PILOT SIGNAL ALLOCATION METHOD AND APPARATUS FOR MULTI-USER WIRELESS SYSTEMS |
摘要 |
<p>A construction is provided for uplink pilot signals in a cellular network. Three sets of pilot signals are defined, having orthogonality properties that lead to reduced inter-cell interference. In example embodiments, the network has a reuse factor of 3 for pilot signals, with sets U, V, and W of pilot signals assigned to cells in respective reuse classes. The pilots of each set form an orthogonal basis. Some pilots of each class, i.e. those which will generally be assigned to mobile stations near the cell edges, will also form an orthogonal basis with some pilots of each of the other classes.</p> |
