Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping is employed to enhance uplink channel reliability, then communication robustness is improved, but system complexity increases
Solution Approach 1:
The patent segments the uplink channel transmission into multiple resource sub-blocks, each associated with different spatial relations and information elements. This segmentation allows beam sweeping to be performed across multiple divided resources rather than as a single complex operation, thereby enhancing reliability while managing system complexity through modular resource organization.
Solution Approach 2:
The patent dynamically selects and activates different information elements (first information element, second information element) based on the number of resource sub-blocks configured. When resource sub-blocks > 1, both information elements are activated for beam sweeping; when resource sub-blocks = 1, only one is activated. This dynamic adaptation enables the system to adjust beam sweeping intensity according to channel conditions, improving reliability while controlling complexity.
2Reliability
If multiple information elements are activated for beam sweeping, then uplink channel robustness is enhanced, but signaling overhead increases
Solution Approach 1:
The system dynamically activates either one or two information elements based on the configured number of resource sub-blocks. When resource sub-blocks = 1, only the first information element is activated; when resource sub-blocks > 1, both first and second information elements are activated. This dynamic activation strategy ensures sufficient beam sweeping capability for robustness while minimizing signaling overhead by activating only the necessary number of information elements for each transmission scenario.
Solution Approach 2:
The patent changes the activation state of information elements as a parameter based on the resource configuration. The number of activated information elements varies (1 or 2) depending on whether resource sub-blocks equals 1 or greater than 1. This parameter change approach allows the system to adapt the level of beam sweeping and associated signaling overhead to match the actual channel requirements, balancing robustness enhancement with overhead control.

AI summary
A method and a device in a node for wireless communications are disclosed in the present disclosure. A first node receives a first information block set, receives a first signaling and a first signal, and transmits a first bit block in a first radio resource block. The first information block set is used to activate a first information element and a second information element out of N information elements; when the first radio resource block only comprises one resource sub-block, only one of the first information element and the second information element is used to determine a spatial relation of the first radio resource block; when the first radio resource block comprises K resource sub-blocks, K being a positive integer greater than 1, the first information element is used to determine a spatial relation of at least one resource sub-block in the first radio resource block.
