In this regard, as described above, FIG. 1C shows a configuration in which an electronic device is interfaced with a plurality of base stations or network entities according to an embodiment.

Referring to FIG. 1C , 4G/5G deployment options are shown. In relation to 4G/5G deployment, when multi-RAT of 4G LTE and 5G NR is supported and in non-standalone (NSA) mode, it can be implemented as EN-DC of option 3 or NGEN-DC of option 5. On the other hand, if multi-RAT is supported and in standalone (SA) mode, it may be implemented as NE-DC of option 4. In addition, when single RAT is supported and in standalone (SA) mode, it may be implemented as NR-DC of option 2.

Regarding the base station type, the eNB is a 4G base station, also called an LTE eNB, and is based on the Rel-8 - Rel-14 standard. On the other hand, ng-eNB is an eNB capable of interworking with 5GC and gNB, also called eLTE eNB, and is based on the Rel-15 standard. In addition, gNB is a 5G base station interworking with 5G NR and 5GC, also called NR gNB, and is based on the Rel-15 standard. In addition, en-gNB is a gNB capable of interworking with EPC and eNB, also called NR gNB, and is based on the Rel-15 standard. Regarding the Dual Connectivity (DC) type, option 3 indicates E-UTRA-NR Dual Connectivity (EN-DC). On the other hand, option 7 represents NG-RAN E-UTRA-NR Dual Connectivity (NGEN-DC). In addition, option 4 indicates NR-E-UTRA Dual Connectivity (NE-DC). Also, option 2 indicates NR-NR Dual Connectivity (NR-DC). In this regard, the technical characteristics of the dual connection according to option 2 to option 7 are as follows.

- Option 2: Independent 5G service can be provided only with 5G system (5GC, gNB). In addition to eMBB (enhanced Mobile Broadband), URLLC (Ultra-Reliable Low-Latency Communication) and mMTC (Massive Machine Type Communication) communication are possible, and 5GC characteristics such as network slicing, MEC support, Mobility on demand, and Access-agnostic can be used. 5G full service can be provided. Initially, due to coverage limitations, it can be used as an overlay network or for a hot spot, enterprise use, and EPC-5GC interworking is required if it is out of 5G NR coverage. 5G NR full coverage may be provided, and dual connectivity (NR-DC) between gNBs may be supported using multiple 5G frequencies.

- Option 3: When only gNB is introduced into the existing LTE infrastructure. Core is EPC and gNB is an en-gNB capable of interworking with EPC and eNB. Dual connectivity (EN-DC) is supported between the eNB and the en-gNB, and the master node is the eNB. The eNB, which is the control anchor of the en-gNB, processes control signaling for network access, connection establishment, handover, etc. of the UE, and user traffic may be delivered through the eNB and/or en-gNB. This option is mainly applied in the first stage of 5G migration, as operators operating nationwide LTE networks can quickly build 5G networks with the introduction of en-gNB and minimal LTE upgrades without 5GC.

There are 3 types of Option 3, Option 3/3a/3x depending on the user traffic split method. Bearer split is applied to Option 3/3x and Option 3a is not applied. The main method is Option 3x.

- Option 3: Only the eNB is connected to the EPC and the en-gNB is only connected to the eNB. User traffic is split in the master node (eNB) and can be transmitted simultaneously to LTE and NR.

- Option 3a: Both the eNB and the gNB are connected to the EPC, and user traffic is delivered directly from the EPC to the gNB. User traffic is transmitted in LTE or NR.

- Option 3x: Option 3 and Option 3a are combined. The difference from Option 3 is that user traffic is split at the secondary node (gNB).

The advantages of Option 3 are i) that LTE can be used as a capacity booster for eMBB service, and ii) that the terminal is always connected to LTE, so even if it goes out of 5G coverage or the NR quality is deteriorated, service continuity is provided through LTE and stable Communication may be provided.

- Option 4: 5GC is introduced and it is still linked with LTE, but independent 5G communication is possible. The core is 5GC and the eNB is an ng-eNB capable of interworking with 5GC and gNB. Dual connectivity (NE-DC) is supported between the ng-eNB and the gNB, and the master node is the gNB. When 5G NR coverage is sufficiently expanded, LTE can be used as a capacity booster. There are 2 types of Option 4/4a. The main method is Option 4a.

- Option 7: 5GC is introduced and still works with LTE, so 5G communication depends on LTE. The core is 5GC and the eNB is an ng-eNB capable of interworking with 5GC and gNB. Dual connectivity (NGEN-DC) is supported between ng-eNB and gNB, and the master node is the eNB. 5GC characteristics can be used, and service continuity can still be provided with the eNB as the master node, as in Option 3, when 5G coverage is not yet sufficient. There are 3 types of Option 7, Option 7/7a/7x, depending on the user traffic split method. Bearer split is applied to Option 7/7x and Option 7a is not applied. The main method is Option 7x.

Hereinafter, a multi-communication system structure according to an embodiment and an electronic device having the same, in particular, an antenna in a heterogeneous radio system and an electronic device having the same will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Meanwhile, detailed operations and functions of an electronic device having a plurality of antennas according to an embodiment provided with a 4G/5G wireless communication module as shown in FIG. 2A will be reviewed below.

In the 5G communication system according to an embodiment, the 5G frequency band may be a higher frequency band than the Sub6 band. For example, the 5G frequency band may be a millimeter wave band, but is not limited thereto and may be changed according to an application.

3A illustrates an example of a configuration in which a plurality of antennas of an electronic device may be disposed according to an embodiment. Referring to FIG. 3A , a plurality of antennas 1110a to 1110d may be disposed inside or on the front side of the electronic device 100 . In this regard, the plurality of antennas 1110a to 1110d may be implemented in a form printed on a carrier inside the electronic device or may be implemented in a system-on-chip (Soc) form together with an RFIC. Meanwhile, the plurality of antennas 1110a to 1110d may be disposed on the front surface of the electronic device in addition to the inside of the electronic device. In this regard, the plurality of antennas 1110a to 1110d disposed on the front side of the electronic device 100 may be implemented as transparent antennas built into the display.

Meanwhile, a plurality of antennas 1110S1 and 1110S2 may be disposed on a side surface of the electronic device 100 . In this regard, a 4G antenna is disposed on the side of the electronic device 100 in the form of a conductive member, a slot is formed in the conductive member region, and a plurality of antennas 1110a to 1110d radiate a 5G signal through the slot. can be In addition, antennas 1150B may be disposed on the rear surface of the electronic device 100 so that the 5G signal may be radiated from the rear surface.

Meanwhile, according to the present invention, at least one signal may be transmitted or received through the plurality of antennas 1110S1 and 1110S2 on the side of the electronic device 100 . Also, according to the present invention, at least one signal may be transmitted or received through the plurality of antennas 1110a to 1110d, 1150B, 1110S1 and 1110S2 on the front and/or side of the electronic device 100 . The electronic device may communicate with the base station through any one of the plurality of antennas 1110a to 1110d, 1150B, 1110S1, and 1110S2. Alternatively, the electronic device may perform multiple input/output (MIMO) communication with the base station through two or more antennas among the plurality of antennas 1110a to 1110d, 1150B, 1110S1 and 1110S2.

3B illustrates a configuration of a wireless communication unit of an electronic device operable in a plurality of wireless communication systems according to an embodiment. Referring to FIG. 3B , the electronic device includes a first power amplifier 1210 , a second power amplifier 1220 , and an RFIC 1250 . In addition, the electronic device may further include a modem (Modem, 1400) and an application processor (AP: Application Processor, 500). Here, the modem (Modem, 1400) and the application processor (AP, 1500) may be physically implemented on a single chip, and may be implemented in a logically and functionally separated form. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.

Meanwhile, the electronic device includes a plurality of low noise amplifiers (LNAs) 1410 to 1440 in the receiver. Here, the first power amplifier 1210 , the second power amplifier 1220 , the controller 1250 , and the plurality of low-noise amplifiers 310 to 340 are all operable in the first communication system and the second communication system. In this case, the first communication system and the second communication system may be a 4G communication system and a 5G communication system, respectively.

As shown in FIG. 2B , the RFIC 1250 may be configured as a 4G/5G integrated type, but is not limited thereto and may be configured as a 4G/5G separate type according to an application. When the RFIC 1250 is configured as a 4G/5G integrated type, it is advantageous in terms of synchronization between 4G/5G circuits, as well as the advantage that control signaling by the modem 1400 can be simplified.

Meanwhile, when the RFIC 1250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the difference between the 5G band and the 4G band is large, such as when the 5G band is configured as a millimeter wave band, the RFIC 1250 may be configured as a 4G/5G separate type. As such, when the RFIC 1250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

On the other hand, even when the RFIC 1250 is configured as a 4G/5G separate type, the 4G RFIC and the 5G RFIC are logically and functionally separated, and it is also possible to be physically implemented on a single chip.

Meanwhile, the application processor (AP) 1450 is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 1500 may control the operation of each component of the electronic device through the modem 1400 .

For example, the modem 1400 may be controlled through a power management IC (PMIC) for low power operation of the electronic device. Accordingly, the modem 1400 may operate the power circuits of the transmitter and the receiver in the low power mode through the RFIC 1250 .

In this regard, when it is determined that the electronic device is in an idle mode, the application processor (AP) 500 may control the RFIC 1250 through the modem 300 as follows. For example, if the electronic device is in an idle mode, the RFIC through the modem 300 so that at least one of the first and second power amplifiers 110 and 120 operates in the low power mode or is turned off (1250) can be controlled.

According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP) 500 may control the modem 300 to provide wireless communication capable of low power communication. For example, when the electronic device is connected to a plurality of entities among a 4G base station, a 5G base station, and an access point, the application processor (AP) 1450 may control the modem 1400 to enable wireless communication with the lowest power. Accordingly, the application processor (AP) 500 may control the modem 1400 and the RFIC 1250 to perform short-distance communication using only the short-range communication module 113 even though the throughput is somewhat sacrificed.

According to another embodiment, when the remaining battery level of the electronic device is equal to or greater than a threshold, the modem 1400 may be controlled to select an optimal wireless interface. For example, the application processor (AP) 1590 may control the modem 1400 to receive through both the 4G base station and the 5G base station according to the remaining battery level and available radio resource information. In this case, the application processor (AP) 1500 may receive the remaining battery level information from the PMIC, and the available radio resource information from the modem 1400 . Accordingly, if the remaining battery level and available radio resources are sufficient, the application processor (AP) 500 may control the modem 1400 and the RFIC 1250 to receive through both the 4G base station and the 5G base station.

Meanwhile, the multi-transceiving system of FIG. 3B may integrate the transmitter and receiver of each radio system into one transceiver. Accordingly, there is an advantage that a circuit part integrating two types of system signals in the RF front-end can be removed.

In addition, since the front-end components can be controlled by the integrated transceiver, the front-end components can be more efficiently integrated than when the transmission/reception system is separated for each communication system.

In addition, when each communication system is separated, it is impossible to control other communication systems as necessary, or efficient resource allocation is impossible because the system delay is increased. On the other hand, the multi-transmission/reception system as shown in FIG. 2 has the advantage that it is possible to control other communication systems as necessary, and thus system delay can be minimized, so that efficient resource allocation is possible.

Meanwhile, the first power amplifier 1210 and the second power amplifier 1220 may operate in at least one of the first and second communication systems. In this regard, when the 5G communication system operates in the 4G band or the Sub6 band, the first and second power amplifiers 1220 may operate in both the first and second communication systems.

On the other hand, when the 5G communication system operates in the millimeter wave (mmWave) band, one of the first and second power amplifiers 1210 and 1220 operates in the 4G band, and the other operates in the millimeter wave band. have.

Meanwhile, by integrating the transceiver and the receiving unit, two different wireless communication systems can be implemented with one antenna by using an antenna for both transmitting and receiving. In this case, 4x4 MIMO can be implemented using four antennas as shown in FIG. 2 . In this case, 4x4 DL MIMO may be performed through the downlink (DL).

Meanwhile, if the 5G band is the Sub6 band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in both the 4G band and the 5G band. On the other hand, if the 5G band is a millimeter wave (mmWave) band, the first to fourth antennas ANT1 to ANT4 may be configured to operate in any one of the 4G band and the 5G band. In this case, if the 5G band is a millimeter wave (mmWave) band, each of a plurality of separate antennas may be configured as an array antenna in the millimeter wave band.

Meanwhile, 2x2 MIMO can be implemented using two antennas connected to the first power amplifier 1210 and the second power amplifier 1220 among the four antennas. In this case, 2x2 UL MIMO (2 Tx) may be performed through the uplink (UL). Alternatively, it is not limited to 2x2 UL MIMO, and may be implemented with 1 Tx or 4 Tx. In this case, when the 5G communication system is implemented with 1 Tx, only one of the first and second power amplifiers 1210 and 1220 needs to operate in the 5G band. On the other hand, when the 5G communication system is implemented as 4Tx, an additional power amplifier operating in the 5G band may be further provided. Alternatively, a transmission signal may be branched in each of one or two transmission paths, and the branched transmission signal may be connected to a plurality of antennas.

On the other hand, since a switch-type splitter or a power divider is built inside the RFIC corresponding to the RFIC 1250, there is no need for a separate component to be disposed outside, thereby improving component mountability. can Specifically, by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the controller 1250 , it is possible to select the transmitter (TX) of two different communication systems.

In addition, the electronic device operable in a plurality of wireless communication systems according to an embodiment may further include a duplexer 1231 , a filter 1232 , and a switch 1233 .

The duplexer 1231 is configured to mutually separate signals of a transmission band and a reception band. At this time, the signals of the transmission band transmitted through the first and second power amplifiers 1210 and 1220 are applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 1231 . On the other hand, signals of the reception band received through the antennas ANT1 and ANT4 are received by the low noise amplifiers 310 and 340 through the second output port of the duplexer 1231 .

The filter 1232 may be configured to pass a signal of a transmission band or a reception band and block a signal of the remaining band. In this case, the filter 1232 may include a transmit filter connected to a first output port of the duplexer 1231 and a receive filter connected to a second output port of the duplexer 1231 . Alternatively, the filter 1232 may be configured to pass only a signal of a transmission band or only a signal of a reception band according to the control signal.

The switch 1233 is configured to transmit either only a transmit signal or a receive signal. In an embodiment of the present invention, the switch 1233 may be configured in a single pole double throw (SPDT) type to separate a transmission signal and a reception signal in a time division multiplexing (TDD) method. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 1231 may be implemented in the form of a circulator.

On the other hand, in another embodiment of the present invention, the switch 1233 is also applicable to a frequency division multiplexing (FDD: Time Division Duplex) scheme. In this case, the switch 1233 may be configured in a double pole double throw (DPDT) type to connect or block a transmission signal and a reception signal, respectively. Meanwhile, since a transmission signal and a reception signal can be separated by the duplexer 1231 , the switch 1233 is not necessarily required.

Meanwhile, the electronic device according to an embodiment may further include a modem 1400 corresponding to a control unit. In this case, the RFIC 1250 and the modem 1400 may be referred to as a first controller (or first processor) and a second controller (second processor), respectively. Meanwhile, the RFIC 1250 and the modem 1400 may be implemented as physically separate circuits. Alternatively, the RFIC 1250 and the modem 1400 may be physically or logically divided into one circuit.

The modem 1400 may control and process signals for transmission and reception of signals through different communication systems through the RFIC 1250 . The modem 1400 may be obtained through control information received from the 4G base station and/or the 5G base station. Here, the control information may be received through a physical downlink control channel (PDCCH), but is not limited thereto.

The modem 1400 may control the RFIC 1250 to transmit and/or receive a signal through the first communication system and/or the second communication system in a specific time and frequency resource. Accordingly, the RFIC 1250 may control transmission circuits including the first and second power amplifiers 1210 and 1220 to transmit a 4G signal or a 5G signal in a specific time period. Also, the RFIC 1250 may control receiving circuits including the first to fourth low-noise amplifiers 1410 to 1440 to receive a 4G signal or a 5G signal in a specific time period.

Meanwhile, the application program operating in the electronic device described in this specification may be driven in association with a user space, a kernel space, and hardware. In this regard, FIG. 4 shows a framework structure related to an application program operating in an electronic device according to an exemplary embodiment. The program module 410 may include a kernel 420 , middleware 430 , an API 450 , a framework/library 460 , and/or an application 470 . At least a portion of the program module 410 may be pre-loaded on the electronic device or downloaded from an external device or server.

The kernel 420 may include a system resource manager 421 and/or a device driver 423 . The system resource manager 421 may control, allocate, or recover system resources. According to an embodiment, the system resource manager 421 may include a process manager, a memory manager, or a file system manager. The device driver 423 may include a display driver, a camera driver, a Bluetooth driver, a shared memory driver, a USB driver, a keypad driver, a WiFi driver, an audio driver, or an inter-process communication (IPC) driver. The middleware 430 provides, for example, functions commonly required by the applications 470 or provides various functions through the API 460 so that the applications 470 can use limited system resources inside the electronic device. It may be provided as an application 470 .

The middleware 430 includes a runtime library 425 , an application manager 431 , a window manager 432 , a multimedia manager 433 , a resource manager 434 , a power manager 435 , a database manager 436 , a package manager ( 437 ), connectivity manager 438 , notification manager 439 , location manager 440 , graphic manager 441 , security manager 442 , content manager 443 , service manager 444 or an external device manager It may include at least one of (445).

The framework/library 450 may include a general-purpose framework/library 451 and a special-purpose framework/library 452 . Here, the general-purpose framework/library 451 and the special-purpose framework/library 452 may be referred to as a first framework/library 451 and a second framework/library 452 , respectively. The first framework/library 451 and the second framework/library 452 may interface with the kernel space and hardware through the first API 461 and the second API 462, respectively. Here, the second framework/library 452 may be an example software architecture that may modularize artificial intelligence (AI) functions. Using the architecture, various processing blocks of hardware implemented as a System on Chip (SoC) (eg, CPU 422, DSP 424, GPU 426, and/or NPU 428) to support operations during runtime operation of the application 470 .

Application 470 may include, for example, home 471 , dialer 472 , SMS/MMS 473 , instant message (IM) 474 , browser 475 , camera 476 , alarm 477 . , Contact (478), Voice Dial (479), Email (480), Calendar (481), Media Player (482), Album (483), Watch (484), Payment (485), Accessory Management (486) ), health care, or environmental information providing applications.

The AI application may be configured to call functions defined in user space that may provide detection and recognition of a scene indicating the location in which the electronic device is currently operating. The AI application may configure the microphone and camera differently depending on whether the recognized scene is an indoor space or an outdoor space. The AI application may make a request for compiled program code associated with a library defined in the Scene Detect application programming interface (API) to provide an estimate of the current scene. Such a request may rely on the output of a deep neural network configured to provide scene estimates based on video and positioning data.

The framework/library 462 , which may be compiled code of the Runtime Framework, may be further accessible by the AI application. The AI application may cause the runtime framework engine to request a scene estimate at specific time intervals, or triggered by an event detected by the application's user interface. When estimating a scene, the runtime engine may then send a signal to an operating system such as a Linux Kernel running on the SoC. The operating system may cause the operation to be performed on the CPU 422 , DSP 424 , GPU 426 , NPU 428 , or some combination thereof. The CPU 422 may be accessed directly by the operating system, and other processing blocks may be accessed through a driver, such as the DSP 424 , the GPU 426 , or the driver 414 - 418 for the NPU 428 . may be In the illustrative example, deep neural networks and AI algorithms may be configured to run on a combination of processing blocks, such as CPU 422 and GPU 426 , or AI algorithms, such as deep neural networks, may be configured to run on NPU 428 . may be executed.

The AI algorithm performed through the special-purpose framework/library as described above may be performed only by an electronic device or may be performed by a server supported scheme. When the AI algorithm is performed by the server support method, the electronic device may receive and transmit information related to the AI server and AI processing through the 4G/5G communication system.

Meanwhile, referring to FIGS. 1A and 2A , a 5G wireless communication system, that is, 5G new radio access technology (NR) may be provided. In this regard, as more and more communication devices require a larger communication capacity, there is a need for improved mobile broadband communication compared to the existing radio access technology. In addition, massive MTC (Machine Type Communications), which provides various services anytime, anywhere by connecting multiple devices and objects, is also one of the major issues to be considered in next-generation communication. In addition, communication system design considering reliability and latency sensitive service/terminal is being discussed. As described above, the introduction of next-generation radio access technology considering eMBB (enhanced mobile broadband communication), Mmtc (massive MTC), URLLC (Ultra-Reliable and Low Latency Communication), etc. is being discussed, and in this specification, the technology is referred to as NR for convenience. . NR is an expression showing an example of 5G radio access technology (RAT).

A new RAT system including NR uses an OFDM transmission scheme or a similar transmission scheme. The new RAT system may follow OFDM parameters different from those of LTE. Alternatively, the new RAT system may follow the existing numerology of LTE/LTE-A, but may have a larger system bandwidth (eg, 100 MHz). Alternatively, one cell may support a plurality of numerologies. That is, terminals operating in different numerology may coexist in one cell.

In this regard, in the case of 4G LTE, since the maximum bandwidth of the system is limited to 20 MHz, a single sub-carrier spacing (SCS) of 15 KHz is used. However, in the case of 5G NR, since a channel bandwidth of 5 MHz to 400 MHz is supported, FFT processing complexity may increase to process the entire bandwidth through one subcarrier interval. Accordingly, the subcarrier interval used for each frequency band may be extended and applied.

Numerology corresponds to one subcarrier spacing in the frequency domain. By scaling the reference subcarrier spacing by an integer N, different numerology can be defined. In this regard, Fig. 5A shows an example of a frame structure in NR. Meanwhile, FIG. 5B shows a change in the slot length according to a change in the subcarrier spacing in NR.

An NR system can support multiple numerologies. Here, the numerology may be defined by a subcarrier spacing and a cyclic prefix (CP) overhead. In this case, the plurality of subcarrier intervals may be derived by scaling the basic subcarrier interval by an integer N (or μ). Also, although it is assumed that very low subcarrier spacing is not used at very high carrier frequencies, the numerology used can be selected independently of the frequency band. In addition, in the NR system, various frame structures according to a number of numerologies may be supported.

Hereinafter, an Orthogonal Frequency Division Multiplexing (OFDM) numerology and frame structure that can be considered in an NR system will be described. A number of OFDM numerologies supported in the NR system may be defined as shown in Table 1.

μ	△f =2 m * 15 [kHz]	Cyclic prefix (CP)
0	15	Normal
One	30	Normal
2	60	Normal, Extended
3	120	Normal
4	240	Normal

NR supports multiple numerology (or subcarrier spacing (SCS)) to support various 5G services. For example, when SCS is 15kHz, it supports wide area in traditional cellular bands, and when SCS is 30kHz/60kHz, dense-urban, lower latency and a wider carrier bandwidth, and when the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz to overcome phase noise. The NR frequency band is defined as a frequency range of two types (FR1, FR2). FR1 is the sub 6GHz range, and FR2 is the above 6GHz range, which may mean millimeter wave (mmW). Table 2 below shows the definition of the NR frequency band.

Frequency Range designation	Corresponding frequency range	Subcarrier Spacing
FR1	450MHz - 6000MHz	15, 30, 60 kHz
FR2	24250MHz - 52600MHz	60, 120, 240 kHz

With respect to the frame structure in the NR system, the sizes of various fields in the time domain are expressed as multiples of a specific time unit. 3A is an example of SCS of 60 kHz, and one subframe may include four slots. One subframe = {1,2,4} slots shown in FIG. 3 is an example, and the number of slot(s) that can be included in one subframe may be one, two, or four. In addition, the mini-slot may include 2, 4, or 7 symbols, or more or fewer symbols. Referring to FIG. 5B, the subcarrier spacing of 5G NR phase I and the OFDM symbol length accordingly indicates. Each subcarrier interval is extended by a power of 2, and the symbol length is reduced in inverse proportion to this. In FR1, subcarrier spacings of 15 kHz, 30 kHz and 60 kHz are available depending on the frequency band/bandwidth. In FR2, 60 kHz and 120 kHz can be used for data channels and 240 kHz can be used for a synchronization signal. In 5G NR, the basic unit of scheduling is defined as a slot, and the number of OFDM symbols included in one slot is determined. Regardless of the subcarrier spacing, 14 may be limited as shown in FIG. 5A or FIG. 5B. Referring to FIG. 3B , when a wide subcarrier interval is used, the length of one slot is shortened in inverse proportion to reduce transmission delay in a radio section. In addition, for efficient support of ultra reliable low latency communication (uRLLC), scheduling in units of minislots (eg, 2, 4, 7 symbols) may be supported as described above in addition to scheduling in units of slots. Considering the above-described technical features Then, in 5G NR described in this specification, the slot may be provided at the same interval as the slot of 4G LTE, or may be provided as slots of various sizes. As an example, the slot interval in 5G NR may be configured as 0.5 ms, which is the same as the slot interval of 4G LTE. As another example, the slot interval in 5G NR may be configured as 0.25 ms, which is a narrower interval than the slot interval of 4G LTE.

In this regard, the 4G communication system and the 5G communication system may be referred to as a first communication system and a second communication system, respectively. Accordingly, the first signal (first information) of the first communication system may be a signal (information) in a 5G NR frame with a slot interval scalable to 0.25 ms, 0.5 ms, or the like. On the other hand, the second signal (second information) of the second communication system may be a signal (information) in a 4G LTE frame with a fixed slot interval of 0.5 ms.

Meanwhile, the first signal of the first communication system may be transmitted and/or received through a maximum bandwidth of 20 MHz. On the other hand, the second signal of the second communication system may be transmitted and/or received through a variable channel bandwidth from 5 MHz to 400 MHz. In this regard, the first signal of the first communication system may be FFT-processed with a single sub-carrier spacing (Sub-Carrier Spacing, SCS) of 15 KHz.

On the other hand, the second signal of the second communication system may be FFT-processed at subcarrier intervals of 15 kHz, 30 kHz, and 60 kHz according to the frequency band/bandwidth. In this case, the second signal of the second communication system may be modulated and frequency-converted to the FR1 band and transmitted through the 5G Sub6 antenna. Meanwhile, the FR1 band signal received through the 5G Sub6 antenna may be frequency-converted and demodulated. Thereafter, the second signal of the second communication system may be IFFT-processed at subcarrier intervals of 15 kHz, 30 kHz, and 60 kHz according to the frequency band/bandwidth.

Meanwhile, the second signal of the second communication system may be FFT-processed at subcarrier intervals of 60 kHz, 120 kHz, and 240 kHz according to frequency band/bandwidth and data/synchronization channel. In this case, the second signal of the second communication system may be modulated to the FR2 band and transmitted through the 5G mmWave antenna. On the other hand, the FR2 band signal received through the 5G mmWave antenna can be frequency-converted and demodulated. Thereafter, the second signal of the second communication system may be IFFT-processed through subcarrier intervals of 60 kHz, 120 kHz, and 240 kHz according to frequency band/bandwidth and data/synchronization channel.

In 5G NR, symbol-level temporal alignment can be used for transmission schemes using various slot lengths, mini-slots, and different subcarrier spacings. Accordingly, it provides flexibility for efficiently multiplexing various communication services such as enhancement mobile broadband (eMBB) and ultra reliable low latency communication (uRLLC) in the time domain and frequency domain. Also, unlike 4G LTE, 5G NR may define uplink/downlink resource allocation at a symbol level in one slot as shown in FIG. 3 . In order to reduce hybrid automatic repeat request (HARQ) delay, a slot structure capable of transmitting HARQ ACK/NACK directly within a transmission slot may be defined. Such a slot structure may be referred to as a self-contained structure.

Unlike 4G LTE, 5G NR can support a common frame structure constituting an FDD or TDD frame through a combination of various slots. Accordingly, the transmission direction of an individual cell can be freely and dynamically adjusted according to traffic characteristics by introducing a dynamic TDD scheme.

In relation to switching between dual SIMs according to the present specification, a random access procedure of an electronic device, that is, a terminal can be summarized as shown in Table 3 and FIG. 6A .

	type of signal	Actions/Information Acquired
Step 1	PRACH preamble in UL	* Initial beam acquisition* Random selection of RA-preamble ID
Step 2	Random Access Response on DL-SCH	* Timing Alignment Information* RA-Preamble ID* Initial UL Grant, Temporary C-RNTI
Step 3	UL transmission on UL-SCH	* RRC connection request* terminal identifier
Step 4	Contention Resolution on DL	* Temporary C-RNTI on PDCCH for initial access * C-RNTI on PDCCH for UE in RRC_CONNECTED

6A illustrates an example of a random access procedure according to an embodiment.

First, the UE may transmit the PRACH preamble as Msg1 of the random access procedure in the UL.

Random access preamble sequences having two different lengths are supported. Long sequence length 839 applies as subcarrier spacing of 1.25 and 5 kHz, and short sequence length 139 applies as subcarrier spacing of 15, 30, 60 and 120 kHz. A long sequence supports both an unrestricted set and a limited set of types A and B, whereas a short sequence supports only an unrestricted set.

A number of RACH preamble formats are defined with one or more RACH OFDM symbols, and different cyclic prefixes and guard times. A PRACH preamble configuration for use is provided to the terminal in the system information.

If there is no response to Msg1, the UE may retransmit the PRACH preamble within a predetermined number of times by power ramping. The UE calculates the PRACH transmission power for retransmission of the preamble based on the most recent path loss and power ramping counter. When the UE performs beam switching, the power ramping counter is maintained unchanged.

The system information informs the UE of the association between the SS block and the RACH resource.

6B is a conceptual diagram illustrating a concept of a threshold value for an SS block for RACH resource association.

The threshold of SS block for RACH resource association is based on RSRP and configurable network. Transmission or retransmission of the RACH preamble is based on SS blocks that meet a threshold. Referring to FIG. 6B , in relation to detection of SS blocks above or below a threshold, different beams may be used in the mmWave band. Alternatively, the UE operating in the Sub6 band as shown in FIG. 3B may detect SS blocks with a single beam through a single antenna.

When the UE receives a random access response on the DL-SCH, the DL-SCH may provide timing alignment information, an RA-preamble ID, an initial UL grant, and a temporary C-RNTI.

Based on this information, the UE may transmit UL transmission on the UL-SCH as Msg3 of the random access procedure. Msg3 may include an RRC connection request and a terminal identifier.

In response, the network may send Msg4, which may be treated as a contention resolution message on the DL. By receiving this, the terminal may enter an RRC connected state.

A detailed description of each step is given below:

Before starting the physical random access procedure, Layer-1 should receive a set of SS / PBCH block indices from a higher layer, and provide a set of RSRP measurements corresponding to this to a higher layer.

Before initiating a physical random access procedure, Layer-1 must receive the following information from a higher layer:

- Configuration of Physical Random Access Channel (PRACH) transmission parameters (PRACH preamble form for PRACH transmission, time resource, and frequency resource).

- Root sequences in the PRACH preamble sequence set (index into logical root sequence table, cyclic shift (Ncs), and type of set (unrestricted set, restricted set A, or restricted set B)) and their cyclic Parameters for determining the shift.

From the point of view of the physical layer, the L1 random access procedure includes transmission of a random access preamble (Msg1) in PRACH, a random access response (RAR) message with PDCCH/PDSCH (Msg2), and, if applicable, Msg3 PUSCH for contention resolution, and transmission of PDSCH.

Hereinafter, in relation to the configuration having a threshold value according to the RACH procedure and signal quality as shown in FIGS. 6A and 6B, an electronic device that performs switching between dual Subscriber Identification Modules (SIMs) will be described. decide to do

In this regard, the electronic device may be configured to provide 5G communication services in various frequency bands. Recently, attempts have been made to provide a 5G communication service using the Sub6 band below the 6GHz band. Meanwhile, some of the LTE frequency bands may be allocated to provide 5G communication services.

Alternatively, each SIM card may support a heterogeneous RAT case in the electronic device performing switching between dual SIMs according to the present specification.

Meanwhile, the dual SIM according to the present specification may be a SIM card that can be inserted into an electronic device.

Meanwhile, the dual SIM according to the present specification may be connected to different networks operated by different operators. Alternatively, the dual SIM according to the present specification may be connected to the same or different networks operated by the same operator.

7 illustrates a detailed configuration of an electronic device performing switching between dual SIMs according to the present specification. Referring to FIG. 7 , an electronic device may be configured to include a transceiver 1250 and a processor 1400 . Also, the electronic device may be configured to further include a Subscriber Identification Module (SIM) 160 (refer to FIG. 2 ) and a display 151 .

The first processor 1400a may be a modem that performs a communication function. The first processor 1400 may interwork with the framework/library 460 and the middleware 430 of FIG. 4 . Specifically, the first processor 1400a may work with the framework/library 460 and the middleware 430 of FIG. 4 to perform a communication function related to call connection establishment/release.

The second processor 1400b may be configured to include a plurality of call related control modules 1410 to 1460 . The second processor 1400b includes a call application module 1410 , a subscriber identification and UI display module 1420 , a setup failure detection module 1430 , a call connection interruption analysis module 1440 , a voice quality monitoring module 1450 and a parameter It may be configured to include at least one of the monitoring module 1460 . A detailed operation of such a detailed module will be described in detail with reference to FIGS. 9 to 11 .

The transceiver 1250 may be configured to transmit and receive signals with a wireless communication network. The processor 1400 may be configured to monitor a parameter associated with a connection or access status with a wireless communication network. In addition, the processor 1400 may be configured to perform a call connection or access through another subscriber identification module (SIM) 160 based on the monitored parameter.

In this regard, a method of switching between dual SIMs may be performed by a modem and/or a processor interworking therewith. 8 is a flowchart of a method for performing switching between dual SIMs according to the present specification. Referring to FIG. 8 , the method for switching between dual SIMs may include a parameter monitoring step S110 , a parameter processing step S120 , and a reconnection identification step S130 . In addition, the method for switching between dual SIMs may include an optimal subscription SIM identification step (S140) and a notification step (S150). In this regard, the order of the above-described steps is not limited and may be changed according to applications. As an example, in the method, after the optimal subscription SIM identification step S140 is performed, the reconnection identification step S130 may be performed.

In the parameter monitoring step ( S110 ), a parameter associated with a connection or access state with a wireless communication network may be monitored. The connection or access status may be processed/analyzed based on the parameter associated with the monitored connection or access status in the parameter processing step S120 . Based on the parameter monitored in the reconnection identification step (S130), it is possible to identify/determine whether to reconnect (eg, whether to re-transmit through re-dial).

In the optimal subscription SIM identification step ( S140 ), based on the monitored parameters, it is possible to identify/determine whether to perform a call connection or access through another subscriber identification module (SIM) 160 . In the notification step (S150), it is possible to notify/indicate that a call connection or access has been made through the corresponding SIM.

Meanwhile, various embodiments related to a method of performing call connection or access through another subscriber identification module (SIM) 160 based on the monitored parameter will be described as follows. 9 to 11 are flowcharts of a method of performing a call connection or access through another SIM based on a monitored parameter according to various embodiments of the present disclosure. 9 is a flowchart illustrating a method for switching between dual SIMs when connection setup fails. 10 is a flowchart illustrating a method for switching between dual SIMs when an ongoing call is disconnected. 11 is a flowchart illustrating a method for switching between dual SIMs according to whether the quality of an on-going call is deteriorated. Meanwhile, FIG. 12 shows a specific method of performing optimal subscription identification in relation to FIGS. 9 to 11 .

Referring to FIG. 9 , in the parameter monitoring step ( S210 ), a parameter related to a connection or access state with a wireless communication network may be monitored. In this regard, it may be assumed that the first SIM card and the second SIM card exist, and a default call is made using the first SIM card. In addition, the connection failure detection triggering condition may be RACH failure, RRC failure, service barring or call setup or No service rejected by the network (NW). In this regard, when the value of the failure detected field of the parameter of the corresponding message is yes, connection failure may be detected.

In this regard, receiving and monitoring parameters related to random access channel (RACH) failure, access class barring, radio link failure (RLF), service status or service refusal from the wireless communication network (S210) )can do. Accordingly, it is possible to determine the call setup state based on the parameter ( S220 ).

Alternatively, a parameter associated with RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), or RSRI (Reference Signal Received Indicator) may be received and monitored from a base station belonging to a communication network (S210). Accordingly, it is possible to determine the call setup state based on the parameter ( S220 ).

In the above, an electronic device that performs switching between dual SIMs according to various embodiments has been described. A wireless communication system including an electronic device and a base station performing such a dual SIM conversion will be described below. In this regard, FIG. 18 illustrates a block diagram of a wireless communication system to which the methods proposed in the present specification can be applied.

Referring to FIG. 18 , the wireless communication system includes a first communication device 910 and/or a second communication device 920 . 'A and/or B' may be interpreted as having the same meaning as 'including at least one of A or B'. The first communication device may represent the base station and the second communication device may represent the terminal (or the first communication device may represent the terminal and the second communication device may represent the base station).

Base station (BS) is a fixed station (fixed station), Node B, evolved-NodeB (eNB), gNB (Next Generation NodeB), BTS (base transceiver system), access point (AP: Access Point), gNB (general) NB), 5G system, network, AI system, RSU (road side unit), may be replaced by terms such as robot. In addition, the terminal (Terminal) may be fixed or have mobility, UE (User Equipment), MS (Mobile Station), UT (user terminal), MSS (Mobile Subscriber Station), SS (Subscriber Station), AMS (Advanced Mobile) Station), WT (Wireless terminal), MTC (Machine-Type Communication) device, M2M (Machine-to-Machine) device, D2D (Device-to-Device) device, vehicle, robot, AI module may be replaced by terms such as

The first communication device and the second communication device include a processor 911,921, a memory 914,924, one or more Tx/Rx radio frequency modules 915,925, Tx processors 912,922, Rx processors 913,923 , including antennas 916 and 926 . The processor implements the functions, processes and/or methods salpinned above. More specifically, in DL (communication from a first communication device to a second communication device), an upper layer packet from the core network is provided to the processor 911 . The processor implements the functions of the L2 layer. In DL, the processor provides multiplexing between logical channels and transport channels, allocation of radio resources to the second communication device 920, and is responsible for signaling to the second communication device. A transmit (TX) processor 912 implements various signal processing functions for the L1 layer (ie, the physical layer). The signal processing function facilitates forward error correction (FEC) in the second communication device, and includes coding and interleaving. The coded and modulated symbols are divided into parallel streams, each stream mapped to OFDM subcarriers, multiplexed with a reference signal (RS) in the time and/or frequency domain, and using Inverse Fast Fourier Transform (IFFT) are combined together to create a physical channel carrying a stream of time domain OFDMA symbols. The OFDM stream is spatially precoded to generate multiple spatial streams. Each spatial stream may be provided to a different antenna 916 via a separate Tx/Rx module (or transceiver) 915 . Each Tx/Rx module may modulate an RF carrier with a respective spatial stream for transmission. In the second communication device, each Tx/Rx module (or transceiver) 925 receives a signal via each antenna 926 of each Tx/Rx module. Each Tx/Rx module recovers information modulated with an RF carrier and provides it to a receive (RX) processor 923 . The RX processor implements the various signal processing functions of layer 1. The RX processor may perform spatial processing on the information to recover any spatial streams destined for the second communication device. If multiple spatial streams are destined for the second communication device, they may be combined into a single OFDMA symbol stream by multiple RX processors. The RX processor uses a Fast Fourier Transform (FFT) to transform the OFDMA symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDMA symbol stream for each subcarrier of the OFDM signal. The symbols and reference signal on each subcarrier are recovered and demodulated by determining the most probable signal placement points transmitted by the first communication device. These soft decisions may be based on channel estimate values. The soft decisions are decoded and deinterleaved to recover the data and control signal originally transmitted by the first communication device on the physical channel. Corresponding data and control signals are provided to a processor 921 .

The UL (second communication device to first communication device) is handled in the first communication device 910 in a manner similar to that described with respect to the receiver function in the second communication device 920 . Each Tx/Rx module 925 receives a signal via a respective antenna 926 . Each Tx/Rx module provides an RF carrier and information to the RX processor 923 . The processor 921 may be associated with a memory 924 that stores program code and data. Memory may be referred to as a computer-readable medium.
