Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming technology is deployed to meet high-speed data transmission demand, then network capacity and data transmission speed are improved, but network energy consumption increases
Solution Approach 1:
The patent implements discontinuous transmission (DTX) for beam groups, where transmission is periodically activated and deactivated based on data availability and QoS requirements. This periodic action allows the network to maintain beamforming capability when needed while reducing energy consumption during periods of low or no data transmission, directly resolving the contradiction between maintaining network capacity and reducing energy usage.
Solution Approach 2:
The patent introduces dynamic beam group management where beam groups can be activated or deactivated based on real-time network conditions, data traffic patterns, and QoS requirements. This dynamic adjustment allows the system to adapt beamforming resource allocation to actual demand, improving energy efficiency while maintaining network capacity when required.
2Reliability
If continuous beam transmission is maintained to ensure service quality, then reliability of data transmission is improved, but energy consumption increases
Solution Approach 1:
The patent changes the transmission state parameter from continuous to discontinuous by introducing DTX operation. Transmission parameters such as active duration, inactive duration, and activation conditions are adjusted based on QoS requirements and data traffic patterns, allowing the system to maintain reliability when needed while reducing energy consumption during appropriate periods.
Solution Approach 2:
The patent performs preliminary assessment of data availability, QoS requirements, and channel conditions before activating beam transmission. This preliminary action ensures that transmission is only initiated when necessary to maintain service quality, avoiding unnecessary energy consumption while preserving reliability when data needs to be transmitted.
3Productivity
If multiple beams are activated to serve multiple users, then network capacity and user service coverage are improved, but interference between beams increases
Solution Approach 1:
The patent segments the beam management system into multiple beam groups, where each group can be independently controlled for activation and deactivation. This segmentation allows the system to activate only the necessary beam groups for current users, reducing the total number of active beams and thereby minimizing interference while maintaining adequate service coverage.
Solution Approach 2:
The patent applies different transmission states (active or inactive) to different beam groups based on local conditions such as user presence, data traffic, and QoS requirements. This local quality approach ensures that beams are activated only in specific locations where needed, reducing overall interference while maintaining service coverage for active users.

AI summary
A method of a UE may comprise: receiving beam DTX group configuration information from a base station through a first beam or a second beam; monitoring reception of first beam DTX group control information indicating beam DTX activation for at least one beam of the first beam or the second beam based on the beam DTX group configuration information; determining whether beam DTX activation for the first beam is indicated based on reception of the first beam DTX group control information; and performing discontinuous reception of DL wireless signals from the base station through the first beam, based on the beam DTX activation being indicated for the first beam.
