     TECHNICAL FIELD 
     Various example embodiments relate to an electronic device and/or a method of operating the electronic device, and more particularly for example, to technology for scheduling data transmission and/or reception through a plurality of links. 
     BACKGROUND 
     With the spread of various electronic devices, speed improvement for wireless communication that may be used by various electronic devices has been implemented. Among wireless communications supported by recent electronic devices, IEEE 802.11 WLAN (or Wi-Fi) is a standard for implementing high-speed wireless connection on various electronic devices. First implemented Wi-Fi could support a transmission rate of up to 1 to 9 Mbps, but Wi-Fi 6 technology (or IEEE 802.11 ax) can support a transmission rate of up to about 10 Gbps. 
     An electronic device may support various services (e.g., UHD video streaming service, augmented reality (AR) service, virtual reality (VR) service, and/or a mixed reality (MR) service) using data of a relatively large capacity through wireless communication supporting a high transmission rate. 
     The IEEE 802.11 ax technical standard introduced a target wake time (TWT) function so as to improve a battery performance of various electronic devices connected to an access point (AP). The TWT function may be a function of transmitting or receiving data between the electronic device and the AP during a designated time (target wake time duration). The electronic device may transmit or receive data during a designated time, and may not transmit or receive data during a time other than the designated time. The TWT function is attracting attention as a function capable of reducing power consumption generating when an electronic device performs short-range wireless communication. 
     Short-range wireless communication defined in IEEE 802.11 can support various functions (e.g., power management mode or automatic power save delivery (APSD) mode) that can reduce power consumption by performing data transmission and/or reception after transmitting a designated signal in addition to the TWT function. 
     SUMMARY 
     An electronic device may perform group owner (GO) negotiation as part of a process of being connected, directly or indirectly, to an external electronic device through short-range wireless communication (e.g., Wi-Fi), and select a channel to be established between the electronic device and the external electronic device based on data exchanged in a negotiation process. 
     In a state in which the electronic device is connected, directly or indirectly, to an access point (AP), the electronic device may perform GO negotiation with an external electronic device. 
     In case that the electronic device is connected, directly or indirectly, to an external electronic device through a channel of a frequency band different from a channel between the electronic device and the AP, the electronic device may operate with an AP and then be switched to an STA so as to transmit or receive data to the AP. 
     In case that the electronic device does not support a function (e.g., real simultaneous dual band (RSDB)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands, the electronic device may not transmit or receive data simultaneously using a link between the electronic device and the AP and a link between the electronic device and the external electronic device. 
     In case that scheduling of data transmission and/or reception through a plurality of links is not appropriately performed, the electronic device may be scheduled to perform data transmission and/or reception through another link while performing data transmission and/or reception through one link. In the above situation, the electronic device may not transmit and/or receive data through another link during a time scheduled to transmit and/or receive data through another link, and a situation in which data transmission and/or reception speed is lowered and in which a quality of a service is lowered may occur. 
     According to various example embodiments, an electronic device may include a communication circuit configured to transmit and receive data to and from a first external electronic device through a first link of short-range wireless communication while the electronic device operates in a soft AP mode and to transmit and receive data to and from a second external electronic device through a second link of the short-range wireless communication while the electronic device operates in an STA mode; and a processor, wherein the processor may be configured to identify a control technique/method of the first link and the second link, and to configure at least one parameter related to a period during which data transmission and/or reception through the second link is available based on at least one parameter related to a period during which data transmission and/or reception through the first link is available corresponding to identifying that the control technique/method does not simultaneously perform data transmission and/or reception through the first link and the second link. 
     According to various example embodiments, a method of operating an electronic device may include identifying a control method of a first link used for transmitting and receiving data to and from a first external electronic device while the electronic device operates in a soft AP mode and a second link used for transmitting and receiving data to and from a second external electronic device while the electronic device operates in an STA mode; and configuring at least one parameter related to a period during which data transmission and/or reception through the second link is available/possible based on at least one parameter related to a period during which data transmission and/or reception through the first link is available/possible corresponding to identifying that the control method does not simultaneously perform data transmission and/or reception through the first link and the second link. 
     An electronic device and a method of operating the electronic device according to various example embodiments can configure at least one parameter related to a period during which data transmission and/or reception through the second link is available/possible based on at least one parameter related to a period during which data transmission and/or reception through the first link is available/possible according to identifying that a control technique/method of the first link and the second link does not simultaneously perform data transmission and/or reception through the first link and the second link. In particular, the electronic device can configure at least one parameter related to a period during which data transmission and/or reception through the second link is available/possible so that a period for performing data transmission and/or reception through the first link and a period for performing data transmission and/or reception through the second link do not overlap. Accordingly, the electronic device can prevent, or reduce the likelihood of, a situation scheduled to perform data transmission and/or reception through the second link during a time scheduled to perform data transmission and/or reception through the first link, and improve a data transmission and/or reception speed and improve a service quality.

The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a 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). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. 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 subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module  196 .

     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     According to an embodiment, commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the electronic devices  102  or  104  may be a device of a same type as, or a different type, from the electronic device  101 . According to an embodiment, all or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 .

The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 . The electronic device  101  may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

The voice recognition manager  227 , for example, may transmit a user&#39;s voice data to the server  108 , and receive, from the server  108 , a command corresponding to a function to be executed on the electronic device  101  based at least in part on the voice data, or text data converted based at least in part on the voice data. According to an embodiment, the middleware  244  may dynamically delete some existing components or add new components.

       FIG.  3    is a diagram illustrating an electronic device, a first external electronic device, and a second external electronic device according to various example embodiments. 
     With reference to  FIG.  3   , a wireless LAN system  300  shown in  FIG.  3    may include an electronic device  310 , a first external electronic device  320 , and/or a second external electronic device  330 . According to an embodiment, the electronic device  310  may perform wireless communication with the second external electronic device  330  through short-range wireless communication. The short-range wireless communication may refer to a communication technique/method that both the electronic device  310  and/or the second external electronic device  330  can support. For example, wireless communication may be Wi-Fi. The second external electronic device  330  may serve as a base station that provides wireless communication to at least one electronic device (e.g., the electronic device  310 ) positioned inside a communication radius of the wireless LAN system  300 . For example, the second external electronic device  330  may include an access point (AP) of IEEE 802.11. The electronic device  310  may include an IEEE 802.11 station (STA). The electronic device  310  may transmit or receive data to and from the second external electronic device  330  through an STA interface implemented therein. The electronic device  310  may operate in an STA mode while transmitting or receiving data to and from the second external electronic device  330 . 
     Short-range wireless communication used by the electronic device  310  and/or the second external electronic device  330  to exchange data may use various frequency bands including a first frequency band (e.g., 2.4 GHz), a second frequency band (e.g., 5 GHz), and/or a third frequency band (e.g., 6 GHz). The electronic device  310  and/or the second external electronic device  330  may establish a channel included in one frequency band of a plurality of frequency bands and exchange data using the established channel. 
     The electronic device  310  may be connected, directly or indirectly, to the first external electronic device  320  through short-range wireless communication in a state connected, directly or indirectly, to the second external electronic device  330  through short-range wireless communication to transmit data to the first external electronic device  320  or to receive data transmitted by the first external electronic device  320 . 
     The electronic device  310  and the first external electronic device  320  may be directly connected through short-range wireless communication without passing through separate entities (e.g., the second external electronic device  330 ). The electronic device  310  and the first external electronic device  320  may be connected, directly or indirectly, based on a Wi-Fi direct standard defined by Wi-Fi alliance (WFA). 
     In order for the electronic device  310  and/or the first external electronic device  320  to be connected, directly or indirectly, to each other through short-range wireless communication, the electronic device  310  and/or the first external electronic device  320  may perform a discovery operation for discovering an electronic device to be connected, a provisioning discovery exchange operation, a provisioning operation and/or a group owner (GO) negotiation operation for determining an electronic device to be a host among the electronic device  310  and/or the first external electronic device  320 . 
     The electronic device  310  may operate as an AP while transmitting or receiving data to or from the first external electronic device  320  through short-range wireless communication, and the first external electronic device  320  may operate as an STA while transmitting or receiving data to or from the electronic device  310  through short-range wireless communication. The electronic device  310  may transmit or receive data to or from the first external electronic device  320  through a soft AP interface implemented on the electronic device  310  while operating in a software enabled access point (soft AP) mode. The soft AP mode may refer to a mode in which a function of an access point of short-range wireless communication is implemented in software and operate. 
     The electronic device  310  may support various control techniques/methods for controlling a first link  341  between the first external electronic device  320  and the electronic device  310  and a second link  343  between the second external electronic device  330  and the electronic device  310 . The electronic device  310  may control the first link  341  and the second link  343  using one of various control techniques/methods. 
     According to an embodiment, the electronic device  310  may support a function (e.g., real simultaneous dual band (RSDB), dual band simultaneous (DBS)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. In case that the electronic device  310  supports an RSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  310  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  310  may have different frequency bands (or different channel numbers). The electronic device  310  may transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . 
     According to another embodiment, the electronic device  310  may support a function (e.g., virtual simultaneous dual band (VSDB)) capable of performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands at different times. In case that the electronic device  310  supports a VSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  310  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  310  may have different frequency bands (or different channel numbers). However, the electronic device  310  may not transmit or receive data through a second link  343  while transmitting or receiving data through the first link  341 . 
     According to another embodiment, the electronic device  310  may support a function (e.g., single channel concurrent (SCC)) of transmitting or receiving data to and from external electronic devices (e.g., the first external electronic device  320  and/or the second external electronic device  330 ) through the same channel. In case that the electronic device  310  supports SCC, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  310  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  310  may have the same channel number. However, the electronic device  310  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . 
     When the electronic device  310  performs scheduling of an operation of transmitting and/or receiving data through the first link  341  and the second link  343 , the electronic device  310  may support a power management mode and/or a target wake time (TWT). The electronic device  310  may perform different modes for each link. For example, the electronic device  310  may perform scheduling of the first link  341  using the power management mode and perform scheduling of the second link  343  using the TWT. The TWT and power management mode will be described later. 
       FIG.  4 A  is a diagram illustrating an embodiment in which an electronic device controls a communication circuit based on a target wake time (TWT) according to various example embodiments. 
     The electronic device (e.g., the electronic device  310  of  FIG.  3   ) may support a target wake time (TWT) that receives and/or transmits data every designated time and that does not receive and/or transmit data during other times. 
     The TWT is a function proposed and implemented in IEEE 802.11 ax (or Wi-Fi 6), and an electronic device supporting the TWT may transmit and/or receive data through short-range wireless communication during a designated time and switch a communication circuit supporting short-range wireless communication to an idle state (e.g., inactive or doze state) during other time except for the designated time, thereby reducing power consumption in performing short-range wireless communication. 
     The electronic device  310  may activate a TWT function and configure TWT parameters through negotiation with the first external electronic device  320  in a state connected, directly or indirectly, to the first external electronic device  320 . The TWT parameters may be parameters required to perform a TWT function. According to an embodiment, the TWT parameters may include at least one of a target wake time  411  indicating an activation time point of data transmission and/or reception, TWT durations (or TWT service period (SP))  412 - a ,  412 - b , and  412 - c  indicating a period that may perform data transmission and/or reception, and/or TWT wake intervals  413 - a  and  413 - b  indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The first external electronic device  320  may transmit the generated TWT parameter to the electronic device  310  during a negotiation process related to activation of the TWT function. The electronic device  310  may transmit data to the first external electronic device  320  for a specific period (e.g.,  412 - a ,  412 - b , and/or  412 - c ) based on the TWT parameter. 
     The first external electronic device  320  may transmit data to the electronic device  310  for a specific period (e.g.,  412 - a ,  412 - b , and/or  412 - c ). The first external electronic device  320  may activate a communication circuit (e.g., the wireless communication module  192 , comprising communication circuitry, of  FIG.  1   ) for a specific period (e.g.,  412 - a ,  412 - b , and/or  412 - c ), and deactivate the communication circuitry/wireless communication module  192  during another period (e.g.,  414 - a  and/or  414 - b ), thereby reducing power consumption by the communication module including communication circuitry  192 . 
       FIG.  4 B  is a diagram illustrating an embodiment in which an electronic device and a first external electronic device perform a power management mode according to various example embodiments. 
     The electronic device (e.g., the electronic device  310  of  FIG.  3   ) may receive and/or transmit data only in a situation in which there is data to be transmitted or received and support a power management mode that does not receive and/or transmit data during other time. 
     In a power management mode, when the electronic device  310  transmits a signal instructing to transmit and/or receive data based on existence of data to be transmitted or received and receives a response signal corresponding to the signal from the external electronic device (e.g., the second external electronic device  330  of  FIG.  3   ), power consumption in performing wireless communication may be reduced. 
     As the electronic device  310  identifies that data to be transmitted and/or received by the electronic device  310  exists, the electronic device  310  operating in the power management mode may transmit a signal  421  (e.g., Null Data in  FIG.  4 B ) indicating that data to be transmitted and/or received by the electronic device  310  exists to the second external electronic device  330  (e.g., see  FIG.  4 B ). 
     A signal indicating that data to be transmitted or received by the electronic device  310  exists may be implemented in the form of a null data packet (NDP) defined in IEEE 802.11, and the NDP may include a field (e.g., PWR MGT) indicating whether data to be transmitted or received by the electronic device  310  exists. A value (e.g., 0) of a field indicating whether data to be transmitted or received by the electronic device  310  exists in case that data to be transmitted or received by the electronic device  310  exists and a value (e.g., 1) of a field indicating whether data to be transmitted or received by the electronic device  310  exist in case that data to be transmitted or received by the electronic device  310  does not exist may be different from each other. 
     As shown in  FIG.  4 B , the second external electronic device  330  may transmit a response signal  422  corresponding to receiving the signal  421  indicating that data to be transmitted and/or received by the electronic device  310  exists. 
     After receiving the response signal  422  (e.g., ACK), the electronic device  310  that has received the response signal  422  may transmit data  423  to the second external electronic device  330  and/or may receive data  424  transmitted by the second external electronic device  330 . 
     As the electronic device  310  identifies that data to be transmitted or received by the electronic device  310  does not exist, the electronic device  310  may transmit a signal  425  (e.g., Null Data in  FIG.  4 B ) indicating that data to be transmitted or received by the electronic device  310  does not exist to the second external electronic device  330 . The second external electronic device  330  may receive a signal  425  indicating that data to be transmitted or received by the electronic device  310  does not exist and transmit a response signal  426  (e.g., ACK in  FIG.  4 B ). 
     The electronic device  310  may maintain the communication circuit (e.g., the communication circuit  192  of  FIG.  1   ) in an active state only from a time point of transmission of a signal indicating that data to be transmitted or received by the electronic device  310  exist to a time point of reception of a response signal  426  corresponding to a signal  425  indicating that data to be transmitted or received by the electronic device  310  does not exist and deactivate the communication module comprising communication circuitry  192  for other period, thereby reducing power consumption by the communication circuit  192 . 
       FIG.  4 C  is a diagram illustrating an embodiment in which an electronic device and a first external electronic device perform a TWT operation according to various example embodiments. 
     In a state in which the first external electronic device  320  is connected, directly or indirectly, to the electronic device (e.g., the electronic device  310  of  FIG.  3   ) through a first link (e.g., the first link  341  of  FIG.  3   ), the first external electronic device  320  may activate a TWT function and configure TWT parameters through negotiation with the electronic device  310 . In order to activate the TWT function, the first external electronic device  320  may transmit a TWT request message  431  requesting TWT negotiation to the electronic device  310 . The TWT request message  431  may include TWT parameters generated by the first external electronic device  320 . The TWT parameters may be parameters required to perform a TWT function. According to an embodiment, the TWT parameters may include at least one of a target wake time  441  indicating an activation time point of data transmission and/or reception, TWT duration (or TWT service period (SP))  442  indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval  444  indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The electronic device  310  may receive the TWT request message  431 , modify (or maintain) the TWT parameter included in the TWT request message  431 , and transmit a TWT response message  432  including the modified TWT parameter (or the same TWT parameter as that included in the TWT request message  431 ) to the first external electronic device  320 . 
     The first external electronic device  320  may perform a TWT operation based on the TWT parameter included in the TWT response message  432 . 
     The first external electronic device  320  may transmit data to the electronic device  310  for a specific period  442 . The first external electronic device  320  may activate a communication circuit (e.g., the wireless communication module  192 , comprising communication circuitry, of  FIG.  1   ) for a specific period  442 , and deactivate the communication circuit  192  during another period  443 , thereby reducing power consumption by the communication circuit  192 . 
     In a state in which the electronic device  310  is connected, directly or indirectly, to the second external electronic device (e.g., the second external electronic device  330  of  FIG.  3   ) through the second link (e.g., the second link  343  of  FIG.  3   ), the electronic device  310  may activate a TWT function through negotiation with the second external electronic device  330  and configure TWT parameters. The electronic device  310  may operate as an STA while performing short-range wireless communication with the second external electronic device  330 . In order to activate the TWT function, the electronic device  310  may transmit a TWT request message  433  requesting TWT negotiation to the second external electronic device  330 . The TWT request message  433  may include TWT parameters generated by the electronic device  310 . The TWT parameters may be parameters required to perform a TWT function. According to an embodiment, the TWT parameters may include at least one of a target wake time  451  indicating an activation time point of data transmission and/or reception, TWT duration (or TWT service period (SP))  452  indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval  454  indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The second external electronic device  330  may receive the TWT request message  433 , modify (or maintain) the TWT parameter included in the TWT request message  433 , and transmit a TWT response message  434  including the modified TWT parameter (or the same TWT parameter as that included in the TWT request message  433 ) to the electronic device  310 . 
     The electronic device  310  may perform an operation based on the TWT parameter included in the TWT response message. 
     The electronic device  310  may transmit data to the second external electronic device  330  for a specific period  452 . The electronic device  310  may activate a communication circuit (e.g., the wireless communication module  192  of  FIG.  1   ) for a specific period  452 , and deactivate the wireless communication module including wireless communication circuitry  192  during other period  453 , thereby reducing power consumption by the communication circuit  192 . 
     The electronic device  310  may not support simultaneous transmission and/or reception of data through the first link  341  and the second link  343  due to a performance problem thereof. For example, the electronic device  310  may not support an RSDB, but may support a VSDB or SCC. In this case, the electronic device  310  may perform transmission and/or reception of data to and/or from the first external electronic device  320  through the first link  341 , and then perform transmission and/or reception of data to and/or from the second external electronic device  330  through the second link  343 . 
     With reference to  FIG.  4 C  and time  461 , a time  442  at which data transmission and/or reception is performed through the first link  341  and a time (e.g., specific period)  452  at which data transmission and/or reception is performed through the second link  343  is performed may overlap during a partial period  451 . As a length of the partial period  451  increases, a situation in which latency of data transmission and/or reception of the electronic device  310 , the first external electronic device  320 , and/or the second external electronic device  330  increases may occur. 
     Hereinafter, an embodiment of performing scheduling of the first link  341  and/or the second link  343  in order to reduce an overlapping time of a time in which the electronic device  310  transmits and/or receives data through the first link  341  and a time in which the electronic device  310  transmits and/or receives data through the second link  343  will be described. Each embodiment herein may be used in combination with any other embodiment described herein. 
       FIG.  5    is a block diagram illustrating an electronic device according to various example embodiments. 
     According to various example embodiments, an electronic device  500  (e.g., the electronic device  300  of  FIG.  3   ) may include a communication circuit  510  (e.g., the wireless communication module  192  of  FIG.  1   ) and/or a processor  520  (e.g., the processor  120  of  FIG.  1   ). 
     The communication circuit  510  may include various circuit structures used for modulation and/or demodulation of a signal in the electronic device  500 . For example, the communication circuit  510  may modulate a signal of a baseband to a signal of a radio frequency (RF) band so as to output the signal of a baseband through an antenna (not illustrated) or may demodulate a signal of an RF band received through the antenna to the signal of a baseband to transmit the demodulated signal to the processor  520 . 
     The communication circuit  510  may be connected, directly or indirectly, to a first external electronic device (e.g., the first external electronic device  320  of  FIG.  3   ) through the first link (e.g., the first link  341  of  FIG.  3   ) to transmit or receive data. The electronic device  500  may operate as an AP while transmitting or receiving data to and from the first external electronic device  320  through short-range wireless communication, and the first external electronic device  320  may operate as an STA while transmitting or receiving data to or from the electronic device  310  through short-range wireless communication. The electronic device  500  may transmit or receive data to or from the first external electronic device  320  through a soft AP interface implemented on the electronic device  500  while operating in a software enabled access point (soft AP) mode. The soft AP mode may refer to a mode in which a function of an access point of short-range wireless communication is implemented in software and operate. 
     The communication circuit  510  may be connected, directly or indirectly, to the second external electronic device (e.g., the second external electronic device  330  of  FIG.  3   ) through the second link (e.g., the second link  343  of  FIG.  3   ) to transmit or receive data. The electronic device  500  may operate as an STA while transmitting or receiving data to or from the second external electronic device  330  through short-range wireless communication, and the second external electronic device  330  may operate as an AP while transmitting or receiving data to or from the electronic device  500  through short-range wireless communication. 
     The processor  520  may perform an operation of generating a packet for receiving data transmitted by the application processor (e.g., the processor  120  of  FIG.  1   ) and transmitting the received data to the first external electronic device  320 . The processor  520  may be a communication processor (or communication processor) included in a communication module (e.g., the wireless communication module  192  of  FIG.  1   ). Each “module” herein may comprise circuitry. 
       FIG.  5    illustrates that one processor  520  is implemented, but the number of processors  520  may be the plural. In case that the electronic device  500  supports a function (e.g., real simultaneous dual band (RSDB), dual band simultaneous (DBS)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands, the processor  520  may be implemented in the plural. For example, the electronic device  500  may include a first processor (not illustrated) for processing data transmitted or received through the first link (e.g., the first link  341  of  FIG.  3   ) between the first external electronic device (e.g., the first external electronic device  320  of  FIG.  3   ) and the electronic device  500  and a second processor for processing data transmitted or received through the second link (e.g., the second link  343  of  FIG.  3   ) between the second external electronic device (e.g., the second external electronic device  330  of  FIG.  3   ) and the electronic device  500 . Each processor herein comprises processing circuitry. 
     However, in case that the electronic device  500  does not support a function (e.g., real simultaneous dual band (RSDB), dual band simultaneous (DBS)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands, the processor  520  may be implemented as one. The processor  520 , comprising processing circuitry, may control the communication circuit  510  to transmit or receive data through different links according to various techniques/methods (e.g., VSDB and SCC). For example, the processor  520  may control the communication circuit  510  to transmit or receive data through the first link  341  during a first time, and control the communication circuit  510  to transmit or receive data through the second link  343  during a second time. However, it may be recognized that other entities implemented on an upper layer (e.g., framework layer or application layer) of a layer (e.g., hardware layer) that processes data transmission and/or reception support a function in which the electronic device  500  can simultaneously perform transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. 
     According to an embodiment, the processor  520  may generate a packet by performing channel coding based on data transmitted by the application processor (e.g., the application processor  120  of  FIG.  1   ), identify whether there is an error in at least a part of data transmitted by the external electronic device  320 , or in case that an error occurs, the processor  520  may perform an error recovery operation (e.g., automatic repeat request (ARQ) or hybrid automatic repeat request (HARD)). 
     The processor  520  may be operatively connected, directly or indirectly, to the communication circuit  510  to control an operation of the communication circuit  510 . The processor  520  may perform scheduling of data transmission and/or reception through the first link (e.g., the first link  341  of  FIG.  3   ) between the first external electronic device (e.g., the first external electronic device  320  of  FIG.  3   ) and the electronic device  500  and/or the second link (e.g., the second link  343  of  FIG.  3   ) between the second external electronic device (e.g., the second external electronic device  330  of  FIG.  3   ) and the electronic device  500 . Scheduling of the first link  341  and/or the second link  343  may include an operation of determining a time to perform data transmission and/or reception through the first link  341  and/or the second link  343  and/or an operation of determining a time to perform data transmission and/or reception through the second link  343 . 
     The processor  520  may support a target wake time (TWT) function as part of an operation of performing scheduling of the first link  341  and/or the second link  343 . The TWT function may indicate that data transmission and/or reception is performed during a designated time, and that data transmission and/or reception is not performed during an undesignated time. 
     The processor  520  may perform a TWT negotiation with the first external electronic device  320  so as to support a target wake time (TWT) function. The processor  520  may receive TWT parameters generated by the first external electronic device  320  during the TWT negotiation process. Alternatively, the processor  520  may generate TWT parameters to be used by the first external electronic device  320 . 
     According to an embodiment, the processor  520  may generate TWT parameters based on a state of the electronic device  500  and/or a state of the first external electronic device  320 . The state of the electronic device  500  may include at least one of a size of data (or traffic) to be transmitted or received by the electronic device  500 , a quality of service (QoS) requirement, or a contention level of a channel to be created between the electronic device  500  and/or the first external electronic device  320 . The state of the first external electronic device  320  may include at least one of a size of data (or traffic) to be transmitted or received by the first external electronic device  320 , a quality of service (QoS) requirement, or a contention level of a channel to be created between the electronic device  500  and/or the first external electronic device  320 . 
     The processor  520  may receive and/or generate a TWT parameter including at least one of a target wake time (e.g.,  411  of  FIG.  4 A ) indicating an activation time point of data transmission and/or reception, TWT duration (e.g.:  412 - a ,  412 - b , and  412 - c  of  FIG.  4 A ) indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval (e.g.,  413 - a  and  413 - b  of  FIG.  4 A ) indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     For example, the processor  520  may receive and/or generate TWT duration having a relatively large length and/or a TWT wake interval having a relatively small length based on performing a service requiring relatively high-capacity data transmission and relatively low latency. Alternatively, the processor  520  may receive and/or generate TWT duration having a relatively small length and/or a TWT wake interval having a relatively long length based on performing a service that does not require relatively small capacity data transmission and relatively low latency. 
     The processor  520  may perform an operation based on the TWT parameter included in the TWT response message. The processor  520  may control the communication circuit  510  to transmit data to the first external electronic device  320  during TWT durations  442 . The processor  520  may not transmit data to the first external electronic device  320  during communication deactivation periods  443  of the first external electronic device  320 . 
     The processor  520  may perform scheduling of the first link  341  so as to transmit and/or receive data to the first external electronic device  320  during the TWT durations  442 . 
     The processor  520  may support a power management mode (hereinafter, PMM) (or automatic power save delivery (APSD) function) as part of an operation of performing scheduling of the first link  341  and/or the second link  343 . The PMM function or the APSD function may indicate a mode in which the electronic device  500  transmits a signal instructing to perform transmission and/or reception of data based on existence of data to be transmitted or received and in which the electronic device  500  transmits or receives data when receiving a response signal corresponding to the signal from the second external electronic device  330 . The electronic device  500  supporting the power management mode may switch the communication circuit  510  supporting short-range wireless communication to an idle state (e.g., inactive or doze state) in a situation in which data transmission and/or reception is not performed, thereby reducing power consumption in performing short-range wireless communication. 
     The electronic device  500  operating in the power management mode may transmit, to the second electronic device  330 , a signal (e.g.,  421  of  FIG.  4 B ) indicating that data to be transmitted or received by the electronic device  500  exists according to identifying that the electronic device  500  satisfies a designated condition (e.g., a condition in which data to be transmitted or received exists and/or a condition in which the electronic device  500  is switched from an inactive state to an active state). 
     A signal indicating that data to be transmitted or received by the electronic device  500  exists may be implemented in the form of a null data packet (NDP) defined in IEEE 802.11, and the NDP may include a field (e.g., PWR MGT) indicating whether data to be transmitted or received by the electronic device  500  exists. A value (e.g., 0) of a field indicating whether data to be transmitted or received by the electronic device  500  exists in case that data to be transmitted or received by the electronic device  500  exists and a value (e.g., 1) of a field indicating whether data to be transmitted or received by the electronic device  500  exists in case that data to be transmitted or received by the electronic device  500  does not exist may be different from each other. 
     The second external electronic device  330  may transmit a response signal (e.g.,  422  of  FIG.  4 B ) corresponding to receiving the signal  421  indicating that data to be transmitted or received by the electronic device  310  exists. 
     After receiving the response signal  422 , the electronic device  500  that has received the response signal  422  may transmit data (e.g.,  423  of  FIG.  4 B ) to the second external electronic device  330  and/or may receive data (e.g.,  424  of  FIG.  4 B ) transmitted by the second external electronic device  330 . 
     As the electronic device  500  identifies that data to be transmitted or received by the electronic device  500  does not exist, the electronic device  500  may transmit a signal (e.g.,  425  of  FIG.  4 B ) indicating that data to be transmitted or received by the electronic device  500  does not exist to the second external electronic device  330 . The second external electronic device  330  may receive a signal indicating that data to be transmitted or received by the electronic device  500  does not exist and transmit a response signal  426 . 
     The electronic device  500  may perform scheduling of the second link  343  so as to transmit or receive data from a reception time point of the response signal  422  corresponding to the signal  421  indicating that data to be transmitted or received by the electronic device  500  exists to a time point transmitting the signal  425  indicating that data to be transmitted or received by the electronic device  500  does not exist. 
     In the above-described embodiment, it is described that a TWT function is used for performing scheduling of the first link  341  and a PMM (or APSD) function is used for performing scheduling of the second link  343 , but there is no limitation on a function to be used for performing the scheduling of the first link  341  and/or the second link  343 . For example, the electronic device  500  may perform scheduling of the first link  341  using a PMM (or APSD) function and perform scheduling of the second link  343  using a TWT function. As another example, the electronic device  500  may perform scheduling of the first link  341  and/or the second link  343  using the TWT function. As another example, the electronic device  500  may perform scheduling of the first link  341  and/or the second link  343  using a PMM (or APSD) function. 
     The electronic device  500  may not support simultaneous transmission and/or reception of data through the first link  341  and the second link  343  due to a performance problem thereof. For example, the electronic device  500  may not support an RSDB, but may support a VSDB or SCC. In this case, the electronic device  500  may not perform data transmission and/or reception to and/or from the second external electronic device  330  through the second link  343  while performing data transmission and/or reception to and/or from the first external electronic device  320  through the first link  341 . Hereinafter, an embodiment in which scheduling of the first link  341  and/or the second link  343  is performed will be described in consideration of the above problems. 
     The processor  520  may identify a control technique/method of the first link  341  and/or the second link  343 . The control technique/method of the first link  341  and/or the second link  343  may be one of an RSDB, VSDB, and/or SCC. The processor  520  may identify whether the control technique/method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to an embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., real simultaneous dual band (RSDB)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. In case that the electronic device  500  supports an RSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). The electronic device  500  may transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The processor  520  may determine that the control technique/method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, even if the electronic device  500  supports an RSDB, the processor  520  may determine that an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  may not be simultaneously performed corresponding to identifying that a difference between a frequency band of the first link  341  and/or a frequency band of the second link  343  is less than or equal to a designated value. A situation in which the frequency band of the first link  341  and/or the frequency band of the second link  343  is less than or equal to a designated value may indicate a situation in which a signal transmitted or received through the first link  341  acts as interference to interrupt transmission and/or reception of a signal through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., virtual simultaneous dual band (VSDB)) capable of performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands at different times. In case that the electronic device  500  supports the VSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). However, the electronic device  500  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The processor  520 , comprising processing circuitry, may determine that the control technique/method of the first link  341  and/or the second link  343  may not simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., single channel concurrent (SCC)) of transmitting or receiving data to or from external electronic devices (e.g., the first external electronic device  320  and/or the second external electronic device  330 ) through the same channel. In case that the electronic device  500  supports SCC, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have the same channel number. However, the electronic device  310  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The processor  520  may determine that the control technique/method of the first link  341  and/or the second link  343  may not simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     The processor  520  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is available/possible based on at least one parameter related to a period during which data transmission and/or reception through the first link  341  is available/possible corresponding to identifying that the control technique/method of the first link  341  and/or the second link  343  does not simultaneously perform data transmission and/or reception through the first link  341  and the second link  343 . 
     As part of an operation of performing scheduling of data transmission and/or reception through the second link  343 , the processor  520  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is available/possible so that a period during which data transmission and/or reception through the first link  341  is available/possible and a period during which data transmission and/or reception through the second link  343  is available/possible do not overlap (or so that a length of an overlapping period is less than or equal to a designated size). The electronic device  500  does not simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  through the above method, thereby reducing latency of data transmission and/or reception. 
     The parameter related to a period during which data transmission and/or reception through the first link  341  is available/possible may include a TWT parameter in case that the first link  341  performs a TWT. The TWT parameter may include at least one of a target wake time (e.g.,  411  of  FIG.  4 A ) indicating an activation time point of data transmission and/or reception, TWT duration (e.g.,  412 - a ,  412 - b , and  412 - c  of  FIG.  4 A ) indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval (e.g.,  413 - a  and  413 - b  of  FIG.  4 A ) indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The processor  520  may receive a TWT request message transmitted by the first external electronic device  320 , and identify parameters related to a period during which data transmission and/or reception through the first link  341  is available/possible based on the TWT parameter included in the TWT request message. 
     Alternatively, the processor  520  may determine (or generate) TWT parameters based on characteristics of the first link  341  (e.g., a bandwidth of the first link  341 , the number of spatial streams of the first link  341 , and/or an MCS level of data to be transmitted through the first link  341 ) and a size of data to be transmitted through the first link  341  and/or a size of data to be received through the first link  341 . 
     For example, the first external electronic device  320  may be an electronic device (e.g., AR glasses) that receives image data from the electronic device  500  and that displays the image data, and it is assumed that the electronic device  500  transmits one frame during the TWT duration (e.g.,  412 - a ,  412 - b , and  412 - c  of  FIG.  4 A ). The processor  520  may identify characteristics of the first link  341  (e.g., a bandwidth of the first link  341  (e.g., a bandwidth of 160 MHz defined in IEEE 802.11ax), the number (e.g., 2) of streams of the first link  341 , and an MCS level (e.g., MCS  11 ) of the first link  341 ), and determine a network link bandwidth (e.g., 1800 Mbps) of the first link  341  based on the characteristics of the first link  341 . The processor  520  may determine a size (1 ms) of the TWT duration based on a value obtained by dividing a size (e.g., 1.8 Mbits) of data to be transmitted or received through the first link  341  during one TWT duration by the network link bandwidth (e.g., 1800 Mbps) of the first link  341 . The processor  520  may determine the TWT interval (e.g., 45 fps/1 sec=22.2 ms) based on a frame rate (e.g., 45 fps) of the first external electronic device  320 . In addition to the examples described above, the processor  520  may determine TWT parameters based on characteristics of the first link  341  and performance information of the first external electronic device  320  (e.g., a frame rate of the first external electronic device  320 ). 
     In case that the TWT is performed through the first link  341  and the second link  343 , as part of a scheduling operation of the second link  343 , the processor  520  may configure an TWT interval and the TWT duration of the second link  343  so that the TWT duration of the first link  341  and the TWT duration of the second link  343  do not overlap each other (or so that a length of an overlapping period is less than or equal to a designated length). 
     In case that the processor  520  performs a TWT through the first link  341  and operates in a PMM (or APSD) mode through the second link  343 , as part of a scheduling operation of the second link  343 , the processor  520  may control the communication circuit  510  to transmit a signal (e.g.,  421  of  FIG.  4 B ) instructing to perform data transmission and/or reception through the second link  343  so that a period during which data transmission and/or reception through the first link  341  is available/possible and a period during which data transmission and/or reception through the second link  343  is available/possible do not overlap (or so that a length of an overlapping period is equal to or less than a designated size). 
     After the TWT duration of the first link  341  ends, the processor  520  may transmit a signal  421  instructing to perform data transmission and/or reception through the second link  343  to the second external electronic device  330 . As the processor  520  receives a response signal (e.g.,  421  of  FIG.  4 B ) corresponding to the signal  421 , the processor  520  may transmit data to the second external electronic device  330  or may receive data transmitted by the second external electronic device  330  through the second link  343 . The processor  520  may transmit a signal (e.g.,  425  of  FIG.  4 B ) to end data transmission and/or reception through the second link  343  before the next TWT duration of the first link  341  begins, and as the processor  520  receives the response signal (e.g.,  426  of  FIG.  4 B ), the processor  520  may end data transmission and/or reception through the second link  343 . The processor  520  may receive or transmit data from or to the first external electronic device  320  through the first link  341  according to the start of the TWT duration of the first link  341 . Through the above technique/method, it is available/possible to prevent or reduce an increase in latency caused by overlapping times for transmitting or receiving data through the first link  341  and/or the second link  343 . 
     In case that the processor  520  transmits and/or receives data through the second link  343  using an APSD mode, the processor  520  may transmit a signal  421  including information indicating a period during which data transmission and/or reception through the second link  343  is available/possible to the second external electronic device  330 . The signal  421  including information indicating a period during which data transmission and/or reception through the second link  343  is available/possible may be implemented in the form of a trigger frame in the APSD. 
     During the TWT duration of the first link  341 , as the processor  520  identifies that there is no data to be transmitted or received through the first link  341  (or data transmission and/or reception has been completed through the first link  341 ), the processor (e.g., transmits an early termination signal to the first external electronic device  320 )  520  may perform at least one operation for ending a period for performing data transmission and/or reception through the first link  341 , and transmit a signal  421  instructing to perform data transmission and/or reception through the second link  343  to the second external electronic device  330 . As the processor  520  receives a response signal (e.g.,  421  of  FIG.  4 B ) corresponding to the signal  421 , the processor  520  may transmit data to the second external electronic device  330  or may receive data transmitted by the second external electronic device  330  through the second link  343 . 
       FIG.  6    is a diagram illustrating an embodiment in which an electronic device schedules transmission and/or reception of data through a first link and/or a second link while operating in a power management mode according to various example embodiments. 
     The electronic device (e.g., the electronic device  500  of  FIG.  5   ) may identify a control technique/method of a first link (e.g., the first link  341  of  FIG.  3   ) and/or a second link (e.g., the second link  343  of  FIG.  3   ). The control technique/method of the first link  341  and/or the second link  343  may be one of an RSDB, VSDB, and/or SCC. The electronic device  500  may identify whether the control technique/method of the first link  341  and/or the second link  343  may simultaneously perform an operating of transmitting and/or receiving data through the first link  341  and an operating of transmitting and/or receiving data through the second link  343 . 
     According to an embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., real simultaneous dual band (RSDB)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. In case that the electronic device  500  supports an RSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500 . 
     The second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). The electronic device  500  may transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control technique/method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operating of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, even if the electronic device  500  supports an RSDB, the electronic device  500  may determine that an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  may not be simultaneously performed corresponding to identifying that a frequency band of the first link  341  and/or a frequency band of the second link  343  are/is less than or equal to a designated value. A situation in which a frequency band of the first link  341  and/or a frequency band of the second link  343  are/is less than or equal to a designated value may indicate a situation in which a signal transmitted or received through the first link  341  acts as interference to interrupt transmission and/or reception of a signal through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., virtual simultaneous dual band (VSDB)) capable of performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands at different times. In case that the electronic device  500  supports the VSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  the electronic device  500  may have different frequency bands (or different channel numbers). However, the electronic device  500  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control technique/method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., single channel concurrent (SCC)) of transmitting or receiving data to or from external electronic devices (e.g., the first external electronic device  320  and/or the second external electronic device  330 ) through the same channel. In case that the electronic device  500  supports SCC, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have the same channel number. However, the electronic device (e.g.,  310 ) may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control technique/method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     The electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is available/possible based on at least one parameter related to a period during which data transmission and/or reception through the first link  341  is available/possible corresponding to identifying that the control technique/method of the first link  341  and/or the second link  343  does not simultaneously perform data transmission and/or reception data through the first link  341  and the second link  343 . 
     The parameter related to a period during which data transmission and/or reception through the first link  341  is available/possible may include a TWT parameter in case that the first link  341  performs a TWT.

     In case that the electronic device  500  performs a TWT through the first link  341  and the second link  343 , as part of a scheduling operation of the second link  343 , the electronic device  500  may configure a target wake time  811  so that the target wake time  811  of the second link  343  does not occur within the TWT durations  804  and  807  of the first link  341 .

With reference to  FIG.  8   , it may be identified that the TWT duration  812  of the second link  343  does not overlap the TWT duration  804  of the first link  341 . 
     The electronic device  500  may transmit or receive data to or from the first external electronic device  320  through the first link  341  during the TWT duration  807  of the first link  341  started after the TWT duration  812  of the second link  343  ends.

       FIG.  9    is a flowchart illustrating a method  900  of operating an electronic device according to various example embodiments. 
     In operation  910 , the electronic device (e.g., the electronic device  500  of  FIG.  5   ) may identify a control method of the first link (e.g., the first link  341  of  FIG.  3   ) and/or the second link (e.g., the second link  343  of  FIG.  3   ). 
     The control method of the first link  341  and/or the second link  343  may be one of an RSDB, VSDB, and/or SCC. The electronic device  500  may identify whether the control method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to an embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., real simultaneous dual band (RSDB)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. In case that the electronic device  500  supports an RSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). The electronic device  500  may transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, even if the electronic device  500  supports an RSDB, the electronic device  500  may determine that an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  may not be simultaneously performed corresponding to identifying that a frequency band of the first link  341  and/or a frequency band of the second link  343  are/is less than or equal to a designated value. A situation in which the frequency band of the first link  341  and/or the frequency band of the second link  343  are/is less than or equal to a designated value may indicate a situation in which a signal transmitted or received through the first link  341  acts as interference to interrupt transmission and/or reception of a signal through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., virtual simultaneous dual band (VSDB)) capable of performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands at different times. In case that the electronic device  500  supports the VSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). However, the electronic device  500  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., single channel concurrent (SCC)) of transmitting or receiving data to and from external electronic devices (e.g., the first external electronic device  320  and/or the second external electronic device  330 ) through the same channel. In case that the electronic device  500  supports SCC, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have the same channel number. However, the electronic device  310  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     In operation  920 , the electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is possible based on at least one parameter related to a period during which data transmission and/or reception through the first link  341  is possible corresponding to identifying that the control method of the first link  341  and/or the second link  343  does not perform simultaneously data transmission and/or reception through the first link  341  and the second link  343 . 
     As part of an operation of scheduling data transmission and/or reception through the second link  343 , the electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is possible so that a period during which data transmission and/or reception through the first link  341  is possible and a period during which data transmission and/or reception through the second link  343  is possible do not overlap (or so that a length of an overlapping period is less than or equal to a designated size). The electronic device  500  does not simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  through the above method, thereby reducing latency of data transmission and/or reception. 
     The parameter related to a period during which data transmission and/or reception through the first link  341  is possible may include a TWT parameter in case that the first link  341  performs a TWT. The TWT parameter may include at least one of a target wake time (e.g.,  411  of  FIG.  4 A ) indicating an activation time point of data transmission and/or reception, TWT duration (e.g.,  412 - a ,  412 - b , and  412 - c  of  FIG.  4 A ) indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval (e.g.,  413 - a  and  413 - b  of  FIG.  4 A ) indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The electronic device  500  may receive a TWT request message transmitted by the first external electronic device  320 , and identify parameters related to a period during which data transmission and/or reception through the first link  341  is possible based on the TWT parameter included in the TWT request message. 
     Alternatively, the electronic device  500  may determine (or generate) the TWT parameter based on characteristics of the first link  341  (e.g., a bandwidth of the first link  341 , the number of spatial streams of the first link  341 , and/or an MCS level of data to be transmitted through the first link  341 ), a size of data to be transmitted through the first link  341 , and a size of data to be received through the first link  341 . 
     In case that the electronic device  500  performs a TWT through the first link  341  and the second link  343 , as part of a scheduling operation of the second link  343 , the electronic device  500  may configure TWT duration and a TWT interval of the second link  343  so that TWT duration of the first link  341  and TWT duration of the second link  343  do not overlap each other (or so that a length of an overlapping period is less than or equal to a designated length). 
     In case that the electronic device  500  performs a TWT through the first link  341  and operates in a PMM (or APSD) mode through the second link  343 , as part of a scheduling operation of the second link  343 , the electronic device  500  may control the communication circuit  510  to transmit a signal (e.g.,  421  of  FIG.  4 B ) instructing to perform data transmission and/or reception through the second link  343  so that a period during which data transmission and/or reception through the first link  341  is possible and a period during which data transmission and/or reception through the second link  343  is possible do not overlap (or so that a length of an overlapping period is less than or equal to a designated length). 
     After the TWT duration of the first link  341  ends, the electronic device  500  may transmit a signal  421  instructing to perform data transmission and/or reception through the second link  343  to the second external electronic device  330 . As the electronic device  500  receives a response signal (e.g.,  421  of  FIG.  4 B ) corresponding to the signal  421 , the electronic device  500  may transmit data to the second external electronic device  330  or may receive data transmitted by the second external electronic device  330  through the second link  343 . Before next TWT duration of the first link  341  begins, as the electronic device  500  transmits a signal (e.g.,  425  of  FIG.  4 B ) ending data transmission and/or reception through the second link  343  and receives a response signal (e.g.,  426  of  FIG.  4 B ), the electronic device  500  may end data transmission and/or reception through the second link  343 . The electronic device  500  may receive or transmit data from or to the first external electronic device  320  through the first link  341  according to the start of TWT duration of the first link  341 . Through the above method, it is possible to prevent or reduce an increase in latency caused by overlapping times for transmitting or receiving data through the first link  341  and/or the second link  343 . 
       FIG.  10    is a flowchart illustrating a method  900  of operating an electronic device according to various example embodiments. 
     In operation  1010 , the electronic device (e.g., the electronic device  500  of  FIG.  5   ) may identify a control method of a first link (e.g., the first link  341  of  FIG.  3   ) and/or a second link (e.g., the second link  343  of  FIG.  3   ). 
     The control method of the first link  341  and/or the second link  343  may be one method of an RSDB, VSDB, and/or SCC. 
     In operation  1020 , the electronic device  500  may identify whether performing an operation of transmitting and/or receiving data through the first link  341  and the second link  343 . 
     The electronic device  500  may identify whether the control method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to an embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., real simultaneous dual band (RSDB)) capable of simultaneously performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands. In case that the electronic device  500  supports an RSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). The electronic device  500  may transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, even if the electronic device  500  supports an RSDB, the electronic device  500  may determine that an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  may not be simultaneously performed corresponding to identifying that a frequency band of the first link  341  and/or a frequency band of the second link  343  are/is less than or equal to a designated value. A situation in which a frequency band of the first link  341  and/or a frequency band of the second link  343  are/is less than or equal to a designated value may indicate a situation in which a signal transmitted or received through the first link  341  acts as interference to interrupt transmission and/or reception of a signal through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., virtual simultaneous dual band (VSDB)) capable of performing transmission and/or reception of signals through at least two frequency bands of a plurality of frequency bands at different times. In case that the electronic device  500  supports the VSDB, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have different frequency bands (or different channel numbers). However, the electronic device  500  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     According to another embodiment, the electronic device  500  may control the first link  341  and/or the second link  343  using a function (e.g., single channel concurrent (SCC)) of transmitting or receiving data to or from external electronic devices (e.g., the first external electronic device  320  and/or the second external electronic device  330 ) through the same channel. In case that the electronic device  500  supports SCC, the first link  341  used for data exchange between the first external electronic device  320  and the electronic device  500  and the second link  343  used for data exchange between the second external electronic device  330  and the electronic device  500  may have the same channel number. However, the electronic device  310  may not transmit or receive data through the second link  343  while transmitting or receiving data through the first link  341 . The electronic device  500  may determine that the control method of the first link  341  and/or the second link  343  may not perform simultaneously an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343 . 
     In operation  1030 , the electronic device  500  may identify whether a difference between the frequency band of the first link  341  and the frequency band of the second link  343  is less than or equal to a designated value corresponding to identifying (operation  1020 -Y) that the control method of the first link  341  and/or the second link  343  may perform simultaneously data transmission and/or reception through the first link  341  and the second link  343 . 
     The electronic device  500  may determine that an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  may not be simultaneously performed corresponding to identifying that a difference between the frequency band of the first link  341  and/or the frequency band of the second link  343  is less than or equal to a designated value (operation  1030 -Y). A situation in which the frequency band of the first link  341  and/or the frequency band of the second link  343  are/is less than or equal to a designated value may indicate a situation in which a signal transmitted or received through the first link  341  acts as interference to interrupt transmission and/or reception of a signal through the second link  343 . 
     In operation  1040 , the electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is possible based on at least one parameter related to a period during which data transmission and/or reception through the first link  341  is possible corresponding to identifying that a difference between the frequency band of the first link  341  and/or the frequency band of the second link  343  is less than or equal to a designated value (operation  1030 -Y). 
     As part of an operation of scheduling data transmission and/or reception through the second link  343 , the electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is possible so that a period during which data transmission and/or reception through the first link  341  is possible and a period during which data transmission and/or reception through the second link  343  is possible do not overlap (or so that a length of an overlapping period is less than or equal to a designated size). The electronic device  500  does not simultaneously perform an operation of transmitting and/or receiving data through the first link  341  and an operation of transmitting and/or receiving data through the second link  343  through the above method, thereby reducing latency of data transmission and/or reception. 
     In operation  1050 , the electronic device  500  may identify whether a TWT is performed through the second link  343  corresponding to identifying that the control method of the first link  341  and/or the second link  343  does not perform simultaneously data transmission and/or reception through the first link  341  and the second link  343  (operation  1020 -N). 
     A parameter related to a period during which data transmission and/or reception through the first link  341  is possible may include a TWT parameter in case that the first link  341  performs a TWT. The TWT parameter may include at least one of a target wake time (e.g.,  411  of  FIG.  4 A ) indicating an activation time point of data transmission and/or reception, TWT duration (e.g.,  412 - a ,  412 - b , and  412 - c  of  FIG.  4 A ) indicating a period that may perform data transmission and/or reception, and/or a TWT wake interval (e.g.,  413 - a  and  413 - b  of  FIG.  4 A ) indicating an interval between an activation time point of data transmission and/or reception and a next activation time point of data transmission and/or reception. 
     The electronic device  500  may receive a TWT request message transmitted by the first external electronic device  320  and identify parameters related to a period during which data transmission and/or reception through the first link  341  is possible based on the TWT parameter included in the TWT request message.

     As part of a scheduling operation of the second link  343 , the electronic device  500  may configure TWT duration and a TWT interval of the second link  343  so that TWT duration of the first link  341  and TWT duration of the second link  343  do not overlap each other (or so that a length of an overlapping period is less than or equal to a designated length). 
     In operation  1060 , the electronic device  500  may identify whether the electronic device  500  operates in a PMM or APSD mode through the second link  343  corresponding to identifying that the electronic device  500  does not perform a TWT through the second link  343  (operation  1050 -N). 
     In operation  1040 , the electronic device  500  may configure at least one parameter related to a period during which data transmission and/or reception through the second link  343  is possible based on at least one parameter related to a period during which data transmission and/or reception through the first link  341  is possible corresponding to identifying that a PMM or APSD mode is performed through the second link  343  (operation  1060 -Y).
