Abstract: The present disclosure provides a method for transmitting a synchronization signal (SS), the method comprising: performing a listen-before-talk (LBT) operation in a pre-defined window; if the LBT operation succeeds, transmitting an SS block (SSB) in the window, wherein the SSB comprises the SS, or the SSB comprises the SS and a physical broadcast channel (PBCH). Compared with the prior art, the present disclosure may significantly improve the efficiency of data transmission and the access performance for the communication system by relaxing the time when the base station implements the LBT, that is, allowing the base station to implement the LBT in the pre-defined window and transmit the SSB after the LBT succeeds.

Abstract: A method of operating a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a new radio (NR) base station, first downlink control information (DCI) for scheduling of a long term evolution (LTE) sidelink (SL); and performing, based on the first DCI, a transmission of the LTESL, wherein the first DCI is scrambled by an LTE-SL-vehicle to everything (V2X)-radio network temporary identity (V-RNTI), and wherein the LTE-SL-V-RNTI is used to activate or deactivate a semi-persistently scheduled SL transmission.

Abstract: A method and device are provided for determining resource configuration of uplink signal transmission. A method performed by a terminal in a wireless communication system includes receiving, from a base station, a first control message including first configuration information on msg3 repetition, second configuration information on UL or DL configuration, and third configuration information on an SSB; transmitting, to the base station, a random access preamble; receiving, from the base station, an RAR in response to the random access preamble; identifying a first resource for a repetition of a msg3 transmission based on the RAR and the first control message, wherein the first resource does not include a symbol indicated as a downlink by the second configuration information or a symbol indicated by the third configuration information to which the SSB is to be transmitted; and transmitting, to the base station, the msg3 on the identified first resource.
