| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 107 === Narrowband Internet of Things (NB-IoT) is a new 3GPP standard aiming to support a massive number of device features long range, low complexity, low power, and low data rate. The 5th generation mobile communication (5G) massive machine type communication (mMTC) field will base on NB-IoT system. In this paper, we use mathematical analysis to verify the performance of the timing advance random access procedure (TARA) of the NB-IoT system and compare with the traditional random access (RA) procedure. TARA procedure allows some of collision NB-IoT devices in the traditional RA procedure to have the opportunity to complete the RA procedure by match function between the timing advance value from base station and the timing advance value stored in NB-IoT device. From mathematical analysis, we found that TARA procedure can increase the access success probability and reduce the average access delay.
