Solution Overview
Problem
In the 5G system, the Multi-beam scenario lacks a scheme for measurement in the idle state, leading to incomplete communication and unreliable network connectivity due to the inability to perform cell selection and reselection.
Innovation Solution
A method and terminal device that acquire measurement configuration information for multiple beams, measure their quality, and perform cell selection or reselection based on the measurement results, ensuring the terminal camps in an appropriate cell for reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-beam scenario is introduced in 5G system, then communication capacity and coverage are improved, but measurement scheme in idle state becomes unavailable and cell selection/reselection cannot be performed
Solution Approach 1:
The patent segments the beam measurement process by introducing a measurement configuration parameter that specifies the number of beams to be measured. This segmentation allows the system to handle multi-beam scenarios by breaking down the measurement task into manageable units (specific number of beams) while maintaining the ability to perform cell selection and reselection in idle state.
Solution Approach 2:
The patent changes the parameter of beam measurement by introducing a configurable measurement configuration parameter that defines the number of beams to measure. This parameter change enables the system to adapt to multi-beam scenarios while preserving idle state measurement capabilities, thus resolving the contradiction between improved communication capacity and maintained reliability.
2Reliability
If beam measurement is performed in idle state, then cell selection and reselection can be achieved, but measurement configuration and control complexity increases
Solution Approach 1:
The patent applies self-service by allowing the terminal to autonomously perform beam measurements based on the received measurement configuration parameter. The terminal independently determines which beams to measure and performs the measurements without requiring complex network control, thus achieving reliable cell selection while minimizing measurement configuration complexity.
Solution Approach 2:
The patent extracts the measurement configuration parameter from complex network control and provides it to the terminal in a simplified form. This extraction reduces the measurement configuration complexity at the network side while enabling the terminal to perform autonomous beam measurements for reliable cell selection and reselection.

AI summary
A terminal and a computer readable storage medium are provided. The computer readable medium stores a program. When a processor executes the program, the processor implements a method of cell selection /cell reselection, the method includes acquiring measurement configuration information of beams, wherein the measurement configuration information includes the number of beams measured by a terminal; measuring the beams based on the measurement configuration information to acquire a measurement result of each beam; performing, based on the measurement result of each beam, the cell selection /cell reselection of a cell in which the terminal camps when the terminal is in an idle state.
