COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446575 titled 'COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a method for mapping a Physical Downlink Shared Channel (PDSCH) in a wireless communication system.

• The PDSCH of a legacy UE (User Equipment) is mapped to physical resources per subframe.
• The PDSCH of an LR-UE (Low-Rate User Equipment) is mapped to a specific region of the physical resources, based on the Physical Resource Blocks (PRBs) included in the subframe.
• The PDSCH of the legacy UE can also be mapped to physical resources per PRB pair, which includes two physical resource blocks.
• The PDSCH of the LR-UE is mapped to the remaining physical resources, excluding the PRB pairs used by the PDSCH of the legacy UE.

Original Abstract Submitted

A PDSCH of a legacy UE is mapped to physical resources per subframe, whereas a PDSCH of an LR-UE is mapped, per physical resource block (PRB) included in the subframe, to a region of the physical resources to which the PDSCH of the legacy UE is mapped. The PDSCH of the legacy UE may be also mapped to the physical resources per PRB pair including two physical resource blocks, whereas the PDSCH of the LR-UE may be mapped to the remaining physical resources excluding the PRB pairs to which the PDSCH of the legacy UE is mapped.
