Dynamic Receive Diversity Switching for Mobile UE Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased demand for mobile broadband access in wireless communication networks leads to higher interference and power consumption due to the use of receive diversity systems, which consume more power and are inefficient during periods of low data activity.
Innovation Solution
Implementing dynamic receive diversity switching in user equipment (UE) that enables or disables receive diversity based on data activity measurements, switching to a lower power state when data activity is low to conserve battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receive diversity is continuously enabled to improve signal reception quality, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic receive diversity switching that adapts the diversity configuration based on current data activity conditions. The system transitions between receive diversity enabled and disabled states dynamically, rather than maintaining a fixed configuration. This resolves the contradiction by enabling high reliability only when data activity is detected, while conserving power during idle periods.
Solution Approach 2:
The system changes the operational parameters of the receive diversity function based on measured data activity. When data activity is detected, the receive diversity is enabled; when no data activity is present, it is disabled. This parameter change approach allows the system to optimize between reliability and power consumption by adjusting the diversity state according to actual communication needs.
2Productivity
If receive diversity is enabled to improve data transmission performance, then communication speed is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamic switching of receive diversity based on data activity measurements. The system monitors for data activity conditions and enables receive diversity only when such conditions are detected, otherwise maintaining a disabled state. This dynamic approach improves data transmission performance when needed while minimizing power consumption during idle periods.
3Reliability
If receive diversity is continuously active to maintain communication reliability, then signal quality is improved, but battery life decreases
Solution Approach 1:
The system employs periodic monitoring of data activity conditions to determine when to enable or disable receive diversity. By periodically checking for data activity and adjusting the diversity state accordingly, the system maintains reliability during active communication while conserving battery life during idle periods, thus extending overall battery duration.
Solution Approach 2:
The patent implements dynamic state transitions for receive diversity based on detected data activity. The system switches between enabled and disabled states dynamically, ensuring communication reliability is maintained only when data transmission is occurring, thereby preserving battery life during non-active periods.

AI summary
Dynamically control of receive diversity switching in a user equipment (UE) is disclosed. By dynamically controlling the switching between enabling and disabling the receive diversity, power consumption in UEs, such as smart phones and other mobile devices may be reduced. Control is based, at least in part, on measurements for data activity performed by the UE. When the UE finds measurements that would suggest data activity, the UE will switch to enable a receive diversity state when conditions are available for the switch. Similarly, when the UE finds measurements that would suggest data inactivity, the UE will switch to disable the receive diversity state when conditions are available for the switch.
