“…In addition, [11] proposed a multi-service system based on the filter-bank multicarrier (FBMC) waveform that may provide a better OoBE and isolation between service bands. However, as also pointed out in literature [3] [4] [10] [12], FBMC system is significantly more complex than OFDM-based system. Nevertheless, the proposed interference cancelation schemes are generic and can be combined with other systems such as FC-OFDM and FBMC proposed in [10] and [11], respectively.…”

“…However, alternative advanced MC waveforms (e.g., filter bank MC (FBMC) and universal filtered MC (UFMC) [4]) can also be considered since such waveforms can localize the interference, which can be essential to flexibly support different use cases, topologies, communication links, and so on. Furthermore, single carrier (SC) waveform is also a promising candidate to provide good coverage even when extremely wider bandwidth transmissions (e.g., > 1 GHz) are introduced in higher frequency bands such as above 30 GHz.…”

SUMMARY Currently, many operators worldwide are deploying Long Term Evolution (LTE) to provide much faster access with lower latency and higher efficiency than its predecessors 3G and 3.5G. Meanwhile, the service rollout of LTE-Advanced, which is an evolution of LTE and a "true 4G" mobile broadband, is being underway to further enhance LTE performance. However, the anticipated challenges of the next decade (2020s) are so tremendous and diverse that there is a vastly increased need for a new generation mobile communications system with even further enhanced capabilities and new functionalities, namely a fifth generation (5G) system. Envisioning the development of a 5G system by 2020, at DOCOMO we started studies on future radio access as early as 2010, just after the launch of LTE service. The aim at that time was to anticipate the future user needs and the requirements of 10 years later (2020s) in order to identify the right concept and radio access technologies for the next generation system. The identified 5G concept consists of an efficient integration of existing spectrum bands for current cellular mobile and future new spectrum bands including higher frequency bands, e.g., millimeter wave, with a set of spectrum specific and spectrum agnostic technologies. Since a few years ago, we have been conducting several proof-of-concept activities and investigations on our 5G concept and its key technologies, including the development of a 5G real-time simulator, experimental trials of a wide range of frequency bands and technologies and channel measurements for higher frequency bands. In this paper, we introduce an overview of our views on the requirements, concept and promising technologies for 5G radio access, in addition to our ongoing activities for paving the way toward the realization of 5G by 2020.

One of evaluation indicators of candidate waveforms for 5G mobile communication is spectral efficiency improvement by OOB(Out of Band) power reduction technique. In this paper, time-frequency resource allocation characteristic of UFMC(Universal Filtered MultiCarrier), FBMC(Filter Bank Multi-Carrier), and W-OFDM(Weighted Orthogonal Frequency Division Multiplexing) system is evaluated and analyzed. As simulation results, spectral efficiency characteristic of these systems have been improved according to time resource allocation. In this paper, we can confirm that each system has similar time-frequency efficiency characteristic when the number of transmission bit is same and four symbols are transmitted with the linear system condition. Also, we can conclude that FBMC system has the lowest time-frequency resource efficiency under the nonlinear condition.
