Uplink CoMP Enhancement Mode Selection for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly at cell edges, signal strength is low due to greater distance from the base station, and interference from neighboring cells is high, affecting the quality of service, which existing CoMP schemes partially address but require dynamic adjustment of uplink CoMP enhancement modes based on UE type and battery power to optimize power usage and throughput.
Innovation Solution
A method to dynamically select between battery-saving and throughput-enhancement modes for uplink CoMP in UE devices, specifically determining the UE type and remaining battery power to choose the appropriate mode, allowing eNodeBs to provide uplink CoMP service effectively, enhancing throughput for HPUEs and conserving power for non-HPUEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CoMP schemes are implemented to improve service at cell edges, then quality of service is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent implements dynamic selection between battery-saving mode and throughput-enhancement mode based on real-time conditions. The system adjusts CoMP enhancement modes dynamically according to UE type (HPUE or non-HPUE) and battery power levels, rather than using a fixed configuration. This dynamic adaptation allows the system to optimize between quality of service and power consumption/complexity based on current operational requirements.
2Productivity
If throughput-enhancement mode is used for CoMP, then uplink throughput is improved, but power consumption increases
Solution Approach 1:
The patent changes operational parameters (CoMP enhancement mode) based on UE type and battery power conditions. For HPUE devices with sufficient battery power, the system selects throughput-enhancement mode to maximize uplink throughput. For non-HPUE devices or devices with low battery power, the system selects battery-saving mode to reduce power consumption. This parameter adaptation resolves the contradiction by matching the throughput enhancement level to the device's power capabilities and requirements.
3Use of energy by moving object
If battery-saving mode is used for CoMP, then power consumption is reduced, but uplink throughput decreases
Solution Approach 1:
The system dynamically adjusts the CoMP enhancement mode parameter based on device characteristics and power state. When a non-HPUE device reports low battery power, the system switches to battery-saving mode, accepting reduced throughput in exchange for lower power consumption. This parameter change is appropriate because non-HPUE devices have limited power transmission capabilities anyway, so the priority shifts to extending battery life rather than maximizing throughput.
4Productivity
If CoMP enhancement modes are dynamically adjusted based on UE type and battery power, then power efficiency and throughput are optimized, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports its battery power level to the base station, and the base station determines the appropriate CoMP enhancement mode based on this feedback along with UE type information. This feedback loop enables automated, context-aware mode selection without requiring complex user input or manual configuration. The system complexity is justified by the significant gains in power efficiency and throughput optimization that result from this adaptive approach.

AI summary
Methods and systems are disclosed that can help to select an enhancement mode for uplink coordinated multipoint (CoMP). An exemplary method involves: determining a measure of remaining battery power of a first user equipment (UE), wherein the first UE is capable of uplink coordinated multipoint (CoMP) communication; determining a particular UE type of the first UE, wherein the particular UE type is one of a plurality of possible UE types; based at least in part on (a) the particular UE type of the first UE, and (b) the measure of remaining battery power of the first UE, selecting either a battery-saving mode or a throughput-enhancement mode as an uplink CoMP enhancement mode for the first UE; and providing uplink CoMP service to the first UE according to the selected uplink CoMP enhancement mode.
