COMMUNICATION BETWEEN A RADIO EQUIPMENT CONTROL NODE AND MULTIPLE REMOTE RADIO EQUIPMENT NODES

摘要

An interface, apparatus, and method are described for communication between a radio control (REC) node and first and second radio equipment (RE) nodes in a radio base station that transceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the first RE node by a first transmission link, and the second RE node coupled to the first RE by a second transmission link. Both control information and user information intended for communication between the REC node and the first RE node and the REC and the second RE node are conveyed over the first transmission link. The first RE node also conveys information between the REC and second RE node. Many advantageous features are described.
