Beam-Swept Trigger Signaling for Collision-Reduced Uplink Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The surge in uplink data transmission due to a large number of terminals limits the uplink capacity in network systems, particularly in scenarios where network-side data reporting is expected from terminals in a specific area.
Innovation Solution
Implementing a communication method that utilizes beam sweeping and time/resource differentiation for data reporting, where terminals receive trigger commands at different times and select specific uplink resources to report data, thereby improving uplink capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals in a specific area report data simultaneously in response to a trigger command, then the network side can perform comprehensive analysis and statistics, but the uplink data transmission amount surges and uplink capacity is limited
Solution Approach 1:
The patent segments the simultaneous data reporting process into multiple time intervals and uplink resources. Terminals are divided into different groups that report data at different times or use different uplink resources, transforming a concentrated surge into distributed transmissions across multiple dimensions (time, frequency, code resources).
Solution Approach 2:
The patent introduces additional dimensions for resource allocation beyond simple time division. By utilizing multiple uplink resources including frequency resources, code resources, and time resources simultaneously, the system creates a multi-dimensional resource space that accommodates more terminals reporting data without overwhelming the uplink capacity in any single dimension.
2Device complexity
If all terminals use the same uplink resource to report data, then resource allocation is simple, but data reporting collisions occur and uplink capacity is reduced
Solution Approach 1:
The patent segments the single uplink resource into multiple distinct uplink resources (frequency resources, code resources, time resources). Each terminal or terminal group is assigned to a specific segment, eliminating collisions by ensuring that multiple terminals do not occupy the same resource simultaneously.
Solution Approach 2:
The patent implements dynamic resource allocation where terminals can select different uplink resources based on their specific conditions, channel quality, and network requirements. This dynamic selection mechanism allows the system to adapt to changing conditions and optimize resource utilization while maintaining low collision probability.
Data Source
AI summary
Provided are a communication method and a communication apparatus, a terminal, and a network device. The method includes: a terminal receives a trigger command from a network device, and transmits data to the network device, the trigger command is used to trigger the terminal to report the data. The trigger command is transmitted based on a beam sweeping manner, and/or the data is transmitted based on a first manner and/or a second manner. The first mode is that, after receiving the trigger command, the terminal selects a first time interval from a plurality of time intervals, and transmits the data after a delay of the first time interval. The second mode is that, after receiving the trigger command, the terminal selects a first uplink resource from a plurality of uplink resources, and transmits the data by using the first uplink resource.
