Abstract: 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.

Additionally, or alternatively, the wireless communication device may use a first contention window size for a first quantity of transmission attempts and a second contention window size for a second quantity of transmission attempts.

In some examples, an AP may selectively enable or disable a power saving mode of the AP based on traffic characteristics associated with STAs communicating with the AP or one or more device characteristics associated with the STAs. The AP may then transmit an indication to the STAs of the power saving mode being enabled or disabled at the AP. In some other examples, the AP may monitor uplink transmissions from the STAs while in the power saving mode. The AP may then transmit an indication of a change in parameters of the power saving based on monitoring the uplink transmissions.
