摘要： A method includes obtaining a transmission to be transmitted via a transmission channel. The method also includes identifying at least one symbol included in the transmission. The at least one symbol may include multiple tones. The method further includes performing a first modulation to a first subset of the multiple tones. The method also includes performing a second modulation to a second subset of the multiple tones.

摘要： A method to operate a wireless access point (WAP) that includes identifying multiple stations from uplink statistics of a plurality of uplinks and determining an optimal spatial state of an antenna array for reception of the plurality of uplinks. Channel state information (CSI) is evaluated for each antenna in the antenna array. Determining the optimal spatial state of the antenna array includes using the CSI for each antenna to extrapolate the optimal spatial state of the antenna array for the plurality of uplinks. The method further includes changing a spatial state of the antenna array to the optimal spatial state.

摘要： A communication system includes multiple distributed antenna circuits and an access point (AP). The distributed antenna circuits include at least first and second antenna circuits. The AP is coupled to the distributed antenna circuits and includes multiple transmit chains, multiple receive chains, and an antenna control circuit communicatively coupled to the transmit chains and the receive chains. The first antenna circuit is co-located with the AP and the second antenna circuit is remote from the AP. The antenna control circuit is configured to determine a subset of the distributed antenna circuits to communicatively couple to at least some of the transmit chains to transmit data to a wireless station (STA) that is in range of the subset.

摘要： A method includes sending wireless data to a receiver node and receiving feedback from the receiver node that identifies a subset of the wireless data that the receiver node failed to receive correctly and that includes a token value as a label for the subset of the wireless data as a group. The method includes constructing retransmission wireless data that includes the subset of the wireless data and the token value. The method includes sending the retransmission wireless data to the receiver node. The receiver node may be a first client device. The method further includes allocating a first set of token values to the first client device and a second set of non-overlapping token values to a second client device in a network. The method includes respectively notifying the first and second client device of the corresponding set of token values for retransmissions requested by the corresponding client device.

摘要： This disclosure describes a system for applying precise timing to a mesh wireless Wi-Fi network. The precise timing allows for multiple access points (APs) to serve a single station (STA) when the STA is located in a wireless footprint of more than one access point without the need for a wireless trigger frame. Various examples are described including the use of orthogonal frequency division multiple access (OFDMA), time division multiple access (TDMA) and multi-access point joint transmission.

摘要： Example operations may include initiating wireless transmission of a first data frame of data designated for wireless transmission. The wireless transmission of the first data frame may be via a first wireless signal packet configured to carry the data of the first data frame. The operations include directing termination of the wireless transmission of the first data frame via the first wireless signal packet prior to wireless transmission, via the first wireless signal packet, of all of the data of the first data frame. In addition, the operations include directing, in response to termination of transmission of the first data frame, wireless transmission of a termination signal, the termination signal indicating that transmission of the first data frame via the first wireless signal packet terminated prior to completion of transmission of all of the data of the first data frame via the first wireless signal packet.

摘要： Methods and systems may include processes that may implement abbreviated header communications. In some implementations, a method may include generating a packet including an abbreviated header, where the abbreviated header may include a pointer corresponding to values for multiple parameters associated with a physical layer of communication rather than the values for the multiple parameters. The method may also include transmitting the packet to a client device according to the values for the multiple parameters.

摘要： 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.

摘要： 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.
