Abstract: A UE includes an EUTRA-CMR reception unit that receives a codec mode request (EUTRA-CMR) including a codec mode that is determined by an eNB in accordance with a radio condition of the UE, a mode switching notification unit that notifies an encoder of switching to the codec mode included in the received codec mode request; and a mode switching acknowledgement unit that transmits a response message to the eNB when confirming that the encoder switches the codec mode.

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: In a terminal, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups (CBGs) configuring each of a plurality of transport blocks (TBs) assigned by the plurality of downlink control signals, a HARQ-ACK generation unit generates a response signal (HARQ-ACK) for each of the code block groups. A transmission unit collectively transmits the response signals for each of the code block groups.

Abstract: In a base station, a signal allocating unit allocates downlink control signals (DCI) to a control channel region (CORESET) constituted by a plurality of control channel elements (CCEs), and a transmitting unit transmits the downlink control signals. In this case, the number of resource element groups (REGs) that constitute the CCE is a power of 2, and a bundling size indicating the number of REGs included in the REGs that constitute the CCE and arranged in adjacent resource blocks is a power of 2.

Abstract: Provided are wireless communication devices and methods. A wireless communication device can comprise: circuitry operative to map at least a first type of reference signals (RSs) onto orthogonal frequency division multiplexing (OFDM) symbol (s) other than the OFDM symbols onto which shortened transmission time intervals (TTIs) are mapped in a subframe, each of the shortened TTIs comprising 1-7 OFDM symbols; and a transmitter operative to transmit a physical channel in one of the shortened TTIs and transmit at least the first type of RSs.

Abstract: In a base station, control circuitry determines, based on an offset for defining a frequency position of a narrowband allocated to an MPDCCH and a resource block group size of a system band, allocations of a first EPDCCH set and a second EPDCCH set that constitute the MPDCCH. The MPDCCH is a PDCCH for MTC. The second EPDCCH set has a different number of PRBs from the first EPDCCH set. A transmitter transmits a control signal according to the allocations of the first EPDCCH set and the second EPDCCH set. Further, the control circuitry controls a number of RBGs in which both the first EPDCCH set and the second EPDCCH set are allocated to be zero or one.

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: In a base station, a first setting circuitry sets a first Narrowband for allocating a system information block (SIB) for MTC by using a predetermined default offset. A second setting circuitry sets a second Narrowband for allocating a signal other than the SIB by using the default offset and an additional offset that indicates a difference from the default offset. An allocating circuitry allocates the SIB including the additional offset to the first Narrowband, and allocates the signal other than the SIB to the second Narrowband.
