus, and systems related to non-contiguous channel bonding. A device may determine a wireless communication channel having one or more subchannels in accordance with one or more communication standards. The device may determine instructions to perform one or more clear channel assessments (CCAs) on at least one of the one or more subchannels. The device may cause to send the instructions to one or more first devices. The device may identify a frame received from at least one of the one or more first devices, wherein the frame is received on at least one available subchannel of the one or more subchannels.
Abstract:
A Trigger may be carried in a DL MU PPDU to solicit an UL BA. Then, the AP sends out the following transmission in SIFS time based on the UL BA information. There are numerous situations however where the AP should process the information transmitted (in UL) by multiple STAs and respond to them within the SIFS time. Some AP implementations (in particular the ones that do not use massive hardware (VLSI) accelerators) may not be able to finish the process within the SIFS time due to a very long PHY (Physical Layer) transmission decoding time (e.g., 802.11ax is 16 uS symbols vs 4 uS in legacy IEEE 802.11) and long PHY and MAC information possessing.
Abstract:
Some embodiments relate to a wireless network communications using Wireless Local Area Networks (WLAN). Some embodiments relate to high-efficiency wireless local-area networks (HEWs). Some embodiments relate to IEEE 802.11ax (and/or IEEE 802.11ac or IEEE 802.11ax+). Some embodiments relate to methods and devices for spatial reuse in any of these communications environments. Some embodiments relate to conditional reuse for Other Basic Service Set (OBSS) master stations and/or stations. Some embodiments relate to conditions that enable a HEW device to spatially reuse a portion of the wireless medium when the HEW device accurately determines a tolerable interference and either transmits an indication of the tolerable interference and/or lowers its own transmit power in accordance with the accurately determined tolerable or acceptable interference.
Abstract:
Some wireless communications environments, such as Wi-Fi, may include inexpensive power amplifiers where the power adjustment may not be accurate, and may also include pathloss measurement errors that are high enough to degrade performance of a power control algorithm. To address this issue, an exemplary aspect is directed toward a finite state power control algorithm and technique that, while designed for next generation Wi-Fi standards, such as 802.11ax, can in general be used with any wireless communication protocol or standard.
Abstract:
An exemplary aspect is directed toward methods, apparatus, and systems related to spatial reuse with overlapping basic service set. A device may determine an overlapping basic service set (OBSS) associated with one or more access points. The device may then reduce a transmit power by a first margin. The device may then increase a packet detection threshold associated with the OBSS by a second margin. The device then sends an uplink data frame to at least one of the one or more access points.
Abstract:
A method is provided by the present invention, comprises determining communication channel quality from a first wireless communications device to one or more other wireless communications devices, and assigning a zone/subband and corresponding power level to the one or more other wireless communications devices based on the communication channel quality. The method is directed toward at least addressing the interference from neighboring Access Points (APs), and reducing interference between devices using different power zones/subbands when the wide-band of Orthogonal Frequency-Division Multiple Access (OFDMA) based technologies were adopted in Wi-Fi systems for unlicensed bands.
