In an approach to RLC channel management for low memory 5G devices, responsive to detecting a memory overload in an RLC layer of a 5G user equipment, whether slices of a plurality of slices are merger candidates is determined. Responsive to determining that the slices are merger candidates, whether any merger candidates can share a transportation logical entity is determined, where merger candidates can share the transportation logical entity if performance and quality parameters are within predetermined limits. The merger candidates that can share the transportation logical entity are marked as allowed candidates. Responsive to determining that at least one allowed candidate has a workload that is below a predetermined threshold, the allowed candidates are merged into merged flows.
