Multi-TRP DCI Linkage Under Cell DTX for Reliable UE Monitoring

The patent applies dynamics by making the monitoring behavior adaptive rather than static. The UE dynamically adjusts its monitoring strategy based on real-time linkage status determination between TRPs. When linkage is detected, the UE monitors only the active TRP; when linkage breaks, it monitors both TRPs. This dynamic adjustment resolves the contradiction by optimizing energy consumption while maintaining reception reliability through conditional monitoring.

The patent changes the monitoring parameter from continuous full monitoring to conditional monitoring based on linkage status. By determining linkage status through DTX cycle comparison and active duration checking, the system adjusts the monitoring scope parameter - monitoring one TRP when linked, both TRPs when not linked. This parameter change allows the system to achieve reliable reception only when necessary, reducing overall energy consumption.

The patent segments the linkage determination process into independent checks for each TRP's DTX status. Instead of evaluating the entire multi-TRP system complexity at once, the UE separately determines DTX status for each TRP using standardized parameters (DTX cycle, active duration). This segmentation simplifies the overall complexity by breaking down the linkage determination into manageable, independent steps that can be processed sequentially.

The patent implements feedback mechanisms where the UE continuously monitors DTX status changes and adjusts monitoring behavior accordingly. The linkage status determination provides feedback that triggers appropriate monitoring actions - monitoring one TRP when linked, both TRPs when not linked. This feedback loop manages complexity by using simple status information to drive adaptive behavior, avoiding the need for complex centralized control.

The patent applies periodic action through the DTX cycle mechanism itself, where TRPs alternate between active and inactive periods. The UE leverages this periodicity by determining linkage status based on whether candidates fall within active or inactive durations. When both TRPs are in inactive periods, the UE can safely reduce monitoring. This periodic action pattern allows the system to maintain reliability during necessary periods while consuming less energy during inactive periods.

The patent applies self-service by having the TRPs themselves manage their own transmission schedules through DTX cycles. The UE simply determines linkage status by comparing the periodic states of TRPs and adjusts monitoring accordingly. This self-service approach shifts the complexity of transmission scheduling to the TRPs themselves, allowing the UE to make simpler, rule-based monitoring decisions that reduce energy consumption while maintaining reliability.
