Terminal Capability Reporting for Codebook Parameter Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately obtaining and adjusting terminal operations based on complete radio access capability information, leading to inefficient network-resource utilization.
Innovation Solution
A terminal equipped with a receiving unit to process capability requests, a control unit to filter and configure necessary capability reporting parameters, and a transmitting unit to send relevant information to the base station, ensuring only necessary capability data is reported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal reports all capability parameters, then the network obtains complete terminal capability information, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent extracts and reports only the necessary capability parameters based on the network's specific requests. The terminal receives a capability enquiry message from the network, identifies which capability parameters are being requested, and reports only those specific parameters rather than all possible capabilities, thereby reducing signaling overhead while providing complete information for the network's needs
Solution Approach 2:
The patent segments the terminal capability reporting into multiple stages: first receiving a capability enquiry message from the network, then identifying requested parameters, and finally reporting only those specific parameters. This segmentation allows the terminal to provide complete information when needed while avoiding unnecessary signaling in other scenarios
2Reliability
If the terminal reports all capability parameters, then the network has complete information for operation adjustment, but the message size and transmission overhead increase
Solution Approach 1:
The patent extracts only the specific capability parameters that the network has requested in its enquiry message. The terminal identifies the requested parameters from the message and reports only those, ensuring the network receives sufficient information for accurate operation adjustment without the overhead of transmitting unnecessary capability data
Solution Approach 2:
The patent applies partial action by reporting only the necessary subset of capability parameters rather than all possible parameters. The terminal determines which parameters are needed based on the network's enquiry and reports exactly that portion, avoiding both under-reporting (which would harm reliability) and over-reporting (which would increase message size)
3Adaptability or versatility
If the terminal includes additional codebook parameters, then the network can better adjust terminal operations, but the reporting message becomes larger and more complex
Solution Approach 1:
The patent makes the capability reporting dynamic by having the terminal adapt its response based on the network's specific needs. The terminal receives an enquiry message, dynamically determines which capability parameters are requested, and adjusts its report to include only those parameters. This dynamic approach allows high adaptability when the network needs detailed information while keeping the message simple when fewer parameters are required
Data Source
AI summary
A terminal includes a receiving unit that receives, from a base station, a message that requests a report on terminal capability; a control unit that includes information for reporting a parameter for a codebook per band and information for reporting a parameter for a codebook per band combination in a message for reporting the terminal capability, the information for reporting the parameter for the codebook per band and the information for reporting the parameter for the codebook per band combination being included based on information for specifying a type of a codebook included in the message that requests the report on the terminal capability; and a transmitting unit that transmits the message for reporting the terminal capability to the base station.
