A radio transmission apparatus comprising: two or more first transmitting-side data processing sections which are placed at associated identical first transmitting-side sub-layers, respectively, of a data transmission path of respective individual logical channels of two or more logical channels, wherein each first transmitting-side data processing section is operable to send out data in such a way that first transmitting-side control information, to be transferred to a counterpart entity that is placed at a sub-layer of a receiving side that is identical with the first transmitting-side sub-layer, is added to data received from the respective individual logical channel; a second transmitting-side data processing section that is placed at a second transmitting-side sub-layer that is operable to mediate data transmission between a transport channel and the two or more logical channels, wherein the second transmitting-side data processing section is operable to send out data to the transport channel in such a way that data received from the two or more logical channels are integrated, and second transmitting-side control information, to be transferred to a counterpart entity that is placed at a sub-layer of the receiving side that is identical with the second transmitting-side sub-layer, is added; a data transmission section that is operable to receive data transmitted from the second transmitting-side data processing section via the transport channel and to transmit the received data by radio; and a control decision section that is operable to decide that it is the case that identical first transmitting-side control information is to be transmitted to two or more opposing entities which are placed at a sub-layer of the receiving side that is identical with the first transmitting-side sub-layer, wherein the second transmitting-side data processing section is operable to send out data to the transport channel in such a way that data received from the two or more logical channels are integrated, and, in a case in which identical first transmitting-side control information is to be transmitted to two or more opposing entities which are placed at a sub-layer of the receiving side that is identical with the first transmitting-side sub-layer, the second transmitting-side control information, to be treated in a counterpart entity which is placed at a sub-layer of the receiving side identical with the second transmitting-side sub-layer, the second transmitting-side control information being identical with the first transmitting-side control information in content, is added instead of the identical first transmitting-side control information. two or more first transmitting-side data processing sections which are placed at associated identical first transmitting-side sub-layers, respectively, of a data transmission path of respective individual logical channels of two or more logical channels, wherein each first transmitting-side data processing section is operable to send out data in such a way that first transmitting-side control information, to be transferred to a counterpart entity that is placed at a sub-layer of a receiving side that is identical with the first transmitting-side sub-layer, is added to data received from the respective individual logical channel; a second transmitting-side data processing section that is placed at a second transmitting-side sub-layer that is operable to mediate data transmission between a transport channel and the two or more logical channels, wherein the second transmitting-side data processing section is operable to send out data to the transport channel in such a way that data received from the two or more logical channels are integrated, and second transmitting-side control information, to be transferred to a counterpart entity that is placed at a sub-layer of the receiving side that is identical with the second transmitting-side sub-layer, is added; a data transmission section that is operable to receive data transmitted from the second transmitting-side data processing section via the transport channel and to transmit the received data by radio; and a control decision section that is operable to decide that it is the case that identical first transmitting-side control information is to be transmitted to two or more opposing entities which are placed at a sub-layer of the receiving side that is identical with the first transmitting-side sub-layer, wherein the second transmitting-side data processing section is operable to send out data to the transport channel in such a way that data received from the two or more logical channels are integrated, and, in a case in which identical first transmitting-side control information is to be transmitted to two or more opposing entities which are placed at a sub-layer of the receiving side that is identical with the first transmitting-side sub-layer, the second transmitting-side control information, to be treated in a counterpart entity which is placed at a sub-layer of the receiving side identical with the second transmitting-side sub-layer, the second transmitting-side control information being identical with the first transmitting-side control information in content, is added instead of the identical first transmitting-side control information.
