| 摘要 | Systems and methods for Secondary Cell (sCell) selection for wireless devices (22) operating according to a carrier aggregation scheme in a cellular communications network (14) are disclosed. In one embodiment, a network node (16) in the cellular communications network (14) obtains geographic 5 signatures for a number of candidate sCells (24). The geographic signatures include a geographic signature for each candidate sCell (24) that approximates a coverage area of the candidate sCell (24). The network node (16) obtains position information for a wireless device (22) and then selects one or more sCells (24) for the wireless device (22) from the candidate sCells (24) based on 10 the geographic signatures for the candidate sCells (24) and the position information for the wireless device (22). The network node (16) then configures the selected sCell(s) (24) for use by the wireless device (22) according to a carrier aggregation scheme. Using this process, sCell selection is performed, in some examples, without measurement gaps and without disabling an s-Measure 15 parameter. | ||||||
