Abstract: Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.

Abstract: This disclosure provides methods, devices and systems for provisioning resources for wireless communications. Some implementations more specifically relate to provisioning such resources based on a mapping of wireless communication devices to a number of time sectors that occur periodically and do not overlap other time sectors. In some aspects, each wireless stations (STAs) in a basic service set (BSS) may be mapped to a respective time sector based on attributes associated with the BSS so that communications between a STA and its associated access point (AP) can only occur within the respective time sector(s) to which the STA is mapped. In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. For example, a wireless communication device (WCD), may include multiple component chips configurable to work together as a partitioned chip having a capability to communicate using a quantity of spatial streams that exceeds a capacity of any one of the multiple component chips when operated independently. Some aspects more specifically relate to component chips having frequency domain components that support a first quantity of spatial streams in a frequency domain and having time domain components that support a second quantity of spatial streams in a time domain. In some examples, the first quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by multiple component chips, and the second quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by a single component chip.

Abstract: Certain aspects of the present disclosure provide an architecture and method for multi-link operation (MLO) at an access point (AP). The method generally includes obtaining a packet from at least one buffer and selecting a processing path, from first and second processing paths, for a packet to be routed from the at least one buffer to at least one of a plurality of radio components for wireless transmission to at least one peer via one or more links, wherein: the first processing path is configured to bind the packet to one of the one or more links based on at least one code-implemented rule, and the second processing path is configured to bind the packet to one of the one or more links based on instantaneous channel sensing.

Abstract: An AP obtains service-level agreement (SLA) parameters indicating at least a delay bound for each of a plurality of traffic flows. The AP receives first packets of a first traffic flow, and delays their transmission for a delay period based on the data carried in the first packets being less than a first threshold. During the delay period, the AP receives second packets of the first traffic flow while also receiving packets of a second traffic flow, groups the second traffic flow with the first traffic flow for an MU-MIMO transmission based on the data carried in the first and second packets of the first traffic flow being greater than the first threshold and the data carried in the packets of the second traffic flow being greater than a second threshold, and transmits the first and second packets traffic flows as an MU-MIMO communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit an indication of a media access control (MAC) address associated with an access point to a group of access points included in a network. The network node may receive single-sided round-trip-time (RTT) data associated with a user device associated with the access point, wherein the single-sided RTT data is received from each of the group of access points based at least in part on transmitting the indication of the MAC address to the group of access points. The network node may determine a location of the user device based at least in part on the single-sided RTT data. The network node may transmit an indication of the location of the user device to the access point. Numerous other aspects are described.
