  • Publication number: 20210132565
    Abstract: A programmable controller allocates times obtained by dividing executable time in one operation cycle to a plurality of paths, executes sequence programs of the paths in the respective allocated times, and accumulates remaining time as extra time when execution of each of the sequence programs ends before the end of the allocation time. When it is determined that surplus time occurs on the basis of the accumulated extra time, the programmable controller determines whether each of the sequence programs is executed after being divided, and executes a remainder of a divided sequence program in the surplus time in accordance with a result of the determination.

  • Publication number: 20210132566
    Abstract: A programmable controller allocates times obtained by dividing executable time in one operation cycle to a plurality of paths, executes sequence programs of the paths within the respective allocated times, and measures extra time that is a remainder of each of the allocation times when execution of each of the sequence programs ends. Then, the programmable controller determines whether a predetermined sequence program is to be executed in the measured extra time, and instructs the sequence execution unit to execute the predetermined sequence program in the extra time in accordance with a result of the determination.

  • Publication number: 20210120486
    Abstract: A communication system includes a base station configuring an energy saving cell (ES cell) and a base station configuring a compensation cell (Comp cell). The ES cell is switchable between a switch-on state and a switch-off state. The Comp cell compensates for the coverage of the ES cell when the ES cell is in the switch-off state. Before the Comp cell starts compensating for the coverage, for example, before the ES cell decides to switch itself off in Step ST2101, in Step ST2201 for example, the base station configuring the ES cell notifies the UE being connected with the ES cell of the information about a Comp cell, for example, a Comp cell list.

  • Patent number: 10959283
    Abstract: 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.

Each of the cells includes a plurality of antenna elements, and performs radio communication with a communication terminal device through the antenna elements. Each of the cells notifies the other cells of settings for measuring channel information on a channel for performing radio communication of its own cell. Each of the cells may notify a communication terminal device being served thereby of the settings for measuring the channel information of its own cell. Here, the communication terminal device measures the channel information based on the settings notified from each of the cells, and reports a result of the measured channel information to a corresponding one of the cells when the result satisfies a predetermined reporting condition.

  • Patent number: 10893421
    Abstract: The present invention has an object to provide a communication system capable of appropriately providing services while improving a data rate using carrier aggregation. In Step ST1408, of a cell1 and a cell2 of a base station A, RRC connection is established between the cell1 and a UE, and the cell1 becomes a primary cell (PCell). Then, in Step ST1418, the cell1 determines to configure the cell2 as a secondary cell (SCell) to be aggregated with the own cell. Then, the cell1 notifies the UE of the above in Step ST1419. Upon this notification, the operation of restricting access to the cell2 from the UE is stopped by an MME, and thereafter, communication between the UE and the cell2 is started in Step ST1422.

  • Publication number: 20200359377
    Abstract: A communication system capable of a stable communication operation between a base station device and a communication terminal device. A UE is configured to communicate with an MeNB directly or through a SeNB. The UE is set to transmit, to the MeNB and the SeNB, transmission data addressed to the MeNB when an amount of the transmission data exceeds a predetermined threshold. The UE is set to transmit the transmission data not to the SeNB but to the MeNB when the amount is smaller than or equal to the threshold. The threshold is changed so that the transmission data is transmitted to the MeNB and the SeNB, when the SeNB is set to communicate with the UE with radio resources periodically allocated and the amount of the transmission data is smaller than or equal to the threshold.
