Abstract
A method for communication includes accepting in an Access Point (AP) data items for transmission over a wireless channel to multiple terminals served by the AP. Aggregate airtimes, which were previously allocated to the respective terminals on the wireless channel, are assessed. Transmission of the data items is scheduled depending on the aggregate airtimes.
Claims23
A method for communication, comprising:
- accepting, in an Access Point (AP), downlink data items for transmission over a wireless downlink channel to multiple terminals served by the AP;
- assessing aggregate airtimes for the respective terminals, by summing, for each terminal, an aggregate downlink airtime that was previously allocated to the terminal on the wireless downlink channel and an aggregate uplink airtime that was previously used by the terminal on a wireless uplink channel from the terminal to the AP;
- and
- scheduling transmission of the downlink data items on the wireless downlink channel, depending one aggregate airtimes assessed for the terminals.
1 more element
A wireless Access Point (AP), comprising:
- a transmitter, which is configured to transmit downlink data items over a wireless downlink channel to multiple terminals served by the AP;
- and
- a processor, which is configured to assess aggregate airtimes for the respective terminals, by summing, for each terminal, an aggregate downlink airtime that was previously allocated to the terminal on the wireless downlink channel and an aggregate uplink airtime that was previously used by the terminal on a wireless uplink channel from the terminal to the AP, and to schedule transmission of the downlink data items on the wireless downlink channel depending on aggregate airtimes assessed for the terminals.
A system, comprising:
- multiple terminals;
- and
- an Access Point (AP), which is configured to transmit downlink data items over a wireless downlink channel to the terminals, to assess aggregate airtimes for the respective terminals, by summing, for each terminal, an aggregate downlink airtime that was previously allocated to the terminal on the wireless downlink channel and an aggregate uplink airtime that was previously used by the terminal on a wireless uplink channel from the terminal to the AP, and to schedule transmission of the downlink data items on the wireless downlink channel depending on aggregate airtimes assessed for the terminals.
