A3-1 Definition of d2D and d3D for outdoor UTs (left), definition of d2D-out, d2D-in, d3D-out, and d3D-in for indoor UTs (right) Note that: (3-1) In the Tables A3-1 to A3-4, the following applies – Note 1: fc in GHz denotes the center frequency normalized by 1 GHz, distance related values in meters are normalized by 1 m, unless it is stated otherwise. – Note 2: hUT and hBS are the antenna height at BS and UT, respectively. h and W are the average building height and average street – Note 3: For UMa_x, UMi_x, break point distance d'BP = 4 h'BS h'UT fc/c, where fc is the centre frequency in Hz, c = 3.0108 m/s is the propagation velocity in free space, and h'BS and h'UT are the effective antenna heights at the BS and the UT, respectively. The effective antenna heights h'BS and h'UT are computed as follows: h'BS = hBS – hE, h'UT = hUT – hE, where hBS and hUT are the actual antenna heights, and hE is the effective environment height. For UMi_x hE=1 m. For UMa_x hE=1m with a probability equal to 1/(1+C(d2D, hUT)) and chosen from a discrete uniform distribution uniform(12,15,…,(hUT-1.5)) otherwise.
