Abstract
Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. More specifically, in some embodiments, a statistics-assisted sCell selection process is utilized for sCell selection. This statistics-assisted sCell selection process improves the efficiency of sCell selection, particularly where there are multiple candidate sCells on multiple carrier frequencies.
Claims26
A method of operating a network node to provide secondary cell, sCell, selection, comprising:
- collecting statistics indicative of correlation between one or more source cells and one or more successful and/or non-successful sCells for each of the one or more source cells;
- and
- performing sCell selection based on the statistics.
A network node for providing secondary cell, sCell, selection, comprising:
- a processor;
- and
- memory containing instructions executable by the processor, whereby the network node is operative to:
- collect statistics indicative of correlation between one or more source cells and one or more successful and/or non-successful sCells for each of the one or more source cells;
- and
- perform sCell selection based on the statistics.
