Abstract
Embodiments include methods by a user equipment (UE) configured for dual connectivity with a master node providing a master cell group that includes a primary serving cell (PCell) and with a secondary node providing a secondary cell group that includes a primary secondary cell (PSCell). Such methods include detecting a radio link problem associated with a first serving cell, wherein first serving cell is the PCell or the PSCell. Such methods include, in response to detecting the radio link problem, for each of the UE's split radio bearers that has a primary path set to a first cell group that includes the first serving cell, performing a recovery procedure such that all uplink data transmission for the split radio bearer occurs only via a secondary path that does not include the first serving cell. Embodiments also include complementary methods performed by network nodes, as well as UEs and network nodes.
