Abstract: The present disclosure provides a method for transmitting and receiving a sidelink synchronization signal (SLSS) in a wireless communication system. In detail, the method performed by a first terminal includes receiving configuration information related to the SLSS; receiving the SLSS from a second terminal; determining whether the received SLSS is an SLSS related to sidelink communication or an SLSS related to sidelink discovery based on the received configuration information; and transmitting the received SLSS when the received SLSS is the SLSS related to sidelink discovery. Through this, the method proposed in the present disclosure has the effect of reducing unnecessary battery consumption of the first terminal and minimizing interference in the terminals of the neighboring cell.

Abstract: The present application discloses a method for allocating resources for direct communication between terminals in a wireless communication system. Specifically, the method for allocating resources comprises: a step of configuring a first periodic resource so as to transmit multiple messages via direct communication between the terminals; and a step of transmitting the multiple messages by using the first periodic resource if a coding rate corresponding to the first periodic resource is below a maximum coding rate configured by an upper layer, wherein, if the coding rate is equal to or above the maximum coding rate, the first periodic resource is released and a second periodic resource is configured.

Abstract: A sensing gap is configured among cells for inter-cell interference coordination (ICIC) mechanism. A network node listens on a reservation signal in the sensing gap from a neighbor cell, and upon listening on the reservation signal, performs downlink (DL) transmission to a user equipment (UE) or uplink (UL) reception from the UE in a cell.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes receiving radio access network (RAN) paging by the Tx UE, initiating a radio resource control (RRC) resume procedure by the Tx UE, and transmitting an RRC message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.

Abstract: Proposed is a method of performing wireless communication by a first apparatus. The method may include receiving first control information on a first search space related to the first control information, and receiving second control information on a second search space related to the second control information. For example, the first search space related to the first control information may overlap with the second search space related to the second control information, based on that a base station allocates a resource related to sidelink transmission to the first apparatus in a carrier in which Uu communication is performed.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes transmitting a physical sidelink shared channel (PSSCH) to a second UE by the first UE, and transmitting, to a base station (BS), feedback information based on a physical sidelink feedback channel (PSFCH) for the PSSCH on a physical uplink control channel (PUCCH) by the first UE. A transmission timing of the PUCCH is determined based on information about the number of slots from the PSFCH to the PUCCH.

Abstract: A method and apparatus for a sidelink of a wireless communication system are proposed. A transmission UE can contiguously or non-contiguously allocate radio resources through sidelink communication. A specific resource allocation method is selected in consideration of latency of sidelink data/packets or other factors. For example, a specific resource allocation method can be determined based on whether a plurality of contiguous subchannels is allocated to radio resources before a first time, which is determined based on latency of data/packets.
