Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in beam scanning and demodulation due to the lack of correspondence between paging-scheduling signaling messages and synchronization blocks, particularly when using time division multiplexing, leading to increased complexity and power consumption.
Innovation Solution
Establishing a correspondence between synchronization blocks and paging-scheduling signaling messages, allowing them to share the same beam and airspace characteristics, and using pre-defined or configured time intervals and multiplexing modes to reduce unnecessary beam scanning and enhance demodulation efficiency.

Engineering Contradiction Analysis
1Reliability
If the paging-scheduling signaling message and the synchronization block adopt the time division multiplexing mode, then the beam scanning can be performed to acquire downlink transmitted and/or received beam information, but the expense and complexity of demodulating the paging-scheduling signaling message are increased
Solution Approach 1:
The terminal performs beam scanning and acquires downlink transmitted and/or received beam information in advance before receiving the paging-scheduling signaling message. This preliminary action allows the terminal to prepare the appropriate receive beam beforehand, enabling more efficient demodulation of the subsequent paging message without increasing overall system complexity.
Solution Approach 2:
The synchronization block serves as an intermediary that carries beam information which mediates the subsequent reception of the paging-scheduling signaling message. By extracting beam information from the synchronization block first, the terminal uses this intermediate information to facilitate the demodulation process of the paging message, reducing demodulation complexity.
2Loss of time
If the paging-scheduling signaling message and the synchronization block adopt the frequency division multiplexing mode, then the expense of beam scanning may be reduced, but the PAPR becomes relatively large which brings influences to link budget demand
Solution Approach 1:
The patent applies partial frequency division multiplexing where the synchronization block and paging-scheduling signaling message are transmitted in different frequency resources only when necessary (when terminal bandwidth supports it and beam scanning has been performed). Otherwise, they use time division multiplexing. This partial application of FDM reduces beam scanning expense in suitable scenarios while avoiding excessive PAPR in scenarios where TDM is more appropriate.
3Loss of time
If the paging-scheduling signaling message and the synchronization block adopt the frequency division multiplexing mode, then the expense of beam scanning may be reduced, but the paging-scheduling signaling message and the synchronization block cannot be multiplexed when a bandwidth supported by the terminal is relatively small
Solution Approach 1:
The patent implements a dynamic multiplexing scheme where the terminal and network can adaptively switch between time division multiplexing and frequency division multiplexing based on terminal bandwidth capabilities and current operational conditions. This dynamic approach allows FDM to be used when terminal bandwidth is sufficient (reducing beam scanning expense) while automatically falling back to TDM when terminal bandwidth is limited, thereby maintaining broad bandwidth adaptability across different terminal types.
