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: Methods and devices are provided for transmitting and receiving hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a wireless communication system. Higher layer signaling is received that includes at least one of information indicating whether to apply HARQ-ACK spatial bundling to HARQ-ACK information to be transmitted on a physical uplink control channel (PUCCH) or information indicating whether to apply HARQ-ACK spatial bundling to HARQ-ACK information to be transmitted on a physical uplink shared channel (PUSCH). At least one HARQ-ACK information bit corresponding to downlink data received in at least one cell, is determined based on the higher layer signaling. HARQ-ACK information corresponding to the determined at least one HARQ-ACK information bit is transmitted on at least one of the PUCCH or the PUSCH.

Abstract: The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method for operating a terminal is provided. The method includes detecting, scheduling assignment (SA) of another terminal in a sensing window based on transmission time intervals (TTIs) with different lengths in a resource pool; detecting a receiving power of a scheduled data channel based on the SA and a receiving energy of each sub-channel of each subframe; determining resources for data transmission based on the SA, the receiving power and the receiving energy; and transmitting data on the resources.

Abstract: Embodiments of the present disclosure provide a method for transmitting data, including: sensing, by a first device, a scheduling assignment (SA) of another device; measuring a received power of the other device, and measuring a total received energy of a subframe/subband; determining a received power reference value and a total received energy reference value of the other device according to the SA; selecting resources; and transmitting data using the selected resources. According to the method of the present disclosure, the performance of the method which avoids collision based on SA is improved, and measurement accuracy of the total received energy of the subband is increased. Thus, resource selection/re-selection can be performed better. As such, interferences between devices can be avoided effectively.

Abstract: Provided are a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), with a transmission and receipt processing method and device for time-frequency synchronization between V2X terminals. When a synchronization signal to be transmitted is identical to a synchronization signal of an existing D2D terminal, time-frequency resources configured for the D2D terminal in a cell are reused to transmit the synchronization signal. When synchronization signal to be transmitted is different from a synchronization signal of an existing D2D terminal, reconfigured time-frequency resources are used to transmit the synchronization signal. The synchronization signal transmitted by a V2X terminal indicates a corresponding synchronization source type by using a value of an SLSS sequence index and/or a value of a PSBCH specified field.
