20150327047 | Proximity Service in Communications - Two physical layer user terminal capability alternatives are introduced for device-to-device discovery for FDD mode terminals: a full discovery physical layer capability, and a partial discovery physical layer capability. The full discovery physical layer capability corresponds to an alternative where a discovery-capable user terminal has a capability to perform both Discovery_Scan (on an uplink band) and Discovery_Tx (on a downlink band) operations. A Discovery_Tx operation corresponds to transmission of a discovery signal to another user terminal directly over the air. A Discovery_Scan operation corresponds to reception of the discovery signal from another user terminal directly over the air. The partial discovery physical layer capability corresponds to an alternative where the discovery-capable terminal has a capability to perform either Discovery_Scan operation (on the downlink band) or Discovery_Tx (on the uplink band) operation (or both). | 11-12-2015 |

20110117907 | Selection of Connection Type in Cellular System - The present invention presents a method and a controller for selecting the type of connection used to connect a terminal device to a serving base station. The connection type is selected on the basis of monitored communication-environmental parameters of the terminal device. The selection is made between a direct cellular radio connection and a relayed cellular radio connection. The relayed connection is established through another terminal device acting as a relay terminal for the connection being relayed. A direct device-to-device link between the two terminal devices is established as a cognitive radio connection, and a radio access technology and communication parameters of the device-to-device link may be negotiated between the terminal devices. The relay terminal then links the device-to-device link to a direct cellular radio connection between the relay terminal and the serving base station. | 05-19-2011 |

20130336178 | TDD Data Transmission on Multiple Carriers with Sub Frames Reserved for Predetermined Transmission Directions - Apparatus and method for communication are provided. The apparatus includes a controller for controlling the transmission and reception of data on one or more carriers utilizing Time Division Duplexing and frames including sub frames, where multiple carriers utilized by different apparatuses are synchronized with each other and a predetermined number of sub frames of each frame are reserved for predetermined transmission directions and a scheduler for allocating the rest of the sub frames carrier specifically either in downlink or uplink direction. | 12-19-2013 |
