PUCCH Configuration for Flexible Duplex Uplink Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the flexible duplex mode, the available uplink resources in both downlink and uplink symbols of a TDD frame structure have different bandwidths and interference characteristics, which affects the performance of Physical Uplink Control Channel (PUCCH) transmissions if they are configured uniformly.
Innovation Solution
The method involves receiving or sending configuration information from a network side device to a terminal, where multiple sets of configuration information are configured for a single PUCCH resource, each set corresponding to a time domain unit with specific requirements, allowing for tailored parameter settings such as time-frequency location, code rate, and power based on the characteristics of different uplink resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single PUCCH configuration is used for all uplink resources, then device complexity is reduced, but PUCCH transmission performance deteriorates due to mismatched parameters for different resource characteristics
Solution Approach 1:
The patent segments the PUCCH configuration into multiple sets, where each set is tailored to specific uplink resource characteristics (e.g., different bandwidths, interference levels, time-frequency locations). The network device configures multiple PUCCH resource sets with different parameters, and the terminal selects the appropriate set based on the current uplink resource conditions, thereby resolving the contradiction between configuration simplicity and transmission performance.
Solution Approach 2:
The patent introduces dynamic selection mechanisms where the terminal can switch between different PUCCH configuration sets based on real-time uplink resource characteristics. This dynamic adaptation allows the system to optimize PUCCH transmission parameters according to varying channel conditions, interference levels, and resource allocations, improving reliability without requiring permanent complex configuration structures.
2Reliability
If multiple sets of configuration information are configured for different time domain units, then PUCCH transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by configuring different PUCCH parameter sets for different time domain units based on their specific characteristics. Each time domain unit (e.g., slot, subframe) can have customized PUCCH configurations tailored to its local conditions such as interference levels, bandwidth availability, and traffic patterns. This localized optimization improves transmission performance while managing complexity through targeted rather than universal configuration.
Solution Approach 2:
The patent utilizes parameter changes by allowing the network to dynamically adjust PUCCH configuration parameters (such as frequency location, bandwidth, cyclic shift, orthogonal cover code) based on uplink resource conditions. The terminal receives configuration information that includes multiple parameter sets and selects/apples the appropriate parameters for each time domain unit, enabling performance optimization through parameter adaptation without requiring complete reconfiguration of the system.
