Abstract: The present disclosure relates to a communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to 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 service, or the like) based on the 5G communication technology and the IoT related technology. The disclosure relates to a method for recovering a beam into a correct beam according to a position of a terminal using a non-contention-based and contention-based beam failure recovery method in order to recover a beam failure in which communication is disconnected due to movement of a terminal or the like in a wireless communication system performing beam-based communication services.

Abstract: Methods and apparatuses are provided in a wireless communication system. A service data unit (SDU) is received from an upper layer. A protocol data unit (PDU) including a header for the SDU is generated based on an expiry of a timer for the SDU or an indication obtained from the upper layer. The PDU including the header is delivered to a lower layer. The PDU includes only the header and does not include a payload.

Abstract: The present disclosure relates to 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). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method by a user equipment (UE) in a wireless communication system includes reselecting another equivalent public land mobile network (PLMN) in an inactive state, transmitting, to a base station, a radio resource control (RRC) resume request message including a resume cause configured to mobile originated (mo)-signaling in case that a radio access network (RAN)-based notification area update procedure is triggered, and receiving, from the base station, an RRC resume message.

Abstract: The disclosure relates to a communication technique and a system thereof that fuses a 5G communication system for supporting higher data rate after a 4G system. The disclosure is enabled to be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services, etc.) based on 5G communication technology and IoT related technology. A method for performing a random access by a terminal is provided. The method includes receiving information for performing a random access from a base station (BS), determining a frequency band to perform the random access among a first frequency band and a second frequency band based on the information for performing the random access, and transmitting a first random access preamble to the BS on the determined frequency band.

Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as an LTE. A method of a terminal according to the present invention comprises: receiving a signal from a primary cell by using a first RF chain and receiving a signal from a second cell by using a second RF chain; deactivating the secondary cell in case of receiving a message for indicating a handover from the primary cell; performing a synchronization with a target cell by using the second RF chain while transmitting and receiving a signal with the primary cell by using the first RF chain; and receiving the signal from the target cell by using the second RF chain after performing the synchronization.
