    Abstract: Disclosed is a method for transmitting and receiving a signal for a terminal to perform a random access channel procedure (RACH Procedure) in an unlicensed band. In particular, the method comprises: receiving a synchronization signal/physical broadcast channel block (SS/PBCH block); obtaining system information from a PBCH included in the SS/PBCH block; sending a first physical random access channel (PRACH) preamble through a message A on the basis of the system information; and receiving a random access response (RAR) through a message B related to contention resolution in response to the message A, wherein the first PRACH preamble is a PRACH preamble mapped to a physical uplink shared channel (PUSCH) occasion for the message A, and a window for reception of the message B may start after at least one symbol from the last symbol of the PUSCH occasion.

    Abstract: Disclosed herein are a method and a device for transmitting and receiving uplink data in a wireless communication system. According to the present disclosure, a UE may transmit to a base station information related to a capability of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive Downlink Control Information (DCI) for transmitting the uplink data from the base station and the DCI may include a TPMI used for the UE to transmit the uplink data. Thereafter, the UE may transmit to the base station the uplink data by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.

    Abstract: The present disclosure provides a method for reporting positioning information by a terminal in a wireless communication system. Specifically, the method comprises: receiving information relating to a plurality of positioning reference signal (PRS) resource sets including a plurality of PRS resources; measuring each of the plurality of PRS resources to acquire pieces of positioning information; and reporting at least one piece of positioning information and information relating to a PRS resource for the at least one piece of positioning information, among the pieces of the positioning information.
