    Abstract: A method and apparatus is capable of encrypting short data in a wireless communication system When a terminal generates a short data burst in idle mode, the apparatus generates a Traffic Encryption Key (TEK) using a Cipher-based Message Authentication Code (CMAC)-TEK prekey derived from an Authorization Key (AK) related to Security Association (SA) between the terminal and a Base Station (BS). A nonce is constructed with a Packet Number (PN) identical to an uplink CMAC PN (CMAC-PN_U) transmitted together with a Ranging Request (RNG-REQ) message carrying the short data burst The short data burst is encrypted using the TEK and the nonce. A Medium Access Control (MAC) Protocol Data Unit (PDU) is generated by attaching a MAC header and a CMAC digest for integrity protection to the RNG-REQ message carrying the encrypted short data burst. The MAC PDU is transmitted to the BS.

    Abstract: Provided is a method for managing a security key for communication authentication with a Mobile Station (MS) in a communication system. The method includes acquiring a first authentication key by performing an authentication procedure for the communication authentication in a cloud cell having member Base Stations (BSs) that include a master BS and at least one slave BS for providing a service to the MS; and communicating with at least one member BS using a first encryption key that is generated using the first authentication key.

    Abstract: The present invention is a method for transmitting a data packet by a user terminal in a mobile communication system. The method enters a power saving mode for transmitting the data packet only if a channel state satisfies a transmission threshold value, compares the index indicating the channel state and the transmission threshold value upon occurrence of a data packet to be transmitted, starts transmission of the data packet if the index indicating the channel state is greater than the transmission threshold value, and proceeds with the transmission of the data packet until the time set by the timer that starts at the same time as the transmission of the data packet expires.

    Abstract: A communication method in a wireless communication system supporting device-to-device (D2D) communication is provided. The communication method includes transmitting a first message including information for identifying a relay to discover a relay user equipment (UE) that performs a relay function in the D2D communication, and receiving a second message including information about the relay UE that performs the relay function, from the relay UE that has received the first message, the second message being transmitted in response to the first message.
