5G UE Antenna Switching for Lower Power Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR communication systems, user equipment (UE) with multiple receiving antennas consumes unnecessary power when all antennas are turned on, even if not all are needed for certain services, leading to inefficient power usage.
Innovation Solution
The UE adjusts the number of receiving and transmitting antennas based on channel state information and service requirements, turning off antennas when not needed to reduce power consumption while maintaining performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all receiving antennas are turned on in UE, then spatial multiplexing gain and signal reception capability are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic antenna adjustment where the UE can change the number of active receiving antennas based on service requirements and channel conditions. The antenna configuration is not fixed but adapts dynamically - for example, using 4 antennas for high-data-rate services and reducing to 2 antennas for low-data-rate services, thereby optimizing the balance between reception capability and power consumption.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by adjusting the number of active receiving antennas according to different service types and channel states. This parameter adjustment allows the system to operate at different performance levels - maintaining high reception capability when needed while reducing power consumption when lower performance suffices.
2Productivity
If multiple receiving antennas are used in UE, then spatial multiplexing capacity and downlink rate increase, but device complexity increases
Solution Approach 1:
The patent employs dynamic antenna configuration that adapts to service requirements. Rather than maintaining a fixed complex 4-antenna setup for all services, the system dynamically adjusts the active antenna count - using 4 antennas for high-productivity services requiring spatial multiplexing, and reducing to 2 antennas for simpler services, thereby managing device complexity while maintaining productivity when needed.
3Reliability
If all antennas are always turned on, then signal transmission performance is maintained, but power efficiency deteriorates
Solution Approach 1:
The patent implements parameter changes in the antenna system by adjusting the number of active receiving antennas based on service requirements and channel conditions. This allows the system to maintain high signal transmission performance when needed (using 4 antennas) while improving power efficiency when lower performance is acceptable (using 2 antennas), thereby resolving the contradiction between reliability and energy loss.
Solution Approach 2:
The patent employs periodic assessment of service requirements and channel conditions to determine the appropriate antenna configuration. The system periodically evaluates whether to use 4 or 2 antennas based on current needs, creating a rhythm of adjustment that maintains performance when necessary while conserving energy during periods when full capability is not required.
