Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in 5G NR, face inefficiencies in power consumption and resource utilization due to the need for UEs to monitor and transmit on multiple beams without optimal selection, leading to unnecessary power consumption and resource waste.
Innovation Solution
A method and apparatus for UEs and base stations to configure and monitor multiple beams with different time and frequency periods within a monitoring window, allowing UEs to report on suitable and less suitable beams, enabling the base station to adjust transmissions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs monitor multiple beams without optimal selection, then communication reliability is improved through beam diversity, but power consumption increases due to continuous monitoring of all beams
Solution Approach 1:
The patent implements dynamic search space configuration where the UE selectively monitors beams based on real-time channel conditions and feedback mechanisms. The monitoring configuration is dynamically adjusted rather than static, allowing the UE to adapt its beam monitoring behavior to current network conditions, thereby reducing power consumption while maintaining communication reliability through optimal beam selection.
Solution Approach 2:
The patent employs feedback mechanisms where the UE reports beam measurement results and communication quality metrics back to the base station. This feedback loop enables the base station to adjust transmission parameters and select optimal beams, while the UE can stop monitoring beams that are confirmed to be non-optimal, thus reducing power consumption without sacrificing reliability.
2Productivity
If UEs monitor all beams within monitoring window, then resource utilization is improved through comprehensive beam assessment, but time consumption increases due to extended monitoring duration
Solution Approach 1:
The patent applies partial action by having the UE monitor only a subset of beams within the monitoring window rather than all beams. The UE selects and monitors beams based on priority, channel conditions, or historical performance, thereby reducing time consumption while still achieving adequate resource utilization through strategic beam selection rather than exhaustive monitoring.
Solution Approach 2:
The patent implements preliminary action through pre-configuration of beam monitoring parameters and priority lists. The base station pre-configures which beams should be monitored first or with higher priority, allowing the UE to efficiently allocate its monitoring time to the most promising beams, thus reducing overall time consumption while maintaining effective resource utilization.
3Reliability
If base station transmits on all configured beams, then coverage and reliability are improved through multi-beam transmission, but resource waste increases due to transmission on unsuitable beams
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmission parameters based on beam performance metrics. The base station modifies transmission parameters such as power level, modulation scheme, or beam direction based on real-time feedback from beam measurements and channel conditions, thereby avoiding resource waste on unsuitable beams while maintaining reliability through optimized transmission parameters on suitable beams.
Solution Approach 2:
The patent employs feedback mechanisms where the UE reports beam measurement results and communication quality metrics back to the base station. This feedback loop enables the base station to adjust transmission parameters and select optimal beams, avoiding transmission on unsuitable beams and thus reducing resource waste while maintaining communication reliability.
Data Source
AI summary
The present disclosure relates to transmitting and receiving improved monitoring reports. A base station can configure a user equipment (UE) to monitor a channel/signal on multiple beams. The base station can transmit the multiple beams to the UE, which are at different time periods in a monitoring window. The UE can then monitor the multiple beams within the monitoring window and determine a monitoring report. The UE can then transmit the monitoring report to the base station, wherein the monitoring report indicates a subset of multiple beams as being more or less suitable for communication. The base station can also indicate that it will stop transmitting one or more beams and then stop transmitting the beams. If the UE does not send the report, the base station can continue to transmit the multiple beams.
