Title: RECOVERY FOR 20 MHZ WIRELESS DEVICE OPERATING ON NON-PRIMARY 20 MHZ CHANNEL
Abstract:
Apparatuses, computer-readable media, and methods for recovery for 20 MHz wireless devices operating on a non-primary 20 MHz channel. An apparatus is disclosed, the apparatus comprising processing circuitry configure to: switch from a primary 20 MHz channel to a non-primary 20 MHz channel, and start a countdown of a timer. The processing circuitry further configured to when a trigger frame for uplink transmission is decoded from a HE access point and when the trigger frame comprises an indication of a uplink resource allocation for the HE station, reset the timer to an initial value. The processing circuitry further configured to when the timer reaches a final value, switch back to the primary 20 MHz channel.
