Publication number: 20230199903Abstract: A narrow-bandwidth terminal device performs radio communication at a bandwidth narrower than a system bandwidth. The narrow-bandwidth terminal device in an idle state camps on a cell, and performs discontinuous reception of a signal transmitted from the cell. The terminal device also determines a reception condition of the signal, for example, whether the signal can be received. When it is determined that the signal cannot be received, the narrow-bandwidth terminal device moves out of a coverage area of the cell while continuing to perform the discontinuous reception. When it is determined that a discontinuous reception timer has been completed, the narrow-bandwidth terminal device continues to perform the discontinuous reception.Type: ApplicationFiled: September 7, 2022Publication date: June 22, 2023Applicant: Mitsubishi Electric CorporationInventors: Mitsuru MOCHIZUKI, Kuniyuki SUZUKI, Masayuki NAKAZAWA, Noriyuki FUKUI, Haruka NOZAWA

Publication number: 20220167214Abstract: In a communication system according to the present invention, a UE and an MeNB perform both a direct communication and a communication through a SeNB. Along with moving of the UE, a handover process of switching the MeNB to which the UE is connected, from an S-MeNB to a T-MeNB is performed. The connection between the UE and the SeNB is maintained during the handover process. The UE starts transmitting data to the SeNB before a communication path between the UE and the MeNB is changed from a path formed by the S-MeNB and the UE to a path formed by the T-MeNB and the UE.Type: ApplicationFiled: February 14, 2022Publication date: May 26, 2022Applicant: Mitsubishi Electric CorporationInventors: Taiki TAGUCHI, Mitsuru MOCHIZUKI, Kuniyuki SUZUKI, Haruka NOZAWA
