Abstract: In a terminal, in a case where the sum of the transmission power for a first signal and the transmission power for a second signal that requires lower latency and higher reliability than the first signal exceeds the maximum transmission power in an overlap interval in which a transmission of the first signal and a transmission of the second signal occur at the same time, a control unit carries out power scaling with the quality of the second signal being prioritized over the quality of the first signal, in at least the overlap interval. A transmission unit transmits the first signal and the second signal obtained after the power scaling.

Abstract: A base station includes: an allocating circuit that allocates, to a resource set which is monitored by a terminal belonging to a group, a first control signal which contains information indicating the configuration of a slot and a second control signal which does not contain the information indicating the configuration of a slot; and a transmitter that transmits the first control signal and the second control signal to a terminal. The number of symbols to which the first control signal is allocated is made equal to the smallest number of symbols to which the second control signal is allocated.

Abstract: A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.

Abstract: The present disclosure relates to a data transmitting device, data receiving device and the corresponding data transmitting method and data receiving method for transmitting/receiving data over a wireless channel in a communication system. In particular, a first resource grant is received for a data transmission in a subframe and a second resource grant for a data transmission of data in said subframe. Then, it is determined, according to which of the first resource grant and the second resource grant data are to be transmitted in the subframe; and the data is transmitted in the subframe according to the selected first grant or second grant.

Abstract: A DCI receiving unit receives downlink control information (DCI) indicative of allocation of an uplink (UL) signal of a first TTI (long TTI) or an uplink signal of a second TTI (sTTI) having a shorter TTI length than the first TTI; a transmission power determination unit determines transmission power of the uplink signal of the first TTI and transmission power of the uplink signal of the second TTI; and a transmitting unit transmits the uplink signal of the first TTI and the uplink signal of the second TTI by using the determined transmission power on the basis of the downlink control information. The transmission power determination unit reserves desired transmission power for the uplink signal of the second TTI in the first TTI in a case where decoding of the downlink control information indicative of allocation of the uplink signal of the second TTI to be transmitted within the first TTI (e.g., a subframe) is completed before start of transmission of the uplink signal of the first TTI.

Abstract: The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

Abstract: The present disclosure relates to a method for paging coverage extension UEs in a cell controlled by a radio base station. At least one CE-specific paging possibility is defined for paging CE-UEs. The CE-UEs in the cell regularly monitor the at least one CE-specific paging possibility. When the radio base station determines to page all the user equipments in the cell, it pages the CE user equipments in the cell at the CE-specific paging possibility, using a coverage extension technique. The disclosure also relates to a method for paging a CE-UE, which performs radio measurements by a CE-capable user equipment to determine whether coverage extension is necessary. The radio base station is informed about whether the CE-capable user equipment needs coverage extension and then pages the CE-UEs applying or not applying a CE technique depending on whether coverage extension is necessary.

Abstract: A receiver (202) receives the same downlink data over one or more subframes through a downlink resource within a narrow band for MTC terminal. A response signal generator (210) generates a response signal as a response to the downlink data. A transmitter (217) transmits the response signal through an uplink resource a predetermined number of subframes after the last subframe of the one or more subframes, the uplink resource being associated in one-to-one correspondence with the number of a downlink resource to which the downlink data is allocated in the last subframe.
