Signal Carrier Configuration Bit Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing signal carrier configurations, particularly in activating and deactivating carriers, which leads to increased bit requirements for communicating desired configurations, especially when multiple carriers are active.
Innovation Solution
The system employs a method to reduce the number of bits needed for signal carrier configuration by selecting the appropriate carrier for transmitting orders, utilizing two-bit, three-bit, or four-bit orders based on the number of active carriers, and using specific orders to indicate active or inactive states of carriers, thereby optimizing bit usage.

Engineering Contradiction Analysis
1Loss of information
If traditional bit allocation methods are used for signal carrier configuration, then all carrier states can be represented, but the number of bits required increases unnecessarily
Solution Approach 1:
The patent segments the carrier configuration information into two parts: a primary carrier indicator and a secondary carrier configuration. The primary carrier (e.g., PCell) is identified separately from supplemental carriers (e.g., SCell), allowing the system to use fewer bits for the primary carrier while allocating bits efficiently for supplemental carriers based on the actual number of active carriers.
Solution Approach 2:
The patent implements dynamic bit allocation where the number of bits required for carrier configuration changes based on the number of active carriers. When fewer carriers are active, fewer bits are needed; when more carriers are active, the system dynamically adjusts the bit allocation to match the actual configuration requirements, avoiding static over-provisioning of bits.
2Productivity
If fixed bit allocation is used for carrier configuration, then implementation is simple, but bit efficiency decreases when multiple carriers are active
Solution Approach 1:
The patent changes the parameter of bit allocation from a fixed value to a dynamic value that adapts to the number of active carriers. The system uses different bit allocation schemes depending on whether one, two, three, or four carriers are active, optimizing the balance between communication efficiency and bit consumption for each specific scenario.
3Measurement precision
If comprehensive carrier state information is transmitted, then configuration accuracy is high, but transmission overhead increases
Solution Approach 1:
The patent performs preliminary identification of the primary carrier state before configuring supplemental carriers. By first establishing which carrier is the primary carrier (PCell) and which are supplemental carriers (SCell), the system can then efficiently encode the configuration information, ensuring accurate configuration while minimizing redundant information transmission.

AI summary
Systems and methods for effectuating a signal carrier configuration are disclosed. In one embodiment, the method comprises receiving an order, determining a signal carrier on which the order was received, determining a signal carrier configuration based at least in part on the order and the determined signal carrier, and changing the state of one or more signal carriers to effectuate the signal carrier configuration.
