AI Technical Summary

Technical Problem

Existing wireless communication systems have accuracy and efficiency problems when sending and receiving signals, especially when processing downlink signals.

Method used

More accurate and efficient transmission and reception of signals is achieved by receiving the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) in the user equipment (UE), and repeatedly receiving the PDSCH portion exceeding the UE's supported bandwidth in the time domain.

Benefits of technology

This method can perform signal transmission and reception in wireless communication systems more accurately and efficiently, improving signal reception performance, especially in the case of limited bandwidth.

Abstract

A method by which a UE receives a signal in a wireless communication system according to an embodiment includes: receiving downlink control information (DCI) via a physical downlink control channel (PDCCH); and receiving a Physical Downlink Shared Channel (PDSCH) repeated in a time domain based on the DCI, where the UE may alternately receive different portions of the PDSCH in respective repetitions of the PDSCH based on the PDSCH scheduled by the DCI exceeding a PDSCH bandwidth supported by the UE.
