NON-COLLOCATED SCELL SELECTION FOR CARRIER AGGREGATION

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.
