UE Measurement Gap Request Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing measurement gaps to balance power savings and accurate multiple subscriber identity module (MSIM) measurements, particularly in 5G deployments where uniform coverage is not guaranteed.
Innovation Solution
The proposed solution involves a user equipment (UE) assisted measurement gap request and release mechanism, where the UE transmits messages to the network to configure, reconfigure, or release measurement gaps, allowing for power savings and MSIM tune-away operations.

Engineering Contradiction Analysis
1Productivity
If the network configures measurement gaps autonomously without UE assistance, then the network maintains full control over measurement scheduling, but the measurement gap configuration speed is slow and power saving opportunities are lost
Solution Approach 1:
The UE autonomously determines and requests measurement gap configurations based on its own measurement needs and power saving requirements, rather than waiting for network configuration. The UE self-evaluates whether measurement gaps are needed and initiates the configuration request process, enabling faster adaptation to changing conditions.
Solution Approach 2:
The UE prepares and transmits measurement gap configuration requests in advance based on predicted measurement needs, allowing the network to pre-configure measurement gaps before they are actually required. This preliminary action reduces latency in measurement gap establishment.
2Measurement precision
If measurement gaps are configured frequently to ensure accurate MSIM measurements, then measurement accuracy improves, but power consumption increases due to more frequent communication suspensions
Solution Approach 1:
The UE requests measurement gaps with a degree of excessiveness, configuring more measurement gaps than strictly necessary for accurate measurements. This ensures measurement accuracy is maintained while the actual usage of these gaps remains selective, allowing the UE to power down during non-critical periods.
Solution Approach 2:
Measurement gaps are configured periodically rather than continuously, allowing the UE to suspend communication and perform measurements at regular intervals. This periodic approach maintains measurement accuracy while significantly reducing power consumption compared to continuous measurement operations.
3Loss of energy
If the UE autonomously requests measurement gap configurations, then power saving and measurement efficiency improve, but the network control over measurement scheduling is reduced
Solution Approach 1:
The UE provides feedback to the network regarding its measurement needs and power saving status, allowing the network to adjust measurement gap configurations based on actual UE conditions. This feedback mechanism maintains network control while enabling adaptive power saving measures.
Solution Approach 2:
The measurement gap configuration system becomes dynamic, with the UE able to request, modify, and release measurement gaps based on changing conditions. The network responds to these dynamic requests, creating a flexible system that adapts to both measurement needs and power saving requirements in real-time.
4Reliability
If measurement gap release is delayed to ensure continuous measurement capability, then measurement coverage is maintained, but network throughput decreases due to prolonged communication suspensions
Solution Approach 1:
The UE transmits measurement gap release requests in advance before the measurement gaps are actually needed, allowing the network to pre-release measurement gap configurations. This preliminary action reduces the duration of communication suspensions while ensuring measurements are completed before release takes effect.
Solution Approach 2:
The measurement gap release timing becomes dynamic rather than fixed, with the network adjusting release schedules based on current measurement needs and network conditions. This dynamic approach optimizes the balance between maintaining measurement coverage and maximizing network throughput in real-time.

AI summary
A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.
