摘要： A method for selecting one or more secondary cells, SCells for supporting communication with a user equipment, UE, by carrier aggregation, CA. The one or more SCells is/are selected from a set of SCell candidates available for an access node. The method includes estimating a probability that the UE connected to a primary cell, PCell, of the access node is in coverage of an SCell in the set of candidates, predicting available resources for the SCell, calculating a CA value for the SCell based on the estimated probability, an estimated spectral efficiency and the predicted available resources, and calculating a CA value for each SCell of the set of SCell candidates, ranking the SCells of the set of SCell candidates based on their calculated CA values, and selecting one or more SCells for providing CA with the UE based on the ranking.

摘要： A method and apparatus are disclosed for non-collocated SCell selection for NR CA. In one embodiment, a network node is configured to estimate a first throughput for the WD at a first candidate secondary cell, the estimated first throughput being based on a measured inter-network node delay between the network node and a first network node supporting the first candidate secondary cell, the network node supporting a primary cell; and determine whether to select the first candidate secondary cell for the WD based on the first estimated throughput. In another embodiment, a network node is configured to determine an average amount of time resources associated with a Hybrid Automatic Repeat reQuest, HARQ, process exhaustion experienced by WDs connected to the first candidate secondary cell and primary cells with an inter-network node delay, d; and report the average amount.
