Dual-Receiver State Switching for Power-Efficient Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminal devices with multiple receivers face challenges in balancing receiving performance and power consumption, particularly when using different receiving states that affect energy efficiency and mobility.
Innovation Solution
A method for wireless communication that allows a terminal device to determine a target receiving state based on the power consumption of its receivers, turning off or putting a high-power first receiver into a deep sleep state and activating a low-power second receiver as needed, and using a low-power LP-WUS receiver for wake-up signals to optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device uses the first receiver in a normal transceiving state, then receiving performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic receiving state switching between first and second receiving states based on service requirements. The terminal device can flexibly transition between high-performance/high-power and low-performance/low-power states, making the system adaptable to varying operational conditions rather than being static
Solution Approach 2:
The patent changes the operational parameters of the receiver by introducing different receiving states with distinct power consumption and performance characteristics. By adjusting the receiver's operational mode (first state vs. second state), the system optimizes the trade-off between receiving performance and power consumption based on actual needs
2Use of energy by moving object
If the terminal device switches receiving states frequently, then power consumption is reduced, but state determination complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the terminal device reports service requirement information to the network device, and the network device provides downlink signal quality information back to the terminal. This closed-loop feedback enables intelligent state switching decisions based on actual channel conditions and service needs, reducing unnecessary switching
Solution Approach 2:
The patent performs preliminary assessment of service requirements and downlink signal quality before switching receiving states. By evaluating conditions in advance and using predetermined switching criteria, the system avoids frequent or unnecessary state transitions, simplifying the determination process

AI summary
Provided are a method for wireless communication, a terminal device, and a network device. The method comprises: a terminal device determines a target receiving state, wherein the terminal device comprises a first receiver and a second receiver, the power consumption of the second receiver is less than the power consumption of the first receiver, the target receiving state is a first receiving state or a second receiving state, the first receiving state corresponds to the first receiver being turned off or in a deep sleep state, and the second receiving state corresponds to the first receiver being turned on and in a normal transceiving state. According to the technical solution of embodiments of the present application, signal receiving can be carried out by using different target receiving states in different scenarios, and the receiving performance and power consumption of a terminal device are both taken into account.
