Abstract
A method for confirming receipt of an aggregated data frame containing one or more decoding errors is disclosed. A wireless device receives the aggregated data frame from another device over a wireless channel, determines a transmit duration of the aggregated data frame, and defers access to the channel for a time period selected as either an EIFS duration or a DIFS duration based, at least in part, on the transmit duration, and then transmits a block acknowledgement frame to the other device after the time period.
Claims28
A method, performed by a wireless device, for confirming receipt of aggregated data containing one or more decoding errors, the method comprising:
- determining a transmit duration of an aggregated data frame received from another device over a wireless channel;
- and
- deferring access to the channel for a time period selected as either an extended interframe space (EIFS) duration or a distributed coordination function (DCF) interframe space (DIFS) duration based, at least in part, on the transmit duration.
A wireless device for confirming receipt of aggregated data containing one or more decoding errors, the wireless device comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the wireless device to:
- determine a transmit duration of an aggregated data frame received from another device over a wireless channel;
- and
- defer access to the channel for a time period selected as either an extended interframe space (EIFS) duration or a distributed coordination function (DCF) interframe space (DIFS) duration based, at least in part, on the transmit duration.
A non-transitory computer-readable medium containing program instructions that, when executed by a processor of a wireless device, causes the wireless device to perform operations comprising:
- determining a transmit duration of an aggregated data frame received from another device over a wireless channel, the aggregated data frame containing one or more decoding errors;
- and
- deferring access to the channel for a time period selected as either an extended interframe space (EIFS) duration or a distributed coordination function (DCF) interframe space (DIFS) duration based, at least in part, on the transmit duration.
A wireless device to confirm receipt of aggregated data containing one or more decoding errors, the wireless device comprising:
- means for determining a transmit duration of an aggregated data frame received from another device over a wireless channel;
- and
- means for deferring access to the channel for a time period selected as either an extended interframe space (EIFS) duration or a distributed coordination function (DCF) interframe space (DIFS) duration based, at least in part, on the transmit duration.
