Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face interference issues due to shared resources among multiple users, leading to degraded performance, especially in heterogeneous networks with varying power levels and timing discrepancies, which complicates server selection and resource management.
Innovation Solution
Implementing separate resource partition schedules for uplink control and data signals, allowing for different periodicities and subframe assignments to coordinate both data and control transmissions, thereby reducing interference and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate resource partition schedules are implemented for uplink control and data signals, then interference is minimized and network performance is enhanced, but device complexity increases due to the need to manage and coordinate multiple schedules
Solution Approach 1:
The patent applies segmentation by dividing the uplink transmission resources into separate partitions for control signals and data signals. The base station generates and manages distinct resource partition schedules for each signal type, allowing independent optimization of resource allocation. This segmentation reduces interference between control and data transmissions while enabling tailored scheduling strategies for each partition type.
2Reliability
If different periodicities are used for control and data transmissions, then transmission coordination is improved and interference is reduced, but timing synchronization becomes more complex
Solution Approach 1:
The patent implements dynamics by allowing different periodicities for control and data signal transmissions. The base station can independently configure the scheduling periodicity for each signal type, enabling adaptive timing that optimizes interference avoidance and resource utilization. This dynamic approach permits the system to adjust timing parameters based on specific transmission requirements without enforcing uniform periodicity across all signal types.
3Productivity
If separate resource schedules are generated and broadcast to UEs, then resource utilization is optimized, but system overhead increases due to additional control information transmission
Solution Approach 1:
The patent applies universality by designing the resource partition schedules to serve multiple functions. The same scheduling mechanism provides both control signal allocation and data signal allocation, with the base station generating comprehensive schedules that cover all uplink transmission needs. This multi-functional approach allows efficient resource utilization across different signal types while managing overhead through unified scheduling frameworks.

AI summary
Transmission management is provided with separate resource partitioning management for control and data transmissions. An evolved node B (eNB) generates separate resource partition schedules for the transmission stream, in which a first schedule (703) is used for data transmissions while a second schedule (704) is used for control signal transmissions. The two separate schemes may have different periodicities or different subframe type assignments that benefit either data or control transmissions or that allow for coordination of both data and control. The eNBs may broadcast the different schedules in regular system information messages, in which the UEs served by these eNBs will configure data and control signal transmissions according to the appropriate resource partition schedules.
