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 are described for wireless communication. A station (STA) with a host processor and a radio processor may communicate with a first access point (AP) in a first subnet. The STA may store network information for the first subnet in memory of the STA. The STA may identify a second access point and determine, by the radio processor without communication with the host processor, whether the second access point is in the first subnet or a second subnet. The determination may be based at least in part on the network information stored in memory.

Abstract: Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.

Abstract: Systems, methods, apparatus, and devices for wireless communication are described. A first method includes establishing a first wireless local area network (WLAN) interface between a WLAN chipset and an application processor (AP) subsystem, and establishing a second WLAN interface between the WLAN chipset and a modem subsystem. The second WLAN interface may include a data path between the WLAN chipset and the modem subsystem. The data path may bypass the AP subsystem. A second method includes establishing a WLAN interface between a WLAN chipset and AP subsystem, and dynamically managing WLAN connectivity through the WLAN interface using a modem subsystem.
