(Note)
【計算 SNR】
  1. [CRC.ind] Effective SNR => Value: 0-255, representing -64dB to 63.5dB, with 0.5dB step size. 
     actual SNR(dB) = (Effective SNR) * 0.5 - 64
		
  2. [RX_ULSCH.ind] UL_CQI => Value: 0-255, representing -64dB to 63.5dB, with 0.5dB step size. 
     actual SNR(dB) = (UL_CQI) * 0.5 - 64
	
  3. [HARQ.ind] PUCCH SINR => Value: 0-255, representing -64dB to 63.5dB, with 0.5dB step size. 
     actual SINR(dB) = (Effective SNR) * 0.5 - 64
		
【計算 RSSI】
  4. [RACH.ind] Per resource RSSI => Value: 0-255, representing -127.5 dBFS up to 0 dBFS, with 0.5 dB step size. 
     actual RSSI(dBFS) = (RSSI) * 0.5 - 127.5
		
  5. [CRC.ind] RSSI => Value: 0-255, representing -127.5 dBFS up to 0 dBFS, with 0.5 dB step size. 
     actual RSSI(dBFS) = (Per resource RSSI) * 0.5 - 127.5
		
  6. [HARQ.ind] PUCCH RSSI => Value: 0-255, representing -127.5 dBFS up to 0 dBFS, with 0.5 dB step size. 
     actual RSSI(dBFS) = (PUCCH RSSI) * 0.5 - 127.5
	
  7. [CRC.ind] Received Noise and Interference Power => Value: 0-255, representing -127.5 dBFS up to 0 dBFS, with 0.5 dB step size. 
     actual Received Noise and Interference Power(dBFS) = (Received Noise and Interference Power) *0.5 - 127.5
