Method and device for transmitting and receiving wireless sig-nals in wireless communication system

A device for wireless communication, the device comprising:

• a memory configured to store instructions;
• and
• a processor configured to perform operations by executing the instructions,
• wherein the operations of the processor comprise:
• receiving configuration information regarding a first signal;
• receiving a second signal including information regarding the first signal on at least one of time resources determined based on a plurality of periodicities configured in the UE;
• determining validity of the configuration information regarding the first signal based on the reception of the second signal;
• and
• performing an operation related to the first signal based on a determination that the configuration information regarding the first signal is valid,
• wherein the plurality of periodicities include a first periodicity and a second periodicity having a smaller length than the first periodicity,
• wherein the processor is configured to determine an interval between time resource groups related to the time resources based on the first periodicity and determine an interval between time resources within each time resource group based on the second periodicity, and
• wherein the processor is configured to determine the validity of the configuration information regarding the first signal based on a location of a time resource on which the second signal is received within a corresponding time resource group.

A method of transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting configuration information regarding a first signal to a user equipment (UE);
• and
• transmitting, to the UE, a second signal including information regarding the first signal on at least one of time resources determined based on a plurality of periodicities,
• wherein the BS indicates, to the UE, validity of the configuration information regarding the first signal based on transmitting the second signal,
• wherein the plurality of periodicities include a first periodicity and a second periodicity having a smaller length than the first periodicity,
• wherein an interval between time resource groups related to the time resources is determined based on the first periodicity,
• wherein an interval between time resources within each time resource group is determined based on the second periodicity, and
• wherein the validity of the configuration information regarding the first signal is determined based on a location of a time resource on which the second signal is transmitted within a corresponding time resource group.
