1Area of stationary object
If beam-based transmissions and receptions are used to ensure coverage in high-frequency channels, then coverage range is improved, but the system requires complex beam reporting mechanisms to accurately indicate beam qualities
Solution Approach 1:
The patent changes the parameter representation method by encoding beam quality information using differential values and compact indexing schemes. Instead of reporting absolute beam quality values for all beams, the system reports differential changes from a reference beam, significantly reducing the number of bits required while maintaining accurate beam quality indication.
Solution Approach 2:
The patent extracts only the essential beam quality information needed for beam management by identifying and reporting only the differential quality metrics relative to a reference beam. This extraction approach eliminates redundant information and focuses on the critical parameters that enable effective beam selection and quality assessment.
2Measurement precision
If existing beam reporting methods are used, then beam identifiers can be reported, but accurate indication of beam qualities is lacking, hindering optimal beam-directional communications
Solution Approach 1:
The patent implements a feedback mechanism where the terminal measures reference signals, determines beam qualities, and reports differential quality information back to the network device. This feedback loop enables the network device to accurately assess beam qualities and make informed decisions about beam selection and communication parameter adjustment, thereby improving beam-directional communication efficiency.
Solution Approach 2:
The patent performs preliminary beam quality measurements and differential calculations at the terminal side before reporting to the network device. By pre-processing the beam quality information and computing differential values relative to a reference beam, the system reduces the complexity of network device processing while maintaining high measurement precision.
3Reliability
If comprehensive beam quality information is reported, then optimal beam selection is enabled, but reporting overhead and processing complexity increase
Solution Approach 1:
The patent transforms the beam quality information representation by using differential encoding relative to a reference beam. Instead of reporting absolute quality values for multiple beams, the system reports differential values that capture the relative quality differences, significantly reducing the information bits required while preserving the ability to determine optimal beam selection.
Solution Approach 2:
The patent reports only the necessary differential beam quality information rather than complete absolute quality data for all beams. By reporting partial information (differential values relative to reference) that is sufficient for beam selection decisions, the system achieves optimal beam selection while minimizing reporting overhead.
