Terminal Device Measurement Gap Configuration for Reference Signal Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, terminal devices can only measure reference signals in one frequency domain using a single measurement gap, leading to incomplete measurement of signals that occupy different time domain resources, resulting in incomplete signal information acquisition.
Innovation Solution
A communication method and apparatus that utilize multiple measurement gap configurations and corresponding reference signal groups, where reference signals occupying the same time domain resource are grouped together, allowing for simultaneous measurement across multiple gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a terminal device uses only a single measurement gap configuration to measure reference signals, then the device complexity is reduced, but the measurement precision is insufficient because reference signals occupying different time domain resources cannot be completely measured
Solution Approach 1:
The patent divides reference signals into multiple groups based on their time domain resource occupancy, with each group assigned a dedicated measurement gap configuration. This segmentation allows the terminal device to measure different reference signal groups using different measurement gaps, ensuring complete measurement coverage while maintaining manageable device complexity through structured organization.
2Measurement precision
If a terminal device uses multiple measurement gap configurations to measure all reference signals, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent creates a correspondence between multiple measurement gap configurations and multiple reference signal groups, where each measurement gap configuration can be universally applied to measure its corresponding reference signal group. This multi-functionality approach allows the system to handle diverse reference signals with different time domain resources using a unified framework, improving measurement precision without proportionally increasing complexity.

AI summary
Embodiments of this application provide a communication method and apparatus. The method includes: receiving a correspondence from a network device, where the correspondence is a correspondence between N measurement gap configurations and N reference signal groups, one or more reference signals included in the reference signal group occupy a same time domain resource, the N reference signal groups are in a one-to-one correspondence with the N measurement gap configurations, and N is an integer greater than 1; and for one first measurement gap configuration in the N measurement gap configurations, measuring, based on the first measurement gap configuration, one or more reference signals included in a first reference signal group corresponding to the first measurement gap configuration. The correspondence between the N measurement gap configurations and the N reference signal groups is received from the network device, so that all reference signals that need to be measured by a terminal device can be measured. This avoids a technical problem that a part of reference signals cannot be measured because the terminal device can measure a reference signal only in one measurement gap in frequency domain.
