Abstract: The invention relates to a transmitting device, which performs a resource sensing procedure to acquire information about radio resources usable for transmitting data at a later point in time. After data becomes available for transmission, the transmitting device performs an autonomous radio resource allocation to select radio resources within a transmission window to be used for transmitting the data, based on the information acquired by the resource sensing procedure during a sensing window. The autonomous radio resource allocation comprises selecting radio resources in primary subframes of the transmission window preferably over radio resources in secondary subframes of the transmission window. The secondary subframes correspond to those subframes in the sensing window during which the transmitting device did not perform the resource sensing procedure, and the primary subframes correspond to those subframes in the sensing window during which the transmitting device did perform the resource sensing procedure.

Abstract: The invention relates to an improved semi-persistent resource allocation for a mobile terminal (MT) for transmitting periodic data. The MT transmits information on the periodic data to the radio base station (BS), such that the BS determines the different possible transmission periodicities and/or the different possible message sizes of the data components of the periodic data. The MT receives from the BS plural semi-persistent resource (SPS) configurations, each being usable to transmit at least one of the supported data components. The MT indicates to the BS the data components that are to be transmitted by the MT. The MT receives from the BS an activation command to activate one or more of the SPS configurations to periodically allocate radio resources for the MT to transmit each of the indicated data components. The MT then transmits the one or more data components based on the radio resources and the transmission periodicity as configured by the activated one or more SPS configurations.

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 invention relates to transmitting and receiving data in subframes of a wireless communication system. It includes at the user equipment receiving an uplink grant for transmitting data on predetermined resources of an uplink carrier; detecting by carrier sensing whether or not the predetermined resources are available for transmission; and if the predetermined resources are detected to be available for transmission, transmitting data in the predetermined resources and transmitting a transmission confirmation indication indicating that the data has been transmitted. At the receiving side, the transmission confirmation indication is transmitted and based on, the received data is handled.

Abstract: A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.

Abstract: A user equipment includes a receiver and a transmitter and is configured to report channel state information (CSI) to a base station in a communication system in which a plurality of downlink component carriers and at least one uplink component carrier are configured. The receiver receives, in a slot nTrigger, a trigger message that triggers reporting of the CSI for at least one unlicensed downlink component carrier of the plurality of downlink component carriers. The transmitter transmits, in a slot nReport, the CSI based on reference signals present in a slot nRS on the at least one unlicensed downlink component carrier. Responsive to the at least one unlicensed downlink component carrier being occupied for a period of time for a bursty downlink transmission, only the reference signals in the slot nRS are evaluated for the CSI, and other slots in the period of time are not evaluated for the CSI.
