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 methods for communicating within a communication system when re-configured from a source to a target uplink/downlink configuration. The invention is also providing mobile station for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. Specifically, the invention suggests to perform PUSCH transmissions in response to Downlink Control Information, DCI, transmissions such that the source uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received up to and including subframe N−6, a predefined uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received during subframes N−5 to N−1; and the target uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received from subframe N onward.

Abstract: A communication apparatus includes circuitry and a transmitter. The circuitry maps a precoded downlink control signal to one of a plurality of mapping candidates. The precoded downlink control signal is prepared using a first precoding for single-antenna port transmission with a single antenna port in localized allocation mode. The precoded downlink control signal is prepared using a second precoding for multi-antenna ports transmission with two antenna ports in distributed allocation mode. The plurality of mapping candidates is comprised of a plurality of aggregation levels, and one or more of the aggregation levels that is higher than a boundary among the plurality of aggregation levels is associated with only the multi-antenna ports transmission, the boundary being determined based on signaling indicated from the base station apparatus. The transmitter transmits the precoded downlink control signal.

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: The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.
