  • Publication number: 20230142356
    Abstract: A base station device is configured to set, for each communication terminal device, a radio format for signals transmitted to and received from the communication terminal device. The radio format is set for each communication terminal device in accordance with, for example, a type of use including a moving speed of the communication terminal device. The base station device may be configured to change the radio format for the communication terminal device based on the information about a change in the environment of a radio communication between the communication terminal device and the base station device and a change including the communication terminal device's location. The signals transmitted and received between the base station device and the communication terminal device include radio formats in which at least one of a length of a symbol of the signal and a length of a cyclic prefix in an OFDM scheme differs.

  • Patent number: 11641690
    Abstract: A high-speed communication system etc. are provided in New Radio (NR) and LTE. When a secondary base station device detects a data inactive state for all bearers, the secondary base station device notifies a master base station device of occurrence of the data inactive state regardless of absence of an inquiry from the master base station device. The data inactive state is a state in which downlink data for a communication terminal device is inactive. When the master base station device receives the notification about the occurrence of the data inactive state, the master base station device transmits a command to the communication terminal device to transition from an RRC_CONNECTED state to an RRC_INACTIVE state. Based on the command from the master base station device, the communication terminal device transitions to the RRC_INACTIVE state.

  • Publication number: 20230129048
    Abstract: The present invention has an object to provide a communication system capable of minimizing effects due to a delay among a plurality of base station devices as much as possible in scheduling for communication with a terminal device in cooperation among the plurality of base station devices. Cells1 to 3 can each perform scheduling without using information for scheduling notified from one or a plurality of cells among pieces of information for scheduling notified from other cells. For example, in a case where an interface between the cell1 and cell3 has a large delay amount, the cell1 performs scheduling without using information S13 notified to the cell1 by the cell3, and the cell3 performs scheduling without using information S11 notified to the cell3 by the cell1.

  • Publication number: 20230119586
    Abstract: Provided is a high-speed communication system with the high reliability and the low latency under New Radio (NR). A base station device includes a plurality of distributed units (DUs, 802) that transmit and receive radio signals, and a central unit (CU, 801) that controls the plurality of DUs (802). The CU (801) duplicates a downlink packet addressed to a communication terminal device (804), and forwards the duplicated downlink packet to each of at least two DUs (802) among the plurality of DUs (802). Each of the at least two of the DUs (802) transmits, to the communication terminal device (804) by the radio signal, the downlink packet obtained from the CU (801). Upon redundant receipt of the downlink packets, the communication terminal device (804) removes a redundant downlink packet in accordance with a predefined downlink packet removal criterion.

  • Patent number: 11625868
    Abstract: A centerline for generating network data of an indoor space can be generated while limiting the amount of calculation. Points where first straight lines and second straight lines constituting centerlines meet are created using re-entrant vertices (Step 1). The points created in Step 1 are connected by lines (Step 2). Connection lines corresponding to the longest sides are repeatedly deleted from closed polygons defined by the connection lines obtained in Step 2 until no closed polygons are left (Step 3). Each vertex of the connection lines obtained in Step 3 is connected to a farthest center point on the perimeter of the shape of the passage if there is such a farthest center point to which the vertex can be connected without touching the perimeter and without crossing other connection lines (Step 4).

  • Publication number: 20230091559
    Abstract: In a communication system, an eNB and a UE transmit and receive a UE monitoring message for confirming the state of the UE in a predetermined UE monitoring period. For example, in UE monitoring periods, a UE monitoring procedure is performed, so that the UE transmits the UE monitoring message to the eNB. Upon receipt of the UE monitoring message, the eNB transmits delivery confirmation information to the UE. The UE monitoring period is set as, for example, a period shorter than a TAU period. This allows the UE monitoring process to confirm the state of the UE even if the TAU period is lengthened. The eNB may transmit the UE monitoring message to the UE.
