## Abstract

Embodiments presented in this disclosure relate to methods and apparatuses (such as Access Points (AP's), evolved NodeB's (eNB's), etc.) for use in aggregation, or integration, between a Wireless Wide Area Network (WWAN) and a Wireless Local Area Network (WLAN). In one embodiment, an eNB decides that an aggregation between the WWAN and the WLAN is to be performed for at least one bearer of one or more bearers associated with a specific UE. Next, the eNB identifies which one(s) of the at least one bearer of the specific UE that is/are to be aggregated between the WWAN and the WLAN. Also, the eNB schedules each one of the at least one bearer identified to be aggregated between the WWAN and the WLAN.
