Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face challenges with multiple trigger events in RFFE slave devices, which require significant space and high power consumption due to the use of multiple counters, impacting battery life and efficiency.
Innovation Solution
Implementing a single-counter system that consolidates the tracking of multiple trigger events, using a counter, comparator, and register configuration to reduce circuit size and power consumption, allowing a single counter to manage multiple trigger events for both single and multiple triggered elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple counters are used to track multiple trigger events in RFFE slave devices, then trigger tracking accuracy is improved, but circuit size increases and power consumption increases
Solution Approach 1:
The patent combines multiple trigger tracking functions into a single counter resource. The master device sends multiple trigger events with different trigger values to the slave device, which uses one counter to track all triggers by comparing incoming trigger values against the counter value, eliminating the need for separate counters for each trigger event.
Solution Approach 2:
The single counter in the slave device is designed to handle multiple trigger tracking functions universally. By comparing the counter value with multiple different trigger values received from the master, the same counter resource can accurately track multiple different trigger events, making the counter multi-functional.

3Area of stationary object
If a single counter is used to track multiple trigger events, then circuit size is reduced and power consumption is reduced, but trigger handling complexity increases
Solution Approach 1:
The patent introduces trigger values as an intermediary mechanism between the master and slave devices. These trigger values serve as reference points that the slave's single counter compares against incoming trigger events, simplifying the slave's hardware while maintaining accurate multi-trigger tracking capability through the intermediary comparison process.
4Use of energy by stationary object
If a single counter is used to track multiple trigger events, then power consumption is reduced, but trigger synchronization difficulty increases
Solution Approach 1:
The master device performs preliminary actions by pre-calculating and sending trigger values to the slave device before the actual trigger events occur. This preliminary provision of reference values enables the slave's single counter to synchronize and accurately track multiple trigger events without requiring complex real-time synchronization mechanisms.

AI summary
Single-counter, multi-trigger systems and methods in communication systems consolidate tracking of multiple trigger events into a single counter in place of plural counters. The single counter may track multiple trigger events for a single triggered element. Likewise, the single counter may track trigger events for a plurality of triggered elements. By consolidating tracking of trigger events with reference to a single counter, the size of the circuit may be reduced and power savings may be achieved.
