Abstract: Provided are a wireless communication terminal device and a power allocation method, wherein transmission channel quality information, regarding a Pcell having a high probability that UCI is multiplied therein, can be accurately estimated by an SRS having high priority in power allocation, and an eNB can instruct appropriate transmission power to an UL channel which transmits the subsequent UCI. A power scaling detection unit detects whether or not a total transmission power value of the UL channels transmitted by the plurality of CC exceeds the maximum transmission power specific to the UE. When a plurality of SRS are simultaneously transmitted using a Pcell and a Scell, and power scaling occurs, a power scaling control unit performs power allocation so that transmission power of the SRS of the Pcell has the higher priority than that of the SRS of the Scell.

Abstract: A radio communication terminal that increases the ACK/NACK resource utilization efficiency while preventing ACK/NACK collision, and that causes no unnecessary reduction of the PUSCH band in a system that transmits E-PDCCH control information. The radio communication terminal adopts a configuration including a receiving section that receives a control signal including an ACK/NACK index via an enhanced physical downlink control channel (E-PDCCH) transmitted using one configuration from among one or a plurality of configuration candidates, a control section that selects a resource to be used for an ACK/NACK signal of downlink data from among specified resources specified beforehand based on E-PDCCH configuration information used for transmission or reception of the E-PDCCH and the ACK/NACK index, and a transmitting section that transmits the ACK/NACK signal using the selected specified resource.

Abstract: Disclosed is a base station apparatus which allows an idle mode UE, in a small cell using S-NCT, to recognize the small cell and to receive a DCI. The base station apparatus is configured to use a carrier configuration which has no region for mapping a PDCCH and in which an EPDCCH is mapped in a data region. The base station apparatus includes: master information generating section 101 configured to generate allocation information indicating a resource which forms a search space in the EPDCCH and being scrambled with a cell ID of the base station apparatus; and transmitting section 107 configured to transmit the allocation information, a detection signal indicating the cell ID, and a control signal assigned in the search space.

Abstract: Provided are D2D wireless communication methods and UEs therefor. In one embodiment, the D2D wireless communication method performed by a UE includes continuing D2D transmission by using a resource from a resource pool allocated for mode 2 operation when switching from mode 1 operation to mode 2 operation. In another embodiment, the D2D wireless communication method performed by a UE includes performing D2D transmission by using a resource from a resource pool allocated for mode 2 operation, wherein the resource pool is indicated by a dedicated RRC signaling transmitted by an eNB, a SIB transmitted by an eNB, a PD2DSCH transmitted by other UE(s), and/or pre-configuration, and the dedicated RRC signaling, the SIB, the PD2DSCH and the pre-configuration are in descending order in priority when determining the resource pool.

Abstract: The invention relates to a method for transmitting a periodic channel quality report (CSI) and/or a sounding reference symbol (SRS) from a UE to an eNodeB. To avoid double decoding at the eNodeB in transient phases, a deterministic behavior of the UE is defined by the invention, according to which the eNodeB can unambiguously determine whether the UE will transmit the CSI/SRS or not. According to one embodiment, the UL grants and/or DL assignments received until and including subframe N-4 only are considered; UL grants and/or DL assignments received by the UE after subframe N-4 are discarded for the determination. Additionally, DRX-related timers at subframe N-4 are considered for the determination. In a second embodiment, DRX MAC control elements from the eNodeB, instructing the UE to enter DRX, i.e., become Non-Active, are only considered for the determination if they are received before subframe N-4, i.e., until and including subframe N-(4+k).

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 the base station a timing command for adjusting an uplink transmission timing value for data transmissions to the base station. A generating unit generates direct link timing information, based on the uplink transmission timing value, the direct link timing information being usable for generating a 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 generated direct link timing information, the direct link timing information being usable at the receiving terminal for generating a direct link reception timing value for determining the reception timing of data to be received on the direct link from the transmitting terminal.

Abstract: A wireless communication terminal capable of increasing the utilization efficiency of ACK/NACK resources and suppressing unnecessary PUSCH band reduction while avoiding ACK/NACK collision. The wireless communication terminal has a configuration provided with: a reception unit for receiving a control signal including ARI via an E-PDCCH set from among one or a plurality of E-PDCCH sets; a control unit for determining an offset value indicated by the ARI on the basis of whether or not a resource region that may be taken by a dynamic ACK/NACK resource corresponding to the E-PDCCH set that has received the control signal and a resource region that may be taken by a dynamic ACK/NACK resource corresponding to another E-PDCCH set overlap, and imparting an offset to the ACK/NACK resource according to the value of the ARI; and a transmission unit for transmitting the ACK/NACK signal using the determined ACK/NACK resource.

Abstract: Provided are wireless communication methods for D2D communication and UEs therefor. A wireless communication method involves transmitting either a first DCI or a second DCI based on whether a first UE and a second UE are to be in a communication type of groupcast or unicast. In the wireless communication methods, the first DCI and the second DCI are scrambled by the UE ID of the second UE if the first UE and the second UE are in the communication type of unicast upon transmitting the first DCI and the second DCI, and the first DCI and the second DCI are scrambled by the group ID if the first UE and the second UE are in the communication type of groupcast upon transmitting the first DCI and the second DCI.
