The disclosure relates to a method performed by a UE in a wireless communication system. A method performed by a UE in a wireless communication system according to an embodiment may include receiving resource configuration information in a time domain for UL or DL in a plurality of BWPs from a BS, receiving information about an activated BWP from the BS, determining a UL resource or a DL resource in the time domain corresponding to the activated BWP based on the resource configuration information and the information about the activated BWP, and communicating with the BS based on the UL resource or the DL resource of the time domain corresponding to the activated BWP.

Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smartcars or connected cars, healthcare, digital education, small businesses, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A method of a terminal in a communication system, according to one embodiment of the disclosure, can comprise the steps of: receiving, from a base station, downlink control information (DCI) associated with sidelink transmission; confirming a preparation time associated with the sidelink transmission; and performing the sidelink transmission on the basis of the DCI if a first timing associated with the sidelink transmission determined on the basis of the DCI is after the preparation time from a second timing associated with the DCI reception.

A base station (BS) may establish communication with a first user equipment device (UE). The BS may determine a transmission direction for each of a plurality of symbols included in one or more slots. The BS may transmit a slot format indicator (SFI) to the UE. The SFI may indicate the transmission direction for each of the plurality of symbols included in one or more slots. The BS and the UE may perform communication during the one or more slots according to the determined transmission direction.

Embodiments of the present application provide a wireless communication method and device. The method may include: a terminal device determines at least one time domain resource unit occupied by SRS transmission over an SRS resource; the terminal device determines a resource utilization mode used for transmitting the SRS on the at least one time domain resource unit; the terminal device performs, according to the determined resource utilization mode, the SRS transmission on the at least one time domain resource unit.
