Beam-Based Priority for Overlapping Semi-Static Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing overlapping communication occasions and prioritizing beam-based configurations in semi-statically configured communications, leading to potential delays and resource inefficiencies.
Innovation Solution
The method involves a user equipment (UE) and base station that receive and transmit communications based on beam-based priority, where overlapping communication occasions are identified and prioritized using quasi-co-location information and transmission configuration information states, allowing for efficient communication by selecting the appropriate communication occasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple semi-statically configured communications are transmitted with overlapping communication occasions, then communication reliability is improved, but resource efficiency deteriorates due to conflicts and delays
Solution Approach 1:
The patent changes the parameter of communication occasion priority by associating different priorities with different communication occasions. The network device configures multiple communication occasions with different priorities, and the terminal device selects which occasion to use based on the priority associated with the uplink grant, thereby resolving conflicts without wasting resources
Solution Approach 2:
The patent segments the communication occasions into different priority levels. By dividing communication occasions into high-priority and low-priority categories, the system can handle overlapping communications systematically, selecting high-priority occasions when conflicts occur, thus maintaining reliability while optimizing resource usage
2Device complexity
If communication occasions are prioritized without beam-based differentiation, then device complexity is reduced, but communication performance deteriorates due to inability to handle beam-specific conflicts
Solution Approach 1:
The patent applies local quality by associating different priorities with different beams or spatial directions. Each communication occasion is linked to a specific beam, and priority is determined based on the beam association. This allows the system to handle beam-specific conflicts locally without increasing overall device complexity significantly
Solution Approach 2:
The patent implements preliminary action by pre-configuring priority associations between communication occasions and beams before actual communication occurs. The network device provides RRC configuration that establishes these priority relationships in advance, so when conflicts occur, the terminal can immediately apply the pre-determined priority rules without complex real-time decisions

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration for a first set of semi-statically configured communications. The UE may receive a second configuration for a second set of semi-statically configured communications, wherein a first communication occasion of the first configuration at least partially overlaps with a second communication occasion of the second configuration. The UE may transmit or receive a communication, via the first communication occasion or the second communication occasion, based at least in part on a beam-based priority of the first configuration or the second configuration. Numerous other aspects are described.
