Solution Overview
Problem
In wireless communications systems, terminals are limited in the number of frequencies they can simultaneously measure, leading to a decrease in frequency measurement capability when a base station configures more frequencies than the terminal supports.
Innovation Solution
A method and terminal that receive frequency and priority information to determine and select the appropriate frequencies to measure, ensuring the number of measured frequencies matches the terminal's supported capacity, thereby enhancing frequency measurement capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a base station configures a terminal with more inter-frequency frequencies than the terminal supports, then the network can provide more comprehensive frequency measurement coverage, but the terminal's frequency measurement capability decreases because it cannot measure all configured frequencies
Solution Approach 1:
The patent changes the parameter of frequency selection by introducing priority information and terminal capability parameters. The network configures priority levels for different inter-frequency frequencies, and the terminal uses these priorities combined with its capability parameters to dynamically select which frequencies to measure, transforming a static limitation into a dynamic adaptive selection process
Solution Approach 2:
The patent makes the frequency measurement configuration dynamic by allowing the terminal to adjust its measurement set based on received priority information and its own capability parameters. Instead of a fixed configuration, the terminal can dynamically select which frequencies to measure within the configured set, enabling adaptability to changing network conditions and terminal capabilities
2Loss of information
If the terminal measures all configured inter-frequency frequencies, then complete frequency measurement information is obtained, but the terminal exceeds its supported measurement capacity
Solution Approach 1:
The patent extracts only the necessary subset of frequencies for measurement from the complete configured set. By using priority information and capability parameters, the terminal extracts and measures only those frequencies that are most important and within its capabilities, rather than attempting to measure all configured frequencies
Solution Approach 2:
The patent applies partial action by having the terminal measure only a portion of the configured frequencies - specifically those with highest priority that fit within terminal capabilities. This partial measurement approach is sufficient for network operation while respecting device limitations
3Ease of operation
If the terminal selects frequencies to measure without priority information, then the selection process is simple, but the frequency measurement capability and efficiency decrease
Solution Approach 1:
The patent applies preliminary action by having the network pre-configure priority information for different inter-frequency frequencies before the terminal performs measurements. This preliminary configuration enables the terminal to efficiently select frequencies based on pre-established priorities, avoiding complex real-time decision-making while maintaining high measurement efficiency

AI summary
The present application provides a method and a terminal for determining a frequency to be measured. The terminal receives frequency information about an inter-frequency measurement object and frequency priority information about the inter-frequency measurement object, and determines the number of at least one frequency for the received inter-frequency measurement object according to the frequency information, and when the number of the at least one frequency for the received inter-frequency measurement object is greater than the number of at least one frequency for an inter-frequency measurement object supported by the terminal, the terminal is capable of selecting, according to the frequency priority information, at least one frequency to be measured from the at least one frequency for the received inter-frequency measurement object, wherein the number of the at least one frequency to be measured is equal to the number of frequencies for the inter-frequency measurement object supported by the terminal.
