Random Access Resource Selection for Variable Uplink Data Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing random access procedures in communications technologies, such as the 2-step and 4-step random access procedures, are unable to support the transmission of various types of uplink data of different sizes effectively.
Innovation Solution
A method for selecting a random access request resource is implemented, where configuration information is obtained and used to select a resource corresponding to a specific data size range, allowing for the transmission of uplink data of different sizes by a terminal and network device, including the selection of time-frequency resources, downlink signals, cells, uplink carriers, and code resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single random access request resource is used for all uplink data, then the device complexity is reduced, but the adaptability to different data sizes deteriorates
Solution Approach 1:
The patent segments the random access request resources into multiple groups, where each group corresponds to a specific data size range. The network device configures multiple data size ranges (e.g., first data size range, second data size range) with different random access request resources for each range. This segmentation allows the system to adapt to different uplink data sizes while maintaining organized resource management.
Solution Approach 2:
Different random access request resources are assigned to different data size ranges, creating local optimization for each data size category. The terminal selects resources based on the local characteristics of its data size, ensuring that each data type uses the most appropriate resource configuration rather than a one-size-fits-all approach.
2Adaptability or versatility
If multiple random access request resources are configured for different data sizes, then the adaptability improves, but the ease of operation deteriorates
Solution Approach 1:
The network device performs preliminary configuration by pre-defining multiple data size ranges and assigning specific random access request resources to each range before the terminal needs to transmit data. This preliminary action simplifies the terminal's operation, as it only needs to determine its data size and select from pre-configured options rather than making complex decisions in real-time.
Solution Approach 2:
The system dynamically adapts to different data sizes by allowing the terminal to select appropriate resources based on its current data transmission needs. The resource selection is dynamic and data-dependent, enabling the terminal to efficiently choose the most suitable random access request resource for its specific uplink data size.
3Productivity
If random access procedure is simplified, then the productivity is improved, but the measurement precision of data size requirements deteriorates
Solution Approach 1:
The patent introduces data size range as a key parameter for resource selection. By changing the parameter from a single resource configuration to multiple configurations based on data size ranges, the system achieves both simplified operation (through clear range-based classification) and precise matching (by selecting resources specifically suited for each data size category).

AI summary
This disclosure discloses a method for selecting a random access request resource, a terminal, and a network device. The method is applied to the terminal and includes: obtaining configuration information for a random access procedure used for transmitting uplink data, where the configuration information is used for at least one data size range and a random access request resource corresponding to each data size range; and selecting, according to the configuration information, a random access request resource corresponding to a data size range of uplink data.
