Dynamic Transient Period Indication for Signal Demodulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for demodulating communication signals in mobile data communication are not flexible enough to accommodate varying transient period capabilities of different devices, leading to increased bit error rates due to power variation or resource block hopping.
Innovation Solution
An information transmission method that involves acquiring scenario information of a first device and sending capability indication information to a second device, indicating the transient period capability supported by the first device. This allows the second device to demodulate signals based on the actual transient period of the first device, rather than relying on fixed durations specified in the protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-duration demodulation method is used, then protocol compliance is maintained, but flexibility is reduced and bit error rate increases
Solution Approach 1:
The patent implements dynamic transient period capability indication, where the first device reports its actual transient period capability to the second device, enabling the demodulation timing to adapt dynamically to different device characteristics rather than using a fixed protocol-specified duration. This resolves the contradiction by making the system flexible through device-specific parameter reporting while maintaining reliability through accurate capability-based demodulation.
Solution Approach 2:
The patent changes the demodulation parameter from a fixed protocol value to a dynamic value based on reported transient period capability. The second device adjusts its demodulation timing according to the actual capability information received from the first device, allowing the system to adapt to different hardware characteristics while ensuring reliable signal recovery.
2Measurement precision
If fixed transition period is used for signal switching, then protocol simplicity is maintained, but device-specific transient period variations cause demodulation errors
Solution Approach 1:
The patent applies preliminary action by having the first device report its transient period capability to the second device before signal transmission begins. This advance information exchange allows the second device to configure its demodulation parameters correctly from the start, improving measurement precision without adding complex real-time adjustment mechanisms during signal transmission.

AI summary
The present application relates to an information transmission method and apparatus, an electronic device, and a storage medium. Scenario information indicating a communication scenario corresponding to a first device is obtained, and capability indication information indicating a transition duration capability supported by the first device is sent to a second device according to the scenario information, so that when demodulating a signal sent by the first device, the second device demodulates or decides whether to demodulate the signal according to an actual transition duration of the first device, and the actual transition duration is usually a duration closely related to the first device itself, not a fixed duration stipulated by an agreement. Therefore, when demodulating the signal sent by the first device, the second device is enabled to flexibly perform demodulation according to the transition duration capabilities of different first devices, and the flexibility of signal demodulation is improved.
