Title: COMMUNICATION SYSTEM
Abstract:
Provided is a New Radio (NR) communication system which is fast and has high reliability and small delay. A base station device includes a plurality of Distributed Units (DU) (802) which transmit and receive wireless signals, and a Central Unit (CU) (801) for controlling the plurality of DUs (802). The CU (801) reproduces a downlink packet addressed to a communication terminal device (804) and transfers the downlink packet to at least two DUs (802) among the plurality of DUs (802). The at least two DUs (802) transmit the downlink packet acquired from the CU (801) to the communication terminal device (804) using a wireless signal. The communication terminal device (804), upon receiving downlink packets overlapping each other, deletes an overlapping downlink packet in accordance with a predetermined downlink packet deletion standard.
