Abstract: A communication apparatus 101 of the disclosure herein employing a communication standard different from that of a base station 103 having a baseband unit 105 and at least one remote radio unit 107 connected to the baseband unit via a wired line, the communication apparatus 101 having an interface unit connected to the remote radio unit 107 and a controller for controlling the interface unit to transmit, via the wired line 109, communication-related information of the communication apparatus 101 to at least one other communication apparatus 101 connected to the remote radio unit 107.

Abstract: Provided are a radio communication system, a radio communication apparatus, a radio communication terminal, and a communication method those being capable of facilitating handover of a dual terminal to a base station corresponding to the other communication scheme, thereby improving frequency utilization efficiency of the entire radio communication system that employs a plurality of communication schemes. Specifically, a first radio communication apparatus (1) is provided with a transmission unit (100) for transmitting information (106) about a backbone line shared with a second radio communication apparatus (2). A first radio communication terminal (3) and a second radio communication terminal (4) are provided with a selection unit (32) and a selection unit (41), respectively, for selecting a radio communication apparatus to connect based on the information (106) received.

Abstract: An IF unit to an RF unit generate a packet signal containing a control signal and a data signal and transmits the thus generated packet signal. A radio control unit performs a first retransmission control or a second retransmission control on the packet signal transmitted. The radio control unit causes the IF unit to the RF unit to have first control information for the first retransmission control contained in the control signal and have second control information for the second retransmission control contained in the data signal.
