Description

Technical Field

[0001] The present disclosure relates to an electronic device for performing antenna tuning and a method thereof. Background Art

[0002] Due to the development of wireless communication systems, voice call services can be provided through a network. For example, Voice over Long-Term Evolution (VoLTE) can provide voice call services through a high-speed data communication packet network LTE, just like through a traditional circuit network. Compared with traditional circuit calls, VoLTE can provide a faster connection speed and significantly improved call quality, while ensuring the quality of communication operators in the same way as mobile Voice over Internet Protocol (mVoIP) calls.

[0003] With the recent development of mobile communication technologies leading to the widespread use of mobile devices equipped with various functions, efforts are being made to develop a fifth-generation (5G) communication system to meet the growing demand for wireless data services. To achieve high data rates, in addition to the high frequency bands used in third-generation (3G) and LTE, the implementation of 5G communication systems in the super high frequency band is also considered.

[0004] For example, beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technologies for 5G communication systems are being discussed to mitigate the path loss of radio waves in the millimeter wave band and increase the propagation distance of radio waves.

[0005] To send a signal to a communication network (e.g., a base station (BS)), an electronic device may send data generated by its internal processor or communication processor to the outside through at least one antenna after signal processing of the data by a radio frequency integrated circuit (RFIC) and a radio frequency front-end (RFFE) circuit.

[0006] As a way to implement 5G communication, stand-alone (SA) and non-stand-alone (NSA) schemes are considered. The NSA scheme may include E-UTRA NR dual connectivity (EN-DC), in which a new radio (NR) system is used in combination with a traditional LTE system. In the NSA scheme, a user equipment (UE) may use a next-generation node B (gNB) of the NR system and an evolved node B (eNB) of the LTE system. Technologies that enable a UE to use heterogeneous communication systems may be referred to as dual connectivity.

[0007] Dual connectivity was first proposed by the 3rd Generation Partnership Project (3GPP) Release-12. The use of the 3.5 GHz band as a small cell in addition to the LTE system was initially proposed. The use of dual connectivity proposed by 3GPP Release 12 is being discussed to implement EN-DC, such that communication is performed using the LTE network via the master node (MN), and communication is performed using the NR network via the secondary node (SN).

[0008] The UE may receive a message (e.g., a Radio Resource Control (RRC) connection reconfiguration message) from the MN for instructing the UE to report at least one parameter corresponding to a neighbor cell. For example, the at least one parameter may be a Reference Signal Received Power (RSRP) or a Signal-to-Interference-and-Noise Ratio (SINR). The at least one parameter corresponding to the neighbor cell is not limited to the above examples. The UE may measure at least one parameter of the signal from the BS in the neighboring cell and report the parameter to the MN. The MN may determine to add a specific BS as the SN and command the UE to add a Secondary Cell Group (SCG). The UE may send and receive data to and from the network based on communication with the two networks. The UE supporting EN-DC may support both LTE and 5G communication. For example, the UE may send and receive control plane data and user plane data via LTE communication, and send and receive user plane data via 5G communication.

[0009] Dynamic Spectrum Sharing (DSS) is a technology that allows both LTE and NR to be deployed in the same frequency band. Based on DSS, the LTE-supporting UE and the NR-supporting UE may communicate with their respective networks in the same frequency band or via the same channel. Summary of the Invention

Based on a change in the electric field, switching from the first antenna tuning mode to the second antenna tuning mode is associated with a decrease in a parameter related to the antenna sensitivity of the second transmission channel connection based on the second RAT.

The communication module 190 may include one or more communication processors capable of operating independently of the processor 120 (e.g., an application processor (AP)), and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). Each of these communication modules may communicate with an external electronic device via a first network 198 (e.g., a short-range communication network, such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network, such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or these various types of communication modules may be implemented as multiple separate components (e.g., multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an international mobile subscriber identity (IMSI)) stored in the user identification module 196.

The one or more external electronic devices that receive the request may perform the requested at least part of the function or service, or perform additional functions or additional services related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least part of a reply to the request with or without further processing of the result. To this end, for example, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology, or client-server computing technology may be used. The electronic device 101 may use, for example, distributed computing or mobile edge computing to provide an ultra-low latency service. In another embodiment, the external electronic device 104 may include an Internet of Things (IoT) device. The server 108 may be an intelligent server using machine learning and / or neural networks. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

Refer to Figure 2a, the electronic device 101 may include a first communication processor (e.g., including processing circuitry) 212, a second communication processor (e.g., including processing circuitry) 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, a third antenna module 246, and an antenna 248. The electronic device 101 may further include a processor 120 and a memory 130. The memory 130 may store instructions. When executed by at least one processor (e.g., an application processor and / or a communication processor), the instructions may cause the electronic device 101 to perform at least one operation. The second network 199 may include a first cellular network 292 and a second cellular network 294. According to an embodiment, the electronic device 101 may further include Figure 1 at least one component of the components shown in, and the second network 199 may further include at least one other network. According to an embodiment, the first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may form at least a part of the wireless communication module 192. According to an embodiment, the fourth RFIC 228 may be omitted or included as part of the third RFIC 226.

[0062] The first communication processor 212 may support establishing a communication channel in a frequency band to be used for wireless communication with the first cellular network 292 and support legacy network communication through the established communication channel. According to an embodiment, the first cellular network may be a legacy network including a second generation (2G), third generation (3G), fourth generation (4G), or long term evolution (LTE) network. The second communication processor 214 may support establishing a communication channel corresponding to a designated frequency band (e.g., from about 6 GHz to about 60 GHz) of a frequency band to be used for wireless communication with the second cellular network 294 and support 5G network communication through the established communication channel. According to an embodiment, the second cellular network 294 may be a 5G network defined by the 3rd Generation Partnership Project (3GPP). Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may support establishing a communication channel corresponding to another designated frequency band (e.g., below about 6 GHz) of a frequency band to be used for wireless communication with the second cellular network 294 and support 5G network communication through the established communication channel.

[0063] The first communication processor 212 can send data to and receive data from the second communication processor 214. For example, data classified to be sent through the second cellular network 294 can be changed to data classified to be sent through the first cellular network 292. In this case, the first communication processor 212 can receive the transmission data from the second communication processor 214. For example, the first communication processor 212 can send data to and receive data from the second communication processor 214 through the inter-processor interface 213. The inter-processor interface 213 can be implemented as, for example but not limited to, a Universal Asynchronous Receiver / Transmitter (UART) (e.g., High-Speed UART (HS-UART)) or a Peripheral Component Interconnect Express (PCIe) interface. Alternatively, the first communication processor 212 and the second communication processor 214 can exchange control information and packet data information using, for example, a shared memory. The first communication processor 212 can send to and receive from the second communication processor 214 various information such as sensing information, information about output strength, and Resource Block (RB) allocation information.

[0064] According to an embodiment, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 can send data to and receive data from the second communication processor 214 through the processor 120 (e.g., an application processor). For example, the first communication processor 212 and the second communication processor 214 can communicate with the processor 120 (e.g., an application processor) through an HS-UART interface or a PCIe interface. However, the type of the interface is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 can use a shared memory to exchange control information and packet data information with the processor 120 (e.g., an application processor).

[0065] According to an embodiment, the first communication processor 212 and the second communication processor 214 can be implemented on a single chip or within a single package. According to an embodiment, the first communication processor 212 or the second communication processor 214 can be formed on a single chip or within a single package together with the processor 120, the auxiliary processor 123, or the communication module 190. For example, as Figure 2b shown, the communication processor 260 can support all functions for communicating with both the first cellular network 292 and the second cellular network 294.

[0066] During transmission, the first RFIC 222 may convert the baseband signal generated by the first communication processor 212 into an RF signal in the range of approximately 700 MHz to approximately 3 GHz for use in the first cellular network 292 (e.g., a legacy network). During reception, the RF signal may be obtained from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242) and preprocessed by the RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal into a baseband signal for processing in the first communication processor 212.

[0067] During transmission, the second RFIC 224 may convert the baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal in the Sub6 band (e.g., below approximately 6 GHz) for use in the second cellular network 294 (e.g., a 5G network) (hereinafter referred to as a 5G Sub6 RF signal). During reception, the 5G Sub6 RF signal may be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244) and preprocessed by the RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal into a baseband signal for processing in the corresponding one of the first communication processor 212 and the second communication processor 214.

[0068] The third RFIC 226 may convert the baseband signal generated by the second communication processor 214 into an RF signal in the 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz) for use in the second cellular network 294 (e.g., a 5G network). During reception, the 5G Above6 RF signal may be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and preprocessed by the third RFFE 236. The third RFIC 226 may convert the preprocessed 5G Above6 RF signal into a baseband signal for processing in the second communication processor 214. In an embodiment, the third RFFE 236 may be formed as part of the third RFIC 226.

[0069] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 that is separate from or at least part of the third RFIC 226. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an RF signal in an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz) (hereinafter referred to as an intermediate frequency (IF) signal), and then send the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. During reception, the 5G Above6 RF signal may be received from a second cellular network 294 (e.g., a 5G network) through an antenna such as antenna 248 and converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal for processing in the second communication processor 214.

[0070] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single chip or a single package. According to an embodiment, when Figure 2a or Figure 2b the first RFIC 222 and the second RFIC 224 in

[0071] According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate to form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 may be disposed in a partial area (e.g., on the bottom surface) of a second substrate (e.g., a sub-PCB) separated from the first substrate, and the antenna 248 may be disposed on another partial area of the second substrate (e.g., on the top surface), thereby forming the third antenna module 246. It is possible to reduce the length of the transmission line between the third RFIC 226 and the antenna 248 by placing the third RFIC 226 and the antenna 248 on the same substrate. This may reduce, for example, the loss (e.g., attenuation) of signals in a high frequency band (e.g., from about 6 GHz to about 60 GHz) for 5G network communication caused by the transmission line. Accordingly, the electronic device 101 may improve the quality or speed of communication with the second network 294 (e.g., a 5G network).

[0072] According to an embodiment, the antenna 248 may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC 226 may include, for example, a plurality of phase shifters 238 corresponding to the plurality of antenna elements as part of the third RFFE 236. During transmission, each of the plurality of phase shifters 238 may change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (e.g., transmitted to a BS in a 5G network) through a corresponding antenna element. During reception, each of the plurality of phase shifters 238 may convert the phase of a 5G Above6 RF signal received from the outside through a corresponding antenna element into the same or substantially the same phase. This enables transmission or reception by beamforming between the electronic device 101 and the outside.

[0073] The second cellular network 294 (e.g., a 5G network) may operate independently of the first cellular network 292 (e.g., a legacy network) (e.g., SA) or may operate in combination with the first cellular network 292 (e.g., NSA). For example, a 5G network may have only an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NG RAN)) without a core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101 may access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., an evolved packet core (EPC)). Protocol information for communicating with the legacy network (e.g., LTE protocol information) or protocol information for communicating with the 5G network (e.g., NR protocol information) may be stored in the memory 230 and accessed by other components (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0074] Figure 3a 、 Figure 3b and Figure 3c is a diagram illustrating a wireless communication system for providing a network for traditional communication and / or 5G communication according to an embodiment. Figure 3a 、 Figure 3b and Figure 3c , the network environments 300a, 300b, and 300c may include at least one of a legacy network or a 5G network. The legacy network may include, for example, a 3GPP 4G or LTE BS 340 (e.g., an evolved Node B (eNB or eNode B)) that supports wireless access for the electronic device 101 and an EPC 342 that manages 4G communications. The 5G network may include, for example, an NR BS 350 (e.g., a next-generation Node B (gNB or gNodeB)) that supports wireless access for the electronic device 101 and a 5G core (5GC) 352 that manages 5G communications for the electronic device 101.

[0075] Depending on the embodiment, the electronic device 101 may transmit and receive control messages and user data via conventional communication and / or 5G communication. The control message may include, for example, a message related to at least one of security control, bearer establishment, authentication, registration, or mobility management of the electronic device 101. The user data may refer to, for example, user data other than the control message transmitted or received between the electronic device 101 and the core network 330 (e.g., the EPC 342).

[0076] refer to Figure 3a , the electronic device 101 according to an embodiment can use at least a part of the traditional network (e.g., LTEBS 340 and EPC 342) to send at least one of control messages or user data to at least a part of the 5G network (e.g., NR BS 350 and 5GC 352) and receive at least one of control messages or user data from at least a part of the 5G network (e.g., NR BS 350 and 5GC 352).

[0077] According to an embodiment, the network environment 300a may include a network environment that provides wireless communication dual connectivity (DC) to the LTE BS 340 and the NR BS 350, and sends and receives control messages to and from the electronic device 101 through the core network 230, which is one of the EPC 342 and the 5GC 352.

[0078] According to an embodiment, in a DC environment, one of the LTE BS 340 and the NR BS 350 may operate as the MN 310, and the other BS may operate as the SN 320. The MN 310 may be connected to the core network 230 and send and receive control messages. The MN 310 and the SN 320 may be connected to each other through a network interface and send and receive messages related to the management of radio resources (e.g., communication channels) to and from each other.

[0079] According to an embodiment, the MN 310 may include the LTE BS 340, the SN 320 may include the NR BS 350, and the core network 330 may include the EPC 342. For example, control messages may be sent and received through the LTE BS 340 and the EPC 342, and user data may be sent and received through at least one of the LTE BS 340 or the NR BS 350.

[0080] According to an embodiment, the MN 310 may include the NR BS 350, the SN 320 may include the LTE BS 340, and the core network 330 may include the 5GC 352. For example, control messages may be sent and received through the NR BS 350 and the 5GC 352, and user data may be sent and received through at least one of the LTE BS 340 or the NR BS 350.

[0081] Referring to Figure 3b , according to an embodiment, the 5G network may include the NR BS 350 and the 5GC 352 and independently send control messages and user data to the electronic device 101 and receive control messages and user data from the electronic device 101.

[0082] Referring to Figure 3c , in each of the conventional network and the 5G network according to an embodiment, data transmission and reception may be provided independently. For example, the electronic device 101 and the EPC 342 may send and receive control messages and user data through the LTE BS 340. For example, the electronic device 101 and the 5GC 352 may also send and receive control messages and user data through the NR BS 350.

[0083] According to an embodiment, the electronic device 101 may be registered to at least one of the EPC 342 or the 5GC 352 to send and receive control messages.

[0084] According to an embodiment, the EPC 342 or the 5GC 352 may interoperate to manage the communication of the electronic device 101. For example, information about the movement of the electronic device 101 may be sent and received through an interface between the EPC 342 and the 5GC 352.

[0085] As described above, the dual connection via the LTE BS 340 and the NR BS 350 can be referred to as the E-UTRA New Radio Dual Connection (EN-DC). The dual connection via the NR BS 350 and the LTE BS 340 can be referred to as the New Radio E-UTRA Dual Connection (NE-DC). In addition to EN-DC, multi-radio dual connections can find various applications. For example, both the first network and the second network of the MR DC can be related to LTE communication, where the second network can be a network corresponding to a small cell in a specific frequency. For example, both the first network and the second network of the MR DC can be related to 5G, where the first network can correspond to a frequency band below 6 GHz (e.g., below 6), and the second network can correspond to a frequency band at or above 6 GHz (e.g., above 6). Those skilled in the art will readily understand that, in addition to the above examples, any network structure is applicable to the embodiments of the present disclosure as long as the dual connection is applicable to the network structure.

[0086] Figure 4 FIG. is a diagram showing bearers in a user equipment (UE) according to an embodiment.

[0087] 5G NSA environment (e.g., Figure 3a The bearers available in the network environment 300a) can include a master cell group (MCG) bearer, a secondary cell group (SCG) bearer, and a split bearer. An E-UTRA / NR packet data convergence protocol (PDCP) entity 401 and NR PDCP entities 402 and 403 can be established in the UE 400. In the UE 400, E-UTRA radio link control (RLC) entities 411 and 412 and NR RLC entities 413 and 414 can be established. In the UE 400, E-UTRA media access control (MAC) entity 421 and NR MAC entity 422 can be established. A UE can represent a user equipment capable of communicating with a BS, and can be used interchangeably with Figure 1 the electronic device 101. For example, in an embodiment, when it is said that the UE performs a specific operation, this can mean that, for example, at least one element included in the electronic device 101 performs the specific operation.

[0088] The MCG can correspond to, for example, Figure 3a the MN 310, and the SCG can correspond to, for example, Figure 3a the SN 320. Once the node to communicate with is determined, the UE 400 can establish Figure 4The various entities shown communicate with the determined nodes, such as the BS. The PDCP entities 401, 402, and 403 can receive data (e.g., PDCP service data units (SDUs) corresponding to Internet Protocol (IP) packets) and output transformed data (e.g., PDCP protocol data units (PDUs)) that reflect additional information (e.g., header information). The RLC entities 411, 412, 413, and 414 can receive the transformed data (e.g., PDCP PDUs) output from the PDCP layer entities 401, 402, and 403 and output transformed data (e.g., RLC PDUs) that reflect additional information (e.g., header information). The MAC entities 421 and 422 can receive the transformed data (e.g., RLC PDUs) output from the RLC entities 411, 412, 413, and 414 and output transformed data (e.g., MAC PDUs) that reflect additional information (e.g., header information) to the physical layer (not shown).

[0089] An MCG bearer can be associated with a path (or data) through which data can be sent and received using only the resources or entities corresponding to the MN in a dual connection. An SCG bearer can be associated with a path (or data) through which data can be sent and received using only the resources or entities corresponding to the SN in a dual connection. A split bearer can be associated with a path (or data) through which data can be sent and received using the resources or entities corresponding to the MN and the resources or entities corresponding to the SN in a dual connection. Thus, as Figure 4 shown, a split bearer can be associated with both the E-UTRA RLC entity 412 and the NR RLC entity 413 and both the E-UTRA MAC entity 421 and the NR MAC entity 422 via the NR PDCP entity 402.

[0090] Figure 5 is a diagram showing an uplink path between a UE and a BS according to an embodiment.

[0091] In Figure 5Among them, the UE 510 (e.g., the electronic device 101) according to the embodiment can communicate with the BSs 520a and 520b based on the split bearer. Accordingly, the transmission data (e.g., IP packets) to be sent from the UE 510 to the BSs 520a and 520b can be sent to the second RLC entity 543 and the second MAC entity 545 or sent to the first RLC entity 542 and the first MAC entity 544 through the second PDCP entity 541. For example, the first RLC entity 542 and the first MAC entity 544 can be associated with the first network, and the second RLC entity 543 and the second MAC entity 545 can be associated with the second network. The first BS 520a can establish the first PDCP entity 521a, the first RLC entity 522a, and the first MAC entity 523a. The second BS 520b can establish the second PDCP entity 521b, the second RLC entity 522b, and the second MAC entity 523b. The path associated with the second RLC entity 543 and the second MAC entity 545 of the UE 510 can be the primary path 531, and the path associated with the first RLC entity 542 and the first MAC entity 514 can be the secondary path 532. The first PDCP entity 521a can be implemented in the same way as the second PDCP entity 521b. For example, for the implementation of EN-DC, when the BS 520a is an LTE BS, the first PDCP entity 521a can be established as an NR PDCP entity. In the embodiment, a specific PDCP entity (e.g., an NR PDCP entity) can be located at the BS 520a or the BS 520b. When the split bearer is established, at least one of the first PDCP entity 521a or the second PDCP entity 521b can send data to the core network. In the embodiment, the first PDCP entity 521a or the second PDCP entity 521b may not exist. The BSs 520a and 520b can communicate directly with each other.

[0092] The first network and the second network can be any networks as long as they can perform dual connection. For example, the first network and the second network can correspond to LTE communication and NR communication respectively. For example, both the first network and the second network can be used for LTE communication, where the second network corresponds to a small cell in a specific frequency. For example, both the first network and the second network can be used for 5G, where the first network can correspond to a band below 6 GHz (e.g., below 6), and the second network can correspond to a band of 6 GHz or higher (e.g., above 6).

[0093] The UE 510 according to an embodiment may use at least one of the first network or the second network to transmit transmission data to the BSs 520a and 520b based on a split bearer. The UE 510 according to an embodiment may set the second network associated with the second BS 520b corresponding to the SCG as the primary path 531, and set the first network associated with the first BS 520a corresponding to the MCG as the secondary path 532. For example, the UE 510 may set the second network associated with the SCG as the primary path 531 based on the information indicating the primary path received from the MN. The information indicating the primary path received from the MN may be included in an RRC message (e.g., an RRCReconfiguration message). In an embodiment, the method for the UE to set the primary path is not limited. The primary path may be determined, for example, based on the policy of each communication operator, and the UE 510 may identify the primary path by receiving the information indicating the primary path. In the case where a PDCP entity is associated with more than one RLC entity, the primary path may represent the cell group identifier (ID) and the logical channel ID (LCID) of the primary RLC entity for uplink data transmission. The second PDCP entity 521b may be included in the BS 520a having the primary path. According to an embodiment, the first PDCP entity 521a may be included in the BS 520b having the secondary path.

[0094] Reference will be made below to Figure 6 , Figure 7a and Figure 7b to describe the structure and operation of the electronic device 101 according to an embodiment. Although in each of the drawings of the embodiments described below, one communication processor 260 and one RFIC 610 are shown as being connected to a plurality of RFFEs 631 and 632, the embodiments are not limited thereto. In the following embodiments, for example, a plurality of communication processors 212 and 214 and / or a plurality of RFICs 222, 224, 226, and 228 may be connected to the plurality of RFFEs 631 and 632, as Figure 2a or Figure 2b shown.

[0095] Figure 6 is a block diagram showing an electronic device according to an embodiment of the present disclosure. According to an embodiment, Figure 6 shows an embodiment in which the electronic device 101 includes two antennas 641 and 642. Although Figure 6 the electronic device including two antennas is shown by way of example, according to an embodiment, the electronic device 101 may include three or more antennas. For example, when the electronic device 101 operates in multiple-input multiple-output (MIMO), the electronic device 101 may receive signals transmitted in MIMO from the BS through a plurality of antennas (e.g., two or more antennas).

[0096] Referring to Figure 6 , the electronic device (e.g., Figure 1 electronic device 101) according to an embodiment may include a processor 120 (e.g., including processing circuitry), a communication processor 260 (e.g., including processing circuitry), an RFIC 610, a first RFFE 631, a second RFFE 632, a first antenna 641, a second antenna 642, a first antenna tuning circuit 641a, or a second antenna tuning circuit 642a. In an embodiment, the first RFFE 631 may be disposed in a first region within the housing of the electronic device 101, and the second RFFE 632 may be disposed in another region spaced apart from the first region within the housing of the electronic device 101, which should not be construed as limiting the embodiments.

[0097] According to an embodiment, the RFIC 610 may convert a baseband signal generated by the communication processor 260 into an RF signal used in a communication network during transmission. For example, the RFIC 610 may send an RF signal used in a first communication network (e.g., 5G network) or a second communication network (e.g., LTE network) to the first antenna 641 through the first RFFE 631 and the first antenna tuning circuit 641a. The RFIC 610 may send an RF signal for a first communication network (such as a 5G network) or a second communication network (such as an LTE network) to the second antenna 642 through the second RFFE 632 and the second antenna tuning circuit 642a.

[0098] In an embodiment, the first antenna 641 may be electrically connected to the first antenna tuning circuit 641a, and the second antenna 642 may be electrically connected to the second antenna tuning circuit 642a. In an embodiment, the communication processor 260 may adjust (e.g., tune) the characteristics of signals (e.g., transmit (Tx) signals) transmitted and received signals (e.g., receive (Rx) signals) through each of the connected antennas by adjusting the set values of the first antenna tuning circuit 641a and the second antenna tuning circuit 641a. Specific embodiments of this operation will be described below with reference to Figure 7a and Figure 7b describe specific embodiments of this operation.

[0099] According to an embodiment, the first antenna 641 may be set as the first Rx antenna, and the second antenna 642 may be set as the second Rx antenna. The electronic device 101 may receive a signal transmitted from the BS through the first antenna 641 and / or the second antenna 642 and decode the received signal. For example, the signal received through the first antenna 641 may be transmitted to the communication processor 260 as a first Rx signal through the first antenna tuning circuit 641a, the first RFFE 631, and the RFIC 610. In an example, the signal received through the second antenna 642 may be transmitted to the communication processor 260 as a second Rx signal through the second antenna tuning circuit 642a, the second RFFE 632, and the RFIC 610.

[0100] According to an embodiment, when the electronic device 101 operates in MIMO, the electronic device 101 may be configured by the BS with a rank for MIMO operation. The electronic device 101 may receive a signal transmitted based on MIMO from the BS through the first antenna 641 and the second antenna 642. For ease of description, the signal received through the first antenna 641 may be referred to as the first signal, and the signal received through the second antenna 642 may be referred to as the second signal.

[0101] According to an embodiment, the first RFFE 631 may include at least one duplexer or at least one combiner to process Tx signals and Rx signals together. In one example, the second RFFE 632 may include at least one duplexer or at least one combiner to process Tx signals and Rx signals together.

[0102] In an embodiment, the first antenna 641 may be referred to as the "main antenna". The first antenna 641 may transmit RF signals used in an LTE communication network and / or a 5G communication network. The first antenna 641 may receive RF signals used in an LTE communication network and / or a 5G communication network. In an embodiment, the first antenna 641 may transmit RF signals used in an LTE communication network and RF signals used in a 5G communication network in time division multiplexing (TDM). The transmission scheme of the first antenna 641 is not limited to the foregoing examples.

[0103] In an embodiment, the first antenna 641 may be a Tx antenna or a primary Rx antenna (PRx antenna) and transmit and receive RF signals. When the quality of a voice call service (or quality of service (QoS) or quality of the voice call) is poor, the electronic device 101 that does not include a diversity Tx antenna may mitigate the degradation of the RF signal based on switching the Rx antenna to a diversity Rx antenna (DRx antenna). For example, the electronic device 101 may receive RF signals for LTE communication and / or 5G communication through the second antenna 642. Because the DRx antenna and the Tx antenna are different, the electronic device 101 may not be able to determine whether the transmission channel of the Tx antenna is in good condition based on a parameter associated with the DRx antenna (e.g., RSRP). The electronic device 101 according to an embodiment may maintain the quality of the voice call service based on recognizing that the quality of the voice call service is poor and performing antenna tuning without switching the Rx antenna to the DRx antenna. In the case of EN-DC, for example, based on setting the antenna tuning value to the DC mode, the electronic device 101 may maintain a connection based on two RATs without an NR secondary cell group failure (SCGF) during the execution of an LTE voice (VoLTE) call. In the case of NE-DC, based on setting the antenna tuning value to the DC mode, the electronic device 101 may also maintain a connection based on two RATs without an LTE SCGF during the execution of a VoNR call.

[0104] Figure 7a is a block diagram illustrating an antenna tuning circuit according to an embodiment of the present disclosure. Figure 7b is a diagram illustrating an antenna tuning circuit according to an embodiment of the present disclosure. Refer to Figure 7a , the antenna tuning circuit 640a according to an embodiment (e.g., Figure 6 the first antenna tuning circuit 641a or the second antenna tuning circuit 642a in Figure 1 may include at least one impedance tuning circuit 610 and / or at least one aperture tuning circuit 620. Although the second antenna tuning circuit 642a may be implemented in the same manner as the first antenna tuning circuit 641a, they may also be implemented differently. The impedance tuning circuit 610 according to an embodiment may be configured to perform impedance matching with a network under the control of at least one processor (e.g., Figure 2a the processor 120 of Figure 2b the communication processors 212 and 214 of

[0105] or at least one of the integrated communication processors 260 of Figure 6The impedance tuning circuit 610 may be connected to an antenna (eg, a first RFFE 631 or a second RFFE 632) and connected to a duplexer of the RFFE. Figure 6 The first antenna 641 or the second antenna 642 in the embodiment of the present invention may be connected to a power supply rail connecting the impedance tuning circuit 610 and the antenna, and the first aperture tuning circuit (not shown) and the second aperture tuning circuit (not shown) may be connected to the power supply rail connecting the impedance tuning circuit 610 and the antenna.

[0106] According to an embodiment, the electronic device 101 (e.g., the communication processor 260) may change the setting value of the antenna tuning circuit 640a based on the strength of the received signal (e.g., at least one of RSRP, signal-to-noise ratio (SNR), or SINR) or whether an imbalance occurs. In an embodiment, the electronic device 101 may control the on / off state of the switches included in the antenna tuning circuit 640a (e.g., the impedance tuning circuit 610 and / or the aperture tuning circuit 620) to change as described above in response to the change in the setting value of the antenna tuning circuit 640a.

[0107] According to the embodiment, although Figure 7b 6. In FIG. 6 , one impedance tuning circuit 610 and one aperture tuning circuit 620 are shown connected to one antenna, but the impedance tuning circuit 610 or the aperture tuning circuit 620 may be omitted, or a plurality of impedance tuning circuits 610 or a plurality of aperture tuning circuits 620 may be included for one antenna.

[0108] In an embodiment, electronic device 101 may select antenna tuning values based on the execution of a voice call service to prioritize the quality of the voice call service. Based on the selected antenna tuning values, electronic device 101 may mitigate degradation in the quality of the voice call service. For example, electronic device 101 may determine an antenna tuning mode based on the execution of a VoLTE call, such that the antenna is tuned to the frequency band of the first cell (e.g., the primary cell (PCell)) of the LTE network.

[0109] Figure 8 is a diagram showing the arrangement of antennas in an electronic device according to an embodiment.

[0110] In an embodiment, the electronic device 101 may include a first antenna 811, a second antenna 813, a third antenna 815, and a fourth antenna 817. In an embodiment, Figure 8 Antennas 811, 813, 815, and 817 may be laser direct structuring (LDS) antennas formed as patterns in certain areas within the housing of electronic device 101. Antennas 811, 813, 815, and 817 may also be implemented as metal antennas on the housing, and the specific implementation method is not limited.

[0111] In an embodiment, Figure 8At least one of antennas 811, 813, 815, and 817 may transmit and receive RF signals based on two RATs in DC. For example, the electronic device 101 may transmit and receive RF signals in the LTE band through the first antenna 811 and transmit and receive RF signals in a 5G band that is at least partially the same as the LTE band based on spectrum refarming. The electronic device 101 may use the first antenna 811 as a Tx antenna and a PRx antenna. The first antenna 811 may transmit and receive RF signals corresponding to the B66 band and / or RF signals corresponding to the N5 band. The electronic device 101 may use any of the remaining antennas 813, 815, and 817 as a DRx antenna. For example, the electronic device 101 may receive RF signals corresponding to the B66 band and / or RF signals corresponding to the N5 band through the DRx antenna. In an embodiment, when performing a VoLTE call during the transmission of RF signals in the B66 band and the N5 band based on one antenna, the electronic device 101 may select antenna tuning values that prioritize the B66 band. When adjusting the antenna tuning values to prioritize the B66 band, the transmission and reception performance of RF signals in the N5 band may deteriorate.

[0112] Figure 9a is a block diagram illustrating an electronic device according to an embodiment.

[0113] In an embodiment, the electronic device 101 may include a DC activation identification module 911, a voice call execution identification module 913, an RSRP identification module 915, a tuning mode selection module 917, and an RFFE 920 (e.g., a first RFFE 232, a second RFFE 234, a third RFFE 236, a first RFFE 631, and / or a second RFFE 632). The DC activation identification module 911 may be referred to as a "dual-connection activation checker", and the voice call execution identification module 913 may be referred to as a "voice call service activation checker". The RSRP identification module 915 may be referred to as a "quality of service monitor". The tuning mode selection module 917 may be referred to as a "tuning mode selector". In an embodiment, the modules 911, 913, 915, and 917 included in the communication processor 260 may operate in the physical (PHY) layer (or L1). In addition, each of the above-mentioned modules may include various processing circuits and / or executable program instructions. The DC activation identification module 911 may identify whether a DC-based connection has been established based on identifying the network environment. For example, the DC activation identification module 911 may identify whether it is in an EN-DC scenario or a NE-DC scenario. The voice call execution identification module 913 may be based on a communication module (e.g., Figure 1The communication module 190) to identify whether a voice call has been executed. For example, the voice call execution identification module 913 can identify whether a VoLTE call based on LTE communication has been executed in the EN-DC case. The voice call execution identification module 913 can also identify whether a VoNR call based on 5G communication has been executed in the NE-DC case. The RSRP identification module 915 can identify the electric field of the P cell where the voice call is being executed based on the signal received through the antenna. In one embodiment, the RSRP identification module 915 can identify the filtered RSRP as a measurement within a preset time period. The RSRP identification module 915 can identify the RSRP of the first channel to which LTE communication is connected in the DC state where LTE communication and 5G communication use the same antenna connection. In an embodiment, the RSRP identification module 915 can identify parameters other than RSRP for identifying the electric field. For example, the RSRP identification module 915 can identify the received signal strength indicator (RSSI) or SINR of the first channel to which the first RAT is connected in the DC state. The tuning mode selection module 917 can select an antenna tuning mode from the DC mode or the voice call mode based on at least one of the identified RSRP, SINR, or RSSI. The tuning mode selection module 917 can select an antenna tuning mode based on identifying the electric field of LTE communication, where a VoLTE call is executed in the DC state of connecting LTE communication and 5G communication using the first antenna (e.g., the first antenna 641). For example, the tuning mode selection module 917 can select the DC mode based on identifying that the electric field of LTE communication is good. The tuning mode selection module 917 can select the voice call mode based on identifying that the electric field of LTE communication is poor. The RFFE 920 can identify the tuning code stored in the memory (such as the memory 130) based on the control signal received from the communication processor 260. In an embodiment, the communication processor 260 can operate as an upper layer relative to the RFFE 920. When the tuning mode selection module 917 selects the DC mode, the RFFE 920 can identify the tuning code corresponding to the DC mode 923. The RFFE 920 can set the DC mode 923 based on inputting the tuning code corresponding to the DC mode 923 into the antenna tuning circuit (e.g., the antenna tuning circuit 640a). The RFFE 920 can tune the characteristics of the signal transmitted and / or received through the antenna to maintain the dual-RAT-based connection by controlling the capacitance corresponding to at least one capacitor included in the antenna tuning circuit 640a and / or the on / off state of at least one switch according to the tuning code corresponding to the DC mode 923. When the tuning mode selection module 917 selects the voice call mode, the RFFE 920 can identify the tuning code corresponding to the voice call mode 921.The RFFE 920 may set the voice call mode 921 based on inputting a tuning code corresponding to the voice call mode 921 to the antenna tuning circuit 640a. The RFFE 920 may tune the characteristics of signals transmitted and / or received through the antenna by changing the states of at least one element (e.g., a capacitor and / or a switch) included in the antenna tuning circuit 640a according to the tuning code corresponding to the voice call mode 921 to improve the performance of the RAT associated with the voice call. In an embodiment, the voice call mode 921 and the DC mode 923 shown as being included in the RFFE are for illustrative purposes only, and the codes, values, and / or instructions associated with each mode may be stored in the memory 130. For example, when the quality of the voice call service is poor, the RFFE 920 may input a tuning code that prioritizes the RAT supporting the voice call service to the antenna tuning circuit 640a. The RFFE 920 may input a tuning code that maintains the performance of two DC-based RATs to the antenna tuning circuit 640a based on recognizing that the quality of the voice call service is good. In an embodiment, the modules 911, 913, 915, and 917 implemented (or stored) in the electronic device 101 may be implemented in the form of an application, a program, computer code, instructions, routines, processes, software, firmware, or a combination of at least two of them that can be executed by a processor (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260). For example, when each module is executed, the processor 120 may perform operations corresponding to the respective modules. Therefore, when it is said that "a specific module performs an operation", this may be understood as "when the specific module is executed, the processor 120 performs an operation corresponding to the specific module". In an embodiment, at least some modules may include multiple programs, and the present disclosure is not limited thereto. At least some modules may be implemented in hardware (e.g., a processing circuit (not shown)).

[0114] Figure 9b is a graph showing the antenna efficiency in a strong electric field in an electronic device according to an embodiment.

[0115] Figure 9c is a graph showing the antenna efficiency in a weak electric field in an electronic device according to an embodiment.

[0116] In an embodiment, the electronic device 101 may set the antenna tuning mode to a voice call mode or a DC mode in a DC situation. The electronic device 101 may use a main antenna (e.g., the first antenna 641 and the first antenna 811) to identify whether it is in a DC state where it is connected to a first RAT and a second RAT. The electronic device 101 may also identify whether a voice call has been executed. The electronic device 101 may also identify an electric field condition based on the first RAT and / or the second RAT. For example, the electronic device 101 may identify whether the electric field based on the first RAT is strong or weak. The electronic device 101 may identify whether the electric field based on the second RAT is strong or weak. For example, the electronic device 101 may perform antenna tuning to the voice call mode based on identifying that the intensity of the signal received through the main antenna is less than a threshold value.

[0117] Reference Figure 9b , curves 930a of the overall antenna efficiency when the electronic device 101 operates in the voice call mode and curves 930b of the overall antenna efficiency when the electronic device 101 operates in the DC mode are shown in a strong electric field. The electronic device 101 may perform a voice call based on the first RAT. The difference 931 between the antenna efficiency Ga of the first RAT in the voice call mode and the antenna efficiency Gc of the first RAT in the DC mode may be relatively small. Even when the electronic device 101 is set to the DC mode, it may maintain good channel conditions in the first RAT for performing a voice call. The antenna efficiency Gd of the second RAT in the DC mode may have a value greater than the difference 933 shown in the graph compared to the antenna efficiency Gb of the second RAT in the voice call mode. The electronic device 101 may maintain the reception performance of the secondary cell (S cell) relatively the same through a DRx antenna (e.g., the second antenna 642). The electronic device 101 may transmit signals based on the first RAT and the second RAT using only one antenna (e.g., the first antenna 641). When the electronic device 101 operates in the voice call mode, the transmission performance based on the second RAT may be reduced. The electronic device 101 may stabilize the connection based on the first RAT and the second RAT based on setting the DC mode in which the transmission and reception performance of the second RAT is relatively good.

[0118] Reference Figure 9c , curves 940a of the overall antenna efficiency when the electronic device 101 operates in the voice call mode and curves 940b of the overall antenna efficiency when the electronic device 101 operates in the DC mode are shown in a weak electric field. The electronic device 101 may perform a voice call based on the first RAT. The antenna efficiency G a ' of the first RAT in the voice call mode and the antenna efficiency G cThe difference between them may be relatively large. When the electronic device 101 is set to the DC mode, the antenna efficiency G of the first RAT for performing a voice call c ' may decrease, and the quality of the voice call may deteriorate. The antenna efficiency Gd' of the second RAT in the DC mode may be greater than the antenna efficiency G of the second RAT in the voice call mode by the value of the difference 943 shown in the graph. The electronic device 101 may obtain the transmission and reception performance of the second RAT in the DC mode. The electronic device 101 may set the antenna tuning mode to the voice call mode based on increasing the transmission and reception performance 941 of the first RAT for performing a voice call, so that the quality of the voice call service remains good. b ' by the value of the difference 943 shown in the graph. The electronic device 101 may obtain the transmission and reception performance of the second RAT in the DC mode. The electronic device 101 may set the antenna tuning mode to the voice call mode based on increasing the transmission and reception performance 941 of the first RAT for performing a voice call, so that the quality of the voice call service remains good.

[0119] Figure 10a is a flowchart (legend 1000) showing a method of operating an electronic device according to an embodiment.

[0120] According to an embodiment, in operation 1001, an electronic device 101 (e.g., at least one of a processor 120, a first communication processor 212, a second communication processor 214, and / or an integrated communication processor 260) may establish a first connection based on a first radio access technology (RAT) and establish a second connection based on a second RAT. In an embodiment, the electronic device 101 may establish a first connection based on a first RAT and establish a second connection based on a second RAT in dual connectivity (DC). The DC may include Evolved-Network Dual Connectivity (EN-DC), Next Generation Radio Access Network E-UTRA-NR Dual Connectivity (NGEN-DC), Non-Standalone Evolved-Network Dual Connectivity (NE-DC), or NR-NR Dual Connectivity (NR-DC). Herein, the first RAT and the second RAT are not necessarily different. For example, the first RAT and the second RAT may be the same RAT, such as in NR-DC, and the RAT may be referred to as a node. For example, after establishing a first connection based on a master cell group (MCG) RAT, the electronic device 101 may receive an RRC reconfiguration message from a network corresponding to the MCG RAT. The electronic device 101 may perform measurements based on an inter-RAT measurement object (MO) included in the RRC reconfiguration message. When a measurement result satisfies a reporting condition (e.g., a B1 event), the electronic device 101 may perform a measurement report. The MCG network may determine whether to add a secondary cell group (SCG) based on the measurement report. When it is determined to add the SCG, the MCG network may send an RRC reconfiguration message for adding SCG configuration to the electronic device 101. The electronic device 101 may perform a random access (RA) procedure with the SCG network based on information included in the RRC reconfiguration message, thereby establishing a second connection with the SCG network. In an embodiment, the electronic device 101 (e.g., a DC activation identification module 910) may identify whether the electronic device 101 is attached to a DC network. Based on the identification that the electronic device 101 is attached to the DC network, the electronic device 101 may determine a tuning code to be input to an antenna tuning circuit (e.g., an antenna tuning circuit 640a) to tune the antenna to the first RAT and the second RAT. The antenna tuning value that gives priority to DC may be referred to as a "DC mode".

[0121] In an embodiment, the electronic device 101 may identify whether to perform a voice call based on a first RAT in operation 1003. The electronic device 101 (e.g., a voice call execution identification module 920) may identify whether to perform a voice call and identify a network associated with the voice call. In an embodiment, the first RAT may be associated with Long-Term Evolution (LTE), and the second RAT may be associated with New Radio (NR). The voice call may be based on Voice over LTE (VoLTE). For example, the electronic device 101 may identify whether a VoLTE call is performed in an EN-DC scenario. In an embodiment, the first RAT may be associated with NR, and the second RAT may be associated with LTE. The voice call may be based on Voice over NR (VoNR). For example, the electronic device 101 may identify whether a VoNR call is performed in a NE-DC scenario.

[0122] In an embodiment, when it is recognized that a voice call is being performed, the electronic device 101 may identify at least one parameter associated with a main antenna (e.g., Figure 6 the first antenna 641) in operation 1005. In an embodiment, the electronic device 101 may identify the strength of a signal received through the PRx antenna. For example, the electronic device 101 may identify the RSRP or SINR value of the antenna. The electronic device 101 may identify the RSRP value or SINR value of the LTE P cell based on recognizing that a VoLTE call is being performed in an EN-DC scenario. In an embodiment, the electronic device 101 may start a Real-Time Transport Protocol (RTP) timer and also identify whether the timer has expired.

[0123] In an embodiment, in operation 1007, the electronic device 101 may identify whether the at least one identified parameter satisfies a condition associated with the quality of the voice call. In an embodiment, the condition associated with the quality of the voice call may be that the RSRP value is less than a threshold. For example, the threshold may be approximately -106 dBm, and the specific value of the threshold is not limited. Based on recognizing that the RSRP value of the antenna is less than -106 dBm, the electronic device 101 may identify that the condition associated with the quality of the voice call is satisfied. Based on recognizing that the condition associated with the quality of the voice call is satisfied, the electronic device 101 may identify that the quality of the voice call is poor. In an embodiment, the electronic device 101 may also identify that the quality of the voice call is poor based on recognizing that the RTP timer has expired.

[0124] In an embodiment, when at least one parameter satisfies a condition associated with the quality of the voice call (operation 1007 is "Yes"), the electronic device 101 may control the RF circuit to use a second antenna tuning mode in operation 1009. For example, the electronic device 101 may control the RF circuit to use a voice call mode. In an embodiment, the voice call mode may be an antenna tuning mode that prioritizes voice calls. In an embodiment, the RF circuit may include at least one of an RFIC (e.g., RFIC 610), an RFFE (e.g., the first RFFE 631), an antenna tuning circuit (e.g., the first antenna tuning circuit 641a), an antenna tuning circuit (e.g., the first antenna tuning circuit 641a), or an antenna (e.g., the first antenna 641). The electronic device 101 may determine the tuning value of the Tx antenna to prioritize the voice call based on recognizing that the voice call has poor quality. The electronic device 101 may adjust the setting value of the antenna tuning circuit (e.g., the first antenna tuning circuit 641a and / or the antenna tuning circuit 640a) to prioritize the quality of the voice call service.

[0125] In an embodiment, when at least one parameter does not meet the condition associated with the quality of a voice call (No in operation 1007), the electronic device 101 may control the RF circuit to use the first antenna tuning mode in operation 1011. For example, the electronic device 101 may control the RF circuit to use the DC dual-connection mode. In an embodiment, the DC mode may be an antenna tuning mode for maintaining a first connection based on a first RAT and a second connection based on a second RAT. The electronic device 101 may maintain connections based on two RATs without SCGF by inputting a tuning code corresponding to the DC mode to the antenna tuning circuit 640a while considering the quality of DC-based communication. In an embodiment, in the case of EN-DC, the electronic device 101 may transmit RF signals in an LTE band (e.g., B66 band) and RF signals in a 5G band (e.g., n5 band) through a primary antenna (e.g., the first antenna 641 and / or the first antenna 811). When the electronic device 101 tunes the antenna to the LTE band based on the recognition that a VoLTE call is being performed, the transmission performance of RF signals in the 5G band may deteriorate. As the number of 5G spectrum refarming bands supported by the primary antenna increases, the deterioration of the transmission performance of RF signals in the 5G band may occur in more DC combinations. The electronic device 101 may identify an electric field to prevent and / or reduce the deterioration of the signal transmission performance of the S cell caused by tuning the antenna to the P cell. For example, the electronic device 101 may identify the RSRP value of the primary antenna. Based on the recognition that the RSRP value of the primary antenna is equal to or greater than a threshold, the electronic device 101 may adjust the antenna tuning value to perform reliable communication in a DC environment. Based on setting the antenna tuning value to the DC mode, the electronic device 101 may maintain connections based on two RATs without SCGF.

[0126] Figure 10b is a flowchart (legend 1020) illustrating a method of operating an electronic device according to an embodiment.

[0127] According to an embodiment, in operation 1021, an electronic device 101 (e.g., at least one of a processor 120, a first communication processor 212, a second communication processor 214, and / or an integrated communication processor 260) may establish a first transmission channel connection based on a first RAT and a second transmission channel connection based on a second RAT using one of a plurality of antennas 197, 242, 244, 246, 248, 641, 642, 811, 813, 815, and 817. For example, the electronic device 101 may operate in a DC state based on establishing the first transmission channel connection and the second transmission channel connection using a first antenna 641. In an embodiment, the first antenna 641 may be an antenna configured to transmit and receive RF signals in a band corresponding to the first RAT and transmit and receive RF signals in a band corresponding to the second RAT. In an embodiment, the first RAT may be a RAT associated with a voice call. In an embodiment, the first RAT and the second RAT may be different. At least a part of a band corresponding to the second RAT may be the same as a band corresponding to the first RAT. For example, a band corresponding to the second RAT may be referred to as a "spectrum refarming band".

[0128] In an embodiment, the electronic device 101 may identify in operation 1023 whether a voice call based on the first RAT has been executed. For example, when the electronic device 101 operates in an EN-DC state, the first RAT may be associated with LTE, the second RAT may be associated with NR, and the voice call may be based on VoLTE. When the electronic device 101 operates in a NE-DC state, the first RAT may be associated with NR, the second RAT may be associated with LTE, and the voice call may be based on VoNR. In an embodiment, the electronic device 101 may set an antenna tuning mode to a DC mode based on identifying that the voice call has not been executed. For example, the electronic device 101 may control a state of at least one element (e.g., a capacitor and / or a switch) included in an antenna tuning circuit (e.g., an antenna tuning circuit 640a) based on identifying that a tuning code corresponds to a DC mode stored in a memory (e.g., a memory 130).

[0129] In an embodiment, in operation 1025, the electronic device 101 may identify whether an electric field based on the first RAT is equal to or greater than a first value during execution of a voice call. In an embodiment, the electronic device 101 may identify the electric field based on the first RAT by identifying an RSSI corresponding to the first antenna 641 during execution of the voice call. The first value may be a threshold for identifying whether the electric field based on the first RAT is a strong electric field or a weak electric field. According to an embodiment of the present disclosure, the threshold may be changed.

[0130] In an embodiment, when the electric field based on the first RAT is equal to or greater than a first value, in operation 1027, the electronic device 101 may operate in a first antenna tuning mode. The electronic device 101 may set the first antenna 641 to be tuned to the first RAT and the second RAT based on identifying that the electric field of the RAT performing the voice call is strong. For example, the electronic device 101 may control the state of at least one element included in the antenna tuning circuit 640a based on inputting a tuning code corresponding to the DC mode into the antenna tuning circuit 640a. Based on setting the antenna tuning mode to the DC mode, the electronic device 101 may stably maintain the first transmission channel connection and the second transmission channel connection.

[0131] In an embodiment, when the electric field based on the first RAT is less than the first value, in operation 1029, the electronic device 101 may operate in a second antenna tuning mode. The electronic device 101 may set the first antenna 641 to be tuned to the first RAT based on identifying that the electric field of the RAT performing the voice call is weak. For example, the electronic device 101 may control the state of at least one element included in the antenna tuning circuit 640a based on inputting a tuning code corresponding to the voice call mode into the antenna tuning circuit 640a. Based on setting the antenna tuning mode to the voice call mode, the electronic device 101 may maintain the first transmission channel connection.

[0132] In an embodiment, the electronic device 101 may identify the strength of a signal received through the first antenna 641 based on the first RAT during a voice call. The electronic device 101 may identify that the strength of the received signal is less than a threshold based on monitoring the state of the reception channel based on the first RAT. For example, the electronic device 101 may switch from the first antenna tuning mode to the second antenna tuning mode to prioritize voice call quality based on identifying that the filtered RSRP has dropped below the threshold. In the case of a weak electric field, the electronic device 101 may maintain the first transmission channel connection based on the first RAT performing the voice call by switching the antenna tuning mode from the DC mode to the voice call mode. In an embodiment, when switching the first antenna tuning mode to the second antenna tuning mode according to a change in the electric field, a parameter associated with the antenna sensitivity of the second transmission channel connection based on the second RAT may decrease. For example, the electronic device 101 may identify a parameter associated with the antenna sensitivity of the second transmission channel connection based on identifying the RSRP or SINR of a signal received through the first antenna 641 based on the second RAT. When the DC mode is switched to the voice call mode, the RSRP or SINR based on the second RAT may decrease based on the first antenna 641 being tuned to the first RAT associated with the voice call.

[0133] In an embodiment, the electronic device 101 may identify whether a voice call has been terminated. Based on the identification that the voice call has been terminated, the electronic device 101 may switch from a second antenna tuning mode to a first antenna tuning mode.

[0134] Figure 11 is a flowchart (legend 1100) showing a method of operating an electronic device according to an embodiment.

[0135] According to an embodiment, in operation 1101, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, and / or the integrated communication processor 260) may establish a first connection based on a first RAT and establish a second connection based on a second RAT. The establishment of the first connection based on the first RAT and the second connection based on the second RAT, such as the establishment of a connection based on DC, has been described in detail above and will not be repeated here.

[0136] In an embodiment, in operation 1103, the electronic device 101 may identify the strength of a signal received through a main antenna (e.g., the first antenna 641 or the first antenna 811) based on an identified voice call based on the first RAT. The electronic device 101 may identify the strength of a signal received through the main antenna based on an RSRP or SINR value. In an embodiment, when the electronic device 101 maintains connections based on different first and second RATs, the main antenna may transmit and receive RF signals in a band corresponding to the first RAT and RF signals in a band corresponding to the second RAT. In an embodiment, the band corresponding to the second RAT may be a spectrum refarming band for the band corresponding to the first RAT. For example, at least a part of the band corresponding to the second RAT may be the same as the band corresponding to the first RAT.

[0137] In an embodiment, in operation 1105, the electronic device 101 may identify whether the strength of the received signal is less than a threshold. In an embodiment, the electronic device 101 may estimate the state of the transmission channels of the first RAT and the second RAT by identifying the state of the received channels based on identifying the strength of the received signals of the first RAT and the second RAT. The electronic device 101 may transmit and receive RF signals in an LTE band and RF signals in a 5G band through the same antenna (Tx / PRx). For example, based on identifying that the received channels of LTE network communication and / or 5G network communication are poor, the electronic device 101 may identify that the corresponding transmission channels are also poor. Based on identifying that the received channels of LTE network communication and / or 5G network communication are good, the electronic device 101 may identify that the corresponding transmission channels are also good.

[0138] In an embodiment, when the strength of a received signal is less than a threshold (yes in operation 1105), the electronic device 101 may control the RF circuit in operation 1107 such that the main antenna uses a voice call mode. The electronic device 101 may perform a voice call based on a first RAT in a DC state, where the electronic device 101 uses the same antenna to connect to the first RAT and the second RAT in the DC state. When the received strength of a first channel to which the first RAT is connected during the performance of a voice call based on the first RAT is less than the threshold, the electronic device 101 may improve the transmission / reception performance of the first channel based on controlling the antenna tuning mode to the voice call mode. Based on controlling the antenna tuning mode to the voice call mode, the electronic device 101 may maintain good quality of a voice call service performed on the first channel. The voice call mode may be an antenna tuning mode configured to maximize and / or increase the transmission / reception performance of the first channel. The electronic device 101 may set the antenna tuning value to the voice call mode to maintain good quality of the voice call service.

[0139] In an embodiment, when the strength of a received signal is equal to or greater than the threshold (no in operation 1105), the electronic device 101 may control the RF circuit in operation 1109 such that the main antenna uses a DC mode. The electronic device 101 may control the RF circuit to use the DC mode based on recognizing that a received channel of the first RAT is in good condition. The electronic device 101 may perform a voice call based on a first RAT in a DC state, where the electronic device 101 uses the same antenna to connect to the first RAT and the second RAT in the DC state. Based on controlling the antenna tuning mode to the DC mode when the received strength of a first channel to which the first RAT is connected during the performance of a voice call based on the first RAT is equal to or greater than the threshold, the electronic device 101 may effectively ensure the transmission and reception performance of a first channel to which the first RAT is connected and a second channel to which the second RAT is connected. For example, based on the DC mode, the electronic device 101 may stably maintain a dual-RAT connection without SCGF by ensuring the transmission performance of the second channel (such as 5G). The DC mode may be an antenna tuning mode configured to consider the transmission and reception performance of both the first channel and the second channel. Based on setting the antenna tuning value to the DC mode, the electronic device 101 may maintain a dual-RAT connection without SCGF.

[0140] Figure 12a is a graph showing the antenna efficiency of an electronic device according to an embodiment.

[0141] In an embodiment, the electronic device 101 may set the antenna tuning value to a voice call mode or a DC mode in an EN-DC scenario. The electronic device 101 may identify whether it is in an EN-DC state. The electronic device 101 may also identify whether a VoLTE call has been executed. The electronic device 101 may identify the electric field state based on the first RAT and / or the second RAT. For example, the electronic device 101 may identify whether the electric field based on the first RAT is a strong electric field or a weak electric field. The electronic device 101 may identify whether the electric field based on the second RAT is a strong electric field or a weak electric field. For example, the electronic device 101 may perform antenna tuning in the voice call mode based on identifying that the strength of the signal received through the main antenna (e.g., the first antenna 641 or the first antenna 811) is less than a threshold. Refer to Figure 12a , curves 1210a showing the antenna efficiency of the main antenna when the electronic device 101 operates in the voice call mode and curves 1220a showing the antenna efficiency of the main antenna when the electronic device 101 operates in the DC mode are shown. In the voice call mode, the electronic device 101 may maintain a good-quality voice call service based on an increase in the antenna efficiency G1 of the first RAT (e.g., the first band (band 1) or the B66 band) and a decrease in the antenna efficiency G2 of the second RAT (e.g., the second band (band 2) or the n5 band). In the DC mode, the electronic device 101 may maintain a dual-RAT connection without SCGF based on a relative decrease in the antenna efficiency G3 of the first RAT with respect to the voice call mode and an increase in the antenna efficiency G4 of the second RAT (e.g., the n5 band) with respect to the voice call mode. Based on the DC mode, the electronic device 101 may relatively improve the transmission and reception performance of RF signals in the NR band during a VoLTE call, thereby improving the transmission performance of the second RAT (e.g., the second band or the n5 band) using the first antenna and reliably maintaining the dual-RAT connection.

[0142] Figure 12b is a graph showing the antenna efficiency of an electronic device according to an embodiment.

[0143] In an embodiment, the electronic device 101 may set the antenna tuning value to a voice call mode or a DC mode in an NE-DC scenario. The electronic device 101 may identify the strength of the received signal at the antenna based on the execution of a VoNR call in the NE-DC scenario. For example, the electronic device 101 may perform antenna tuning in the voice call mode based on identifying that the strength of the signal received through the main antenna (e.g., the first antenna 641 or the first antenna 811) is less than a threshold. Refer to Figure 12b, a curve 1210b illustrating the antenna efficiency of the main antenna when the electronic device 101 operates in a voice call mode and a curve 1220b illustrating the antenna efficiency of the main antenna when the electronic device 101 operates in a DC mode are shown. In the voice call mode, the electronic device 101 can maintain a good-quality voice call service based on the increase in the antenna efficiency of the second RAT (e.g., the second band (Band 2) or n5 band) and the decrease in the antenna efficiency G1' of the first RAT (e.g., the first band (Band 1) or B66 band). In the DC mode, the electronic device 101 can maintain a dual-RAT connection without SCGF based on the relative increase in the antenna efficiency G3' of the first RAT with respect to the voice call mode and the relative decrease in the antenna efficiency G2' of the second RAT with respect to the voice call mode. Based on the DC mode, the electronic device 101 can relatively improve the transmission and reception performance of RF signals in the LTE band during the execution of a VoNR call, thereby improving the transmission performance of the first RAT (the first band) using the first antenna and stably maintaining the dual-RAT connection. G4' The increase in and the decrease in the antenna efficiency G1' of the first RAT (e.g., the first band (Band 1) or B66 band) are used to maintain a good-quality voice call service. In the DC mode, the electronic device 101 can maintain a dual-RAT connection without SCGF based on the relative increase in the antenna efficiency G3' of the first RAT with respect to the voice call mode and the relative decrease in the antenna efficiency G2' of the second RAT with respect to the voice call mode. Based on the DC mode, the electronic device 101 can relatively improve the transmission and reception performance of RF signals in the LTE band during the execution of a VoNR call, thereby improving the transmission performance of the first RAT (the first band) using the first antenna and stably maintaining the dual-RAT connection.

[0144] Figure 13 is a flowchart (legend 1300) illustrating a method of operating an electronic device according to an embodiment.

[0145] According to an embodiment, in operation 1301, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, or the integrated communication processor 260) can establish a first connection based on the first RAT and a second connection based on the second RAT. The establishment of the first connection based on the first RAT and the second connection based on the second RAT (e.g., a DC-based connection) has been described in detail above and will not be repeated here.

[0146] In an embodiment, the electronic device 101 can identify whether a voice call based on the first RAT has been executed in operation 1303. Identifying whether a voice call based on the first RAT has been executed, e.g., identifying whether a VoLTE call or a VoNR call has been executed, has been described in detail above and will not be repeated here. In an embodiment, based on identifying that a voice call has not been executed (being "No" in operation 1303), the electronic device 101 can control the RF circuit to use the DC mode in operation 1313. The tuning of the antenna to the first RAT and the second RAT has been described in detail above, e.g., adjusting the setting value of the antenna tuning circuit to prioritize the quality of DC-based communication, and will not be repeated here.

[0147] In an embodiment, based on recognizing that a voice call has been executed (Yes in operation 1303), the electronic device 101 may recognize, in operation 1305, whether at least one recognized parameter satisfies a condition associated with the quality of the voice call. Recognizing whether at least one parameter satisfies the condition, e.g., whether at least one parameter is less than a threshold value of a numerical value indicating the quality of the received signal, has been described in detail above and will not be repeated here.

[0148] In an embodiment, when at least one parameter satisfies a condition associated with the quality of the voice call (Yes in operation 1305), the electronic device 101 may control the RF circuit to use the voice call mode in operation 1307. Tuning the antenna to the first RAT, e.g., adjusting the setting value of the antenna tuning circuit (e.g., the first antenna tuning circuit 641a and / or the antenna tuning circuit 640a) to prioritize the quality of the voice call service, has been described in detail above and will not be repeated here.

[0149] In an embodiment, when at least one parameter does not satisfy a condition associated with the quality of the voice call (No in operation 1305), the electronic device 101 may control the RF circuit to use the DC mode in operation 1309. Tuning the antenna to the first RAT and the second RAT, e.g., adjusting the setting value of the antenna tuning circuit to prioritize the quality of DC-based communication, has been described in detail above and will not be repeated here.

[0150] In an embodiment, the electronic device 101 may recognize, in operation 1311, whether the voice call has terminated. Based on recognizing that the voice call has terminated (Yes in operation 1311), the electronic device 101 may control the RF circuit to use the DC mode. For example, the electronic device 101 may control the RF circuit to switch from the voice call mode to the DC mode based on recognizing that the voice call has terminated according to operations 1307, 1311, and 1313.

[0151] In an embodiment, based on identifying that the voice call has not terminated (No in operation 1311), the electronic device 101 may identify in operation 1305 whether at least one identified parameter satisfies a condition associated with the quality of the voice call. The electronic device 101 may change the antenna tuning value based on repeating operations 1305 to 1311 until the voice call terminates. In an embodiment, the electronic device 101 may repeat operations 1305 to 1311 based on a specified period (e.g., timer expiration) and / or a specified number of times. However, the repeating method is not limited. In an embodiment, the electronic device 101 may adjust the antenna tuning value based on identifying the quality of the voice call service until the voice call terminates. For example, the electronic device 101 may change the antenna tuning value to the DC mode based on identifying that the intensity of the signal received through the main antenna is equal to or greater than a threshold, while performing antenna tuning to the voice call mode based on operations 1307, 1311, 1305, and 1309. The electronic device 101 may change the antenna tuning value to the voice call mode based on identifying that the intensity of the signal received through the main antenna is less than the threshold, while performing antenna tuning to the DC mode based on operations 1307, 1311, 1305, and 1309. The electronic device 101 may control the RF circuit to switch from the DC mode to the voice call mode to prioritize the quality of the voice call.
