Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE specifications define a fixed transient period for network node configurations, which does not account for varying capabilities of wireless devices, particularly in new radio technologies supporting multiple numerologies and frequency bands, leading to suboptimal performance.
Innovation Solution
Wireless devices determine and signal transient time parameters associated with signal transmissions, allowing network nodes to adapt transmitter and receiver configurations based on these parameters, optimizing demodulation performance.

1Reliability
If a fixed transient period is defined in network specifications, then network node configurations are simplified and standardized, but device-specific optimization is prevented leading to suboptimal performance
Solution Approach 1:
The patent introduces dynamic transient time parameters that can be signaled from the network to the wireless device, allowing the transient time to vary based on device capabilities and network conditions rather than being fixed. This enables the system to adapt the transient time duration to match specific device characteristics while maintaining network-wide coordination.
Solution Approach 2:
The patent changes the transient time parameter from a fixed specification value to a configurable parameter that can be signaled and adjusted. The network can indicate different transient time values to different devices or under different conditions, allowing optimization for various device capabilities while maintaining standardized configuration procedures.
2Adaptability or versatility
If transient time requirements are relaxed for new radio technologies, then device capabilities are improved and flexibility increased, but network demodulation performance may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the network signals the supported transient time to the wireless device, and the device uses this information to configure its transient time parameter. This closed-loop approach ensures that the device operates with optimized transient time while the network maintains awareness of the actual transient time being used, thereby preserving demodulation performance.
Solution Approach 2:
The patent performs preliminary configuration by signaling the supported transient time before actual data transmission begins. This allows the wireless device to pre-configure its transient time parameter according to network indications, ensuring that both transmitter and receiver are synchronized on the transient time value before communication starts, thus avoiding performance degradation.
3Adaptability or versatility
If multiple transient time parameters are supported for different numerologies, then system flexibility and optimization are improved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent applies different transient time parameters locally to different numerologies rather than using a single global parameter. Each numerology can have its own transient time configuration, allowing optimization for specific frequency ranges and subcarrier spacings while keeping the configuration management localized and manageable through standardized signaling procedures.
