Method and apparatus for generating coverage in a cellular network
First Claim
1. A sub-node configured to be used in a cellular communication network, said sub-node comprising:
- at least one transmitting and receiving coverage antenna to generate coverage in at least one geographical secondary coverage area, said sub-node configured to be in communication with a node, generating coverage in a geographical primary coverage area, to extend the coverage of said node to include said at least one geographical secondary coverage area;
at least one link antenna configured to provide communication with a plurality of nodes;
means to divide the at least one geographical secondary coverage area of said at least one sub-node into at least two parts dependent on measured parameters, wherein said parameters include at least the traffic load in the cellular communication network; and
,a control mechanism, responsive to said measured parameters, configured to select a first node and a second node from said plurality of nodes to extend coverage of each of said selected first node and second node to include at least one part of said divided geographical secondary coverage area.

Abstract
A sub-node, such as a repeater station or relay station, equipped with a multi-beam sub-node link antenna. 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 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. The invention is also related to a cellular communication network, and a method for generating coverage in a cellular communication network.
