A communication device for aggregating long term evolution (LTE) and wireless local area network (WLAN) comprises a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise transmitting a first message indicating support of LTE-WLAN aggregation to a base station (BS) via a LTE communication; receiving a configuration message configuring reception of at least one LTE packet transmitted via a WLAN and a WLAN configuration from the BS via the LTE communication; receiving the at least one LTE packet from the BS via the WLAN in response to the configuration message; and not showing an identification of the WLAN configured by the WLAN configuration on a display of the communication device.
