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

An electronic device which performs data communication with a plurality of access point (APs) through joint transmission, the electronic device comprising:

• a communication interface;
• a processor configured to control the electronic device and be electrically connected with the communication interface;
• and
• a memory configured to store instructions that, when executed by the processor, cause the processor to:
• search for APs to retrieve a plurality of APs,
• determine a modulation and coding scheme (MCS) for data transmission based on a signal strength of at least two APs among the plurality of APs,
• determine 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,
• control the communication interface to transmit information about the candidate APs to an AP control device, and
• control the communication interface to perform data communication with joint APs, which are determined to perform joint transmission by the AP control device, among the candidate APs.
