Scheduler to improve fairness and throughput for full-duplex WiFi communications

A method for scheduling full-duplex (FD) downlink (DL) transmissions from an access point (AP) to a plurality of stations (STAs) of a wireless basic service set (BSS), the method comprising:

• decoding, by a processor of the AP, uplink (UL) data received from a UL STA in the BSS;
• selecting, by the processor, a downlink (DL) STA of the plurality of STAs in the BSS from a queue of DL STAs, wherein, the selected DL STA is a first STA in the queue for which a FD DL transmission rate from the AP to the selected STA is greater than a threshold transmission rate while the AP is decoding the UL data from the UL STA;
• providing, by the processor, an amount of data to be transmitted as an FD transmission to the selected DL STA while the AP is decoding the data from the UL STA;
• providing, by the processor, a further amount of data to be transmitted to the DL STA as a half-duplex (HD) transmission;
• and
• increasing, by the processor, a value representing the amount to be transmitted to the DL STA by the further amount of data.

A non-transitory computer readable medium including program instructions that, when executed, are configured to cause a processor in an access point (AP) of a basic service set (BSS) to:

• decode uplink (UL) data received via the interface from a UL STA in the BSS;
• select a downlink (DL) STA from a plurality of STAs in the BSS from a queue of DL STAs, wherein, the selected DL STA is a first STA in the queue for which a FD DL transmission rate from the AP to the selected STA is greater than a threshold transmission rate while the AP is decoding the UL data from the UL STA;
• provide an amount of data to be transmitted as an FD transmission to the selected DL STA while the AP is decoding the data from the UL STA;
• decode an acknowledgement message (ACK) from the DL STA indicating successful transmission of the amount of data from the AP to the DL STA;
• and
• maintain a position of the DL STA in the queue while the amount of data successfully transmitted to the DL STA is less than a threshold amount of data.
