    摘要： A communication method includes the steps of: a) transmitting an ACK signal indicating a received packet includes no error or a NACK signal indicating the received packet includes error from a reception end to a transmission end, and performing automatic repeat request; b) obtaining reliability of the received packet when demodulating it at the reception end; and c) reporting from the reception end to the transmission end the reliability of the received packet utilizing the ACK/NACK signal by using not less than three levels.

    摘要： A multi-carrier CDMA radio transmitting method replicates each information symbol and disposes thus-obtained information symbols along a frequency axis, multiplies the thus-obtained information symbols with a spreading code along the frequency axis, spreads the information symbols into components of a plurality of subcarriers having different frequencies. The transmission rate of the information is changed by controlling the amount of information transmitted simultaneously by controlling the number of the information symbols to be used for spreading for the plurality of sub-carrier components for each user to which the information is to be transmitted.

    摘要： Even when a same C-RNTI is allocated to multiple mobile stations UE#A to UE#D in a phantom cell, a collision between the mobile stations UE#A to UE#D to which the same C-RNTI is allocated is avoided. A mobile communication method according to the present invention includes the steps of transmitting a first control signal including an identifier different from a C-RNTI to the mobile station UE#A through a PDCCH by a radio base station PhNB#10 managing a cell #10 formed by linking multiple small cells, transmitting a second control signal including the identifier to the mobile station UE through a PDCCH by a radio base station eNB#1 managing a cell #1 having a coverage area overlapping with a coverage area of the cell #10, and regarding the first control signal as valid by the mobile station UE, when it determines that the identifier included in the first control signal and the identifier included in the second control signal match each other.
