초록
This paper presents performance evaluation results of physical random access channel in 5G new radio standard defined in 3GPP, which was derived from simulation assumptions such as preamble formats, wireless channel, signal-to-noise ratio. We assumed sampling rate of 61.44 Msps, 30 kHz subcarrier spacing, 3.7 GHz center frequency, and 40 MHz system bandwidth in the simulation. As the official performance requirements for new radio physical random access channel is not available yet at the moment, which is being discussed in the 3GPP meeting and by email, this paper refers to the requirements described in 3GPP release-13. Simulation results indicates that the performance of NR PRACH defined in 3GPP release 15 meets the requirements in release 13 at least in additive white Gaussian noise and extended typical urban channel.
