Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face delays in random access procedures due to inefficient use of uplink resources, particularly in scenarios involving subband full duplex technology.
Innovation Solution
The implementation of a wireless communication method that allows a terminal device to perform random access using specific first information related to a first uplink subband or first terminal, optimizing resource selection and reducing delays through enhanced RACH configurations and power adjustment parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional random access procedures are used, then device compatibility is maintained, but random access delay increases
Solution Approach 1:
The patent segments uplink resources into multiple uplink subbands, each with dedicated RACH resources. This segmentation allows terminals to select from multiple subbands for random access, increasing resource availability and reducing access delay while maintaining compatibility through selective usage of segmented resources.
Solution Approach 2:
The patent introduces frequency domain dimensioning by creating multiple uplink subbands with different RACH resource configurations. Terminals can perform random access on different frequency subbands, adding a frequency dimension to the random access process that increases resource availability and reduces contention delay.
2Quantity of substance
If multiple uplink subbands are configured for random access, then resource availability increases, but device complexity increases
Solution Approach 1:
The network device pre-configures multiple uplink subbands with RACH resources before random access occurs. Terminals receive and store these configurations in advance, allowing them to quickly select from pre-prepared resources during random access without real-time computation, thus increasing resource availability while managing device complexity.
Solution Approach 2:
The patent changes the parameter of uplink frequency resources by configuring multiple uplink subbands with different frequency allocations and RACH parameters. This parameter diversification increases resource availability for random access while the structured configuration approach manages the complexity through standardized parameter sets.
