Data transmission method and reception method for wireless communication system and device using same

A terminal of a wireless communication system, the terminal comprising:

• a communication module;
• and
• a processor configured to control the communication module,
• wherein the processor is configured to:
• receive a radio resource control (RRC) signal from a base station of the wireless communication system through the communication module,
• determine a first time-frequency resource corresponding to at least one resource-set indicated by the RRC signal,
• receive a physical control channel from the base station through the communication module, wherein the physical control channel schedules physical data channel in a plurality of slots,
• determine a second time-frequency resource in which the physical data channel reception of the terminal is scheduled by the physical control channel, wherein the first time-frequency resource overlaps the second time-frequency resource, wherein the overlapping time-frequency resource includes a plurality of sub-resource-sets,
• obtain a rate-matching indicator from the physical control channel, and
• receive a physical data channel according to the rate-matching indicator,
• wherein the resource-set is a set of time-frequency resources.
