    Abstract: The disclosure relates to a method for allocating radio resources to a user terminal for performing communication between a radio control entity and the user terminal in a communication system. At least first predetermined radio resources are configured in the user terminal for use in connection with a particular carrier and are associated with a particular format of a downlink control information, DCI, message. The user terminal receives a DCI message of the particular format from the radio control entity. Upon receiving the DCI message of the particular format, the user terminal identifies the first predetermined radio resources associated with this received DCI message, and using the identified first predetermined radio resources for communication between the user terminal and the radio control entity via the particular carrier. The particular carrier can be an unlicensed carrier.

    Abstract: The present disclosure relates to a mobile station (UE) for receiving Physical Downlink Control CHannel, PDCCH, assignments in a mobile communication system including serving cells. In case the mobile station is configured with at least two serving cells having different serving cell indices, the UE monitors, for the two serving cells, a same set of candidates for PDCCH assignments defining a same UE-specific search space and which is determined independently of the indices of the serving cells with which the UE is configured, and the UE receives, for the serving cells, PDCCH assignments from among the monitored same set of candidates using carrier indicator field, CIF, values in the received PDCCH assignments for identifying the serving cells with which the UE is configured. The CIF values, included in the received PDCCH assignments, correspond to the respective indices of the serving cells with which the UE is configured.

    Abstract: The present invention relates to a transmitting terminal for transmitting data to a receiving terminal over a direct link connection. The transmitting terminal comprises a receiving unit that receives from at least one neighboring terminal direct link timing information generated at the respective neighboring UE for determining the timing of the data transmission over the direct link. A generating unit generates derived direct link timing information based on the received direct link timing and which can be used for generating a derived direct link transmission timing value for determining the timing of the data transmission over the direct link. A transmitting unit transmits to the receiving terminal the derived direct link timing information.
