In a network having an edge server disposed therein, to appropriately construct a wireless communication route used in communication between the edge server and a user terminal, a processor of a network control device acquires group information related to grouped base stations in multiple base stations disposed in the network, acquires route information related to one or more wireless communication routes formed by multi-hop communication between the grouped base stations, and transmits the group information and the route information to an edge server connected to one of the base stations or to a user terminal.

A transmission method makes it possible to transmit data from a first node device to a second node device belonging to a network neighbourhood of the first node device, the first and second node devices belonging to an electrical supply network. These nodes are configured for transmitting the data by powerline and by radio frequency. The method comprises the following steps performed by the first node device: distributing the data in two groups of data by an operation of interlacing the data, each group being associated with a communication medium from powerline and radio frequency, and transmitting each data item to a MAC layer of the communication medium associated with the group to which the data item belongs.

A transmission method for transmitting a fragment of an IP packet from a first node device to a third node device through a second node device. The first and second node devices are configured for communicating by powerline and by radio frequency. The second and third node devices can communicate only using a single communication medium from powerline and radio frequency. A first fragment sent by said first node device either by powerline or by radio frequency is received. An acknowledgement message is sent by to said first node device using a second communication medium selected from powerline and radio frequency so that it is different from said single medium. Then said first fragment is transmitted to said third node device using said single communication medium.

A communication technology for communication between at least one application and an external device uses subscriber identification modules that correspond, respectively, to wireless communication services. In the technology, first information for determination of a transmission power value is acquired for each of the wireless communication services. In the technology, second information for determination of a delay time allowed by the at least one application is acquired. In the technology, a wireless communication service is selected from among the wireless communication services for the communication based on the first information and the second information.

By a vehicle wireless communication device or a vehicle wireless communication method, for each wireless communication service, a power headroom representing a remaining power of a transmission power with respect to a predetermined maximum transmission power is calculated, a delay allowable amount is acquired, and the wireless communication service is selected for communication between at least one in-vehicle device and an external device.

A wire device receives: configuration parameters of: a primary cell with a primary physical uplink control channel (PUCCH); and a secondary cell with a secondary PUCCH; a transmit power control (TPC) radio network temporary identifier (RNTI); a primary TPC index of the primary PUCCH; and a secondary TPC index of the secondary PUCCH. The wireless device receives a downlink control information (DCI) associated with the TPC RNTI. The secondary TPC index identifies a TPC command in an array of TPC commands in the DCI. The wireless device adjusts a transmission power of the secondary PUCCH based on the TPC command.
