Method for establishing differentiated data radio bearer connections in relay networks based on relay node hop position within the network topology.

Patentradars sammanfattning

The invention relates to connection establishment procedures in relay networks, wherein a relay node's network connectivity is determined by its hierarchical position. When a relay node operates as a non-first-hop node, a data radio bearer (DRB) is established without a user plane tunnel; conversely, first-hop relay nodes receive both a DRB and an associated user plane tunnel. This differentiated approach optimizes resource allocation and signaling overhead based on the relay node's role within the multi-hop relay architecture.
