Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning measurement gaps are continuously activated to improve positioning accuracy, then positioning precision is improved, but resource utilization deteriorates due to unnecessary gap usage during non-positioning periods
Solution Approach 1:
The patent implements dynamic management of positioning measurement gaps by allowing wireless devices to trigger activation or deactivation based on positioning requirements. The network receives triggering conditions from the wireless device and dynamically activates measurement gaps only when positioning is needed, rather than maintaining continuous activation. This dynamic approach resolves the contradiction by adapting the measurement gap state to actual positioning needs.
Solution Approach 2:
The patent changes the operational parameter of measurement gaps from a static continuous activation state to a dynamic state that transitions between active and inactive based on triggering conditions. The network configures the wireless device with parameters for triggering activation/deactivation, and the device monitors these conditions to change the measurement gap state accordingly, optimizing both positioning accuracy and resource utilization.
2Loss of energy
If positioning measurement gaps are dynamically activated and deactivated based on triggering conditions, then resource utilization is improved, but positioning accuracy may deteriorate if activation is delayed
Solution Approach 1:
The patent implements preliminary action by having the network pre-configure the wireless device with triggering conditions and parameters for measurement gap activation before positioning is actually needed. The wireless device continuously monitors these pre-configured conditions and can immediately activate measurement gaps when conditions are met, eliminating activation delays while maintaining resource efficiency during non-positioning periods.
3Loss of energy
If the network manually manages measurement gap activation to optimize resource usage, then resource utilization is improved, but system complexity increases due to additional control signaling
Solution Approach 1:
The patent implements self-service by enabling the wireless device to autonomously trigger measurement gap activation or deactivation based on pre-configured positioning requirements and triggering conditions. The network provides the configuration and receives the triggering indication, but the actual activation decision is made by the wireless device itself, reducing system complexity while maintaining resource optimization.

AI summary
A wireless device receives one or more radio resource configuration (RRC) messages comprising one or more configuration parameters comprising a first configuration parameter and first measurement configuration parameters indicating one or more positioning measurement gaps. In response to the first configuration parameter being enabled, the wireless device determines to trigger a positioning measurement gap activation or deactivation request. Based on the one or more RRC messages comprising the first configuration parameter, the wireless device determines to trigger the positioning measurement gap activation or deactivation request using an uplink medium access control (MAC) control element (CE). The wireless device transmits the uplink MAC CE for activating or deactivating a positioning measurement gap of the one or more positioning measurement gaps.
