“…Similarly, a multidimensional waveform can be utilized for conveying both data and multidomain feature sensing. Due to the exponential increase in transceiver complexity, processing time and power consummation with the increase of the number of signal domains, the choice of the emitted signal becomes critical [67].…”

With the completion of the 5G standardization efforts, the wireless communication world has now turned to the road ahead, the future wireless communication visions. One common vision is that future networks will be flexible, or able to accommodate an even richer variety of services with stringent, often conflicting requirements. This ambitious feat can only be accomplished with a ubiquitous awareness of the radio and physical environment. To this end, this paper highlights the importance of wireless sensing as a means for radio environment awareness and surveys wireless sensing methods under different domains. Then, a review of wireless sensing from a standardization perspective is given.These standardization efforts will provide the initial landscape upon which research into future wireless sensing methods will be built upon. Therefore, the paper is concluded by outlining imperative standardization requirements and future directions in wireless sensing.

“…IM can be applied together with current technologies such as massive MIMO and can be used in high-mobility scenarios, such as mobile communications [5]. Spatial modulation (SM) and orthogonal frequency division multiplexing with IM (OFDM-IM) schemes are well-known examples of IM schemes [4,7].…”

“…On the other hand, the uplink has less complexity and can be addressed like an extension of GSM [23]. Some authors have proposed versions of IM based on multidimensional schemes, which are built with a combination of spatial and frequency domains [7]. In [24], the authors have merged both SM and OFDM-IM schemes simultaneously to produce a scheme named generalized space-frequency IM (GSFIM).…”

System-Level Assessment of a C-RAN based on Generalized Space–Frequency Index Modulation for 5G New Radio and Beyond

Index modulation (IM) has been attracting considerable research efforts in recent years as it is considered a promising technology that can enhance spectral and energy efficiency and help cope with the rising demand of mobile traffic in future wireless networks. In this paper, we propose a cloud radio access network (C-RAN) suitable for fifth-generation (5G) and beyond systems, where the base stations (BSs) and access points (APs) transmit multidimensional IM symbols, which we refer to as precoding-aided transmitter-side generalized space–frequency IM (PT-GSFIM). The adopted PT-GSFIM approach is an alternative multiuser multiple-input multiple-output (MU-MIMO) scheme that avoids multiuser interference (MUI) while exploiting the inherent diversity in frequency-selective channels. To validate the potential gains of the proposed PT-GSFIM-based C-RAN, a thorough system-level assessment is presented for three different three-dimensional scenarios taken from standardized 5G New Radio (5G NR), using two different numerologies and frequency ranges. Throughput performance results indicate that the 28 GHz band in spite of its higher bandwidth and higher achieved throughput presents lower spectral efficiency (SE). The 3.5 GHz band having lower bandwidth and lower achieved throughput attains higher SE. Overall, the results indicate that a C-RAN based on the proposed PT-GSFIM scheme clearly outperforms both generalized spatial modulation (GSM) and conventional MU-MIMO, exploiting its additional inherent frequency diversity.

“…On the other hand, MIMO techniques can be used to improve the system performance using diversity schemes, to increase the throughput using multiplexing schemes or to attain a combination of diversity, multiplexing and beamforming gains using the concept of multi-functional MIMO (Hanzo et al, 2011;Hemadeh et al, 2018). Additionally, the family of spatial modulation (SM) received significant research attention as detailed in (Ishikawa et al, 2018;Dogan-Tusha et al, 2020) for its reducedcomplexity processing at both the transmitter and the receiver.…”

Given the increasing demand for high data-rate, high-performance wireless communications services, the demand on the radio access networks (RAN) has been increasing significantly, where optical fiber has been widely used both for the backhaul and fronthaul. Additionally, advances in signal processing such as multiple-input multiple-output (MIMO) techniques, have improved the performance as well as transmission rate of communications networks. Beamforming has been used as an efficient MIMO technique for providing a signal to noise ratio (SNR) gain as well as reducing the multi-user interference. However, beamforming requires the employment of phase-shifters, which suffers from reduced phase resolutions, degraded noise figures as well as beam-squinting in addition to the implementation challenges. Hence, in this paper we employ an analogue radio over fiber (A-RoF) aided architecture for supporting the requirements of the current and future mobile networks, where we design a photonics aided beamforming technique in order to eliminate the bulky electronic phase-shifters and the beam-squinting effect, while also providing a low-cost RAN solution. Additionally, this photonics aided beamforming is combined with a reconfigurable multi-user MIMO technique, where users can communicate with one or multiple remote radio heads (RRHs), while employing stand-alone beamforming, beamforming combined with diversity or with multiplexing depending on the available resources and the user channel information as well as the quality of service requirements.
