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 terminal is disclosed, which is capable of appropriately determining a resource to which a DCI is mapped. A DCI receiver (203) receives first and second downlink (DL) control signals, and a signal demultiplexer (202) demultiplexes a DL data signal from a received signal, using the first and the second DL control signals. The DCI receiver (203) identifies a resource for the second DL control signal based on information on the first DL control signal, or information on the DL data signal, indicated by the first DL control signal.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: The invention relates to an improved radio resource allocation performed by a vehicular mobile terminal. The vehicular mobile terminal determines whether to determine radio resources based on the location of the vehicular mobile terminal or not, based on information received from an entity of the communication system. In case the radio resources are to be selected based on the location of the vehicular mobile terminal, the vehicular mobile terminal determines the location of the vehicular mobile terminal, and determines radio resources for communication with at least the second mobile terminal, based on the determined location of the vehicular mobile terminal.

Abstract: UEs each monitor a search space in multiple CORSETs and appropriately detect a DCI. In a base station (100), a DCI generator (102) selects one of multiple cases each indicating a combination of CORSETs to be monitored by a terminal (200) among multiple control channel regions (CORSETs). A transmitter (106) indicates, by higher-layer signaling, configuration information indicating the multiple cases, and indicates the selected case by dynamic signaling.
