1. An electronic device comprising:
at least one processor, and
memory storing instructions which, when executed by the at least one processor individually or collectively, cause the electronic device to:
while being connected to a first cell based on a first radio access technology (RAT), receive, at a first point in time, at least one message causing a random access (RA) procedure for a second cell based on a second radio access technology (RAT) different from a first RAT to perform a dual-connectivity of the first cell and the second cell,
identify, based on the reception of the at least one message, a first accumulative specific absorption rate (SAR) having occurred based on transmission of at least one radio frequency (RF) signal based on the first RAT and/or the second RAT for a first time interval before the first point in time,
transmit an RA preamble message to the second cell based on determining, based on the first accumulative SAR, that performing the RA procedure for the second cell to perform the dual-connectivity of the first cell and the second cell is possible, and
refrain from transmitting the RA preamble message based on determining, based on the first accumulative SAR, that performing the RA procedure for the second cell to perform the dual-connectivity of the first cell and the second cell is impossible.
