Scope
As the tremendous increase of the number of mobile users and the use of diverse wireless applications, the demands of wireless access to the Internet are also exponentially increased. As a consequence, not only the volumes of mobile data traffic overwhelm the capacity of existing wireless communication networks but the required high data rates also drain the limited radio resources. Theoretically, solution to this problem is to broaden the amount of allocated spectrum. However, spectrum for commercial use solely in the conventional licensed bands or ISM unlicensed bands is no longer enough to support the practical needs, which decreases the approachability of this solution and renders the interests of network operators. Hence, heterogeneous carrier communication technologies receive lots of attention from both industry and academy for data communications and telecommunications in recent years.
Heterogeneous carrier communication technologies enable the network to operate not only on homogeneous carriers. Instead, communications may be extended to carriers with different characteristics. For example, in licensed-assisted access (LAA) of LTE (also known as LTE-U), both licensed and unlicensed carriers are involved in, where licensed carriers are used for control channels, while unlicensed carriers are used for data channels. For IEEE 802.11 af, communications are no longer carrying out on ISM bands and are extended to TV bands. For IEEE 802.11 ac (also known as the fifth generation of WiFi), a higher order modulation (256-QAM), wider bandwidth (up to 160MHz), and 8X8 MIMO are adopted for indoor communications. Furthermore, communications using mmWave carriers recently also receive considerable attention due to the favor of wide available bandwidth. These innovative technologies although provide new communication paradigms enjoying wider bandwidth and/or stronger signal strength, they also suffer from unprecedented challenges.
