AI Technical Summary

Technical Problem

In 3GPP Release 17, existing technologies struggle to effectively handle PDSCH rate matching and channel coding between different cells during inter-cell multiple TRP operations, resulting in low signal transmission efficiency.

Method used

By configuring different CORESET pool indices and TCI states between different cells, and combining RRC signaling and MAC control elements, the mapping between CORESET pools and serving cells is realized, ensuring the correspondence between CORESET pool indices and physical cell identifiers, and supporting flexible configuration of inter-cell scheduling and rate matching modes.

Benefits of technology

It improves the signal transmission efficiency of multi-TRP operations between cells, enhances the flexibility and accuracy of PDSCH rate matching, supports signal processing between different cells, and improves the performance of the communication system.
