Study on channel model for Indonesia 5G networks

Abstract

The fifth telecommunication generation (5G) is expected to be deployed in 2020 with significant improvement and services. This paper studies a preliminary model of Indonesia 5G channels based on statistical spatial channel model (SSCM) for operating frequency of 28 GHz. We calculate the estimate channel capacities of Indonesia 5G (per link) from the obtained power delay profile (PDP) to observe the outage probability representing the theoretical performances of 5G in Indonesia. The outage probability is calculated from the probability when the channel capacity C dropped into a value below the channel coding rate R with a probability of P (R ≥ C) due to the dynamic fading, indicating a failure of detection. The outage probability is in detail analyzed in this paper since it is expected to be used as a reference performance of 5G in Indonesia. We conduct a series of computer simulations to evaluate the performance of Indonesia 5G under the obtained channel model based on cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) with a channel coding scheme. We found an agreement in terms of diversity of practical and theoretical outage probability confirming a good estimation of the performance of 5G in Indonesia. The results are expected to be useful to assist real-field 5G experiments in Indonesia and help optimal design and implementation of Indonesia 5G networks in Indonesia.
