Wireless Node SSB Index Resource Pool Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE and future cellular networks, face limitations in resource allocation flexibility, which can impact the efficiency of User Equipment (UE) in performing blind decoding for downlink control channels.
Innovation Solution
The method involves using multiple SSB indexes to determine time-domain resources, allowing for a pool of resources that can be flexibly allocated between two candidate pools, enhancing compatibility and scheduling flexibility by indicating which SSBs are actually transmitted or not, and associating these with specific Physical Cell Identifiers (PCI).

Engineering Contradiction Analysis
1Productivity
If SSB indexes are used to determine time-domain resources for CSS sets, then UE blind decoding efficiency is improved, but resource allocation flexibility is limited
Solution Approach 1:
The time-domain resources are segmented into multiple candidate pools (first candidate pool and second candidate pool), where each pool corresponds to different SSB index ranges. This segmentation allows the system to selectively activate appropriate resource pools based on actual SSB transmission patterns, thereby maintaining blind decoding efficiency while improving resource allocation flexibility.
Solution Approach 2:
The patent introduces dynamic resource pool selection mechanisms where the UE can switch between different candidate pools based on received signaling indicating which SSB indexes are actually transmitted. This dynamic adaptation enables the system to optimize resource usage in real-time, resolving the contradiction between fixed resource allocation and flexible adaptation.
2Stability of the object's composition
If fixed resource allocation schemes are used for compatibility, then system stability is maintained, but scheduling flexibility is reduced
Solution Approach 1:
The patent designs a universal resource allocation framework that can accommodate both traditional fixed allocation schemes and new flexible allocation patterns. By defining multiple candidate pools that can be selectively activated, the system maintains backward compatibility with existing UEs while enabling enhanced scheduling flexibility through dynamic pool selection based on actual SSB transmission patterns.
Solution Approach 2:
The system changes the parameter of resource pool selection dynamically based on SSB transmission indicators. Instead of using a fixed resource allocation parameter, the system selects from multiple candidate pools (first candidate pool, second candidate pool) depending on which SSB indexes are actually transmitted, thereby achieving both stability and flexibility through parameter variation.

AI summary
The present application provides a method and device in a node for wireless communications. A first node receives a first signaling and a second signaling, the first signaling indicates that Q SSBs are transmitted, and the Q SSBs respectively correspond to Q SSB indexes, the Q SSB indexes are respectively used to determine Q time-domain resources, Q being a positive integer greater than 1; determines a first time-domain resource based on at least a first integer, a candidate of the first time-domain resource constitutes a first time-domain resource pool; monitors a downlink control signaling in the first time-domain resource. The present application has good compatibility and improves the flexibility of resource allocation.
