Skipped Channel Buffering for 5G Beam Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in 5G NR, wireless devices face challenges in efficiently managing channel buffering for multiple beams, leading to increased memory requirements, processing needs, and power consumption due to the need to buffer all beams to receive data, which can be inefficient and power-intensive.
Innovation Solution
A method for selective skipping of channel buffering in wireless devices, where the device monitors beam scheduling and determines the probability of current channel transmissions being in a default beam, allowing it to skip buffering based on historical data analysis and signal quality thresholds, thereby reducing power consumption and memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device buffers all multiple beams to receive data, then the reliability of data reception is improved, but the memory requirements and power consumption increase
Solution Approach 1:
The patent segments the beam receiving process into two parts: the default beam is monitored and processed, while other beams are skipped and not buffered. This segmentation allows the device to focus resources on the most critical beam (default beam) while reducing overall buffering requirements and power consumption.
Solution Approach 2:
The patent extracts the default beam from the set of multiple beams and gives it special treatment. The default beam is the only beam that requires buffering and detailed processing, while other beams are excluded from buffering operations, thereby reducing memory and power requirements while maintaining reception reliability.
2Reliability
If the wireless device buffers all multiple beams to receive data, then the data reception completeness is improved, but the processing complexity increases
Solution Approach 1:
The patent segments the beam processing workload by separating the default beam from other beams. Only the default beam undergoes complex buffering and processing operations, while other beams are handled more simply by skipping buffering, thereby reducing overall processing complexity.
Solution Approach 2:
The patent extracts the default beam from the multiple beams and applies different processing rules. The default beam receives full processing attention, while other beams are excluded from complex processing operations, reducing the overall computational burden on the device.
3Reliability
If the wireless device buffers all multiple beams to receive data, then the data reception reliability is improved, but the memory requirements increase
Solution Approach 1:
The patent segments the buffering requirement by applying it only to the default beam while excluding other beams from buffering operations. This segmentation significantly reduces the total memory space required while maintaining reliable data reception through the default beam.
Solution Approach 2:
The patent extracts the default beam from the set of multiple beams and applies buffering only to this extracted beam. Other beams are excluded from buffering operations, thereby reducing memory requirements while preserving reception reliability through the default beam.
4Measurement precision
If the wireless device monitors and buffers multiple beams, then the accuracy of beam selection is improved, but the power consumption increases
Solution Approach 1:
The patent segments the beam monitoring process by focusing detailed monitoring and analysis only on the default beam, while other beams receive minimal or no monitoring. This segmentation maintains accurate beam selection through the default beam while reducing overall power consumption.
