A control method of an electronic device for performing joint transmission is provided. The control method includes searching for access points (APs) to retrieve a plurality of APs, determining a modulation and coding scheme (MCS) for data transmission based on a signal strength of at least two APs among the plurality of APs, determining the at least two APs as candidate APs for joint transmission by comparing a joint transmission gain time according to the determined MCS and a synchronization time for the at least two APs to perform joint transmission, transmitting information about the candidate APs to an AP control device, and performing data communication with joint APs, which are determined to perform joint transmission by the AP control device, among the candidate APs.

Electronic device and method for controlling the electronic device for joint transmission thereof

The present disclosure relates to a communication scheme for combining an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to a smart service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and security related service, or the like) on the basis of a 5G communication technology and an IoT related technology. A timing advance controlling method according to the present disclosure comprises the steps of: selecting a cell on the basis of a signal received from a base station; selecting one coverage class from a plurality of coverage classes in the selected cell; selecting one timing advance value from a plurality of timing advance values determined in advance on the basis of the selected coverage class; and determining an uplink transmission point on the basis of the selected timing advance value, and transmitting uplink data at the determined transmission point.

Method and apparatus for controlling timing advance

The present disclosure relates to a 5Generation (5G) or pre-5G system to be provided to support a higher data transfer rate after a 4G communication system such as Long Term Evolution (LTE). The present invention is for performing random access in a wireless communication system, and a base station includes a communication unit for transmitting system information including a plurality of thresholds, and a control unit for determining a random access result for each mode on the basis of a detection result on a preamble transmitted from at least one terminal.

Method and device for performing random access in wireless communication system

A method of declaring and using variables includes; determining whether variables are independent variables or common variables, declaring and storing the independent variables in a plurality of data structures respectively corresponding to the plurality of processors, declaring and storing the common variables in a shared memory area, allowing each one of the plurality of processors to simultaneously use the independent variables in a corresponding one of the plurality of data structures, and allowing only one of the plurality of processors at a time to use the common variables in the shared memory area.

Multi-processor system device and method declaring and using variables

A method and apparatus for providing an interactive service and a method and apparatus for performing communication are provided. An Open Cable Application Platform (OCAP) application may be directly executed in at least one broadcasting receiving apparatus by determining whether an application for providing the interactive service is independently executable using middleware installed in the broadcasting receiving apparatus and selectively requesting a set-top box to provide data needed for executing the application based on the determination result.
