The method may include: initiating a sidelink service with a second apparatus (9020) based on a specific cast type; and transmitting information on the specific cast type related to the sidelink service. ## Claims ### Claim 1 A method for performing sidelink communication by a first apparatus, the method comprising: receiving, from a second apparatus, sidelink capability information related to the second apparatus; transmitting, to a base station (BS), a radio resource control (RRC) message including (i) the sidelink capability information received from the second apparatus, (ii) cast type information related to the sidelink communication with the second apparatus, and (iii) synchronization reference information related to the sidelink communication with the second apparatus; and performing the sidelink communication based on the RRC message, wherein the cast type information includes information related to unicast, groupcast or broadcast. ### Claim 2 (depends on 1) The method of claim 1, wherein the synchronization reference information includes information related to a global navigation satellite system (GNSS), a base station (BS) or a user equipment (UE). ### Claim 3 (depends on 1) The method of claim 1, wherein the RRC message includes quality of service (QoS) information including sidelink communication range information related to the sidelink communication. ### Claim 4 (depends on 3) The method of claim 3, wherein the QoS information includes priority information related to the sidelink communication and delay budget information related to the sidelink communication. ### Claim 5 (depends on 3) The method of claim 3, wherein the QoS information includes at least one QoS indicator value representing guaranteed bit rate (GBR) or non-GBR. ### Claim 6 (depends on 1) The method of claim 1, wherein the sidelink communication is related to a destination identifier (ID). ### Claim 7 (depends on 1) The method of claim 1, wherein the sidelink communication with the second apparatus is performed based on the unicast, the groupcast or the broadcast indicated by the cast type information. ### Claim 8 (depends on 1) The method of claim 1, wherein the RRC message is a sidelink UE information message. ### Claim 9 (depends on 1) The method of claim 1, wherein the RRC message includes information related to resources for the sidelink communication. ### Claim 10 (depends on 9) The method of claim 9, wherein the resources for the sidelink communication is allocated by the BS based on the RRC message. ### Claim 11 (depends on 1) The method of claim 1, wherein the RRC message includes channel status information includes channel busy ratio (CBR) that is measured by the second apparatus. ### Claim 12 (depends on 1) The method of claim 1, further comprising: receiving, from the BS, information on allowed interface including at least one of PC5 interface or Uu interface. ### Claim 13 (depends on 1) The method of claim 1, wherein the first apparatus (9010) or the second apparatus (9020) includes at least one of a terminal, a user equipment (UE), a wireless device, a wireless communication device, a vehicle, a vehicle equipped with an autonomous driving function, a connected car, a unmanned aerial vehicle (UAV), an artificial intelligence (AI) module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, a mixed reality (MR) device, a hologram device, a public safety device, a machine type communication (MTC) device, an internet of things (IoT) device, a medical device, a pin-tech device (or financial device), a security device, or a climate/environmental device. ### Claim 14 A first apparatus performing sidelink communication, the first apparatus comprising: one or more memories storing instructions; one or more transceivers; and one or more processors operably connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to: receive, from a second apparatus, sidelink capability information related to the second apparatus; transmit, to a base station (BS), a radio resource control (RRC) message including (i) the sidelink capability information received from the second apparatus, (ii) cast type information related to the sidelink communication with the second apparatus, and (iii) synchronization reference information related to the sidelink communication with the second apparatus; and perform the sidelink communication based on the RRC message, wherein the cast type information includes information related to unicast, groupcast or broadcast. ### Claim 15 An apparatus configured to control a first user equipment (UE) to perform sidelink communication, the apparatus comprising: one or more processors; and one or more memories operably connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to: receive, from a second UE, sidelink capability information related to the second UE; transmit, to a base station (BS), a radio resource control (RRC) message including (i) the sidelink capability information received from the second UE, (ii) cast type information related to the sidelink communication with the second UE, and (iii) synchronization reference information related to the sidelink communication with the second UE; and perform the sidelink communication based on the RRC message, wherein the cast type information includes information related to unicast, groupcast or broadcast.
