Radio communication system, communication apparatus, method for controlling simultaneous transmission from multiple base stations, and non-transitory computer readable medium
First Claim
1. A radio communication system comprising:
- first and second base stations being capable of wirelessly transmitting packet data addressed to a mobile station;
a first gateway unit configured to transmit the packet data to the first base station;
a second gateway unit configured to communicate with the first base station, the second base station, and the first gateway unit; and
a control unit configured to signal information related to a communication path configuration to transfer the packet data, whereinsetup of a first communication path, to transmit the packet data to the first base station from the first gateway unit through the second gateway unit, is performed based on first packet data communication information signaled by the control unit, andsetup of a second communication path, to transmit the packet data to the second base station from the second gateway unit, is performed based on at least one of the first packet data communication information, second packet data communication information signaled by the control unit to the first base station, and third packet data communication information signaled by the control unit to the second gateway unit.

Abstract
A first GW function block (6) transmits packet data to a first base station (1). A second GW function block (7) is able to communicate with the first base station (1), a second base station (2), and the first GW function block (6). A control function block (5) signals information related to a communication path configuration to transfer the packet data. Setup of a communication path, to transmit the packet data to the base station (1) from the GW function block (6) through the GW function block (7), is performed based on first packet data communication information signaled by the control function block (5). Setup of a communication path, to transmit the packet data to the base station (2) from the GW function block (7), is performed based on at least one of the first packet data communication information, second packet data communication information signaled by the control function block (5) to the base station (1), and third packet data communication information signaled by the control function block (5) to the GW function block (7).
