Abstract: A base station is provided. The base station transmits multiple data in a first subframe, receives response signals corresponding to the multiple data, determines a ratio of negative acknowledge (NACK) signals to the response signals, and adjusts or maintains a contention window based on the determined ratio. The present disclosure relates to communication schemes for combining 5th-generation (5G) communication systems with internet of things (IoT) technology to support higher data transmission rate as post-4th-generation (post-4G) systems and systems for the same. The present disclosure may be used in intelligent services (e.g., smart home, smart building, smart city, smart car, or connected car, health-care, digital education, retail business, security and safety-related services, etc.) based on the 5G communication technology and IoT-related techniques.

Abstract: A 5th Generation (5G) or pre-5G communication system for supporting higher data transmission rates beyond 4th Generation (4G) communication systems such as long term evolution (LTE) systems. A method for transmitting download control information in a communication system is provided. The method includes configuring the control information indicating at least one control channel element (CCE) including at least one resource element group (REG) unit interleaved based on the interleaving information indicated by a higher layer signaling; and transmitting, to a user equipment (UE), the configured control information.

Abstract: A method, provided by the present disclosure, of transmitting a reference signal by a base station in a wireless communication system using a plurality of antenna ports including mapping wireless resources, for transmitting a reference signal, to a plurality of antenna ports for transmitting the reference signal; and using the wireless resources and transmitting the reference signal to a terminal through the mapped antenna ports. The mapping to the antenna ports is executed on the basis of a combination of a first mapping pattern between the wireless resources and the antenna ports and a second mapping pattern between the wireless resources and the antenna ports.

Abstract: Disclosed is a method for controlling a security mode by a user equipment (UE) in a wireless communication system, including performing a camp-on process and a cell update process with a network when an out-of-service (OOS) situation has occurred, receiving one of a signaling connection release (SCR) message and a first protocol data unit (PDU) which corresponds to the SCR message from the network, receiving a security mode command (SMC) message from the network if the SCR message is received, performing an integrity process on the SCR message using an old security configuration, and performing a rollback process to discard a new security configuration included in the SMC message if a result of the integrity process result an integrity check success, and updating a security configuration to the old security configuration.

Abstract: Provided herein are communication schemes for combining 5G communication systems with IoT technology to support higher data transmission rate as post-4G systems and systems for the same. The present disclosure may be used in intelligent services (e.g., smart home, smart building, smart city, smart car, connected car, health-care, digital education, retail business, security and safety-related services) based on the 5G communication technology and IoT-related techniques. According to an embodiment of the present disclosure, a method for sensing a channel by a base station in a communication system comprises setting a channel sensing interval for sensing a channel available on an unlicensed band, based on a first start time when the base station starts a signal transmission and the set channel sensing interval, setting a second start time when a channel sensing operation starts, and performing the channel sensing operation during the channel sensing interval from the set second start time.
