if last 4 digits of your student ID are 7281, then a = 7, b=2, c= 8, d = 1. This problem relates to the 5G NR standard. Consider the 5G frame structure given in the figure below. It is known that Answer the following questions: One frame, Tirame - 10 ms Af 15 kHz Af=30 kHz Af=60 kHz Af=120 kHz AF-240 kHz #0 #1 One subframe, Tsubframe = 1 ms #2 One slot, 0.5 ms One slot, 0.25 ms #3 One slot, 0.125 ms One slot, 0.0625 ms Also given is the following information. #5 One slot, 1 ms #7 #8 Table 4.3.2-1: Number of OFDM symbols per slot, slots per frame, and slots per subframe for normal cyclic prefix. 0 1 2 3 4 Nslot symb 14 14 14 14 14 Nframe slot 10 20 40 80 160 Nsubframe slot 1 2 4 8 16 1) What is the duration of a slot for a subcarrier spacing (SPS) of allowed value that is closest to 10c + d kHz? 2) What is the duration of an OFDM symbol (not including the cyclic prefix) for the SPS given in a)? 3) How many OFDM symbols are per slot? 4) What is the duration of the normal cyclic prefix per OFDM symbol for the case in 1)?
