Uplink Signal Prioritization for Non-Serving Cell SSB Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face limitations in leveraging full-duplex capabilities due to scheduling constraints that prevent dynamic prioritization of uplink signals and non-serving cell synchronization signals, leading to reduced communication flexibility and efficiency.
Innovation Solution
Implementing prioritization rules that allow a user equipment (UE) to dynamically prioritize either uplink signals or non-serving cell synchronization signals (SSBs) based on overlapping resource sets, enabling full-duplex operation by transmitting or monitoring one while deferring the other to non-overlapping resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scheduling constraints are enforced to prevent resource conflicts, then system reliability is improved, but communication flexibility and productivity deteriorate
Solution Approach 1:
The patent implements dynamic prioritization rules that allow the UE to flexibly switch between different transmission modes based on real-time conditions. The UE can dynamically prioritize uplink signals or SSB transmissions depending on which has higher priority at any given moment, rather than being constrained by fixed scheduling rules. This dynamic approach resolves the contradiction by maintaining reliability through structured prioritization while achieving flexibility through adaptive decision-making.
Solution Approach 2:
The patent changes the parameter of resource allocation from static to dynamic by introducing prioritization rules that adjust transmission behavior based on signal priority. The system modifies transmission parameters (which signal to transmit or monitor) based on changing conditions, allowing the UE to adapt its communication pattern while maintaining system reliability through defined prioritization logic.
2Productivity
If full-duplex capabilities are implemented, then spectral efficiency and productivity are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The patent enables the UE to autonomously determine transmission priorities using self-service mechanisms. The UE independently evaluates which signal (uplink or SSB) has higher priority based on predefined rules and automatically makes transmission decisions without complex network coordination. This reduces device complexity by shifting the decision-making burden from the network to the UE, while still enabling full-duplex operations that improve spectral efficiency.
3Productivity
If dynamic prioritization is enabled, then communication efficiency and productivity are improved, but loss of time for decision-making increases
Solution Approach 1:
The patent applies preliminary action by pre-defining prioritization rules and criteria before transmission decisions are needed. The UE is provided with advance guidance on how to prioritize different signal types under various conditions. This eliminates the need for complex real-time analysis during transmission decisions, reducing decision-making time while maintaining communication efficiency through pre-planned prioritization strategies.

AI summary
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multiplexing and prioritization techniques for uplink signaling and non-serving cell synchronization signals. In some aspects, a user equipment (UE) and a network entity may support a prioritization rule according to which the UE and the network entity may enable uplink multiplexing with a set of non-serving cell synchronization signal blocks (SSBs). For example, an uplink signal and a set of non-serving cell SSBs may be scheduled for the UE and may at least partially overlap in time and the UE may prioritize one of the uplink signal or the set of non-serving cell SSBs in accordance with the prioritization rule. The prioritization rule may be associated with a scheduling offset of the uplink signal or may be associated with whether the set of non-serving cell SSBs are indicated for measurement at the UE.
