UCI Code Rate Compensation for SBFD and Uplink Time Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In TDD communication systems, the reuse of uplink time unit transmission parameters in subband full duplex (SBFD) time units leads to reduced UCI transmission reliability and affected communication efficiency due to channel environment and interference differences.
Innovation Solution
A communication method that involves determining code rate compensation parameters based on N sets of first indexes for SBFD time units and P sets of second indexes for uplink time units, allowing for adaptive code rate compensation to improve UCI transmission reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the transmission parameter of the uplink time unit is reused in the SBFD time unit, then the device complexity is reduced, but the reliability of UCI transmission is reduced
Solution Approach 1:
The patent applies local quality by differentiating parameter configuration between different time unit types. Specifically, it configures separate code rate compensation parameters for SBFD time units and uplink time units, allowing each type to have optimized parameters tailored to its specific channel characteristics and interference environment, thereby improving UCI transmission reliability without requiring complete parameter redundancy
Solution Approach 2:
The patent implements parameter changes by introducing different code rate compensation parameters (first parameter for SBFD time units, second parameter for uplink time units) that adapt to the specific channel environments and interference characteristics of each time unit type, enabling optimized transmission performance for each scenario
2Ease of operation
If the transmission parameter of the uplink time unit is reused in the SBFD time unit, then the ease of operation is improved, but the communication efficiency is affected
