Abstract
A method is performed by a station (STA). The method includes the steps of receiving, from an access point (AP), an indication of whether to use a preamble detection NPCA channel switching approach or a control frame detection NPCA channel switching approach, overhearing a PPDU transmitted in a primary channel, and determining whether NPCA can be performed in a NPCA primary channel during transmission of the PPDU using the preamble detection NPCA channel switching approach or the control frame detection NPCA channel switching approach depending on the indication received from the AP.
Claims21
A method performed by a station (STA), the method comprising:
- receiving, from an access point (AP), an indication of whether to use a preamble detection NPCA channel switching approach or a control frame detection NPCA channel switching approach;
- overhearing a PPDU transmitted in a primary channel;
- and
- determining whether NPCA can be performed in a NPCA primary channel during transmission of the PPDU using the preamble detection NPCA channel switching approach or the control frame detection NPCA channel switching approach depending on the indication received from the AP.
A wireless device to function as a station (STA), the wireless device comprising:
- a radio frequency transceiver;
- a memory device storing a set of instructions;
- and
- a processor coupled to the memory device, wherein the set of instructions, when executed by the processor, causes the wireless device to:
- receive, from an access point (AP), an indication of whether to use a preamble detection NPCA channel switching approach or a control frame detection NPCA channel switching approach;
- overhear a PPDU transmitted in a primary channel;
- and
- determine whether NPCA can be performed in a NPCA primary channel during transmission of the PPDU using the preamble detection NPCA channel switching approach or the control frame detection NPCA channel switching approach depending on the indication received from the AP.
