|1. (WO2018127982) RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD|
|Title:||RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD|
The purpose of the present invention is to provide a radio communication device, a radio communication system and a radio communication method which, to achieve ultra-reliable, low-delay communication, can perform transmission and receiving processing desirable when processing relating to data linkage has been removed from the RLC layer of a transmission device. [Solution] In order to solve the problem and meet the purpose, this radio communication device, which numbers and transmits multiple pieces of data to another radio transmission device, is provided with a control unit which, in the case that specific data of the multiple pieces of data have been discarded after numbering and before transmitting, transmits the multiple pieces of data after the aforementioned discarding to the other radio communication device without performing numbering, and transmits, to the other radio communication device, discard notification information notifying of the discarding.
