Abstract: Provided is a method performed by a user equipment (UE) in a wireless communication system including receiving a downlink signal, filtering the downlink signal, sampling the filtered downlink signal, performing differential decoding on the sampled downlink signal, obtaining a primary synchronization signal (PSS) sequence based on the downlink signal on which the differential decoding is performed, and obtaining cell area information based on the PSS sequence obtained based on the downlink signal on which the differential decoding is performed.

Abstract: Provided is a method performed by a UE in a wireless communication system including receiving at least one synchronization signal from a base station (BS), receiving system information from the BS, receiving a radio resource control (RRC) message from the BS, wherein the RRC message includes information on a number of data allocation offset index group candidates related to a data allocation offset, receiving downlink control Information (DCI) from the BS, wherein the DCI includes information on a data allocation offset index related to the data allocation offset.

Abstract: Provided are a method by which a transmission terminal performs groupcast transmission in a wireless communication system, and a device. The method transmits a synchronization signal block (SSB) through an SSB beam, receives, from each of a plurality of terminals, a discovery message as a response to the SSB, determines a groupcast transmission timing for specific terminals from among the plurality of terminals on the basis of the discovery message, transmits, to the specific terminals, a group transmission/reception timing message indicating the groupcast transmission timing, and performs groupcast transmission for the specific terminals by using the SSB beam at the groupcast transmission timing.

Abstract: The present disclosure relates to an operation method, by a first terminal in a wireless communication system, for providing a sidelink-based service in a wireless communication system. The method can comprise the steps of: transmitting, to a base station, information relating to a sidelink-based service provided by the first terminal; transmitting a discovery signal comprising information relating to the first terminal; receiving a response signal with respect to the discovery signal from a second terminal which has received the discovery signal; and establishing a connection with the second terminal to provide the service.

Abstract: The present disclosure is to sense a resource for sidelink communication in a wireless communication system. A method of operating a terminal in a wireless communication system may comprise receiving sidelink data through a physical sidelink shared channel (PSSCH) from another terminal and transmitting a feedback signal for the sidelink data through a physical sidelink feedback channel (PSFCH). The feedback signal may comprise hybrid automatic repeat request (HARQ)-acknowledge (ACK)/negative-ACK (NACK) information corresponding to the sidelink data and information related to a location of the PSSCH, and the feedback signal may be transmitted using a plurality of beams.

Abstract: Positioning is performed based on a signal from a terminal in a wireless communication system. A method of operating a terminal may comprise transmitting a first message requesting addition of a positioning reference signal (PRS) source to a base station, receiving, from the base station, a second message including information related to at least one other terminal to transmit a PRS, receiving at least one PRS transmitted by the at least one other terminal through a resource allocated by the base station, and performing an operation for positioning based on the at least one PRS.

Abstract: Provided is a method for operating a terminal in a wireless communication system, the method comprising: receiving, from a serving base station, a location request message including at least one of positioning reference signal (PRS) information of a neighbor base station and cell ID information of the neighbor base station; receiving a PRS of the serving base station from the serving base station; receiving a PRS from the neighbor base station based on the received location request message; estimating a location of the terminal based on the PRS received from the serving base station and the PRS received from the neighbor base station; and transmitting the estimated location of the terminal to the serving base station.
