Abstract
Provided is a high-speed communication system with the high reliability and the low latency under New Radio (NR). A base station device includes a plurality of distributed units (DUs,) that transmit and receive radio signals, and a central unit (CU,) that controls the plurality of DUs (). The CU () duplicates a downlink packet addressed to a communication terminal device (), and forwards the duplicated downlink packet to each of at least two DUs () among the plurality of DUs (). Each of the at least two of the DUs () transmits, to the communication terminal device () by the radio signal, the downlink packet obtained from the CU (). Upon redundant receipt of the downlink packets, the communication terminal device () removes a redundant downlink packet in accordance with a predefined downlink packet removal criterion.
