    Abstract: A wireless station of a radio access network receives a reselection priority value of a frequency band used when the wireless station is an E-UTRA-NR Dual Connectivity (EN-DC) anchor. The wireless station broadcasts an intra-frequency system information block (SIB) that includes a first Cell Reselection Priority information element (IE) and a first Anchor-cell Reselection Priority IE, wherein the first Anchor-cell Reselection Priority IE includes the reselection priority value of the frequency band used by the wireless station. The wireless station also broadcast an inter-frequency SIB that includes a second Cell Reselection Priority IE and a second Anchor-cell Reselection Priority IE, wherein the second Anchor-cell Reselection Priority IE includes another reselection priority value of another frequency band for another EN-DC anchor. Use of additional anchor-cell priorities enable EN-DC-capable end devices to camp on an anchor cell even when a non-anchor cell has a higher conventional priority than the anchor cell.

    Abstract: Systems and methods described herein enable optimizing carrier aggregation over a dual-connectivity bearer. A wireless station determines a buffer size for an end device connected to the wireless station via a wireless communication interface. The buffer size reflects a service requirement for the end device. The wireless station determines, for the end device and based on the buffer size, an optimal carrier aggregation combination to satisfy a service requirement for the end device, wherein the optimal carrier aggregation combination is selected from a dynamic list of component carriers for different radio access technology (RAT) types that are available to end devices serviced by the wireless station; and sends, to the end device, instructions to implement the carrier aggregation combination.
