Destination ID-Based Initial Beam-Pairing Reference Signals

The patent applies preliminary action by configuring UEs with destination IDs before the beam-pairing process begins. These destination IDs are pre-assigned to specific UEs, allowing them to filter reference signals before processing. When a UE receives an IBP-RS, it checks whether the destination ID embedded in the signal matches its own identifier. Only matching UEs proceed to respond, preventing non-target UEs from consuming energy on unnecessary beam-pairing operations. This pre-filtering mechanism resolves the contradiction by ensuring reliable beam association only for intended recipients while eliminating wasteful energy consumption from irrelevant responses.

The patent implements universality by integrating destination ID functionality into existing UE identification mechanisms. Rather than creating entirely new filtering hardware or protocols, the system leverages existing UE identity management capabilities. The destination ID is embedded within standard reference signal structures, and UEs use their existing identity comparison logic to perform filtering. This multi-functional approach reduces energy consumption through intelligent filtering while minimizing additional system complexity by reusing established identification and signaling frameworks.

The patent applies local quality by making the IBP-RS transmission targeted and specific rather than broadcast to all UEs. Each IBP-RS is configured with a destination ID that corresponds to a specific intended recipient UE. This creates localized, personalized reference signal instances for different UEs rather than a single universal signal. The destination ID acts as a local filter that enables flexible unicast link establishment with specific UEs while preventing other UEs from responding, thus maintaining adaptability for different communication scenarios while eliminating wasteful radio resource utilization from irrelevant responses.
