SUMMARYMillimeter-wave (mm-wave) radio is attracting attention as one of the key enabling physical layer technologies for the fifthgeneration (5G) mobile access and backhaul. This paper aims at clarifying possible roles of mm-wave radio in the 5G development and performing a comprehensive literature survey on mm-wave radio channel modeling essential for the feasibility study. Emphasis in the literature survey is laid on grasping the typical behavior of mm-wave channels, identifying missing features in the presently available channel models for the design and evaluation of the mm-wave radio links within the 5G context, and exemplifying different channel modeling activities through analyses performed in the authors' group. As a key technological element of the mm-wave radios, reduced complexity beamforming is also addressed. Design criteria of the beamforming are developed based on the spatial multipath characteristics of measured indoor mm-wave channels.

“…As already established in [3], copolarized field power follows a Ricean distribution described by its K-factor, i.e., the ratio of the mean total received power to the mean scattered field power. The K-factor can be mapped to the outage probability for given data rates, modulation schemes, and transmitted power [4].…”

A quasi-deterministic model for the analysis of the electromagnetic propagation and estimation of main link parameters in fixed microwave and millimeter-wave links operating within urban or suburban environments is presented. The propagation geometry is modeled by a triangular mesh from the transformation of high-resolution LIDAR data. Subsequently, an efficient physical optics approximation is employed for the estimation of the mean scattered field power from surfaces within the main beams of the antennas. Random realizations of principal reflected and scattered fields constituents superimposed to the direct field allow for the prediction of worst-case link performance, in terms of outage probability, power delay spread, and cross-polar discrimination, for different design parameters: antenna position, gain, and height. The computations are compared to measurements of fixed links at 40 GHz.Index Terms-Directive antennas, electromagnetic (EM) modeling, microwave and millimeter-wave propagation, physical optics.

A Physical Optics approach to the analysis of the electromagnetic propagation and the estimation of main link parameters in LOS, point-to-point microwave links operating within urban environments is proposed and discussed. The propagation geometry is modeled by a triangular mesh obtained from the transformation of digital terrain (LIDAR) data. An asymptotic Physical Optics approximation is subsequently employed in the calculation of the scattered field power from surfaces within the main beamwidth of the two antennas. Random realizations of reflected and scattered field constituents are superimposed to the direct field and predict with reasonable accuracy link performance for main design variables, such as antenna position, gain and height. Direct and scattered field calculations are compared with measurements of fixed links of variable distance at 40GHz.Index Terms-electromagnetic modeling, microwave & millimeter wave propagation, microwave communications, physical optics, directive antennas.
