PDSCH RATE-MATCHING IN NTN - A simplified explanation of the abstract

This abstract first appeared for US patent application 17455373 titled 'PDSCH RATE-MATCHING IN NTN

Simplified Explanation

The patent application describes a system for PDSCH rate-matching in NTN systems. Here are the key points:

• The system is designed for a UE (User Equipment) in a wireless communication network.
• The UE receives an indication of a subset of SSB (Synchronization Signal Block) beams that have PDCCH (Physical Downlink Control Channel) resources reserved for scheduling SIBs (System Information Blocks).
• The UE also receives a PDSCH (Physical Downlink Shared Channel) associated with resources that overlap with the PDCCH resources of the indicated subset of SSB beams.
• The UE performs rate-matching around the PDCCH resources of the indicated subset of SSB beams to properly receive the PDSCH.

Potential applications of this technology:

• Wireless communication networks using NTN (New Radio Technology).
• UE devices in 5G or future generations of wireless networks.
• Systems requiring efficient and reliable transmission of system information blocks.

Problems solved by this technology:

• Efficient scheduling of SIBs in wireless communication networks.
• Proper reception of PDSCH in the presence of overlapping resources.
• Optimization of rate-matching techniques for improved data transmission.

Benefits of this technology:

• Improved reliability and efficiency of system information block scheduling.
• Enhanced performance of UE devices in wireless networks.
• Better utilization of available resources for data transmission.

Original Abstract Submitted

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PDSCH rate-matching in NTN systems. A UE may receive an indication of a subset of one or more SSB beams included in a set of SSB beams having one or more PDCCH resources reserved for potentially scheduling one or more SIBs associated with the set of SSB beams. The UE may further receive a PDSCH associated with resources that overlap with at least a portion of the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams, and rate-match around the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams for receiving the PDSCH.
