“…Machine-type DUEs are permitted to reuse the spectral resources of cellular users according to the scheme outlined in [19] for D2D communication operating in a network employing strict FFR. Hence, DUEs in the inner region of a cell may reuse the spectral resources assigned to CUEs in the outer regions of neighbouring cells 1 . DUEs in the outer region of a cell may use any spectral resource, except the set assigned to CUEs in the same region.…”

“…5G could potentially be the first generation to permit the use of different waveforms for different use cases, each one optimal for a given scenario [1]. In this paper, we explore this possibility and focus on the coexistence between two 5G use cases, broadband services and machine-type device-todevice communications, which may use different waveforms.…”

Abstract-In this paper, we explore the idea that 5G will permit the use of multiple waveforms, with each service employing a waveform that is best suited for it. We look at a 5G machinetype communication (MTC) scenario consisting of clustered user equipment employing device-to-device (D2D) communication, such as a smart factory with inter-communicating machinery. The overhead associated with synchronising a large number of machine-type D2D user equipment (DUE) comes at a cost that may render synchronous communication infeasible or undesirable. Based on this motivation, we consider multiple possible combinations of prominent 5G waveform candidates for cellular users and DUEs, examining the asynchronous performance of all waveforms under consideration and using the performance of synchronous OFDM as a baseline for comparison. Specifically, we focus on the coexistence of waveforms in which the ordinary cellular users employ OFDM for synchronous communication, as in LTE, and the machine-type DUEs, operating asynchronously, employ a different waveform. When DUEs employ FBMC/OQAM, the average achieved rate is marginally greater than the synchronous OFDM baseline case, and approximately 43% greater than the asynchronous OFDM case. This result is encouraging, as the benefits of asynchronous D2D communication could be enjoyed in MTC scenarios without suffering any performance reduction compared to the synchronous OFDM scenario. We then investigate how the relative performance of different waveform choices depends on the scenario by varying key parameters. Notably, for asynchronous communication, increasing the transmit power of DUEs results in diminishing benefits unless the DUEs employ a waveform that mitigates inter-device leakage interference.

“…Bands at these frequencies have not previously been considered for cellular access, due to rain attenuation, atmospheric absorption, and huge propagation losses compared to lower carrier frequencies. In general, several technological challenges have still to be addressed before mm‐wave technology can be fully integrated in 5G networks; despite this, mm‐wave is seen as a promising technology with applications in indoor environments and backhauling of small cells …”

“…The GAA users are allocated spectrum resources with no interference protection guarantees and require active management to ensure that they do not interfere with either tier one or two users. The band foreseen for CBRS deployment is the 3.5‐GHz band in the USA . For the emerging applications in 5G networks and the spectrum sharing opportunities available through LSA and CBRS, novel spectrum allocation techniques need to be developed, due to the specific characteristics of said spectrum sharing regimes.…”

Spectrum sharing is one of the promising solutions to meet the spectrum demand in fifth‐generation networks that results from the emerging services like machine‐to‐machine and vehicle‐to‐infrastructure communication. The idea is to allow a set of entities to access the spectrum whenever and wherever it is unused by the licensed users. In the proposed framework, different spectrum provider (SP) networks with surplus spectrum available may rank the operators requiring the spectrum, called spectrum users (SUs) hereafter, differently in terms of their preference to lease spectrum, based, for example, on target business market considerations of the SUs. Similarly, SUs rank SPs depending on a number of criteria, for example, based on coverage and availability in a service area. Ideally, both SPs and SUs prefer to provide/get spectrum to/from the operator of their first choice, but this is not necessarily always possible due to conflicting preferences. We apply matching theory algorithms with the aim to resolve the conflicting preferences of the SPs and SUs and quantify the effect of the proposed matching theory approach on establishing preferred (spectrum) provider‐user network pairs. We discuss both one‐to‐one and many‐to‐one spectrum sharing scenarios and evaluate the performance using Monte Carlo simulations. The results show that comprehensive gains in terms of preferred matching of the provider‐user network pairs can be achieved by applying matching theory for spectrum sharing as compared with uncoordinated spectrum allocation of the available spectrum to the SUs.
