Description

Electronic devices that report communication quality measurement results and their operation methods {ELECTRONIC DEVICE FOR REPORTING RESULT OF MEASURING QUALITY OF COMMUNICATION AND METHOD FOR THE SAME}

Various embodiments of the present invention relate to an electronic device and a method of operating the electronic device, and more particularly, to an electronic device supporting dual connectivity.

As various electronic devices such as smart phones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop personal computers (laptop PCs), and wearable devices are spreading, In addition, various wireless communication technologies are being developed that are used for various electronic devices to perform communication.

Efforts are being made to develop an improved 5G communication system or a pre-5G communication system in order to meet the increasing demand for wireless data traffic after the commercialization of 4G communication systems. For this reason, the 5G communication system or the pre-5G communication system is called a communication system after a 4G network (Beyond 4G Network) or a system after an LTE system (Post LTE). In order to achieve a high data rate, in addition to the band below 6G, the 5G communication system is also considering implementation in the ultra high frequency (mmWave) band (eg, such as the 60 Giga (60 GHz) band). In 5G communication systems, beamforming, massive array multiple input/output (MIMO), full dimensional multiple input/output (FD-MIMO), array antenna, analog beam-forming, And large scale antenna technologies are being discussed.

For example, the frequency band supported by 5G can also use a higher frequency band than the conventional communication method. When the electronic device uses a frequency band communication method supported by 5G, power consumption may be greater than that of using a conventional communication method.

When the power consumption increases, the temperature of the electronic device may increase. When the temperature of the electronic device increases, power consumed by the electronic device further increases, and the actual usable time of the electronic device may decrease. Furthermore, when the temperature of the electronic device increases, various components included in the electronic device may be damaged, and a threshold voltage for operating the various components may increase, resulting in a phenomenon that requires higher power consumption.

In the case of a communication method that supports both 4G communication and 5G communication, a base station supporting 4G communication can be used as a master node, and a base station supporting 5G communication can be used as a secondary node.

Electronic devices supporting both 4G communication and 5G communication switch the communication processor supporting 5G communication to an idle state when no data transmission or reception operation using 5G communication occurs, thereby reducing power consumption. Can be reduced. In order to switch the communication processor supporting 5G communication to the idle state, it is possible to disconnect the 5G communication. In order to disconnect the 5G communication, the master node may transmit a signal instructing to disconnect the 5G communication. The master node may simultaneously transmit a signal instructing to measure the quality of 5G communication together with a signal instructing the release. According to an embodiment, when both signals are received, the electronic device may transmit a 5G communication quality measurement result to the master node while disconnecting the 5G communication. After receiving the quality result of the 5G communication, the master node performs the connection of the 5G communication again, so that the disconnection and reconnection of the 5G communication may be repeated. The electronic device may increase power consumption as 5G communication is repeatedly connected and disconnected.
