Publication number: 20240121793Abstract: Provided is a communication system capable of suppressing increase in the power consumption of a communication terminal device, degradation in the communication quality, and reduction in the use efficiency of radio resources. A base station device (gNB) notifies a communication terminal device (UE) of information on the next reception timing. The UE receives, for example, a downlink control signal in a subframe. The UE obtains, from the downlink control signal, information on a piece of user data in the subframe, and the information on the next reception timing. The UE transmits and receives the piece of user data to and from the gNB. The information on the next reception timing indicates a subframe as the next reception timing of the UE. The UE receives a downlink control signal in the subframe.Type: ApplicationFiled: December 18, 2023Publication date: April 11, 2024Applicant: Mitsubishi Electric CorporationInventors: Mitsuru MOCHIZUKI, Tadahiro SHIMODA, Noriyuki FUKUI, Masaaki KUSANO
