Time-Domain Resource Allocation for Overlapping SSB and PDSCH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face challenges in efficiently allocating time domain resources for high-frequency communication systems, particularly in scenarios where synchronization signal physical broadcast channel blocks (SSBs) overlap with physical downlink shared channel (PDSCH) transmissions, limiting the flexibility and efficiency of resource allocation for minimum system information (RMSI) transmission.
Innovation Solution
A method and apparatus for determining time domain resource allocation patterns based on combinations of subcarrier spacings (SCS) and downlink control information (DCI) signaling, allowing for flexible and efficient allocation of resources for both synchronization signals and RMSI/PDSCH transmissions, even in cases of overlapping symbols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple time domain resource allocation patterns are configured for different SCS combinations, then resource allocation adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic time domain resource allocation by enabling the network to flexibly switch between different resource allocation patterns (Type A and Type B) based on the specific SCS combination being used. This allows the system to adapt to varying service requirements and spectral efficiency demands without requiring static configuration for all possible scenarios, thereby improving adaptability while controlling complexity through on-demand pattern selection
Solution Approach 2:
The patent changes the allocation pattern type parameter based on the SCS combination configuration. When the SCS combination changes, the system dynamically adjusts which allocation pattern (Type A or Type B) is applied, allowing optimal resource allocation for each specific SCS scenario. This parameter-based adaptation resolves the contradiction by linking allocation behavior directly to the operational configuration rather than requiring separate configurations for each scenario
2Productivity
If dynamic time domain resource allocation is implemented, then spectral efficiency is improved, but uplink and downlink resource allocation conflicts increase
Solution Approach 1:
The patent segments the resource allocation mechanism into two distinct types (Type A and Type B), each optimized for specific SCS combinations. Type A is applied to certain SCS combinations while Type B is applied to others, preventing conflicts by ensuring that each resource allocation scenario uses the appropriate segmented approach. This segmentation allows dynamic resource allocation to improve spectral efficiency while avoiding the harmful effects of allocation conflicts through structured differentiation
Solution Approach 2:
The patent introduces an intermediary mechanism (the determination module) that mediates between the dynamic resource allocation requirements and the potential conflicts. This intermediary intelligently selects which allocation pattern to apply based on the SCS combination, acting as a mediator that resolves potential conflicts before they occur by pre-determining the appropriate allocation strategy for each scenario
3Manufacturing precision
If resource allocation patterns are determined based on SCS combination, then resource allocation accuracy is improved, but detection and measurement difficulty increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring and storing multiple time domain resource allocation patterns corresponding to different SCS combinations before actual resource allocation occurs. When a specific SCS combination is detected, the system can directly retrieve and apply the pre-determined appropriate pattern, improving allocation accuracy while reducing the detection difficulty since the determination logic is already established in advance rather than requiring complex real-time analysis

AI summary
Provided are time domain resource determination and detection methods and apparatuses, a storage medium and an electronic device. The method includes determining a time domain resource allocation pattern set. The time domain resource allocation pattern set includes at least one of a time domain resource allocation pattern set corresponding to a combination of a first subcarrier spacing (SCS) and a second SCS, where the first SCS is a SCS of a first channel signal, and the second SCS is a SCS of a second channel signal; a time domain resource allocation pattern set indicated by downlink control information (DCI) signaling; or a time domain resource allocation pattern set corresponding to a slot type. A time domain resource allocation pattern in the time domain resource allocation pattern set is used to indicate symbols occupied by the second channel signal.
