Npca misalignment and nav management

A wireless device comprising:

• a memory configured to store a network allocation vector (NAV);
• and
• processing circuitry that configures the wireless device to manage the NAV across a basic service set (BSS) primary channel and a non-primary channel access (NPCA) primary channel during NPCA operation by:
• maintaining intra-BSS NAV and inter-BSS NAV on the BSS primary channel;
• maintaining an NPCA NAV on the NPCA primary channel;
• setting NAV values from received frame duration information including a legacy duration field;
• and
• resetting the NPCA NAV upon return from the NPCA primary channel to the BSS primary channel.

A non-transitory computer-readable storage medium that stores instructions for execution by a processor of a wireless device, the instructions, when executed, cause the wireless device to:

• manage a network allocation vector (NAV) across a basic service set (BSS) primary channel and a non-primary channel access (NPCA) primary channel during NPCA operation by:
• maintaining intra-BSS NAV and inter-BSS NAV on the BSS primary channel;
• maintaining an NPCA NAV on the NPCA primary channel;
• setting NAV values from received frame duration information including a legacy duration field;
• and
• resetting the NPCA NAV upon return from the NPCA primary channel to the BSS primary channel.
