Abstract: The present disclosure relates to a terminal and a base station as well as to a method which may be performed at a terminal and at a base station in a communication system. For example, a mobile device may comprise a transceiver, which, in operation, receives and/or transmits a signal, as well as a circuitry. The circuitry monitors a signal in a first set of resources. When the monitored signal includes identification of the mobile device and an indicator having a first value, controls the transceiver: to receive or transmit signal on a second set of resources and to, after a time period indicated in the monitored control signal, not receive or transmit signal on a second set of resources and monitor the control signal in the first set of resources

Abstract: An integrated circuit includes control circuitry and transmitting circuitry. The control circuitry maps data or a reference signal onto resources including orthogonal subcarriers of a first numerology and a second numerology, which differ at least by subcarrier spacing and are frequency-multiplexed on a subcarrier basis. The control circuitry assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology. The subcarriers of the second numerology include: inter-numerology-orthogonal subcarriers, each of which is centrally aligned with a subcarrier of the first numerology, and non-inter-numerology-orthogonal subcarriers not centrally aligned with any subcarrier of the first numerology and located between two adjacent subcarriers of the first numerology. The control circuitry assigns no transmit power to at least one of the non-inter-numerology-orthogonal subcarriers. The transmitting circuitry transmits the mapped data or reference signal.

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: A terminal is disclosed, which is capable of appropriately determining a resource to which a DCI is mapped. A DCI receiver (203) receives first and second downlink (DL) control signals, and a signal demultiplexer (202) demultiplexes a DL data signal from a received signal, using the first and the second DL control signals. The DCI receiver (203) identifies a resource for the second DL control signal based on information on the first DL control signal, or information on the DL data signal, indicated by the first DL control signal.

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: A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.
