Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing synchronization signals/physical broadcast channel (SS/PBCH) blocks, particularly in reducing power consumption and latency while supporting on-demand transmission.
Innovation Solution
The implementation of an on-demand SS/PBCH block system, where user equipment (UE) determines distinct parameters for periodic and on-demand SS/PBCH blocks, including cell IDs and frequency locations, to differentiate and manage these blocks effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic SS/PBCH blocks are transmitted continuously, then synchronization and broadcast information are reliably provided, but power consumption increases
Solution Approach 1:
The system dynamically switches between periodic and on-demand SS/PBCH block transmission modes based on network conditions and UE requirements. The base station can configure different periodicities or activate on-demand transmission when synchronization events are detected, making the transmission pattern adaptive rather than static.
Solution Approach 2:
The system changes the transmission parameter from continuous periodic to event-triggered on-demand based on detected synchronization needs. When a UE reports synchronization failure or when network conditions require it, the transmission mode parameter is changed to reduce unnecessary power consumption while maintaining reliability when needed.
2Use of energy by moving object
If on-demand SS/PBCH blocks are transmitted only when needed, then power consumption is reduced, but latency increases
Solution Approach 1:
The base station pre-configures multiple SS/PBCH block resources and parameters before they are needed. When a UE reports synchronization needs, the base station can quickly activate pre-prepared on-demand blocks, reducing the latency that would otherwise result from setting up transmission resources from scratch.
Solution Approach 2:
The system implements a feedback mechanism where UEs report synchronization status and needs to the base station. This feedback loop allows the network to detect when synchronization is needed and trigger on-demand transmission, balancing power savings with timely response to actual synchronization requirements.
3Ease of operation
If distinct parameters are used for periodic and on-demand SS/PBCH blocks, then block differentiation is improved, but device complexity increases
Solution Approach 1:
The system segments SS/PBCH block parameters into distinct sets for periodic and on-demand transmission. By maintaining separate parameter configurations (such as different cell IDs, frequency locations, or time resources), the system makes it easier to identify and process each block type independently, reducing the complexity of managing mixed transmission modes.

AI summary
Methods and apparatuses for an operation for an on-demand synchronization signals/physical broadcast channel (SS/PBCH) block is provided. A method of a user equipment (UE) in a wireless communication system includes determining a first set of parameters for a first set of SS/PBCH blocks and determining a second set of parameters for a second set of SS/PBCH blocks. The first set of parameters includes a first cell identity (ID) and a first frequency location. The second set of parameters includes a second cell ID and a second frequency location. The first set of SS/PBCH blocks is periodic. The second set of SS/PBCH blocks is on-demand and indicated to be transmitted by a base station (BS). The method further includes receiving a first SS/PBCH block from the first set of SS/PBCH blocks and receiving a second SS/PBCH block from the second set of SS/PBCH blocks.
