UE Transmission Gap Configuration for Flexible Wireless Link Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack flexibility in scheduling transmission and reception gaps for user equipment (UE) measurements, failing to account for varying measurement capabilities of different UEs, which affects power consumption and resource utilization during handover procedures.
Innovation Solution
A communication system where the UE and wireless access network propose candidate transmission gap configurations, allowing the UE to select the most suitable configuration based on its capabilities, while the network retains control over gap configuration, enabling efficient handover initiation and power-saving connected states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the UTRAN configures transmission gaps using the static UMTS mechanism, then the gap scheduling is straightforward and simple to implement, but the system lacks flexibility and cannot accommodate differing measurement capabilities of different UEs
Solution Approach 1:
The patent applies dynamics by transitioning from a static gap configuration mechanism to a dynamic one where the UE can autonomously select gap configurations from multiple candidates provided by the network. This allows the system to adapt to different UE measurement capabilities while maintaining network control, resolving the contradiction between implementation simplicity and flexibility.
2Measurement precision
If the UE performs handover-related measurements continuously, then measurement accuracy is improved, but power consumption increases significantly
Solution Approach 1:
The patent implements periodic action by scheduling measurements to occur only during configured transmission gaps rather than continuously. The UE performs measurements periodically during these gaps while remaining in connected mode, which maintains measurement capability while significantly reducing power consumption compared to continuous measurement approaches.
3Use of energy by moving object
If the UE enters power-saving connected mode with DRX/DTX, then power consumption is reduced, but the UE cannot perform network-controlled handover measurements
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously select appropriate gap configurations from candidates provided by the network based on its own measurement capabilities and power saving requirements. This allows the UE to self-manage its measurement activities during connected mode DRX/DTX, maintaining both power saving benefits and the ability to perform measurements needed for network-controlled handover.

AI summary
A method for measuring at least one neighboring cell by a user equipment, UE, in a communication system, the method comprising: receiving, from a network, a message representative of an s-Measure including a serving cell quality threshold and gap configuration information used for setting up and releasing measurement gaps; setting up measurement gap configuration indicated by the gap configuration information; performing measurement of the at least one neighboring cell based on the s-Measure and the measurement gap configuration; and transmitting, to the network, a measurement report based on the measurement, if a condition for measurement report is fulfilled.
