摘要： The present disclosure relates to a 5G or a pre-5G communication system for supporting higher data transmission rates in a beyond-4G communication system, such as LTE. Particularly, the present disclosure relates to a method for a base station in a wireless communication system, the method comprising the steps of: transmitting, to a terminal, information for short transmission time interval, STTI; transmitting, to the terminal, a timing advance for the terminal, wherein a range of the timing advance is associated with the information for the STTI; and transmitting, to the terminal, a signal based on the information for the STTI.

摘要： The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and safety related service, or the like) on the basis of a 5G communication technology and an IoT related technology. The present invention relates to a wireless communication system. More specifically, disclosed is a method and apparatus for transmitting a control signal associated with uplink data transmission by a terminal when the terminal performs uplink transmission.

摘要： The present disclosure relates to a method performed by a user equipment in a wireless communication system, the method comprising: receiving, from a base station, a system information block, SIB; transmitting, to the base station, a random access preamble for a random access procedure; identifying application information of a transform precoding for a first physical uplink shared channel, PUSCH, transmission based on the SIB, wherein the first PUSCH transmission is scheduled by a random access response, RAR, received as a response to the random access preamble; performing the first PUSCH transmission, to the base station, according to a result of the identification based on the SIB; identifying UE-specific application information of a transform precoding for a second PUSCH transmission based on a radio resource control, RRC, message; and performing the second PUSCH transmission, to the base station (500), according to a result of the identification based on the RRC message. In case that the UE-specific application information of the transform precoding for the second PUSCH transmission is not included in the RRC message, the second PUSCH transmission is performed based on the application information of the transform precoding for the first PUSCH transmission.
