Abstract: The present disclosure provides wireless communication methods for repeated transmission of channels, and wireless communication devices therefor. In one embodiment, the gap between the starting subframe of a first channel and the starting subframe of a second channel is defined or configured. In another embodiment, Mx*W=M and Mx*n=N is satisfied, where Mx is the number of subframes reserved for the channel in one HARQ process, M is RTT for one HARQ process, W is a positive integer and represents the maximum number of HARQ processes transmitting the channel within M subframes, N is the gap between the starting subframes of the channel in two HARQ processes, and n is a positive integer. In yet another embodiment, time-frequency resources for the channel in different HARQ processes are different.

Abstract: The present disclosure provides a wireless communication method and an eNode B and user equipment therefor. The wireless communication method performed by the eNB comprises steps of transmitting a first downlink control information (DCI) to a UE in a first physical downlink control channel (PDCCH) candidate or enhanced PDCCH (EPDCCH) candidate; and transmitting a second DCI to the UE in a second PDCCH candidate or EPDCCH candidate, wherein the assignment of the second PDCCH candidate or EPDCCH candidate is determined based on the assignment of the first PDCCH candidate or EPDCCH candidate according to a predefined algorithm configured through radio resource control (RRC) signaling or fixed by specification. According the present disclosure, the BD trials for DCIs can be reduced.

Abstract: A communication device which can reduce amount of control information, limit interference with other traffics, and prevent an increase in current consumption. In this device, a separation unit separates radio resource allocation information, specific section information and transmission parameter information from a received signal. A specific section information control unit selects a sub-carrier designated by the specific section information to allocate data to be transmitted to the own unit. A channel quality measuring unit uses a pilot signal to measure the channel quality of the selected sub-carrier. A channel quality information creating unit creates channel quality information indicating the measurement results input from the channel quality measuring unit. A multiplexing unit multiplexes the transmission signal with the channel quality information.

Abstract: Received Signal Strength Indicator (RSSI) is measured accurately even in a case where a discovery signal is transmitted. A receiver receives a plurality of subframes, at least one of which includes a discovery signal, and a measurer measures Reference Signal Reception Power (RSRP) using a first resource in which the discovery signal is mapped, measures RSSI using a second resource different from the first resource for which the discovery signal is mapped, and calculates Reference Signal Reception Quality (RSRQ) using RSRP and RSSI.

Abstract: Method of scrambling signals, transmission point device, and user equipment using the method are provided. The method includes: sending an ID table to a user equipment through higher layer signaling, the ID table being a subset of the whole ID space and containing available IDs for the user equipment; notifying the user equipment an ID in the ID table to be used through physical layer signaling or UE specific higher layer signaling; generating a random seed based on the notified ID; initializing a scrambling sequence by the random seed; and scrambling the signals with the initialized scrambling sequence. The method of the disclosure, by combining physical layer signaling and higher layer signaling, may notify the used group ID and the blind detection space to a UE, wherein the blind detection for the UE is enabled and the signaling overhead is reduced.

Abstract: A transmitting device includes a controller and a transmitter. The controller, in operation, adds an offset to a transmission power or a transmission power density of first data mapped in a remaining resource other than a data resource, to control a transmission power or a transmission power density of second data mapped in the data resource, for use of a second mapping pattern. A part of a resource on which a reference signal is to be mapped in a first mapping pattern of the reference signal is replaced with the data resource in a second mapping pattern of the reference signal. The transmitter, in operation, transmits a signal including the first data, the second data, and the reference signal.

Abstract: Provided are resource-utilization controlling methods for a device-to-device communication and wireless devices therefor. The method performed by a first wireless device comprises steps of: detecting current utilization state of the resource for the device-to-device communication as a resource utilization state; and explicitly or implicitly signaling the resource utilization state through broadcasting in the physical layer. The method performed by a second wireless device comprises steps of: receiving one or more resource utilization states explicitly or implicitly signaled from one or more other wireless devices; and determining whether and/or how to adjust the transmission behavior of the second wireless device based on the received one or more resource utilization states.
