Abstract:
A method for performing communication by a first communication device in a mobile communication system is provided. The method includes determining whether the first communication device is proximate to a nearby second communication device through a short-range communication link, enabling one of a first long-range communication link with a network or the short-range communication link with the second communication device based on the determination as to whether the first communication device is proximate to the second communication device, and receiving data from the network through the enabled one of the first long-range communication link with the network or the short-range communication link.
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 LTE, and subsequent systems. Provided is a random access preamble transmitting method of a terminal for performing an initial access in a communication system, the method comprising the steps of: acquiring system information from a base station; determining a repetition level of a random access preamble by using the acquired system information; and transmitting the random access preamble with a repetitive frequency corresponding to the repetition level in a transmission resource area corresponding to the determined repetition level.
Abstract:
A processor includes a security level determining unit and a variable pipeline. The security level determining unit determines a security level of first data to be processed by the processor. The variable pipeline receives the first data, generates original data by performing a decryption operation on the first data during a total number of one or more clock cycles corresponding to the security level determined by the security level determining unit, and processes the original data.

A method and apparatus for selecting a wireless Local Area Network (LAN) within a cell to be accessed by a User Equipment (UE) in a mobile communication system are provided. The method includes performing, when a request for information regarding wireless LAN Access Points (APs) within the cell is received, a search for the wireless LAN APs and transmitting a report indicating a search result to a serving Evolved Node B (ENB); receiving, from the serving ENB, updated information on wireless LAN APs based on report indicating the search result; determining whether to perform a re-search for the wireless LAN APs based on the updated information on the wireless LAN APs; and performing, in response to determination to perform the re-search for the wireless LAN APs, the re-search and selecting APs to be accessed based on a result of the re-search.
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 long term evolution (LTE). Disclosed is a method by which a terminal transmits a buffer status report (BSR) in a communication system, including allocating an uplink resource from a base station; comparing the number of padding bits with a value obtained by summing the size of the BSR and the size of a sub-header of the BSR; and transmitting, to the base station according to the comparison result, the BSR including information indicating the presence or absence of a field representing a buffer size for at least one logical channel group (LCG).
