    Abstract: A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

    Abstract: A communications device acting as a relay device including a controller configured in combination with a transmitter and a receiver to receive from a remote communications device a first random access preamble message, the first random access preamble message comprising an identifier of the remote communications device, to transmit, in response to the first random access preamble message, a random access response message to the remote communications device, the random access response message comprising an indication of communications resources allocated to the remote communications device, to receive, from the remote communications device and using the communications resources indicated in the random access response message, a scheduled transmission comprising a connection request message and a first contention resolution identifier, and to transmit to the remote communications device a second contention resolution identifier.

    Abstract: An infrastructure equipment transmitting/receiving data to/from one or more communications devices in a wireless communications network, includes a transmitter, receiver, and controller controlling the transmitter and receiver to provide a wireless access interface providing communications resources arranged in time divided units of a system bandwidth providing plural blocks of communications resources, and one or more narrowband carriers. Each carrier provides, within a carrier frequency bandwidth, communications resources for allocation to narrow band communications devices, the carrier bandwidth being less than and within the system bandwidth, signals being transmitted to the narrowband communications devices via the narrow band carriers with a first power. The controller controls the transmitter to transmit signals on a down-link of a narrowband carrier to a narrow-band communications device with an increased power, power of the signals being increased to a greater second power to reduce a time of communicating a high priority message.

    Abstract: [Object] To make it possible to prevent a load from being concentrated on a specific node when a frequency band is shared between the cellular system employing the HetNet and other systems.[Solution] Provided is an apparatus, including: an acquiring unit configured to acquire band-related information that is related to a frequency band available to a macro cell base station of a cellular system among shared bands shared between the cellular system and another system and is provided from a controller for a plurality of macro cell base stations of the cellular system; and a control unit configured to decide a frequency band available to a small cell base station corresponding to the macro cell base station among the frequency bands available to the macro cell base station.
