SECURE AND DISTRIBUTED DFS BETWEEN HOST AND FIRMWARE

Aspects of the disclosure provide techniques for a secure distributed dynamic frequency selection (DFS) scheme. In an aspect, the disclosure describes a method, device, and computer-readable medium in which DFS filtering is configured in each of a host software executable on a host processor and a firmware executable on a target processor on a single wireless communications device. The DFS filtering is initially (or by default) performed by the firmware. The firmware may then monitor a target load metric of the target processor to identify conditions that may indicate that the target processor is overloaded. Based on the monitoring, the firmware may determine whether to move the DFS filtering from being performed by the firmware to being performed by the host software (if deemed secure). The firmware may also move the DFS filtering back to being performed by the firmware if conditions at the target processor improve.
