Wireless Frame Reception With Adaptive Capability Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face high power consumption due to unnecessary activation of all receive chains during frame exchanges, even when not required, leading to inefficient power management.
Innovation Solution
Implementing a capability adaptation power save mode that allows devices to operate at a lower capability level during awake states, reducing power consumption by limiting operations to a first capability mode that is lower than the device's full capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication device operates in awake state with full capability, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by enabling the communication device to dynamically switch between different capability modes (first capability mode with lower power consumption and second capability mode with higher performance) based on communication requirements. The device can transition between these modes during operation, allowing it to adapt its resource allocation and processing power to match actual needs, thereby resolving the contradiction between maintaining high communication performance and reducing power consumption.
Solution Approach 2:
The patent utilizes parameter changes by modifying operational parameters such as receive chain activation, processing capability levels, and resource allocation based on the selected capability mode. When in the first capability mode, the device adjusts parameters to consume less power (e.g., limiting receive chains), while in the second capability mode, it increases parameters to enhance communication performance, thus dynamically balancing power consumption and performance.
2Reliability
If a communication device activates all receive chains during frame exchange, then reception capability is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by activating only the necessary number of receive chains based on the current capability mode and communication requirements, rather than always activating all available receive chains. In the first capability mode, the device activates fewer receive chains to reduce power consumption, while in the second capability mode, it activates more receive chains to improve reception capability, thus avoiding unnecessary energy expenditure while maintaining adequate reception performance.
3Use of energy by moving object
If a communication device operates in lower capability mode, then power consumption is reduced, but communication performance decreases
Solution Approach 1:
The patent resolves this contradiction through dynamic capability mode switching, allowing the device to transition between the first capability mode (lower power consumption) and the second capability mode (higher communication performance) based on real-time communication needs. This dynamic adaptation ensures that the device operates at the appropriate performance level for each situation, avoiding both excessive power consumption and insufficient performance.
Solution Approach 2:
The patent applies universality by designing the communication device to support multiple capability modes within a single system architecture. The device can function effectively in both the first capability mode and the second capability mode, making it universally adaptable to different operational requirements and environments, thus achieving both power efficiency and high performance when needed.

AI summary
Provided are wireless communication methods and communication devices. A method comprises: a first device receives a first frame sent by a second device, wherein transmission and/or reception of the first frame meet the requirements of a first capability mode of the first device, the first device is capable of using the first capability mode to monitor and/or receive in a wake-up state, and the first capability corresponding to the first capability mode is lower than the capability of the first device. When the first device performs an operation on the basis of the capability of the first device, the first device is in a full-power state. In the present application, the first capability is a lower capability, such that performing an operation on the basis of the first capability mode can reduce power consumption during an operation execution process, thus achieving the effect of reducing energy consumption of the first device.
