Definitions

• Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power).
• a wireless network for example a WLAN, such as a Wi-Fi (i.e., IEEE 802.11) network may include an access point (AP) that may communicate with one or more stations (STAs) or mobile devices.
• the AP may be coupled to a network, such as the Internet, and may enable a STA to communicate via the network (or communicate with other devices coupled to the AP).
• the apparatus may include a processor, memory in electronic communication with the processor, and
• FIG. 8 illustrates a block diagram of a system including an AP that supports improving uplink airtime fairness through basic service set steering in accordance with aspects of the present disclosure.
• FIG. 9 illustrates methods for improving uplink airtime fairness through basic service set steering in accordance with aspects of the present disclosure.
• the dynamically created BSSs 315 may include throttling parameters that are different from the parameters associated with the persistent BSSs 310.
• BSS 305-b may be configured with larger Enhanced Distributed Channel Access (EDCA) deferrals or shorter Transmission Opportunities (TXOPs) compared to BSS 305-a.
• BSS 305-b may also be configured to selectively withhold a clear to send (CTS) message for the STA, drop an uplink packet received from a STA, or modify an uplink Aggregate MAC Protocol Data Unit (A-MPDU) policy for the STA.
• CTS clear to send
• A-MPDU uplink Aggregate MAC Protocol Data Unit
• BSS 305-d may be configured with larger EDCA deferrals or shorter TXOPs compared to BSS 305-c.
• BSS 305-d may also be configured to selectively withhold a CTS message for the STA, drop an uplink packet received from a STA, or modify an uplink A-MP
• the AP 105-b may determine that the STA 115-c is monopolizing a channel of the first BSS. In some examples, the AP 105-b may determine that the STA 1 15-c is monopolizing a channel of the first BSS by determining a performance degradation of another device connected to the AP 105-b at block 415. In other examples, the AP 105-b may determine that the airtime usage of the STA 115-c at block 420. For example, the AP 105-b may determine that the STA 1 15-c is utilizing more than a fair share of airtime compared to other devices connected to the AP 105-b.
• the second BSS may also be created to selectively withhold CTS messages, drop uplink packets, or have a modified A-MPDU policy.
• the AP 105-b may select a duration field value for a CTS message for the first client device based on the determination at block 410, the selected duration field value may be less than a requested duration value of an RTS message from the first client device.
