Abstract: The present invention relates to a method and an apparatus for controlling mobility for a cell having a small cell service area in a mobile communication system. A method for controlling mobility of a terminal in a mobile communication system, according to one embodiment of the present invention, can comprise the steps of: performing, by the terminal, a measurement operation; transmitting a measurement result to a base station; determining whether or not a target cell for handover is a cell for which handover is allowed; and skipping the handover if the target cell for handover is the cell for which handover is not allowed. According to one embodiment of the present invention, when the small cells are arranged sparsely or in the form of a cluster within a service area of a macro cell, the possibility of a handover failure can be reduced, and if a radio link failure occurs when handover is omitted, re-connection can be performed quickly by the terminal.

Abstract: The present disclosure relates to a communication technique for converging IoT technology and a 5G communication system for supporting higher data transmission rate after a 4G system, and a system thereof. The present disclosure can be applied to an intelligent service (for example, a smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety related service etc.) based on 5G communication technology and IoT related technology. The present invention relates to a signal receiving method and apparatus of a terminal in device-to-device wireless communication. In the present invention, a D2D reception terminal can measure a DM RS transmitted together with a PSBCH or detect energy with respect to the entirety of or a part of a symbol region through which the PSBCH or DM RS in a synchronization subframe can be transmitted so as to enable use as a criterion for determining whether to retry PSBCH decoding. When a DM RS measurement level or an energy detecting level is larger than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has been transmitted and may retry the PSBCH decoding for a certain time or a certain number of times. When a DM RS measurement level or an energy detecting level is smaller than a certain threshold value, the D2D reception terminal recognizes that the PSBCH has not been transmitted and may not retry the PSBCH decoding. When the PSBCH decoding is not retried, the D2D reception terminal can try other PSSS/SSSS detection. Through the present invention, the D2D reception terminal can avoid inefficient operation of retrying the PSBCH decoding for a certain time or a certain number of times despite non-transmission of the PSBCH.

Abstract: The present invention provides a method for controlling access of a terminal if the terminal accesses from a wireless LAN network to a mobile communication network, when the mobile communication network (for example, UMTS, LTE and the like) and the wireless LAN network are linked in a wireless communication system. Furthermore, the present invention provides a method for transmitting information on connectable peripheral wireless LAN networks. Thus, the present invention can reduce a load of a network since the network can control the access of a terminal, and can reduce unnecessary power consumption and solve a connection delay problem by providing a valid wireless LAN network list to the terminal.

Abstract: The present 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 and an apparatus that may repeatedly transmit signals to cope with and reduce transmission errors in device-to-device (D2D) communication are provided. The method includes receiving, upon generation of data to be transmitted to a receiving user equipment (UE) (RX UE), allocation of resources to be used for D2D communication, transmitting a scheduling assignment (SA) containing identification information of at least one RX UE to the at least one RX UE, assigning at least one hybrid automatic repeat request (HARQ) process for the identification information of the at least one RX UE, and transmitting data to the at least one RX UE based on the HARQ process. Accordingly, it is possible to remove factors causing system performance degradation when retransmission operation for communication between a UE and a base station (eNB) is introduced to D2D communication.
