Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing uplink quality of service (QoS) for shared channel transmission, particularly in efficiently allocating power resources between different logical channels with varying priority levels, leading to potential power budget issues and compromised user experience.
Innovation Solution
A method and apparatus for wireless communication that dynamically adjust transmit configurations based on priority levels and expected payloads, allowing for separate power allocation to different logical channels during ON and OFF durations of an uplink transmission interval, ensuring sufficient power for high-priority communications by reserving energy and adjusting buffer status reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is allocated dynamically based on priority levels and expected payloads, then power management efficiency and high-priority communication reliability are improved, but device complexity and control mechanism complexity increase
Solution Approach 1:
The patent segments the power allocation process by separating high-priority and low-priority logical channels into distinct power budgets. The high-priority logical channels are allocated a dedicated power portion that is reserved and protected, while low-priority channels share the remaining power. This segmentation ensures reliable power supply for critical communications without requiring complex real-time power adjustment mechanisms for all channels uniformly.
Solution Approach 2:
The patent applies local quality by assigning different power allocation characteristics to different logical channels based on their priority levels. High-priority logical channels receive a guaranteed power portion with higher reliability, while low-priority channels receive variable power allocation. This differentiated approach allows the system to maintain simple overall control while providing enhanced reliability where needed.
2Use of energy by moving object
If separate power allocation is implemented for different logical channels during ON and OFF durations, then power budget management and energy efficiency are improved, but transmission interval configuration complexity increases
Solution Approach 1:
The patent implements periodic action by establishing regular ON and OFF duration cycles for uplink transmissions. During ON durations, the UE transmits high-priority logical channel data using allocated power; during OFF durations, transmissions are suspended or reduced. This periodic structure simplifies power budget management by creating predictable power consumption patterns, reducing the complexity of continuous power allocation decisions.
Solution Approach 2:
The patent applies preliminary action by pre-configuring power portions and transmission intervals before actual data transmission occurs. The network signals the UE about expected payloads and power allocations in advance, allowing the UE to prepare buffer status reports and power management decisions beforehand. This reduces real-time computational complexity and enables more efficient power distribution.
3Reliability
If buffer status reports are adjusted to account for reserved power for high-priority communications, then power budget accuracy and transmission reliability are improved, but processing complexity and overhead increase
Solution Approach 1:
The patent applies preliminary action by having the UE calculate and report buffer status information in advance, considering the reserved power for high-priority logical channels before actual transmission occurs. The UE determines expected payloads and adjusts buffer status reports to reflect the impact of power reservations, allowing the network to make informed scheduling decisions without requiring complex real-time processing during transmission.
Solution Approach 2:
The patent implements feedback by using adjusted buffer status reports as a communication mechanism between UE and network. The buffer status reports include information about available power portions and expected data volumes, enabling the network to feedback with appropriate power allocation decisions. This feedback loop simplifies the overall system by distributing intelligence and reducing the need for complex centralized control.
4Reliability
If power is reserved for high-priority logical channels during OFF durations, then communication reliability is improved, but available power for low-priority channels decreases
Solution Approach 1:
The patent segments the total power budget into distinct portions: a reserved power portion for high-priority logical channels and a remaining power portion for low-priority channels. During OFF durations, the reserved power for high-priority channels is maintained to ensure rapid and reliable transmission when needed, while the remaining power is allocated to low-priority channels. This segmentation allows both reliability and power availability to be maintained simultaneously through clear power portion separation.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting power allocation parameters based on priority levels, expected payloads, and transmission timing. The system changes power portion sizes, transmission intervals, and power levels according to the specific needs of different logical channels. This flexible parameter adjustment enables the system to guarantee power for high-priority channels while optimizing available power for low-priority channels based on actual traffic conditions.
