    摘要: A ranging method and apparatus in a wireless communication system are provided. The ranging method of a Mobile Station (MS) includes selecting at least one Base Station (BS) for performing ranging, transmitting a ranging signal by using a common ranging region shared by a plurality of BSs, and receiving a response signal, including a ranging result of at least one BS which received the ranging signal, from a central controller.

    摘要: 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). According to various embodiments, an apparatus of a user equipment (UE) in a wireless environment comprises at least one transceiver; and at least one processor operably coupled to the at least one transceiver. The at least one transceiver is configured to receive a reference signal configuration comprising information for indicating whether a reference signal of a transmission and reception point (TRP) is transmitted through beam sweeping from the TRP, and receive the reference signal from the TRP based on the received reference signal configuration.

    摘要: 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 for communicating by a user equipment with a macro cell base station and a small cell base station in a communication system is provided. The method comprises applying a first base station security key to a first communication link with the macro cell base station; generating a second base station security key to be used for a second communication link with the small cell base station based on the first base station security key; applying the second base station security key to the second communication link with the small cell base station; and communicating through at least one of the first communication link and the second communication link.

    摘要: 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 LTE. Disclosed are: a method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel; and a mobile communication system, and according to an embodiment of the present disclosure, the method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel comprises the steps of: reducing the counter and performing a CCA for the channel, during a first period of transmitting a discovery signal and data; storing the reduced counter when a second period of transmitting only the discovery signal without the data is started; reducing the counter by using the stored counter and performing the CCA for the channel when a third period of transmitting the discovery signal and the data is started; and transmitting the discovery signal or the data on the channel on the basis of the counter value.
