Abstract: A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.

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.

Abstract: Aspects of the subject disclosure may include, for example, distinguishing between offload and non-offload traffic associated with a mobile device in communication with a small-cell access point using a managed cellular frequency spectrum. The access point is located at a subscriber premises and in further communication with a network core. Offload traffic is associated with a first IP address of the mobile device and includes a signaling portion and a user data portion. User data messages of the user data portion are exchanged between the mobile device and the equipment at the subscriber premises without being exchanged between the network core and one of the mobile device, the equipment at the subscriber premises or both. The mobile device is associated with a first access point name identifier based on the first IP address and a second access point name identifier based on a second IP address. Other embodiments are disclosed.

Abstract: The coverage control method includes at least: step S101 of detecting that a load of an own cell is higher than a predetermined threshold (Lth1) when there is another cell whose coverage partially overlaps the own cell; step S103 of selecting an accommodation candidate cell that is a candidate to which a mobile station accommodated in the cell is unloaded, from the another cell based on a load condition related to a communication load that is a coverage control execution target; step S106 of selecting a continuously accommodated mobile station that is a mobile station that continues to be a coverage control target of the own cell, from the mobile station accommodated in the own cell based on radio quality of the selected accommodation candidate cell; and step S107 of controlling a coverage of the own cell by targeting at the selected continuously selected mobile station.

Abstract: A terminal device for use in a wireless telecommunications system including plural terminal devices operable to communicate with one another in a device-to-device manner. The terminal device includes a controller and a transceiver configured to operate together to cause the terminal device to determine a transmission power level to use for device-to-device transmissions from the terminal device to restrict a number of other terminal devices able to receive the device-to-device transmissions to a restricted subset of the other terminal devices, and to transmit device-to-device communications using the determined transmission power level. The terminal device may determine the transmission power itself or from control signalling reads received from network infrastructure equipment, such as a base station or roadside unit.

Abstract: A method and apparatus for obtaining radio access network (RAN) sharing information in a wireless communication system is provided. For an overload procedure, an evolved NodeB (eNB), which is shared by a plurality of operators, receives an indication of overloaded operator from a mobility management entity (MME), and performs an overload action for the overloaded operator indicated by the indication. Further, for a load balancing procedure, a first eNB, which is shared by a plurality of operators, receives a status report per operator from a second eNB, which is shared by the plurality of operators, and performs a load balancing action based on the status report.

Abstract: A communication system is provided that, if a large number of small cells are installed, is capable of configuring an operation suitable for small cells through simple operation and administration. If a small cell installed in Step ST1401 judges in Step ST1403 that a coverage macro cell, which includes the small cell in the coverage of the coverage macro cell, is present as a result of neighbor cell search in Step ST1402, notifies the coverage macro cell and another neighbor cell of its own capability in Steps ST1404 and 1405. The coverage macro cell selects a configuration parameter suitable for the capability of the small cell in Step ST1406 and notifies the small cell in Step ST1407. The small cell recognizes an operation mode configured by the coverage macro cell from the configuration parameter notified from the coverage macro cell, and then, starts operating in the operation mode.

Abstract: A method and apparatus for transmitting a cell shaping/un-shaping indication in a wireless communication system is provided. A first eNodeB (eNB) transmits a cell shaping/un-shaping indication which indicates cell shaping/un-shaping of a cell, managed by the first eNB, in an active antenna system (AAS) to a second eNB. The cell shaping means that main coverage of the cell is maintained unchanged but an edge of the cell can be adapted to load demand. The cell un-shaping means that coverage of the cell goes back to original coverage.
