    Abstract: Provided is a method and apparatus for performing a Wireless Fidelity (WiFi) handoff through coordination in a wireless communication system. A first access point (AP) device that transmits a first Bluetooth Low Energy (BLE) advertising packet sets a transmission period identically for the first BLE advertising packet and a second BLE advertising packet, determines transmission timings of the first BLE advertising packet and the second BLE advertising packet, transmits a setting message comprising information about the set transmission period of the second BLE advertising packet and information about the determined transmission timing of the second BLE advertising packet to the second AP device, transmits the first BLE advertising packet to a terminal, and performs a WiFi connection with the terminal, based on a determination by the terminal.

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates than 4G systems such as LTE. More specifically, disclosed are a method and device pertaining to generating and detecting a random access preamble signal for random access in ultra-high frequency band wireless communication. A terminal according to an embodiment disclosed herein comprises a transmission and reception unit and a control unit, wherein the control unit is configured to: generate a preamble signal; transmit the preamble signal to a base station; and receive a random access response including timing advance (TA) information from the base station in response to the transmission of the preamble signal, wherein the preamble signal may include a first signal portion related to a first sequence, and a second signal portion related to a guard time and a second sequence.

    Abstract: A communication method using a plurality of channels in a wireless communication system supporting an unlicensed band. The communication method includes: performing listen-before-talk (LBT) for transmitting a random access preamble on each of a plurality of control channels supported by a user equipment (UE), from among a plurality of control channels supported by a base station; transmitting a random access preamble through a control channel where the LBT succeeded from among the plurality of control channels where the LBT for transmitting the random access preamble is performed; and receiving a random access response (RAR) through a control channel determined according to a result of the LBT performed by the base station, from among the plurality of control channels supported by the UE, wherein a control channel is a channel through which a control signal and a data signal are transmitted and received.

    Abstract: A 5th generation (5G) or a pre-5G communication system to support a higher data transmission rate than a system after a 4th generation (4G) communication system such as long-term evolution (LTE) is provided. A method of determining a carrier sense threshold by one source terminal in a wireless communication system is provided. The method includes identifying whether one or more interferer terminals and one or more destination terminals exist for one source terminal, and if the terminals exist, determining a carrier sense threshold of each of the one or more interferer terminals and the one or more destination terminals based on an interference intensity received from the one or more destination terminals and a feedback link margin.

    Abstract translation: 提供第五代（5G）或前5G通信系统，以支持比在诸如长期演进（LTE）的第四代（4G）通信系统之后的系统更高的数据传输速率。 提供了一种在无线通信系统中由一个源终端确定载波检测阈值的方法。 该方法包括：识别一个或多个干扰源终端和一个或多个目的地终端是否存在于一个源终端，并且如果存在终端，则确定一个或多个干扰源终端和一个或多个目的终端中的每一个的载波检测阈值 根据从一个或多个目的地终端接收的干扰强度和反馈链路余量。
