A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving interactions between various components within a wireless device to enable improved communications between wireless devices. In an example, a wireless device may include an application processor equipped to send first and second amounts of data to be buffered in a buffer associated with a controller, and cease communications with the controller after the second amount of data is sent. In an aspect, the ceasing of communications may include switching to a sleep mode. In an aspect, the amounts of data are larger than a threshold data size, and the buffer includes logically combined dedicated memories from SOCs for a plurality of access technologies controlled by the controller.
