This disclosure provides methods, components, devices, and systems for sounding for trigger-based ranging. Some aspects more specifically relate to a first wireless device dividing a frequency bandwidth available for ranging procedures into a plurality of subbands in accordance with orthogonal frequency-division multiple access (OFDMA) techniques. In some implementations, the first wireless device may transmit a trigger frame that assigns a subband to a respective neighbor wireless device. Each respective neighbor wireless device may transmit, during a same time occasion, a respective sounding signal via each respective subband allocated to the respective neighbor wireless device. In some implementations, the first wireless device may perform sounding procedures using combined multiple input multiple output (MIMO) and OFDMA techniques, where each neighbor wireless device may be assigned a respective spatial stream. Accordingly, the first wireless device may support sounding procedures for larger quantities of neighbor wireless devices.

Sounding for trigger-based ranging

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station. The AP may communicate with the station based on the modified uplink communication scheme.

Uplink flow control

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.
