Solution Overview

Problem

Current power control methods in mobile communication networks are ineffective in reducing power consumption, especially when the proportion of power consumption from transmit channels is small, as they rely on turning off channels intermittently, which does not significantly lower overall network device power usage.

Innovation Solution

A power control method and apparatus that determines if there is uplink data in a scheduling period for a receive channel, and if not, sets the channel to an off state, including the option to turn off receive ends and low noise amplifiers, and performs aggregation scheduling to increase idle scheduling periods, thereby reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If transmit channels are turned off at intervals to reduce power consumption, then power consumption is reduced when transmit channels account for a large proportion of total power consumption, but power consumption cannot be effectively reduced when transmit channels account for a small proportion of total power consumption

Engineering Contradiction:
Improvepower consumption of network deviceVSAvoideffectiveness of power reduction
Core Design Contradiction:
Use of energy by stationary objectVSProductivity

Solution Approach 1:

The patent segments the receive channel into multiple components (receive end, low noise amplifier) that can be independently controlled. By turning off specific components of the receive channel when not needed, the system achieves finer-grained power management rather than treating the entire channel as a single unit, thereby effectively reducing power consumption even when transmit channels consume a small proportion of total power.

Inventive Principle:
Principle #1Segmentation

2Use of energy by stationary object

If receive channel components are turned off to reduce power consumption, then power consumption is reduced, but the ability to receive uplink data is compromised

Engineering Contradiction:
Improvepower consumption of receive channelVSAvoiduplink data reception capability
Core Design Contradiction:
Use of energy by stationary objectVSReliability

Solution Approach 1:

The patent implements dynamic control of receive channel components based on real-time uplink data requirements. The system continuously monitors whether uplink data needs to be received and dynamically adjusts the state of receive channel components accordingly. This dynamic approach ensures that components are turned off only when not needed, maintaining reliability while reducing power consumption during idle periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms to monitor uplink data reception requirements and adjust the power state of receive channel components accordingly. By continuously checking whether uplink data is present and responding to this feedback, the system ensures that receive channel components are activated only when necessary, thereby maintaining reliable data reception while minimizing power consumption during idle periods.

Inventive Principle:
Principle #23Feedback

3Use of energy by stationary object

If aggregation scheduling is performed to increase idle scheduling periods, then more scheduling periods become idle and power consumption decreases, but scheduling complexity increases

Engineering Contradiction:
Improvepower consumption of network deviceVSAvoidscheduling complexity
Core Design Contradiction:
Use of energy by stationary objectVSDevice complexity

Solution Approach 1:

The patent applies aggregation scheduling to combine multiple uplink data transmissions into fewer scheduling periods. By merging data from multiple periods into consolidated scheduling events, the system creates more idle scheduling periods where receive channel components can be turned off. This merging approach increases power savings opportunities while managing scheduling complexity through systematic consolidation rather than individual period management.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A power control method and apparatus, and a device. The method includes: determining, by a network device, whether there is to-be-received uplink data in a first scheduling period on a first receive channel; and in response to determining that there is no to-be-received uplink data in the first scheduling period on the first receive channel, controlling, by the network device, a state of the first receive channel in the first scheduling period to be an off state. This reduces power consumption of the network device.
