Abstract
The present specification provides a method for transmitting and receiving physical signals and/or channels in a wireless communication system and an apparatus therefor. Specifically, a method for a terminal to receive a wireless signal and/or a channel in a wireless communication system may comprise the steps of: receiving, from a base station, downlink control information (DCI) for scheduling for one or more wireless signals and/or channels; and cross-receiving the one or more wireless signals and/or channels on a sub-block basis from the base station on the basis of the DCI.

A method for receiving a signal by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, a single downlink control information (DCI) that schedules a plurality of physical downlink shared channel (PDSCH) transmission blocks;
- and
- receiving, based on the DCI and from the base station, the plurality of PDSCH transmission blocks,
- wherein each PDSCH transmission block is repeated within a time duration comprising ‘N’ subunits each having a fixed time length in a time domain, where ‘N’ is a value determined based on the DCI,
- wherein the UE receives the plurality of PDSCH transmission blocks by interleaving the subunits of the plurality of PDSCH transmission blocks in the time domain,
- wherein a repeated reception for each PDSCH transmission block is configured,
- wherein the interleaving and the repeated reception are performed based on one pattern from among a plurality of patterns configured for the interleaving, and
- wherein the plurality of patterns includes:
- a first pattern of interleaving in which none of the ‘N’ subunits of a same PDSCH transmission block is consecutive in the time domain;
- and
- a second pattern of interleaving in which at least a part of the ‘N’ subunits of the same PDSCH transmission block is consecutive in the time domain,
- wherein a first total number of the plurality of PDSCH transmission blocks is supported for the first pattern, a second total number of the plurality of PDSCH transmission blocks is supported for the second pattern, and the first total number is different from the second total number.
