Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems lack a solution for simultaneously sending and receiving multiple control channels, data channels, and reference signals due to constraints in analog beam scheduling.
Innovation Solution
Implementing a channel configuration method that includes receiving and configuring second channel characteristic assumptions for control channel resources, using both a first and second type of search space, to enable simultaneous scheduling of control, data, and reference signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If analog beam scheduling constraints are applied to control channels and data channels, then device complexity is reduced, but the ability to simultaneously send and receive multiple channels is limited
Solution Approach 1:
The patent segments the search space into two distinct types: first type search space for control channels and second type search space for data channels. This segmentation allows independent configuration and scheduling of control and data channels, enabling simultaneous transmission while maintaining manageable complexity through specialized handling of each channel type.
Solution Approach 2:
The patent introduces a new dimension for resource scheduling by defining separate search space types with different channel characteristic assumptions. This dimensional separation in the resource allocation space allows the system to schedule multiple channels simultaneously without increasing analog beam scheduling complexity, as each search space type operates with its own configured parameters.
2Productivity
If multiple control channels, data channels and reference signals are scheduled simultaneously, then transmission performance is improved, but channel configuration complexity increases
Solution Approach 1:
By dividing the search space into first type (for control channels) and second type (for data channels), the patent enables simultaneous scheduling of multiple channels while managing configuration complexity through type-specific rules. Each search space type has dedicated configuration parameters, allowing parallel channel scheduling without requiring complex cross-channel coordination.
Solution Approach 2:
The patent applies different channel characteristic assumptions locally to different search space types. The first type search space uses assumptions optimized for control channels, while the second type uses assumptions optimized for data channels. This localized optimization allows each channel type to be configured independently with appropriate parameters, improving overall transmission performance while keeping individual configuration tasks manageable.
3Adaptability or versatility
If separate search space types are configured for control and data channels, then simultaneous scheduling is enabled, but signaling overhead increases
Solution Approach 1:
The patent creates a universal search space configuration framework where both first type and second type search spaces share common configuration structures and parameters. This multi-functionality allows the same configuration mechanism to serve both control and data channels, enabling simultaneous scheduling while reducing redundant signaling. The unified configuration approach minimizes overhead by avoiding duplicate parameter definitions.

AI summary
Provided are channel configuration and power control methods and devices, a user equipment, a base station and storage mediums. The channel configuration method is configured to receive a second channel characteristic assumption of a control channel resource set configured by a second communication node; where the control channel resource set is formed by at least one of a first type of search space and a second type of search space; the second channel characteristic assumption is used for configuration of control channel resources in the second type of search space; and the control channel resource transmitted by the second communication node are received according to the second channel characteristic assumption.
