Abstract: A method and system to help facilitate communication between a user equipment device (UE) and an access node that is serving the UE, in a scenario where a bearer is configured for the UE, the bearer having a defined set of quality-of-service (QoS) requirements for communication of user-plane data on the bearer. When wireless coverage of the UE from the access node is threshold poor, the access node and a supporting core network could interwork to loosen the set of QoS requirements of the bearer in an effort to avoid loss of the bearer. And upon loosening of the set of QoS requirements, the access node could invoke Packet Data Convergence Protocol (PDCP) duplication for the communication between the UE and the access node on the bearer, to help improve quality of the communication between the UE and the access node in presence of the threshold poor wireless coverage.
