Solution Overview

Problem

In 5G mobile communication systems, existing beam management methods prevent network devices from simultaneously using multiple carriers sharing a radio frequency channel, limiting user capacity and reducing communication efficiency.

Innovation Solution

A measurement reporting method that configures a pilot association relationship among carriers sharing a radio frequency channel, allowing the network device to use multiple carriers simultaneously by associating pilots with the same spatial domain transmit filter, thereby enabling carrier aggregation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing beam management methods are used when multiple carriers share one radio frequency channel, then device complexity is reduced, but productivity deteriorates because the network device cannot simultaneously use multiple carriers to communicate with the terminal device

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidbeam management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges beam management across multiple carriers by associating pilots of different carriers with the same spatial domain transmit filter. This allows the network device to use a unified beam management approach for multiple carriers sharing a radio frequency channel, enabling simultaneous communication on multiple carriers while maintaining manageable complexity through the association relationship.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent makes the spatial domain transmit filter universal across multiple carriers. A single spatial domain transmit filter can be applied to pilots of multiple carriers simultaneously, allowing the same beamforming configuration to serve multiple carriers. This multi-functionality enables simultaneous use of multiple carriers without proportionally increasing beam management complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Quantity of substance

If multiple carriers share one radio frequency channel without pilot association relationship, then device complexity is low, but quantity of substance deteriorates because user capacity is limited

Engineering Contradiction:
Improveuser capacityVSAvoidpilot management complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines pilot management across multiple carriers by establishing an association relationship where pilots of different carriers correspond to the same spatial domain transmit filter. This merging approach allows the system to manage pilots collectively rather than independently for each carrier, increasing user capacity while controlling pilot management complexity through the association mechanism.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

This application provides a measurement reporting method and an apparatus. The method includes: receiving pilot measurement configuration information of a plurality of carriers, where the pilot measurement configuration information indicates a pilot association relationship of the plurality of carriers, and the pilot association relationship indicates that pilots of the plurality of carriers correspond to a same spatial domain transmit filter; performing measurement based on the pilot measurement configuration information, to obtain measurement report results of the plurality of carriers; and sending the measurement report results. The pilot association relationship of the plurality of carriers is configured for a terminal device, so that the terminal device may report, for the plurality of carriers, measurement results of the pilots corresponding to one or more same spatial domain transmit filters.
