1. An apparatus for wireless communication at an access device, comprising:
a first interface configured to:
connect with an access network entity via a cellular modem associated with the access device;
the first interface or a second interface configured to:
obtain, from the cellular modem associated with the access device, one or more communication parameters associated with a connection state of the cellular modem with the access network entity, wherein the connection state comprises a radio resource control (RRC) state of the cellular modem;
a processing system configured to:
select a power mode for a wireless local area network (WLAN) access point (AP) associated with the access device in accordance with the one or more communication parameters associated with the connection state of the cellular modem, wherein selecting the power mode for the WLAN AP comprises:
allowing a sleep mode for one or more stations (STAs) served by the access device via the WLAN AP and the access network entity via the cellular modem based at least in part on the RRC state of the cellular modem comprising a RRC idle state;
allowing or rejecting the sleep mode for the one or more STAs based at least in part on the RRC state of the cellular modem comprising a RRC inactive state; or
rejecting the sleep mode for the one or more STAs based at least in part on the RRC state of the cellular modem comprising a RRC connected state; and
the second interface configured to:
communicate with the one or more STAs served by the access device via the WLAN AP and the access network entity via the cellular modem in accordance with the connection state of the cellular modem and the power mode for the WLAN AP.
