摘要： A UE (101) wirelessly connects to an eNB (111) of company A. A UE (102) wirelessly connects to an eNB (112) of company D. At least one of the eNB (111) and the eNB (112) transmits broadcast information that indicates a predetermined bandwidth that is included in a radio frequency bandwidth assigned to company A and that can be used in direct communication between the UE (101) and the UE (102). The UE (102) uses the predetermined bandwidth and performs the direct communication with the UE (101), based on the transmitted broadcast information.

摘要： An RN (100) is a relay apparatus of a communication system that includes a UE and an eNB that after a given period that starts after the transmission of a wireless signal to the UE, receives delivery confirmation information concerning the transmitted wireless signal. A DL receiver (110) receives and decodes the wireless signal transmitted by the eNB. A relay determiner (130) determines whether the wireless signal decoded by the DL receiver (110) is subject to relay by the RN (100). If the relay determiner (130) determines that the wireless signal is subject to relay, a relay information generator (140) and a UL_PHY processor (150) notify the eNB of relay information indicating that the wireless signal is to be regenerated and relayed. A DL transmitter (170) transmits to the UE, the wireless signal that has been determined to be subject to relay by the relay determiner (130).

摘要： A terminal (120) adjusts a transmission count of consecutive transmissions of the same data to a base station (110), based on a radio resource count of radio resources assigned to the terminal (120) among radio resources of a control channel received from the base station (110). The base station (110) identifies the transmission count based on the radio resource count of the radio resources assigned to the terminal (120) among the radio resources of the transmitted control channel, and based on the identified transmission count, receives the same data consecutively transmitted by the terminal (120).

摘要： The wireless communication system includes a base station (10) and a mobile station that communicates with the base station (10). The base station (10) includes a sending unit (17). The sending unit (17) sends, to the mobile station, a first signal that indicates, as a notification, reduction of the number of candidates for channels each of which includes control information addressed to the mobile station. The mobile station includes a receiving unit and a number-of-candidates reducing unit. The receiving unit receives the first signal sent by the sending unit (17). The number-of-candidates reducing unit monitors one or a plurality of channels the number of which has been reduced, from the candidates, based on the first signal and acquires the control information from the one or the plurality of channels.
