Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to using an external memory for both a wireless wide area network (WWAN) and a wireless local area network (WLAN) for WLAN power savings. An exemplary method includes obtaining messages (e.g., paging messages) via a receiver; reading, during a first wakeup period in which the apparatus is to monitor for messages in a first wireless local area network (WLAN) while the receiver is powered on, state information for the first WLAN from a shared memory also used to store state information for a wireless wide area network (WWAN), and using the state information to configure the apparatus for communicating in the first WLAN.

Abstract: Certain aspects of the present disclosure relate to switching data paths in a wireless device having first and second processors. The wireless device may determine a change to a service, the service using a first data path including a first internet protocol (IP) stack on the first processor and lower layer processing on a wireless modem, the first data path providing a tunneled connection to the service through a network. The wireless device may establish a second data path for the service, the second data path including a second IP stack on the second processor including tunneling to the service through the network and the lower layer processing on the wireless modem. The wireless device may switch the service from the first data path to the second data path in response to establishing the second data path. The first processor may be placed in a power save mode.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a network device. The apparatus receives an evolved multimedia broadcast multicast service (eMBMS) data from a base station via multicast transmission. The apparatus transmits the received eMBMS data to one or more end nodes via unicast transmission. In an aspect, the one or more end nodes are connected to the network device via a local area network (LAN).
