  • Patent number: 11889532
    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.

  • Patent number: 11882589
    Abstract: 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.

  • Patent number: 11882557
    Abstract: A method to adaptively select uplink (UL) duration includes collecting UL transmission statistics for UL transmissions from multiple client stations to an access point (AP). The method includes estimating, based on the UL transmission statistics, an amount of queued UL data at the client stations for a next UL transmission. The method includes determining, based on the estimated amount of queued UL data and the UL transmission statistics, one or more UL durations for the next UL transmission. The method includes sending the client stations scheduling information with the determined one or more UL durations to initiate the next UL transmission from the client stations to the AP.

  • Patent number: 11876584
    Abstract: 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.

  • Publication number: 20230299889
    Abstract: 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.

  • Patent number: 11758461
    Abstract: 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.

  • Publication number: 20230120992
    Abstract: A method may include determining, by an access point, which stations among multiple stations are permitted access to a wireless communication medium in a subsequent uplink frame. The method may also include broadcasting an uplink map to the stations, where the uplink map identifies a first station of the multiple stations as permitted access to the wireless communication medium. The uplink map may also identify an allocation of the subsequent uplink frame for the first station. The method may also include, during the allocation of the subsequent uplink frame allocated to the first station, receiving: an acknowledgment (ACK) of downlink data transmitted to the first station, uplink data, a resource allocation request from the first station requesting access to a second subsequent uplink frame, and/or combinations thereof.
