Abstract: The present disclosure relates to a method and apparatus for performing random access in a user equipment for a small cell e-NB with a small cell service area in heterogeneous e-NB cell carrier integration (dual connectivity or inter-eNB carrier aggregation) in mobile communication systems. In accordance with an aspect of the present disclosure, a method for performing random access in a mobile communication system is provided. The method includes receiving a configuration request message for configuring a Serving Cell Group (SCG) from a second eNB located in a service area of a first eNB through the first eNB; configuring an SCG cell based on the configuration request message, and sending a configuration response message in response to the configuration request message to the second eNB through the first eNB; and performing random access if there is uplink data present on a logic channel (LCH) relocated into the SCG cell.

Abstract: Disclosed are: a communication technique for fusing, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4 G system and subsequent systems; and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service and the like) based on 5G communication technology and IoT related technology. The present disclosure presents a method by which a base station determines the approximate location of a terminal on the basis of a reception power report, and sets a codebook subset on the basis of the approximate location of the terminal so as to reduce a channel state report burden.

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 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. A method for performing communication using an unlicensed band includes reserving a channel of the unlicensed band using a control frame supporting WLAN by a WLAN module, when reserving the channel of the unlicensed band succeeds, determining whether the channel of the unlicensed band is used by a mobile communication module, and transmitting data supporting the unlicensed band through the reserved channel of the unlicensed band.

Abstract: method is provided for communicating with a User Equipment (UE) supporting a High Power Saving Reception Mode (HPSRM) mode by an evolved Node B (eNB) in a wireless communication system. The method includes receiving Discontinuous Reception (DRX) cycle information from a network entity performing mobility management for the UE by the eNB communicating with the UE over a wireless link; and broadcasting system information including the DRX cycle information. The DRX cycle information is set longer than DRX cycle information of a UE non-supporting the HPSRM mode. By doing so, an efficient paging method for an UE operating in the HPSRM mode may be provided.
