Publication number: 20230300796Abstract: In a communication system, a plurality of base stations includes an MeNB being a first base station, and a plurality of SeNBs to be connected to the MeNB. At least one of control plane data about control of communication and user plane data about a user is transmitted to and received from a user equipment (UE) via the first base station being the MeNB. The control plane data and the user plane data are contained in information provided by a core network about communication with the UE. The communication system can simplify processing of at least one of control plane data and user plane data when a communication terminal device communicates with a plurality of base station devices.Type: ApplicationFiled: April 20, 2023Publication date: September 21, 2023Applicant: Mitsubishi Electric CorporationInventors: Masayuki NAKAZAWA, Mitsuru MOCHIZUKI, Hideo UMEHARA, Kuniyuki SUZUKI

Publication number: 20180191544Abstract: A technique to a radio communication system, a base station, and a radio communication method achieving switching of analog control such as phase or amplitude control, while suppressing reduction in power efficiency resulting from a multipath propagation channel. The radio communication system relating to this technique makes radio communication through transmission and reception of a plurality of radio communication frames. The plurality of radio communication frames includes successive radio communication frames, at least one of which is a radio communication frame including an effective symbol, and a cyclic prefix and a non-transmission interval added to the effective symbol.Type: ApplicationFiled: July 12, 2016Publication date: July 5, 2018Applicant: Mitsubishi Electric CorporationInventors: Hideo UMEHARA, Kuniyuki SUZUKI, Mitsuru MOCHIZUKI
