摘要： A wireless communication device, e.g., a mobile station, capable of performing its communication and relay processing for another mobile station, when requested, at the same time without stopping the communication and the relay processing. In the device, an outgoing/incoming call request detection unit (106) detects an outgoing/incoming call request indicating that an outgoing call of the signal of the mobile station or an incoming call is requested from a signal inputted from an upper-layer processing unit (105). A relay request detection unit (108) detects a relay request signal indicating that an MS1 requests an MS2 for relay to a base station from a demodulated relay signal inputted from a relay signal demodulation unit (107). A communication rate determination unit (109) determines the communication rate so as to simultaneously transmit both the signal of the mobile station and the relay signal when a signal indicating that an outgoing/incoming call request is detected is inputted from the outgoing/incoming call request detection unit (106) or a signal indicating that a relay request signal is detected is inputted from the relay request detection unit (108).

摘要： Disclosed is a wireless communication device that, when both localized transmission and distributed transmission are used, can obtain channel estimation accuracy equivalent to that of localized transmission with distributed transmission. With this device, a setting unit (108) sets the power density of a reference signal by setting the arrangement density in the time domain of the reference signal according to the continuity in the frequency domain of the reference signal. In addition, the setting unit (108) increases the arrangement density in the time domain of the reference signal as the continuity decreases. A transmission RF unit (111) transmits a reference signal having the power density that has been set by the setting unit (108).

摘要： There are provided a communication device, a base station, a communication system, and a communication method that make it possible to yield a diversity effect by cooperative relay without involvement of disproportionateness in data received by an eNB even when one of parties has unsuccessfully exchanged data. After received an ACK signal from a repeater 1, a repeater 2 which has transmitted a NACK signal in procedure 7 transmits data S2 to the eNB by use of its own resource, thereby making its own resource available for the repeater 1 (the repeater 2 does not use its own resource, and the repeater 1 uses the resource of the repeater 2). In procedures 8, the repeater 1 has received the NACK signal from the repeater 2 and subsequently transmits data S1 to the eNB by use of its own resource. Subsequently, the repeater 1 which has received the MACK signal in procedure 9 determines that the resource of the repeater 2 is available and transmits data P1 to the eNB by use of the resource of the repeater 2. In procedure 10, the repeater 1 transmits previously-generated data P2 to the eNB by use of its own resource.
