METHOD AND APPARATUS FOR GENERATING COVERAGE IN A CELLULAR NETWORK

摘要

The present invention relates to a sub-node (15, 25, 30), such as a repeater station or relay station, equipped with a multi-beam sub-node link antenna (16; 26A, 26B; 31, 32). The beams of the sub-node link antenna allow communication between the sub-node and at least two nodes (access points/base stations) 11A-B; 11A-E. The sub-node is further provided with at least one transmitting and receiving coverage antenna (17; 27; 37) to generate coverage in at least one geographical secondary coverage area a; a-c, and a control mechanism that selects one of the nodes to extend the geographical primary coverage area A-B; A-E of the node 11A-B; 11A-E to include the geographical secondary coverage area a; a-c of the sub-node (15, 25, 30). The invention is also related to a cellular communication network (10, 20, 90), and a method for generating coverage in a cellular communication network.
