Abstract: An electronic device may include: a communication processor; and an application processor configured to transmit data to be transmitted through first cellular communication and/or second cellular communication to the communication processor, wherein the communication processor includes: a PDCP configured to support a split bearer for transmitting split data ; a first RLC configured to split data received from the PDCP ; and a second RLC configured to split data received from the PDCP , wherein the PDCP is configured to receive data to be transmitted through the first cellular communication and/or the second cellular communication from the application processor, transmit the data to at least one of the first RLC or the second RLC, and stop transmitting the data to the RLC receiving the data, based on a result of comparison between the size of data temporarily stored in the RLC receiving the data with a first configuration value.
