Abstract
Systems and methods are provided for transmitting low latency traffic in next generation wireless local area networks. A new Media Access Control (MAC) layer frame can be transmitted by an AP to establish a reserved time period during which interference from/collisions with other stations transmitting non-high priority data is avoided. Stations with non-high priority data queued for transmission can defer accessing a channel on which to effectuate the transmission until the reserved time period expires.
Claims20
A device, comprising:
- a processor;
- and
- a memory operatively connected to the processor, and including computer code that when executed, causes the processor to:
- transmit a high priority epoch (HPE) Media Access Control (MAC) layer control frame comprising a duration field setting forth a reserved period on a channel for high priority traffic transmission;
- enable, via the transmitted HPE frame, high priority traffic to be transmitted from one or more stations on the channel during the reserved period;
- and
- enable, via the transmitted HPE frame, non-high priority traffic to be transmitted from the one or more stations on the channel only after the reserved period expires or is terminated.
A device, comprising:
- a processor;
- and
- a memory operatively connected to the processor, and including computer code that when executed, causes the processor to:
- wake after exiting a power-save mode;
- transmit one of a polling frame or null frame to an associated access point;
- in response, receive a high priority epoch (HPE) Media Access Control (MAC) layer control frame comprising a duration field setting forth a reserved period on a channel during which only high priority data may be transmitted;
- and
- defer transmission of queued non-high priority data or attempt channel access for transmission of queued high priority data on the channel.
An access point, comprising:
- a processor;
- and
- a memory operatively connected to the processor, and including computer code that when executed, causes the processor to:
- receive a first high priority epoch (HPE) Media Access Control (MAC) layer control frame from another access point;
- determine whether a request-to-send and clear-to-send (RTS/CTS) transmission mechanism is utilized for data transmission by the stations;
- and
- transmit a second HPE MAC layer control frame comprising a duration field that is receivable by the stations, the duration field enabling establishment of a reserved time period during which only high priority data from the stations can be transmitted.
