[0001] Embodiments disclosed in this document relate to an electronic device supporting reference signal transmission and a method for controlling the electronic device.

[0002] In mobile communications, a user device can communicate with a base station using wireless signals. For wireless communications, the user device and / or the base station can perform channel measurements and / or estimation. For example, the user device can measure and / or estimate the status of a downlink channel by receiving a reference signal from the base station. The user device can transmit information about the status of the downlink channel to the base station. The base station can perform scheduling for the user device using the received information about the status of the downlink channel. For example, the base station can measure and / or estimate the status of an uplink channel by receiving a reference signal from the user device. The base station can perform scheduling for the user device based on the status of the uplink channel. If the uplink channel and the downlink channel have channel reciprocity, the base station can identify and / or estimate the status of the downlink channel based on the status of the uplink channel.

[0003] The base station can perform scheduling based on the status of the channel associated with the user device. For example, the base station can allocate uplink and / or downlink radio resources associated with the user device to the user device based on the channel status. For example, by performing communications based on the status of the channel associated with the user device, the base station can efficiently allocate radio resources and increase the throughput of the user device.

[0034] In one embodiment, the electronic device (10) may be configured to transmit a reference signal (e.g., SRS) to the first base station (20) or the second base station (30). For example, the first base station (20) may need to measure channel information associated with the electronic device (10) in order to allocate radio resources to the electronic device (10). For example, the first base station (20) may transmit radio resource information for transmitting the reference signal to the electronic device (10) (e.g., via RRC (radio resource control) signaling). The electronic device (10) may transmit the reference signal to the first base station (20) based on the received radio resource information. The first base station (10) may estimate the quality of an uplink channel of the electronic device (10) using the reference signal received from the electronic device (10). The first base station (10) may perform radio resource allocation for the electronic device (10) based on the estimated channel quality. In one example, when the electronic device (10) uses a wireless resource based on time division duplex, the first base station (10) can also estimate the quality of the downlink channel from the reference signal based on channel reciprocity.

[0035] According to one embodiment, the electronic device (10) may support antenna switching for transmitting a reference signal. For example, the electronic device (10) may include more antennas than the number of transmission ports. In this case, the electronic device (10) may transmit a reference signal through multiple antennas while switching the antennas connected to the transmission ports. For example, the first base station (10) may obtain channel information associated with multiple antennas of the electronic device (10) by receiving reference signals through various antennas. The first base station (10) may control the wireless connection of the electronic device (10) using the channel information. For example, the first base station (10) may set carrier aggregation (CA) to the electronic device (10) based on the channel information.

[0036] The communication system (100) associated with the electronic device (10) described above with reference to FIG. 1 is exemplary, and embodiments of the present disclosure are not limited thereto. For example, the communication system (100) of embodiments of the present disclosure may include any system utilizing an uplink reference signal. The network environment illustrated in FIG. 1 is an example, and at least one base station and / or at least one cell may be omitted from the communication system (100).

[0037] FIG. 2 illustrates wireless communication systems providing networks of legacy communications and / or 5G communications according to various embodiments.

[0038] Referring to FIG. 2, the network environments (200a, 200b, and 200c) may include at least one of a legacy network and a 5G network. The legacy network may include, for example, a 4G or LTE base station (240) (e.g., an eNodeB (eNB)) of a 3rd generation partnership project (3GPP) standard that supports wireless connection with an electronic device (10) and an evolved packet core (EPC) (242) that manages 4G communication. The 5G network may include, for example, a New Radio (NR) base station (250) (e.g., a gNodeB (gNB)) that supports wireless connection with an electronic device (10) and a 5GC (252) (5th generation core) that manages 5G communication of the electronic device (10).

[0039] According to one embodiment, the electronic device (10) may transmit and receive control messages and user data via legacy communication and / or 5G communication. The control messages may include, for example, messages related to at least one of security control, bearer setup, authentication, registration, or mobility management of the electronic device (10). The user data may refer to, for example, user data excluding control messages transmitted and received between the electronic device (10) and the core network (230) (e.g., EPC (242)).

[0040] According to one embodiment, the electronic device (10) can support dual connectivity (e.g., Multi-RAT (MR)-Dual Connectivity (DC)) using different Radio Access Technologies (RATs). For example, the electronic device (10) can transmit and receive at least one of a control message or user data with at least a part of a 5G network (e.g., an NR base station (250) or 5GC (252)) using at least a part of a legacy network (e.g., an LTE base station (240) or EPC (242)).

[0041] According to one embodiment, the electronic device (10) can perform carrier aggregation. For example, the electronic device (10) can perform carrier aggregation by utilizing a plurality of component carriers associated with a legacy network or a 5G network.

[0042] Referring to reference number 200a, in an MR-DC environment, one of the LTE base stations (240) or the NR base station (250) may operate as a master node (MN) (210) and the other may operate as a secondary node (SN) (220). The MN (210) may be connected to a core network (230) and may transmit and receive control messages. The MN (210) and the SN (220) may be connected via a network interface and may transmit and receive messages related to management of radio resources (e.g., communication channels) to each other.

[0043] In one embodiment, the MN (210) may include an LTE base station (250), the SN (220) may include an NR base station (250), and the core network (230) may include an EPC (242).

In another example, the electronic device (10) and the 5GC (252) can transmit and receive control messages and user data via the NR base station (250).

[0046] According to one embodiment, the electronic device (10) can be registered with at least one of the EPC (242) or the 5GC (252) to transmit and receive control messages.

[0047] According to various embodiments, the EPC (242) or the 5GC (252) may interwork to manage communication of the electronic device (10). For example, movement information of the electronic device (10) may be transmitted and received through an interface between the EPC (242) and the 5GC (252).

[0048] FIG. 3 illustrates a block diagram of an electronic device according to one embodiment.

[0049] According to one embodiment, the electronic device (10) may include a processor (120), a memory (130), an antenna module (170), and / or a communication module (190). For example, the electronic device (10) may correspond to the electronic device (1201) of FIG. 12. The structure of the electronic device (10) illustrated in FIG. 3 is exemplary, and the embodiments of the present document are not limited thereto. For example, the electronic device (10) may further include a configuration not illustrated in FIG. 3 (e.g., the configuration of the electronic device (1201) of FIG. 12).

[0050] The processor (120) may include at least one processing circuit and / or at least one processor. The processor (120) may include at least one of a central processing unit (CPU), a micro processing unit (MPU), an application processor (AP), a modem, a communication processor (CP), a system on chip (SoC), or an integrated circuit (IC). In one example, the processor (120) may be implemented as a chipset. The processor (120) may include one processor or multiple processors. For example, the processor (120) may correspond to the processor (1201) of FIG. 12 .

[0051] The processor (120) can control the electronic device (10) to perform various operations by executing instructions stored in the memory (130). The processor (120) can control various components of the electronic device (10) to perform various operations. For example, the operations of the electronic device (10) described below can be referred to as being performed by the processor (120). The processor (120) can cause the electronic device (10) to perform various operations by executing one or more instructions stored in the memory (130). When the processor (120) includes a plurality of processors, at least some of the operations of the electronic device (10) can be performed by a first processor among the plurality of processors, and at least some of the operations of the electronic device (10) can be performed by a second processor among the plurality of processors.

[0052] The processor (120) may include a baseband processor that processes a baseband signal received from the communication module (190) or transmits a baseband signal to the communication module (190). The processor (120) may be electrically, operatively, or functionally connected to the memory (130), the antenna module (170), the sensor circuit (180), and / or the communication module (190). In the present disclosure, when a component is “operatively” connected to another component, it may mean that the component is connected so as to be able to operate the other component. For example, the component may operate the other component by transmitting a control signal to the other component, either directly or via another component. In the present disclosure, when a component is “functionally” connected to another component, it may mean that the component is connected so as to be able to execute a function of the other component. For example, the component may execute a function of the other component by transmitting a control signal to the other component, either directly or via another component.

[0053] For example, the memory (130) may be implemented as a single chip or chipset with the processor (120). For example, the memory (130) may be implemented as a separate chip from the processor (120). In one example, the memory (130) may correspond to the memory (1230) of FIG. 12. The memory (130) may be composed of a single memory chip or a plurality of memory chips. The memory (130) may store data (e.g., instructions) that may be processed by the processor (120).

[0054] For example, the antenna module (170) may include a plurality of antennas. The antenna module (170) may include a plurality of radiators that may be used as antennas. For example, at least some of the plurality of antennas may include a portion of the housing of the electronic device (10) (e.g., a portion of a side member), a metallic pattern, a metallic radiator, and / or a conductive member. Examples of antennas may be described below with reference to FIG. 5. The antenna module (170) may include a tuning circuit for tuning the antenna. In one example, the antenna module (170) may correspond to the antenna module (1297) of FIG. 12.

[0055] The communication module (190) may include at least one circuit for transmitting and receiving wireless signals. For example, the communication module (190) may correspond to the wireless communication module (1292) of FIG. 12. The communication module (190) may receive a signal using the antenna module (170). The communication module (190) may convert a signal received using the antenna module (170) into a baseband signal and transmit the converted signal to the processor (120). For example, the communication module (190) may transmit a signal using the antenna module (170). The communication module (190) may convert a baseband signal received from the processor (120) into a radio frequency signal and transmit the converted radio frequency signal through the antenna module (170). The processor (120) may transmit and receive a radio signal by controlling the communication module (190). Examples of the communication module (190) may be described below with reference to FIGS. 4 to 10. The communication module (190) may be composed of one or more chips. The communication module (190) may also include any circuit components for signal processing (e.g., a diplexer, a duplexer, a switching circuit, a filter, an amplifier, and / or a phase shifter).

[0056] According to one embodiment, the electronic device (10) can transmit a reference signal to a connected (e.g., RRC-connected) base station. For example, the electronic device (10) can transmit a sounding reference signal (SRS) to enable the base station to identify and / or estimate electric field and channel conditions. The base station can receive the SRS and, by measuring the received SRS, identify and / or estimate electric field and channel conditions associated with the electronic device (10).

[0057] For example, the electronic device (10) can transmit an SRS using multiple antennas. The electronic device (10) can transmit the SRS through the multiple antennas by switching the transmission antennas. Transmission of the SRS using the switching of the transmission antennas can be referred to as sounding reference signal transmit antenna switching (SRS TAS). For example, by receiving the SRSs transmitted through the multiple antennas, the base station can perform optimized beamforming for the electronic device (10). Through the optimized beamforming, the throughput of the electronic device (10) can be increased. The electronic device (10) can receive a signal from the base station that instructs transmission of the multiple SRSs. For example, by receiving radio resource control (RRC) signaling from the base station that instructs transmission of the SRSs, the electronic device (10) can transmit the multiple SRSs. The electronic device (10) can transmit the multiple SRSs using the radio resources indicated by the RRC signaling.

[0058] In one example, the electronic device (10) may transmit multiple SRSs based on antenna switching. For example, the electronic device (10) may transmit a first SRS using a first antenna and a second SRS using a second antenna. For antenna switching, at least one switch may be connected between the antenna and a communication circuit (e.g., a transceiver). In this case, insertion loss may occur due to the insertion of the switch. For example, an insertion loss of about 0.5 dB to 0.6 dB may occur compared to a case where the switch is not present. In this case, the quality of the uplink signal of the electronic device (10) may be reduced. In order to compensate for the insertion loss, if the transmission power of the uplink signal is increased, the power consumption of the electronic device (10) may increase.

[0059] According to one embodiment, the electronic device (10) can support antenna switching for transmitting a reference signal and reduce insertion loss due to the switch. For example, the communication module (190) of the electronic device (10) can include at least one bypass path. By transmitting a wireless signal through the bypass path, the quality of the uplink signal of the electronic device (10) can be improved and power consumption can be reduced. Hereinafter, various structures of the electronic device (10) are described with reference to FIGS. 4 to 10 . The examples of FIGS. 4 to 10 are one example of the communication module (190) of the electronic device (10), and the embodiments of the present disclosure are not limited thereto.

For example, the first communication circuit (190a) may include a transmit path (600), a first receive path (601), a second receive path (602), and a third receive path (603). The number of receive paths and the number of transmit paths illustrated in FIG. 6 are examples, and embodiments of the present disclosure are not limited thereto. For example, if the transceiver (190c) includes multiple transmit ports, the first communication circuit (190a) may include multiple transmit paths.

[0075] In one example, the transmit path (600) may include at least one power amplifier (e.g., power amplifier (610)) and / or a filter circuit (620). In one example, the transmit path (600) may be coupled to a feedback path (not shown) via a coupler. For example, the first receive path (601) may include at least one power amplifier (e.g., low noise amplifier, LNA) (e.g., first power amplifier (611)) and / or a first filter circuit (621). For example, the second receive path (602) may include at least one power amplifier (e.g., second power amplifier (612)) and / or a second filter circuit (622). For example, the third receive path (603) may include at least one power amplifier (e.g., third power amplifier (613)) and / or a third filter circuit (623).

[0076] The first communication circuit (190a) may include a switching circuit (630). For example, the switching circuit (630) may include a diplexer, at least one switch, and / or at least one duplexer. The switching circuit (630) may be configured to change the connection between the receive path and the transmit path and the first antenna circuit (170a). For example, the switching circuit (630) may be configured to receive a control signal from a transceiver (190c) or a processor (e.g., the processor (120) of FIG. 4) and change the connection between the first communication circuit (190a) and the first antenna circuit (170a) based on the received control signal.

[0077] According to one embodiment, the switching circuit (630) may include at least one bypass path. The bypass path may be referred to as an electrical path between the antenna and the transceiver (190c) that does not pass through a switch that supports antenna switching. In one example, the electronic device (10) may transmit the data signal through the bypass path when transmitting the data signal. In the present disclosure, the data signal may be referred to as an uplink signal that does not include a designated reference signal (e.g., SRS). For example, even if the uplink signal includes a reference signal, if the reference signal is not a designated reference signal, it may be included in the data signal of the present disclosure.

[0078] According to one embodiment, the switching circuit (630) may include at least one switch. For example, the switching circuit (630) may electrically connect the antennas to a reference signal generator for transmitting a reference signal. For example, if a reference signal generator (e.g., a wireless communication circuit configured to generate an SRS) is included in the transceiver (190c) or the first communication circuit (190a), the electronic device (10) may use the switching circuit (630) to electrically connect one of the antennas to the reference signal generator. In one example, if the reference signal generator is not included in the transceiver (190c) or the first communication circuit (190a), the switching circuit (630) may include a switch electrically connected to an external reference signal generator.

[0079] For example, the first antenna circuit (170a) may include a first antenna (651), a second antenna (652), and / or a third antenna (653). The first antenna (651) may be electrically connected to a first tuning circuit (641). The first tuning circuit (641) may include at least one element and / or switch for impedance control of the first antenna (651). For example, the second antenna (652) may be electrically connected to the second tuning circuit (642), and the third antenna (653) may be electrically connected to the third tuning circuit (643). The tuning circuit illustrated in FIG. 6 is an example, and at least some of the illustrated tuning circuits may be omitted.

[0080] For convenience of explanation, the first communication circuit (190a) and the first antenna circuit (170a) have been described with reference to FIG. 6, but similar structures may also be applied to the second communication circuit (190b) and the second antenna circuit (170a) of FIG. 4. For example, the second communication circuit (190b) may include a structure similar to the first communication circuit (190a). For example, the second antenna circuit (170b) may include a structure similar to the first antenna circuit (170a). In one example, the switching circuit (630) may be configured so that the first communication circuit (190a) and the second communication circuit (190b) can share at least one antenna.

[0081] Hereinafter, various operations and structures of an electronic device (10) according to an embodiment may be described with reference to FIGS. 7A to 10. Hereinafter, various operations of the electronic device (10) are described with reference to the contents described above with reference to FIGS. 1 to 6. However, the above description with reference to FIGS. 1 to 6 is intended to aid understanding and is not intended to limit the scope of the present disclosure.

[0082] FIG. 7A illustrates a connection setup for data transmission via a first antenna of an electronic device according to one embodiment.

[0083] Referring to FIGS. 3 and 7A, according to one embodiment, the first communication circuit (190a) may include at least a portion of the first electrical path (701). For example, the first electrical path (701) may correspond to the transmission path (600) of FIG. 6. The first electrical path (701) is an electrical path between the transceiver (190c) and the first antenna (651), and may be referred to as a bypass path. As described below, the electronic device (10) may transmit a data signal through the switching circuit (731) via the first electrical path (701).

[0084] In one example, a power amplifier (610), a filter circuit (721), a coupler (722), and / or a first tuning circuit (641) may be electrically connected to the first electrical path (701). The filter circuit (721) may include a bandpass filter, a lowpass filter, and / or a highpass filter configured to filter a signal transmitted from the transceiver (190c). The transceiver (190c) may receive at least a portion of the transmitted signal via a feedback path (not shown) electrically connected to the coupler (722). The first tuning circuit (641) may be configured to perform impedance control of the first antenna (651) and / or the first electrical path (701). The configuration of the first electrical path (701) illustrated in FIG. 7A is an example, and embodiments of the present disclosure are not limited thereto. For example, the coupler (722) may be omitted from the first electrical path (701). For example, a duplexer may be positioned in the first electrical path (701) to share the first antenna (651) with the receiving path.

[0085] According to one embodiment, the first tuning circuit (641) may be configured to connect at least one of a plurality of impedance values ​​to the first electrical path (701). The first tuning circuit (641) may be configured to control the first switch (741) based on a signal received from the first wireless communication circuit (190a), the transceiver (190c), or the processor (e.g., the processor of the electronic device (10)). The first switch (741) may be configured to selectively connect one of the preset impedances to the second point (P2), for example. The first switch (741) may be configured to connect the first impedance (Z0), the second impedance (Z1), or the third impedance (Z2) to the second point (P2). The configuration of the first tuning circuit (641) illustrated in FIG. 7A is merely an example, and embodiments of the present disclosure are not limited thereto. For example, the number of impedances for which the first tuning circuit (641) can be set is not limited to three.

[0086] The first tuning circuit (641) may be electrically connected to a second point (P2) between the first antenna (651) of the first electrical path (701) and the first point (P1). The first tuning circuit (641) may be electrically connected to a third electrical path (703) branched from the second point (P2). The first tuning circuit (641) may be included in the first antenna circuit (170a) or implemented in a separate configuration from the first antenna circuit (170a).

[0087] In one example, a switching circuit (731) (e.g., a switching circuit (630) of FIG. 6) may be connected to a first electrical path (701) via a second electrical path (702). The second electrical path (702) may be electrically connected between the first electrical path (701) and the switching circuit (731). For example, the second electrical path (702) may branch out from a first point (P1) of the first electrical path (701) and be electrically connected to the switching circuit (731). The switching circuit (731) may be configured to electrically connect the first point (P1) to a fourth electrical path (704), a fifth electrical path (705), or a designated impedance (Z). For example, the processor (120) of the electronic device (10) may control the switching circuit (731) directly or through another configuration (e.g., a transceiver (190c) and / or a first communication circuit (190a)). In one example, the switching circuit (731) may include a single-pole multi-throw (SPMT) switch.

[0088] The fourth electrical path (704) may be referred to as an electrical path between the switching circuit (731) and the second antenna (652). A second tuning circuit (642) may be connected to a third location (P3) of the fourth electrical path (704). For example, the second tuning circuit (642) may be connected to an electrical path branched from the third location (P3). The second tuning circuit (642) may be configured to connect at least one of a plurality of impedance values ​​to the fourth electrical path (704). The second tuning circuit (642) may be configured to control the second switch (742) based on a signal received from the first wireless communication circuit (190a), the transceiver (190c), or the processor (120). The second switch (742) may be configured to selectively connect one of the preset impedances to the third point (P3), for example. The second switch (742) may be configured to connect the first impedance (Z0), the second impedance (Z1), or the third impedance (Z2) to the third point (P3). The configuration of the second tuning circuit (642) illustrated in FIG. 7A is an example, and the embodiments of the present disclosure are not limited thereto. For example, the number of impedances to which the second tuning circuit (642) may be configured is not limited to three.

[0089] The fifth electrical path (705) may be referred to as an electrical path between the switching circuit (731) and the third antenna (653). A third tuning circuit (643) may be connected to a fourth location (P4) of the fifth electrical path (705). For example, the third tuning circuit (643) may be connected to an electrical path branched from the fourth location (P4). The third tuning circuit (643) may be configured to connect at least one of a plurality of impedance values ​​to the fifth electrical path (705). The third tuning circuit (643) may be configured to control the third switch (743) based on a signal received from the first wireless communication circuit (190a), the transceiver (190c), or the processor (120). The third switch (743) may be configured to selectively connect, for example, one of the preset impedances to the fourth point (P4). The third switch (743) may be configured to connect the first impedance (Z0), the second impedance (Z1), or the third impedance (Z2) to the fourth point (P4). The configuration of the third tuning circuit (643) illustrated in FIG. 7A is an example, and the embodiments of the present disclosure are not limited thereto. For example, the number of impedances to which the fourth tuning circuit (643) may be configured is not limited to three.

[0090] According to one embodiment, the electronic device (10) may control the switching circuit (731) to bring the second electrical path (702) into a substantially open state based on transmission of a data signal (e.g., an uplink signal not including an SRS) through the first antenna (651). The electronic device (10) may control the switching circuit (731) to bring the second electrical path (702) into a substantially open state when transmission of a data signal is scheduled (e.g., when transmission of an uplink signal is scheduled) or when transmission of a designated reference signal (e.g., an SRS) is not imminent (e.g., when transmission of an SRS is not scheduled within a designated time). The electronic device (10) may control the switching circuit (731) to bring the second electrical path (702) into a substantially open state, and may control the switching circuit (731) as described below with respect to FIGS. 7b to 7d based on transmission of a designated reference signal (e.g., an SRS) through antenna switching. The electronic device (10) can control the switching circuit (731) so that the second electrical path (702) is substantially open during a first time interval in which transmission of a designated reference signal is not performed. The electronic device (10) can control the switching circuit (731) so that the second electrical path (702) can be connected to the fourth electrical path (704) or the fifth electrical path (705) during a second time interval in which transmission of a designated reference signal is performed.

[0091] For example, the electronic device (10) may control the switching circuit (731) to connect a designated impedance (Z) to a first point (P2) based on transmission of a data signal (e.g., an uplink signal not including SRS) via the first antenna (651). When the second electrical path (702) is viewed from the first point (P1), the second electrical path (702) may be substantially open. The designated impedance (Z) may have an impedance that exceeds the designated impedance for a frequency of a signal (e.g., a data signal or an uplink signal) transmitted via the first electrical path (701). The designated impedance (Z) may be an impedance mapped to a frequency of a signal (e.g., a data signal or an uplink signal) transmitted via the first electrical path (701). For example, the specified impedance (Z) may be a matching impedance that causes a leakage current into the second electrical path (702) to be substantially zero. For example, the specified impedance (Z) may be an impedance (e.g., an impedance higher than the matching impedance or an impedance lower than the matching impedance) that causes a signal loss due to a leakage current into the second electrical path (702) to be less than 0.2 dB.

[0092] In the present disclosure, an “open state” or “substantially open state” may include a case where the equivalent circuit of the corresponding path is open, an impedance of the corresponding path exceeds a critical impedance, and / or a case where the value of the leakage current into the corresponding path is below a threshold value. In one example, when the second electrical path (702) is substantially open, a signal loss due to a leakage current into the second electrical path (702) may be less than 0.2 dB. In the present disclosure, an “open state” may be referred to as a state where a signal of a corresponding frequency is not substantially transmitted through the corresponding path. Those skilled in the art will understand that an “open state” may include not only a theoretical open state but also an equivalent open state due to high impedance.

[0093] As the second electrical path (702) is controlled to be open, a signal applied to the first electrical path (701) by the transceiver (190c) can be radiated through the first antenna (651) without passing through the switching circuit (731) (e.g., by being bypassed). In this case, the electronic device (10) can control the first tuning circuit (641) so that the second electrical path (702) is in a substantially open state. Since the data signal is transmitted through the first electrical path (701) without passing through the switching circuit (731), insertion loss due to the switching circuit (731) can be reduced.

[0094] For example, the electronic device (10) can control the first switch (741) to connect the first impedance (Z0) to the second point (P2). The first impedance (Z0) can exceed a critical impedance for the frequency of the data signal to be transmitted. For example, the first impedance (Z0) can have an impedance for impedance matching of the first antenna (651) for the frequency of the data signal.

[0095] The structure of the communication module illustrated in FIG. 7A is an example, and embodiments of the present disclosure are not limited thereto. For example, although FIG. 7A illustrates three antennas, the communication module may include two or more antennas. The configuration of the second tuning circuit (642) and the third tuning circuit (643) illustrated in FIG. 7A is an example, and while a data signal is transmitted through the first electrical path (701), the second tuning circuit (642) and the third tuning circuit (643) may be set to any impedance.

[0096] FIG. 7b illustrates a connection setup for transmitting a reference signal through a first antenna of an electronic device according to one embodiment.

[0097] Referring to FIGS. 3 and 7B, according to one embodiment, the electronic device (10) may transmit a designated reference signal (e.g., SRS) through the first antenna (651). Based on the transmission of the designated reference signal, the electronic device (10) may control the switching circuit (731) to connect the second electrical path (702) with an antenna other than the first antenna (651) (e.g., the second antenna (652) or the third antenna (653)). For example, the electronic device (10) may use the switching circuit (731) to connect the second electrical path (702) with the fourth electrical path (704).

[0098] The reference signal applied by the transceiver (190c) may be distributed to the first electrical path (701) and the fourth electrical path (704). For example, the electronic device (10) may control the first tuning circuit (641) and the second tuning circuit (642) so that the impedance when looking at the first antenna (651) from the first point (P1) and the impedance when looking at the second antenna (652) from the first point (P1) are equal. The second tuning circuit (642) may be connected to the third impedance (Z2) through the second switch (742). The third impedance (Z2) may include, for example, a 50 ohm termination resistor. The first tuning circuit (641) may be connected to the first impedance (Z0) through, for example, the first switch (741). Since the impedances viewed from the first point (P1) are equal, the reference signal from the transceiver (190c) can be equally distributed from the first point (P1) to the first electrical path (701) and the second electrical path (702). The reference signal applied to the second electrical path (702) can be grounded through the fourth electrical path (704) and the second tuning circuit (642). The remaining reference signal can be radiated through the first antenna (651).

[0099] The configuration of the first tuning circuit (641) and the second tuning circuit (642) described with reference to FIG. 7B is an example, and embodiments of the present disclosure are not limited thereto. For example, the first tuning circuit (641) and the second tuning circuit (642) may be controlled to any value having an equal impedance with respect to the frequency of the reference signal when viewed from the first point (P1).

[0100] The SRS transmission method using the first antenna (651) described with reference to FIG. 7b is an example, and embodiments of the present disclosure are not limited thereto. For example, the electronic device (10) may transmit an SRS according to the settings for transmitting a data signal described above with reference to FIG. 7a.

[0101] FIG. 7c illustrates a connection setup for transmitting a reference signal via a second antenna of an electronic device according to one embodiment.

[0102] Referring to FIGS. 3 and 7C, according to one embodiment, the electronic device (10) may transmit a designated reference signal (e.g., SRS) through the second antenna (652). Based on the transmission of the designated reference signal, the electronic device (10) may control the switching circuit (731) to connect the second electrical path (702) with the fourth electrical path (704).

[0103] The reference signal applied by the transceiver (190c) may be distributed to the first electrical path (701) and the fourth electrical path (704). For example, the electronic device (10) may control the first tuning circuit (641) and the second tuning circuit (642) so that the impedance when looking at the first antenna (651) from the first point (P1) is equal to the impedance when looking at the second antenna (652) from the first point (P1). The second tuning circuit (642) may be connected to the first impedance (Z0) through the second switch (742). For example, the second tuning circuit (642) may be controlled to be in a substantially open state. In one example, the second tuning circuit (642) may be set to an impedance such that the terminal resistance for the second antenna (652) is 50 ohms.

[0104] The first tuning circuit (641) may be connected to a third impedance (Z2) via, for example, a first switch (741). The third impedance (Z2) may include, for example, an impedance that causes the termination resistance for the first antenna (651) to be 50 ohms. Since the impedances viewed from the first point (P1) are equal, the reference signal from the transceiver (190c) may be equally distributed from the first point (P1) to the first electrical path (701) and the second electrical path (702). The reference signal applied to the second electrical path (702) may be radiated via the second antenna (652). The remaining reference signal may be grounded via the first tuning circuit (641).

[0105] The configuration of the first tuning circuit (641) and the second tuning circuit (642) described with respect to FIG. 7C is an example, and embodiments of the present disclosure are not limited thereto. For example, the first tuning circuit (641) and the second tuning circuit (642) may be controlled to any value having an equal impedance with respect to the frequency of the reference signal when viewed from the first point (P1). However, unlike the embodiment of FIG. 7B, the signal may be radiated through the second antenna (652) instead of the first antenna (651).

[0106] FIG. 7d illustrates a connection setup for transmitting a reference signal through a third antenna of an electronic device according to one embodiment.

[0107] Referring to FIGS. 3 and 7D, according to one embodiment, the electronic device (10) may transmit a designated reference signal (e.g., SRS) through the third antenna (653). Based on the transmission of the designated reference signal, the electronic device (10) may control the switching circuit (731) to connect the second electrical path (702) with the fifth electrical path (705).

[0108] The reference signal applied by the transceiver (190c) may be distributed to the first electrical path (701) and the fifth electrical path (705). For example, the electronic device (10) may control the first tuning circuit (641) and the third tuning circuit (643) so that the impedance when looking at the first antenna (651) from the first point (P1) is equal to the impedance when looking at the third antenna (653) from the first point (P1). The third tuning circuit (643) may be connected to the first impedance (Z0) through the third switch (743). For example, the third tuning circuit (643) may be controlled to be in a substantially open state. In one example, the third tuning circuit (643) may be set to an impedance such that the terminal resistance for the third antenna (653) is 50 ohms.

[0109] The first tuning circuit (641) may be connected to a third impedance (Z2) via, for example, a first switch (741). The third impedance (Z2) may include, for example, an impedance that causes the terminal resistance for the first antenna (651) to be 50 ohms. Since the impedances viewed from the first point (P1) are equal, the reference signal from the transceiver (190c) may be equally distributed from the first point (P1) to the first electrical path (701) and the second electrical path (702). The reference signal applied to the second electrical path (702) may be radiated via the third antenna (653). The remaining reference signal may be grounded via the first tuning circuit (641).

[0110] The configuration of the first tuning circuit (641) and the third tuning circuit (643) described with reference to FIG. 7D is an example, and embodiments of the present disclosure are not limited thereto. For example, the first tuning circuit (641) and the third tuning circuit (643) may be controlled to any value having an equal impedance with respect to the frequency of the reference signal when viewed from the first point (P1).

[0111] With reference to FIGS. 7B to 7D , the settings of an electronic device (10) for transmitting a reference signal according to an embodiment of the present disclosure have been described. Since the reference signal is distributed through two electrical paths, the transmission power of the reference signal through all antennas can be set equally. In addition, as described above with reference to FIG. 7A , the data signal can be transmitted using a bypass path. Accordingly, the electronic device (10) can support transmission of a reference signal based on transmission antenna switching and reduce insertion loss due to antenna switching.

[0112] With reference to FIGS. 7A to 7D , examples of transmitting a reference signal (e.g., SRS) by a transceiver (190c) have been described. However, the examples of the present disclosure are not limited thereto. As described below with reference to FIGS. 8A to 8D , the reference signal may be generated by a component other than the transceiver (190c). In the examples of FIGS. 8A to 8D , unless otherwise described, the descriptions given above with reference to FIGS. 1 to 7D may be applied to components of the electronic device (10) having the same reference numbers.

[0113] FIG. 8A illustrates a connection setup for data transmission via a first antenna of an electronic device according to one embodiment.

[0114] Referring to FIGS. 3 and 8A, according to one embodiment, the electronic device (10) may include a reference signal generator (RS). The reference signal generator (RS) may include any RF circuit configured to generate a reference signal (e.g., SRS). The reference signal generator (RS) may be a component of the electronic device (10) excluding the transceiver (190c). In one example, the reference signal generator (RS) may be included in the processor (120) or a transceiver (not shown) other than the transceiver (190c).

[0115] In one example, the switching circuit (731) (e.g., the switching circuit (630) of FIG. 6) may include a dual-pole multi-throw (DPMT) switch. The switching circuit (731) may be configured to electrically connect the first point (P1) to the fourth electrical path (704), the fifth electrical path (705), or a designated impedance (Z). The switching circuit (731) may be configured to electrically connect the reference signal generator (RS) to the fourth electrical path (704) or the fifth electrical path (705).

[0116] According to one embodiment, the electronic device (10) may control the switching circuit (731) to cause the second electrical path (702) to be substantially open based on transmission of a data signal (e.g., an uplink signal not including SRS) through the first antenna (651). The transmission of the data signal through the first antenna (651) may be referred to as described with respect to FIG. 7A.

[0117] FIG. 8b illustrates a connection setup for transmitting a reference signal through a first antenna of an electronic device according to one embodiment.

[0118] Referring to FIGS. 3 and 8B, according to one embodiment, the electronic device (10) may transmit a designated reference signal (e.g., SRS) through the first antenna (651). Based on the transmission of the designated reference signal, the electronic device (10) may control the switching circuit (731) to connect the second electrical path (702) and the reference signal generator (RS) to the first port (N1). For example, the first port (N1) may correspond to a port of the switching circuit (731) connected to the fourth electrical path (704). The second port (N2) may correspond to a port of the switching circuit (731) connected to the fifth electrical path (705).

[0119] The reference signal applied by the reference signal generator (RS) can be distributed to the first electrical path (701) and the fourth electrical path (704). For example, the electronic device (10) can control the first tuning circuit (641) and the second tuning circuit (642) so that the impedance when looking at the first antenna (651) from the first port (N1) and the impedance when looking at the second antenna (652) from the first port (N1) are equal. The second tuning circuit (642) can be connected to the third impedance (Z2) through the second switch (742). The third impedance (Z2) can include, for example, a 50 ohm termination resistor. The first tuning circuit (641) can be connected to the first impedance (Z0) through, for example, the first switch (741). Since the impedances viewed from the first port (N1) are equal, the reference signal from the reference signal generator (RS) can be equally distributed from the first port (N1) to the second electrical path (702) and the fourth electrical path (704). The reference signal applied to the fourth electrical path (704) can be grounded through the second tuning circuit (642). The remaining reference signal can be radiated through the first antenna (651).

[0120] FIG. 8c illustrates a connection setup for transmitting a reference signal via a second antenna of an electronic device according to one embodiment.

[0121] Referring to FIGS. 3 and 8C, according to one embodiment, the electronic device (10) may transmit a designated reference signal (e.g., SRS) through the second antenna (652). Based on the transmission of the designated reference signal, the electronic device (10) may control the switching circuit (731) to connect the second electrical path (702) and the reference signal generator (RS) to the first port (N1).

[0122] The reference signal applied by the reference signal generator (RS) can be distributed to the first electrical path (701) and the fourth electrical path (704). For example, the electronic device (10) can control the first tuning circuit (641) and the second tuning circuit (642) so that the impedance when looking at the first antenna (651) from the first port (N1) and the impedance when looking at the second antenna (652) from the first port (N1) are equal.

The reference signal applied to the fourth electrical path (704) can be radiated through the second antenna (652).

In the example of FIG. 11, for convenience of explanation, a transmission method for the first antenna (651) is described, but a similar method may be applied to a transmission method using other antennas of the electronic device (10).

[0141] In operation 1105, the electronic device (10) may determine whether to transmit data via the first antenna (651). For example, the electronic device (10) may determine whether to transmit data based on wireless resource allocation information received from a base station and / or the presence of data scheduled to be transmitted.

In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among those phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0170] The term "module" used in various embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0171] Various embodiments of the present document may be implemented as software (e.g., a program (1240)) including one or more instructions stored in a storage medium (e.g., an internal memory (1236) or an external memory (1238)) readable by a machine (e.g., an electronic device (1201)). For example, a processor (e.g., a processor (1220)) of the machine (e.g., an electronic device (1201)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0172] According to one embodiment, the method according to various embodiments disclosed in this document may be provided as included in a computer program product. The computer program product may be traded as a commodity between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) via an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0173] According to various embodiments, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to various embodiments, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
