Radio Resource Allocation for Power Saving in Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in radio communication systems is the increased power consumption due to delayed release of radio resources during data transfers, which can lead to inefficient use of system resources and higher energy consumption, especially in scenarios like dual-carrier operations where both frequencies are continuously monitored.
Innovation Solution
Implementing a method to dynamically reduce the use of radio resources during periods of delayed data flow by reducing the number of transmission timeslots monitored, and resuming full allocation when data transfer resumes, using power saving logic within mobile stations and base stations to manage radio resource reduction and resumption efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio resources are continuously allocated during data transfers, then service quality is maintained, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the radio resource allocation flexible and adaptive rather than static. The system dynamically adjusts the allocation of transmission timeslots based on real-time data flow conditions, switching between full allocation during active data transfer and reduced allocation during gaps, thereby optimizing both service quality and power consumption.
Solution Approach 2:
The patent changes the parameter of radio resource allocation by introducing a reduction factor that determines the number of transmission timeslots to be monitored. This parameter is adjusted based on data flow activity - set to maintain full service quality during active transfer and reduced during gaps, directly addressing the contradiction between service quality and power consumption.
2Use of energy by moving object
If radio resources are reduced during data gaps, then power consumption decreases, but data transfer resumption may be delayed
Solution Approach 1:
The patent applies preliminary action by maintaining the radio resource allocation in a reduced state during data gaps, preparing the system for efficient resumption. The power saving logic continuously monitors for data flow resumption, and upon detection, immediately restores full resource allocation, thus minimizing the time loss while still achieving power savings during the gap period.
Solution Approach 2:
The system uses feedback mechanisms where the power saving logic continuously monitors data flow conditions and adjusts radio resource allocation accordingly. When data transfer resumes, the monitoring detects this change and triggers the restoration of full resource allocation, ensuring quick resumption while maintaining power efficiency during idle periods.
3Productivity
If full radio resource allocation is maintained, then data transfer speed is maximized, but energy efficiency deteriorates
Solution Approach 1:
The patent applies periodic action by alternating between two states of radio resource allocation: full allocation during active data transfer periods and reduced allocation during data gaps. This periodic switching optimizes energy efficiency during idle periods while ensuring full productivity when data transfer is needed, directly addressing the contradiction between data transfer speed and energy efficiency.
Solution Approach 2:
The patent applies partial action by allocating only the necessary portion of radio resources during data gaps rather than maintaining full allocation. The reduction factor determines the partial allocation level, which is sufficient to maintain basic connectivity while significantly reducing energy consumption, and full allocation is restored when complete data transfer capability is needed.

AI summary
An approach for reducing power consumption during data transfer is provided. A period of delayed release of one or more radio resources associated with a data flow is detected. In response to the detection, radio resource reduction information is generated for a data transfer during the period, wherein the radio resource reduction information specifies a reduced allocation of one or more radio resources. Control information is generated for transmission to a mobile station, wherein the control information specifies the radio resource reduction information.
