Unequal MCS Indication for Flexible RU-Based Wireless Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices struggle to flexibly indicate unequal modulation and coding scheme (MCS) capabilities, particularly in wireless communication systems, which affects resource allocation and efficiency.
Innovation Solution
A method and apparatus for indicating unequal MCS capabilities by specifying conditions such as bandwidth, resource unit size, or multiple resource unit size, allowing devices to communicate their supported MCS configurations accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a communication device uses a fixed MCS indication method, then the device complexity is reduced, but the adaptability to different bandwidth, RU size, and MRU size conditions deteriorates
Solution Approach 1:
The patent implements dynamic MCS indication by allowing the first communication device to flexibly indicate unequal MCS capabilities under different specified conditions (bandwidth, RU size, MRU size). The indication information adapts its content based on the actual communication scenario, transforming a static capability indication into a dynamic one that responds to varying system conditions.
Solution Approach 2:
The patent changes the parameters of the indication information based on different specified conditions. The indication information includes MCS parameters that vary according to bandwidth, RU size, and MRU size conditions, allowing the communication device to indicate appropriate MCS capabilities for each specific condition rather than using a fixed indication method.
2Adaptability or versatility
If the indication information includes all possible MCS configurations, then the adaptability is improved, but the information transmission overhead increases
Solution Approach 1:
The patent extracts only the necessary MCS capability information relevant to the current specified condition and includes it in the indication information. Rather than transmitting all possible MCS configurations, the system extracts and transmits only the subset of MCS capabilities that are applicable under the current bandwidth, RU size, or MRU size condition, reducing information overhead while maintaining adaptability.
Solution Approach 2:
The patent implements partial indication by including only the necessary portion of MCS configuration information needed for the current communication scenario. The indication information contains MCS parameters that are sufficient for the specific condition at hand, avoiding the excessive transmission of all possible MCS configurations that would be unnecessary for the current situation.

AI summary
A modulation and coding scheme (MCS) indication method includes a first device determining an unequal MCS configuration. The first device sends indication information to a second device. The indication information indicates the unequal MCS configuration supported by the first device under a specified condition, and the specified condition includes at least one of the following: a bandwidth corresponding to the unequal MCS configuration, a size of a resource unit (RU) corresponding to the unequal MCS configuration, or a size of a multiple resource unit (MRU) corresponding to the unequal MCS configuration.
