    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.

    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may direct stations (STAs) to use a request-to-send (RTS)/clear-to-send (CTS) mode so the AP may perform power savings and off-channel operations without disrupting the communications of nearby devices. In some cases, the AP may use traffic conditions to identify a power save period and subsequently transmit an indication of an RTS/CTS mode to multiple STAs. In one example, the AP may power down at least one radio frequency (RF) chain and enter into a sleep mode. Additionally or alternatively, during the power save period the AP may receive an RTS from a STA and power up additional radio chains for MIMO communication. In some cases, the AP may identify an off-channel operations period based on traffic conditions and perform the off-channel operations after indicating the RTS/CTS mode to a set of STAs.
