Solution Overview
Problem
Current wireless communication systems, particularly in 5G networks, face challenges in efficiently managing system information transmission windows, limiting flexibility in scheduling and increasing power consumption for user equipment (UE) in multi-beam scenarios.
Innovation Solution
The method involves configuring and transmitting information regarding synchronization signal (SS) blocks for system information grants and paging downlink control information, allowing user equipment (UE) to monitor for transmissions within specified windows, enhancing scheduling flexibility and reducing power consumption by providing precise monitoring windows for system information and paging messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If system information transmission windows are configured without precise timing control, then base stations can simplify scheduling, but user equipment power consumption increases due to extended monitoring requirements
Solution Approach 1:
The patent changes the timing parameter by introducing a specific window offset parameter (K) that defines the precise start time of the system information transmission window relative to the synchronization signal block. This parameter control enables UEs to accurately determine when to monitor, reducing unnecessary monitoring and power consumption while maintaining simplified scheduling for base stations.
Solution Approach 2:
The patent applies preliminary action by providing UE with advance information about the window offset parameter and monitoring configuration before the actual system information transmission. This allows UE to pre-calculate the exact monitoring window timing, ensuring it only activates receivers during necessary periods, thus reducing power consumption while keeping base station scheduling straightforward.
2Reliability
If monitoring windows for system information are extended to ensure reliable reception, then communication reliability improves, but user equipment power consumption increases
Solution Approach 1:
The patent introduces a window offset parameter (K) that precisely defines the monitoring window timing. By optimizing this parameter, the system ensures reliable reception within a compressed time window, preventing UEs from extending monitoring unnecessarily and thus reducing power consumption while maintaining reliability.
Solution Approach 2:
The patent implements periodic action by configuring specific monitoring occasions within a periodic framework. UEs monitor for system information grants only at predetermined periodic intervals defined by the window offset, rather than continuously or over extended periods, ensuring reliable reception while minimizing power consumption through targeted periodic monitoring.
3Use of energy by moving object
If precise monitoring windows are configured for system information transmissions, then user equipment power consumption reduces, but scheduling flexibility for base stations decreases
Solution Approach 1:
The patent uses parameter changes by introducing configurable window offset parameters that can be adjusted based on network conditions. This allows base stations to maintain scheduling flexibility through parameter adjustment while UEs benefit from precise monitoring windows that reduce power consumption. The parameter-based approach enables dynamic adaptation without sacrificing either flexibility or energy efficiency.
Solution Approach 2:
The patent applies dynamics by making the monitoring window configuration dynamic rather than fixed. Base stations can adjust the window offset parameter (K) and monitoring occasion timing based on current network conditions and traffic patterns, maintaining scheduling flexibility while ensuring UEs have precise monitoring windows to minimize power consumption. This dynamic configuration resolves the contradiction between precision and adaptability.
4Use of energy by moving object
If system information transmission windows are compressed to reduce monitoring time, then user equipment power consumption decreases, but the risk of transmission conflicts increases
Solution Approach 1:
The patent applies segmentation by dividing the system information transmission into structured segments with defined windows and offsets. By segmenting the transmission timing into specific monitored occasions separated by defined intervals, the system compresses monitoring time for UEs (reducing power consumption) while maintaining sufficient separation between transmissions to avoid conflicts. The window offset parameter creates clear temporal boundaries that prevent overlapping transmissions.
