    Abstract: An infrastructure equipment that transmits a radio network identifier to a communications device for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment.

    Abstract: A method, base station, terminal and communication system for updating component carriers are provided. Wherein, status information of the terminal, base station and/or component carrier is acquired; whether the status information accords with the predetermined condition is determined; an old component carrier is replaced by a new component carrier, or a new component carrier is added in the even that the predetermined condition is met. With the embodiments of the present invention, the component carrier which the terminal would use is updated more effectively.

    Abstract: The present disclosure relates to a communication device and a communication method. The communication device according to one embodiment comprises an acquisition unit, a determining unit, and a trigger unit. The acquisition unit is configured to acquire distribution information of user devices in a dynamic network, said user devices at least comprising a slave device, the slave device in device-to-device communication acquiring a communication service by means of a master device. The determined unit is configured to determining a re-configuration method of the dynamic network on the basis of the acquired information. The trigger unit is configured to trigger the re-configuration of the dynamic network on the basis of the determined method.

    Abstract: A terminal and base station side device, a terminal device, a base station, and a wireless communication method. The terminal side device includes: a searching unit, configured to adopt a synchronization signal sequence corresponding to a target frequency range to be searched to search a target cell; and a synchronization unit, configured to perform synchronization based on the synchronization signal detected by the searching unit to synchronize the device to the target cell, the case the target frequency range belongs to a first frequency range, the searching unit adopts the synchronization signal sequence in a first subset of a synchronization signal sequence set to search the target cell, the first subset being a proper subset of the synchronization signal sequence set. Thereby, a number of synchronization signal sequence matching in a cell searching procedure is reduced and time for user equipment to synchronize to the target cell is shortened.
