Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing beam management schemes in 5G and beyond are inflexible and prone to performance degradation due to inappropriate beam selection by user equipment (UE), leading to issues like beam collision and increased signaling overhead.

Innovation Solution

A UE-oriented beam management scheme where the terminal directly determines the beam for communication, with a pre-certification process by the base station to ensure appropriate beam selection and network permission based on UE capability and communication environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the base station controls beam selection in conventional beam management schemes, then beam management is simple to implement, but the system flexibility is reduced and performance degradation occurs due to inappropriate beam selection by UE

Engineering Contradiction:

Improvebeam management flexibilityVSAvoidbeam management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent inverts the conventional beam management approach by enabling the UE to autonomously determine and select beams instead of the base station controlling beam selection. This inversion allows the UE to adapt to rapid channel changes and select appropriate beams based on its own measurements, thereby improving flexibility and performance while reducing inappropriate beam selection issues

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If the UE autonomously determines beams without certification, then beam management flexibility increases, but beam collision and performance degradation occur

Engineering Contradiction:

Improvebeam management flexibilityVSAvoidbeam selection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a pre-certification process where the base station provides certification information to the UE before autonomous beam determination. This preliminary action includes providing SSB index information and TCI state indications that guide the UE's beam selection, ensuring reliable beam choices while maintaining flexibility. The certification information serves as advance guidance to prevent beam collision and performance degradation

Inventive Principle:

Principle #10Preliminary action

3Reliability

If conventional beam management is used, then signaling overhead is reduced, but performance degradation occurs due to inappropriate beam selection

Engineering Contradiction:

Improvebeam selection accuracyVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts and utilizes already-transmitted certification information (SSB index information and TCI state indications) that the base station sends for other purposes. By reusing this existing information for beam determination, the system achieves accurate beam selection without generating additional signaling overhead, thus improving reliability while avoiding increased information loss

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An embodiment of the disclosure relates to a method and apparatus for transmitting multicast data to a terminal in a 5G network. The method comprises: identifying to perform a terminal based beam management based on at least one of a communication environment or a capability of the terminal; transmitting, to a base station, a first message for requesting an allowance of the terminal based beam management; and receiving, from the base station, a second message including information indicating whether the terminal based beam management is allowed.
