Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DRX configurations in multi-beam operations are inefficient due to the need for conventional reconfiguration procedures when switching serving beams, leading to unnecessary resource usage and potential false alarms in power saving control information transmission.
Innovation Solution
Configure each transmission beam with a unique scrambling identifier, allowing efficient switching of control information transmission and reception by associating specific scrambling identifiers with each beam, thereby optimizing resource usage and reducing unnecessary transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional reconfiguration procedures are used for serving beam switching in multi-beam operations, then reliability of control information transmission is improved, but device complexity and resource usage increase
Solution Approach 1:
The patent segments the DRX configuration by associating different scrambling identifiers with different transmission beams. Each beam has its own dedicated scrambling identifier, allowing the receiving device to efficiently identify and process control information from specific beams without requiring complex reconfiguration procedures when switching between beams.
Solution Approach 2:
The patent performs preliminary configuration by pre-associating scrambling identifiers with transmission beams before actual data transmission. This preliminary setup enables the receiving device to immediately recognize control information from the current serving beam without requiring reconfiguration when beam switching occurs, thus reducing complexity while maintaining reliability.
2Reliability
If conventional reconfiguration procedures are used for serving beam switching, then transmission reliability is improved, but transmission time is increased
Solution Approach 1:
The patent performs preliminary configuration by pre-associating scrambling identifiers with transmission beams before actual data transmission. This preliminary setup enables the receiving device to immediately recognize control information from the current serving beam without requiring reconfiguration when beam switching occurs, thus reducing complexity while maintaining reliability.
3Productivity
If multiple scrambling identifiers are configured for different transmission beams, then resource usage efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the DRX configuration by associating different scrambling identifiers with different transmission beams. Each beam has its own dedicated scrambling identifier, allowing the receiving device to efficiently identify and process control information from specific beams without requiring complex reconfiguration procedures when switching between beams.
Solution Approach 2:
The receiving device autonomously determines which scrambling identifier to use based on the current serving beam identification. This self-service mechanism eliminates the need for complex network-side reconfiguration procedures, as the device can independently select the appropriate scrambling identifier from its configured set, thereby improving resource efficiency without proportionally increasing complexity.
4Ease of operation
If conventional DRX configuration is used in multi-beam operations, then ease of operation is maintained, but false alarms in power saving control information increase
Solution Approach 1:
The patent segments the DRX configuration by associating different scrambling identifiers with different transmission beams. Each beam has its own dedicated scrambling identifier, allowing the receiving device to efficiently identify and process control information from specific beams without requiring complex reconfiguration procedures when switching between beams.
Solution Approach 2:
The scrambling identifier acts as an intermediary between the transmission beam and the control information. By using beam-specific scrambling identifiers, the system enables the receiving device to accurately identify control information intended for the current serving beam, thereby reducing false alarms while maintaining ease of operation through autonomous identifier selection.
