Abstract
Methods, systems, and devices for wireless communication are described. An access point (AP) transmits instructions to quiet a dynamic frequency selection (DFS) home channel for a period of time. Instructions can include a quiet information element (IE) or a clear-to-send to self (CTS2Self) frame. The AP then allocates a first dedicated RF chain to a first media access control (MAC) component and a second dedicated RF chain, separate from the first dedicated RF chain, to a second MAC component of the access point. The allocation can include reducing the number of RF chains dedicated to the first MAC component. During the time period determined by the instructions, the first dedicated RF chain scans the home DFS channel and the second dedicated RF chain scans at least one other channel (e.g., based at least in part on the time period and channel scan priority) in the same band as the DFS home channel.
