According to an embodiment, it is assumed that the electronic device 400 is connected to the EN-DC environment. For example, the electronic device 400 may be connected to an eNB (eg, the eNB 445 of FIG. 4 ) and a gNB (eg, the gNB 440 of FIG. 4 ) through a split bearer.

According to an embodiment, in operation 710 , the electronic device 400 (eg, the first communication processor (eg, the first communication processor 212 of FIG. 2 )) may identify the amount of data to be transmitted. For example, the electronic device 400 includes data (eg, NR PDCP (eg, NR PDCP 602 , E-UTRA RLC 612 , and NR RLC 613 of FIG. 6 )) associated with at least one entity (eg, NR PDCP). : You can check the amount of data to be transmitted based on the amount of PDU (packet data unit), for example, at least one queue for at least temporarily storing data transmitted and/or received by each entity in memory (eg, a memory (not shown) included in the memory 130 of FIG. 1 or the first communication processor 212 of FIG. 2 ) may be allocated to at least a partial area. You can check the amount of transmission data stored in the queue of .For example, you can check the amount of data to be transmitted as the sum of the transmission data associated with the NR PDCP 602 , E-UTRA RLC 612 and NR RLC 613 . However, there is no limitation on the method of confirming the amount of data to be transmitted, for example, the amount of data may be confirmed based on the amount of data associated with an entity of another layer (eg, PHY entity, MAC entity). .

According to an embodiment, in operation 720, if the checked amount of data is greater than a threshold value (eg, 10 Mbyte), the electronic device 400 includes a plurality of transmission paths (eg, the first transmission path 580 of FIG. 5 and the second transmission path 580 of FIG. 5 ). 2) may be determined to transmit data using the transmit path 590). For example, the threshold may be initially set based on uplink data threshold information received from a network (eg, the eNB 445 ). For example, the electronic device 400 checks the uplink split threshold (ul-datasplitthreshold) included in the RRC connection reconfiguration message received from the network (eg, the eNB 445) during the procedure of accessing the EN-DC environment, and , it may be initially set as a threshold value. As another example, the threshold value may be initially set to a specified value stored in the memory of the electronic device 400 (eg, the memory 130 of FIG. 1 ). There is no limitation on the method of initially setting the threshold. According to an embodiment, the threshold may be updated. For example, the electronic device 400 may change the threshold value based on the amount of data to be transmitted and may transmit data based on the changed threshold value. According to an embodiment, the plurality of transmission paths (eg, the first transmission path 580 and the second transmission path 590 ) support different communication methods to transmit data, respectively. For example, the first transmission path 580 may transmit data to a gNB (eg, gNB 440 in FIG. 4 ) using a 5G network, and the second transmission path 590 may transmit data to an eNB (eg, gNB 440 in FIG. 4 ) using an LTE network.

For example, the electronic device 400 may set the maximum transmission power PcMax for each transmission path (eg, the first transmission path 580 and the second transmission path 590 ). For example, the electronic device 400 may set the maximum transmission power PcMax based on a setting value stored in a memory (eg, the memory 130 of FIG. 1 ). As another example, the electronic device 400 sets the maximum for each communication method included in at least one RRC connection reconfiguration message received from each of at least one base station (eg, gNB 440 and eNB 245 of FIG. 4 ). You can check the transmit power (PeMax). As another example, the electronic device 400 may use the SAR event maximum transmit power (SAR EVENT MAX Power) corresponding to each of the SAR events (eg, a grip event, a proximity event) stored in the memory 130 . The maximum transmit power (SAR Max) in consideration of the SAR backoff may be determined. According to an embodiment, the maximum transmission power of the electronic device may vary according to a communication method, but there is no limitation. For example, the maximum transmission power when the electronic device 400 uses the first communication method may be different from the maximum transmission power when the second communication method is used. According to an embodiment, when the electronic device 400 transmits data using both the first communication method and the second communication method, the electronic device 400 uses the second communication method according to the power to transmit data using the first communication method. The maximum transmit power for transmitting data may vary.

According to an embodiment, in operation 740 , the electronic device 400 may determine an amount of data to be transmitted and/or a data ratio based on the checked maximum transmission power using a plurality of transmission paths. For example, the electronic device 400 checks an uplink split threshold (ul-datasplitthreshold) included in the RRC connection reconfiguration message to determine the amount of data to be transmitted using the first transmission path 580 and/or the second transmission The amount of data to be transmitted may be determined using the path 590 , or a ratio of data to be transmitted through each transmission path may be determined.

A plurality of transmission paths (eg, the first transmission path 580 and the second transmission path 590 ) may support different communication schemes. For example, the first transmission path 580 may support a 5G network, and the second transmission path 590 may support an LTE network. For example, operation 830 may be the same as some of operation 720 described above. Detailed descriptions may be omitted to avoid duplication.

For example, the electronic device 400 may transmit data only through a transmission path associated with the main path of the split bearer. If the main path of the split bearer is set as the path associated with the gNB 440 , the electronic device 400 may transmit data using only the first transmission path 580 supporting communication with the gNB 440 . When the amount of data to be transmitted is small, it may be efficient for the electronic device 400 to transmit data using one transmission path.

According to an embodiment, the threshold value may be a criterion for determining whether the electronic device 400 additionally uses a transmission path to transmit data. The electronic device 400 may update the threshold value. For example, the electronic device 400 may change the threshold value periodically or aperiodically. For example, the electronic device 400 may change the threshold value in consideration of the amount of data to be transmitted. According to an embodiment, the electronic device 400 may update the threshold value based on the uplink split threshold (ul-datasplitthreshold) received from the network (eg, the eNB 445). For example, the electronic device 400 may update the threshold value within a range in which the threshold value does not exceed an uplink split threshold (ul-datasplitthreshold), but is not limited thereto. For example, the electronic device 400 may update the threshold so that the threshold exceeds a value (eg, 1 Mbyte) specified in an uplink split threshold (ul-datasplitthreshold).
