The second communication processor 214 may establish a communication channel corresponding to a designated band (e.g., approximately 6 GHz to 60 GHz) among bands to be used for wireless communication with the second network 294, and may support 5G network communication via the established channel According to various embodiments, the second network 294 may be a 5G network defined in 3GPP. Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated band (e.g., lower than 6 GHz) among bands to be used for wireless communication with the second network 294, and may support 5G network communication via the established channel According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to variou embodiments, the first communication processor 212 or the second communication processor 214 may be implemented in a single chip or a single package, together with the processor 120, the sub-processor 123, or the communication module 190.
[0046] In the case of transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal in a range of approximately 700 MHz to 3 GHz used for the first network 292 (e.g., a legacy network). In the case of reception, an RF signal is obtained from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242), and may be preprocessed via an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal to a baseband signal so that the base band signal is processed by the first communication processor 212.
[0047] In the case of transmission, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., lower than 6 GHz) used for the second network 294 (e.g., 5G network). In the case of reception, a 5G Sub6 RF signal is obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244), and may preprocessed by an RFFE (e.g., the second RFFE, 234). The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the baseband signal is processed by a corresponding communication processor from among the first communication processor 212 or the second communication processor 214.
[0048] The third RFIC 226 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, a 5G Above6 RF signal) of a 5G Above6 band (e.g., approximately 6 GHz to 60 GHz) to be used for the second network 294 (e.g., 5G network). In the case of reception, a 5G Above6 RF signal is obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248), and may be preprocessed by the third RFFE 236. The third RFIC 226 may convert the preprocessed 5G Above6 RF signal to a baseband signal so that the base band signal is processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be implemented as a part of the third RFIC 226.
[0049] According to an embodiment, the electronic device 101 may include the fourth RFIC 228, separately from or as a part of the third RFIC 226. In this instance, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, an IF signal) in an intermediate frequency band (e.g., approximately 9 GHz to 11 GHz), and may transfer the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal to a 5G Above6 RF signal. In the case of reception, a 5G Above6 RF signal is received from the second network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248), and may be converted into an IF signal by the third RFFE 226. The fourth RFIC 228 may convert the IF signal to a baseband signal so that the base band signal is processed by the second communication processor 214.
[0050] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as a single chip or at least a part of a single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as a single chip or at least a part of a single package. According to an embodiment, at least one antenna module of the first antenna module 242 or the second antenna module 244 may be omitted, or may be combined with another antenna module so as to process RF signals in a plurality of bands.
[0051] According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed in the same substrate, and may form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed in a first substrate (e.g., main PCB). In this instance, the third RFIC 226 is disposed in a part (e.g., a lower part) of the second substrate (e.g., a sub PCB) separate from the first substrate and the antenna 248 is disposed on another part (e.g., an upper part), so that the third antenna module 246 is formed. By disposing the third RFIC 226 and the antenna 248 in the same substrate, the length of a transmission line therebetween may be reduced. For example, this may reduce a loss (e.g., attenuation) of a signal in a high-frequency band (e.g., approximate 6 GHz to 60 GHz) used for 5G network communication, the loss being caused by a transmission line. Accordingly, the electronic device 101 may improve the quality or speed of communication with the second network 294 (e.g., 5G network).
[0052] According to an embodiment, the antenna 248 may be implemented as an antenna array including a plurality of antenna elements which may be used for beamforming. In this instance, the third RFIC 226 may be, for example, a part of the third RFFE 236, and may include a plurality of phase shifters 238 corresponding to a plurality of antenna elements. In the case of transmission, each of the plurality of phase shifters 238 may shift the phase of a SG Above6RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a SG network) via a corresponding antenna element. In the case of reception, each of the plurality of phase shifters 238 may shift the phase of the SG Above6 RF signal received from the outside via a corresponding antenna element into the same or substantially the same phase. This may enable transmission or reception via beamforming between the electronic device 101 and the outside.
[0053] The second network 294 (e.g., SG network) may operate independently (e.g., Stand-Along (SA)) from the first network 292 (e.g., a legacy network), or may operate by being connected thereto (e.g., Non-Stand Alone (NSA)). For example, in the SG network, only an access network (e.g., SG radio access network (RAN) or next generation RAN (NG RAN)) may exist, and a core network (e.g., next generation core (NGC)) may not exist. In this instance, the electronic device 101 may access an access network of the 5G network, and may access an external network (e.g., the Internet) under the control of the core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., New Radio (NR) protocol information) for communication with the 5G network may be stored in the memory 230, and may be accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0068] According to various embodiments, the electronic device 101 may transmit or receive a control message and user data via cellular communication. The control message, for example, may include a message related to at least one of security control, bearer setup, authentication, registration, or mobility management in association with the electronic device 101. The user data, for example, may be user data, excluding a control message transmitted or received between the electronic device 101 and the core network 430.
[0069] Referring to
[0070] According to various embodiments, in an MR-DC environment, at least one of a plurality of base stations 410 and 420 may operate as the master node 410, and the other may operate as the secondary node 420. The master node 410 may be connected to the core network 430 and may transmit or receive a control message. The master node 410 and the secondary node 420 are connected via a network interface and may perform transmission or reception of a message related to radio resource management (e.g., a communication channel) therebetween.
[0071] According to various embodiments, the master node 410 and the secondary node 420 may be entities that perform communication using signals in different frequency bands. According to an embodiment, the master node 410 may be a base station that transmits or receives a signal of a first frequency band. The secondary node 420 may be a base station that transmits or receives a signal of a second frequency band.
[0072] According to various embodiments of the disclosure, the first frequency band may be a frequency band lower than the second frequency band. For example, the first frequency band may be a signal of a 6 GHz or less (e.g., frequency range 1 (FR1)) and the second frequency band may be a signal of 6 GHz or more (e.g., FR2). A signal of the second frequency band may have higher straightness than that of a signal of the first frequency band, and thus path loss and loss caused by an external object may be high. Therefore, cellular communication using the second frequency band may require power higher than cellular communication using the first frequency band. The second frequency band is a frequency band that is relatively higher than the first frequency band. The cellular communication that uses the second frequency band may use a bandwidth wider than that of cellular communication that uses the first frequency band, and thus high-speed data transmission may be enabled.
[0073] According to various embodiments of the disclosure, the core network 430 (or a cellular communication network) may perform handover of the electronic device 101 based on an environment (e.g., a network resource) of a cellular communication network. For example, the core network 430 may enable the electronic device 101 to be connected to the secondary node 420 in the state in which the electronic device 101 is connected to the master node 410. However, although it is appropriate that the electronic device 101 is connected to the master node 410, as opposed to the secondary node 420, according to the state of the electronic device 101, the core network 430 may perform handover of the electronic device 101, and thus the amount of power consumed by the electronic device 101 may be increased.
[0074] According to various embodiments of the disclosure, the core network 430 (or a cellular communication network) may perform dual connectivity of the electronic device 101 based on an environment (e.g., a network resource) of a cellular communication network. For example, the core network 430 may enable the electronic device 101 to be additionally connected to the secondary node 420 in the state in which the electronic device 101 is connected to the master node 410. However, although it is appropriate that the electronic device 101 is connected to only the master node 410 according to the state of the electronic device 101, the core network 430 may additionally connect the electronic device 101 to the secondary node 420, and thus the amount of power consumed by the electronic device 101 may be increased.
[0075] Hereinafter, a detailed embodiment that performs handover in consideration of the state of the electronic device 101 will be described in detail.

[0245] It should be appreciated that various embodiments of the present disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular example embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and do not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
[0246] As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, or any combination thereof, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
[0247] Various embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a compiler or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium, where the term “non-transitory” simply refers to the storage medium being a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
[0248] According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
