Abstract: An access point (AP) for wireless communication may include data processing hardware; and memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations including: identifying, at the AP, one or more transmitting stations having one or more spatial streams; sending, from the AP to the one or more transmitting stations, a sounding request; performing, at the AP, multiple user multiple input multiple output (MU-MIMO) channel estimation based on the sounding request response; computing, at the AP, one or more precoder coefficients for the one or more transmitting stations based on the MU-MIMO channel estimation; and sending, from the AP to the one or more transmitting stations, the one or more precoder coefficients and a transmission trigger.

Abstract: Methods and systems may include processes by which the reliability and robustness of a wireless network may be improved. In some implementations, a method may include selecting at least two resource units to be used for communications to a single client device; and transmitting data in duplicate via each of the at least two resource units to the client device such that the client device is able to combine the data from each of the at least two resource units into a single instance of the data. In some implementations, a method may include obtaining notification of one or more ranges of frequencies corresponding to a set of resource units to be avoided in a spectrum of available frequencies, and allocating resource units to a set of client devices that covers the available frequencies while excluding the set of resource units to be avoided.

Abstract: Technology disclosed herein may include an access point (AP) which may include a processing device. The processing device may transmit, at the access point, a first transmission in a first basic service set (BSS1) transmit opportunity (TXOP) in a first shared TXOP; send, from the access point to an additional access point, a first TXOP sharing request to send trigger frame; and receive, at the access point from the additional access point, a first clear to send (CTS) message.

Abstract: Technology disclosed herein may include an access point (AP) which may include a processing device. The processing device may determine, at the access point, an assigned time for the access point and a wireless device; receive, at the access point, a transmission opportunity (TXOP); identify, at the access point, scheduling information for the TXOP, wherein the TXOP is partitioned into a plurality of TXOP partitions comprising first TXOP partitions associated with the access point and second TXOP partitions associated with the wireless device; and provide, from the access point to the wireless device, scheduling information for the TXOP.

Abstract: Technology is disclosed for an access point (AP) including a processing device and a transceiver. The processing device may receive, at the AP from a station (STA), information about an interference path between the STA and the AP; select, at the AP, a transmit power based on the information about the interference path between the STA and the AP; and determine, at the AP, a transmission type based on the transmit power, wherein the transmission type comprise one or more of a spatial reuse transmission or a spatial nulling transmission. The transceiver may transmit, from the AP to the STA, a transmission based on the transmission type.

Abstract: An example method of wireless data transmission may include selecting a first frequency segment and selecting a second frequency segment that is different from and non-contiguous with the first frequency segment. The method may further include encoding a first signal with a data frame using the first frequency segment and encoding a second signal with the data frame using the second frequency segment. The method may further include providing the first signal and the second signal for wireless transmission such that at least a portion of the first signal and a portion of the second signal are simultaneously wirelessly transmitted.

Abstract: Example implementations are directed to methods and systems employing a solicited sounding protocol that includes receiving, by a second access point, a sounding trigger broadcast by a first access point. The methods and systems also include receiving, by the second access point, a dedicated training signal from a first station in response to the sounding trigger broadcast by the first access point, and generating, by the second access point, channel characteristics of a channel based on the first dedicated training signal, the channel including a forward channel between the second access point and the first station.

Abstract: An access point may include a processing device. The processing device may determine, at a medium access control (MAC) layer, a first modulation and coding scheme (MCS) for a first set of orthogonal frequency duplex multiplexing (OFDM) symbols. The processing device may determine, at the MAC layer, a second MCS for a second set of OFDM symbols. The processing device may generate, at the MAC layer, one or more aggregate MAC protocol data units (A-MPDUs) including the first MCS and the second MCS. The processing device may send, from the MAC layer to a physical layer (PHY), the one or more A-MPDUs to generate a PHY service data unit (PSDU) including the first MCS and the second MCS.
