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.
