Abstract
Current approaches to radio link control (RLC) data forwarding with no end-to-end RLC entities between a given UE and IAB donor node lack proper buffer management. In various examples, the premature deletion of transmitted PDCP PDUs is avoided. Various embodiments also address buffer size control, for example end-to-end flow control, hot-by-hop flow control, explicit and implicit flow control options are described. Content of flow control messages, transmitter actions at the reception of flow control, and triggers for flow controls are also described herein.
