Abstract: Systems, methods, and computer-readable media for optimizing coverage for a cell site are provided. Cell sites are typically configured with antennas that emit a standard petal lobe pattern for a sector. The needs of the sector are not taken into account since a standard pattern is emitted for all antennas. The antennas may be adjusted at times to increase signal strength to particular regions but the pattern then returns to the standard petal pattern. Customized patterns may be created in order to optimize coverage for a sector. Sector needs may be taken into consideration such as object interference, geographical information, population data, and the like, in order to crate the customized pattern for a sector. The antenna may then emit the customized pattern for a predetermined length of time as a static pattern for that cell site.

Abstract: An inter-system interference estimation method is disclosed for both primary and secondary radio systems. In the case of a primary system (such as a GSM system), inter-system interference estimation is based on a comparison of cell level measurement statistics before and after secondary spectrum usage in neighboring cells. In the case of a secondary system (such as an LTE system), inter-system interference estimation is based on a measurement on secondary spectrum before starting transmission on the secondary spectrum. Based on both of the above mentioned inter-system inter-cell interference estimations, a cell-level decision on the secondary spectrum usage is made, and optimization of radio resource allocation inside the systems may be carried out.
