    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 selection of synchronization source among various synchronization sources which include sources determining the synchronization signal from the network such as base stations (network nodes) or user equipments which receive the synchronization signal possibly over other hops from the base station, and which further includes sources which do not determine their synchronization signal from the network. The selection of the synchronization source is performed by choosing the source with the most reliable synchronization signal based on a metric calculated for each of the sources considered. In particular, the metric is based on the type of the source, number of hops between the network and the source and/or received signal quality. After selecting the source, the timing of the device is adapted accordingly.

    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: 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: Disclosed is a base station capable of appropriately configuring a resource on which EPDCCH is located when soft combining is applied. The base station includes configuration section 102 that configures an EPDCCH set in a plurality of subframes, the EPDCCH set being formed of ECCEs to which control information (assignment information) transmitted over the plurality of subframes is assigned; and an assignment section 105 that assigns the control information to any of the ECCEs in each of the plurality of subframes.

    Abstract: Provided are D2D communication methods and D2D-enabled wireless devices. The D2D communication method performed by a D2D-enabled wireless device includes transmitting signals in D2D subframes with a randomization pattern. The randomization pattern is designed based on relative subframe positions in a virtual pure D2D subframe sequence composed of multiple D2D subframes in one or more radio frames. In another embodiment, the eNB scheduling based resource allocation and the D2D-enabled wireless device selection on its own based resource allocation share a same randomization pattern design.
