Uplink Transmission Power Prioritization With Overlap Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing transmission power adjustments due to overlapping uplink transmissions, leading to power reductions or dropping without timely awareness by the network, which impacts UE performance and coordination.
Innovation Solution
User equipment (UE) provides indications to the network about power reduction or dropping due to overlapping uplink transmissions, using uplink control information (UCI) or medium access control (MAC) elements, specifying affected channels or cells, to facilitate timely network adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs uplink transmissions without network awareness of overlapping conditions, then the UE can maintain transmission continuity, but the network cannot perform coordinated power management leading to power waste and communication quality degradation
Solution Approach 1:
The patent implements a feedback mechanism where the UE sends an indication message to the network element when overlapping uplink transmissions are detected. This feedback loop enables the network to become aware of the UE's power limitation situation, allowing coordinated power management adjustments. The network can then respond by adjusting scheduling decisions or power allocation to avoid conflicts and maintain communication quality.
2Productivity
If the UE adjusts transmission power due to overlapping transmissions without network coordination, then the UE can manage its own power, but the network cannot optimize resource allocation leading to inefficiency
Solution Approach 1:
The indication message sent by the UE to the network element provides real-time feedback about overlapping transmission conditions. This enables the network to optimize resource allocation by adjusting scheduling decisions, avoiding conflicting transmissions, and efficiently managing power resources across multiple UEs.
Solution Approach 2:
The UE autonomously detects overlapping uplink transmissions and sends indications to the network without requiring continuous network intervention. This self-service approach allows the UE to manage its own power limitations while still enabling network-wide optimization through the information provided.
3Reliability
If the network is not informed of uplink transmission adjustments, then the system maintains simplicity, but power management coordination is lost impacting overall system performance
Solution Approach 1:
The patent introduces a feedback mechanism where the UE sends indication messages to the network element about overlapping transmission conditions. This relatively simple feedback loop enables coordinated power management without requiring complex continuous monitoring or control mechanisms, maintaining system simplicity while improving reliability.

AI summary
Systems, methods, apparatuses, and computer program products for enhanced operation for transmission power operation. A method may include receiving, from a network element, a configuration to transmit an indication of an uplink transmission adjustment to the network element. The method may also include determining an existence of overlapping of uplink transmissions to the network element. The method may further include transmitting, in response to the determination of the existence of overlapping of uplink transmissions, the indication to the network element. In addition, the method may include performing, in response to the determination of the existence of overlapping of uplink transmissions, at least one of the uplink transmission adjustment of the uplink transmission to the network element or an uplink scheduling adjustment.
