Description

Electronic device for transmitting reference signals and method of operation thereof

[0001] The present disclosure relates to an electronic device for transmitting a reference signal and an operating method thereof.

[0002] With recent advancements in mobile communication technology, the widespread use of mobile devices offering diverse functions has led to efforts to develop 5G communication systems to meet the growing demand for wireless data traffic. To achieve high data rates and provide faster data transfer speeds, 5G communication systems are being considered for implementation in higher frequency bands (e.g., 25-60 GHz) in addition to those used in 3G and LTE (long-term evolution) systems.

[0003] Stand-alone (SA) and non-stand-alone (NSA) methods are being considered for implementing 5G communications. Among these, the NSA method may include the EN-DC (E-UTRA NR dual connectivity) method, which utilizes the NR (new radio) system together with the existing LTE system. In the NSA method, the user terminal can utilize not only the eNB of the LTE system but also the gNB of the NR system. The technology that enables the user terminal to use different communication systems can be called dual connectivity. The EN-DC method for 5G is implemented by utilizing the dual connectivity proposed by 3GPP Release-12 by using the LTE network communication as the master node and the NR network communication as the secondary node.

[0004] Meanwhile, the electronic device may transmit a reference signal (e.g., a sounding reference signal (SRS)) referenced for channel estimation at a base station of a communication network through at least one antenna. The base station may perform multi-antenna signal processing or beamforming processing by estimating the channel based on the reference signal transmitted from the electronic device. The electronic device may improve data reception performance by receiving a signal processed through multi-antenna signal processing or beamforming from the base station.

Referring to FIG. 2A, the electronic device (101) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a portion of the wireless communication module (192). According to another embodiment, the fourth RFIC (228) may be omitted or may be included as a part of the third RFIC (226).

[0052] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. According to one embodiment, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. According to one embodiment, the second cellular network (294) may be a 5G network defined by 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0053] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0054] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.

[0055] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package. According to one embodiment, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2B, the integrated communication processor (260) may support functions for communicating with both the first cellular network (292) and the second cellular network (294).

[0056] As described above, at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260) may be implemented as a single chip or a single package. In this case, the single chip or single package may include a memory (or storage means) that stores instructions that cause the performance of at least some of the operations performed according to one embodiment, and a processing circuit (or, the name thereof is not limited, such as an arithmetic circuit) for executing the instructions.

[0057] The first RFIC (222) may, upon transmission, convert a signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in a first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a signal that may be processed by the first communication processor (212).

[0058] The second RFIC (224) may, upon transmission, convert a signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a signal that may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0059] The third RFIC (226) can convert a signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in a second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., a 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a signal that can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0060] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a signal that can be processed by the second communication processor (214).

[0061] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to an example, at least one antenna module among the first antenna module (242) or the second antenna module (244) can be omitted or combined with another antenna module to process RF signals of corresponding multiple bands.

[0062] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0063] According to an exemplary embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0064] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0065] FIG. 3 is a diagram illustrating wireless communication systems providing a network of legacy communication and / or 5G communication according to one embodiment.

[0066] Referring to FIG. 3, the network environment (300c) 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 (e.g., an eNodeB (eNB)) of the 3GPP standard that supports wireless connection with the electronic device (101) and an evolved packet core (EPC) that manages 4G communication. The 5G network may include, for example, a New Radio (NR) base station (e.g., a gNodeB (gNB)) that supports wireless connection with the electronic device (101) and a 5th generation core (5GC) that manages 5G communication of the electronic device (101).

[0067] According to one embodiment, the electronic device (101) can 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 (101). The user data may refer to, for example, user data excluding control messages transmitted and received between the electronic device (101) and the core network (330) (e.g., EPC).

[0068] Referring to FIG. 3, an electronic device (101) according to one embodiment can transmit and receive at least one of a control message or user data to and from at least a part of a 5G network (e.g., an NR base station, 5GC) using at least a part of a legacy network (e.g., an LTE base station, EPC).

[0069] According to one embodiment, the network environment (300c) may include a network environment that provides wireless communication dual connectivity (DC) to an LTE base station and an NR base station, and transmits and receives control messages with an electronic device (101) through a core network (330) of one of EPC or 5GC.

[0070] According to one embodiment, in a DC environment, one of the LTE base stations or the NR base station may operate as a master node (MN) (310) and the other may operate as a secondary node (SN) (320). The MN (310) may be connected to a core network (330) and may transmit and receive control messages. The MN (310) and the SN (320) 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.

[0071] According to one embodiment, in EN-DC (E-UTRA new radio dual connectivity), the MN (310) may be configured as an LTE base station, the SN (320) as an NR base station, and the core network (330) as an EPC. For example, control messages may be transmitted and received through the LTE base station and the EPC, and user data may be transmitted and received through at least one of the LTE base station and the NR base station.

[0072] According to one embodiment, in NE-DC (new radio dual E-UTRA connectivity), the MN (310) may be configured as an NR base station, the SN (320) as an LTE base station, and the core network (330) as a 5GC. For example, control messages may be transmitted and received through the NR base station and the 5GC, and user data may be transmitted and received through at least one of the LTE base station or the NR base station.

[0073] According to one embodiment, the electronic device (101) can be registered with at least one of EPC or 5GC to transmit and receive control messages.

[0074] In one embodiment, the EPC or 5GC may interwork to manage communication of the electronic device (101). For example, movement information of the electronic device (101) may be transmitted and received through an interface between the EPC and 5GC.

[0075] Meanwhile, MR DC can be applied in various ways other than EN-DC. For example, the first and second networks based on MR DC can both be related to LTE communication, and the second network can be a network corresponding to small cells of a specific frequency. For example, the first and second networks based on MR DC can both be related to 5G, and the first network can correspond to a frequency band below 6 GHz (e.g., below 6), and the second network can correspond to a frequency band above 6 GHz (e.g., over 6). In addition to the examples described above, those skilled in the art will readily understand that any network structure capable of dual connectivity can be applied to an embodiment of the present disclosure.

[0076] FIG. 4 is a diagram illustrating reference signal transmission of an electronic device according to one embodiment. Referring to FIG. 4, an electronic device (101) (e.g., the electronic device (101) of FIG. 1) may transmit a reference signal (e.g., SRS) through four antennas (e.g., a first antenna (411), a second antenna (412), a third antenna (413), and a fourth antenna (414)). For example, the electronic device (101) may amplify the reference signal through at least one power amplifier (PA) (415), and transmit the amplified reference signal through at least one switch (416) to the first antenna (411), the second antenna (412), the third antenna (413), and the fourth antenna (414). A reference signal (e.g., SRS) transmitted through each antenna (e.g., first antenna (411), second antenna (412), third antenna (413), fourth antenna (414)) of the electronic device (101) can be received through each antenna (421) of the base station (420) (e.g., gNB).

[0077] According to one embodiment, the base station (420) may receive a reference signal transmitted from the electronic device (101) and estimate a channel for each antenna (e.g., first antenna (411), second antenna (412), third antenna (413), and fourth antenna (414)) of the electronic device (410) from the received reference signal. The base station (420) may transmit a precoded downlink signal to the electronic device (101) based on the channel estimation. For example, the electronic device (101) and the base station (420) may perform MIMO communication. According to one embodiment, the base station (420) may also perform beamforming based on the channel estimation in the FR2 band.

[0078] In Fig. 4, for convenience of explanation, the power amplifier (415) and the switch (416) are shown as one and connected to a plurality of antennas (the first antenna (411), the second antenna (412), the third antenna (413), and the fourth antenna (414)), but those skilled in the art will readily understand that this is not limited thereto.

[0079] As illustrated in FIG. 4, when an electronic device (101) transmits a reference signal (e.g., SRS) through multiple transmission paths, a base station (420) can check a channel environment with each antenna (e.g., a first antenna (411), a second antenna (412), a third antenna (413), a fourth antenna (414)) of the electronic device (101) and use this for precoding (or beamforming), and as a result, a reference signal received power (RSRP) and / or a signal to noise ratio (SNR) of a downlink channel can be improved. When the RSRP and / or SNR of a downlink channel are improved, a rank index (RI) or a channel quality indicator (CQI) for the corresponding electronic device can be increased. The base station (420) may assign a high rank or MCS (modulation and code schemes) to the electronic device (101) based on the improved performance of the electronic device (101), thereby improving the downlink throughput of the electronic device (101).

[0080] According to one embodiment, the base station (420) may use a downlink reference signal for downlink channel estimation. For example, when the base station (420) transmits a downlink reference signal to the electronic device (101), the electronic device (101) may receive the downlink reference signal transmitted from the base station (420) and perform channel estimation. The electronic device (101) may transmit the result of the channel estimation to the base station (420), and the base station (420) may perform downlink beamforming with reference to the result of the channel estimation transmitted from the electronic device (101). According to one embodiment, when the base station (420) performs channel estimation based on a reference signal (e.g., SRS) transmitted by the electronic device (101), the channel estimation may be performed more quickly than channel estimation based on the downlink reference signal.

[0081] According to one embodiment, a first communication network (e.g., a base station (gNB)) or a second communication network (e.g., a base station (eNB)) may request various configuration information of the electronic device (101) by transmitting a UE Capability Enquiry message to the electronic device (101). For example, the first communication network (e.g., a base station (gNB)) or the second communication network (e.g., a base station (eNB)) may request information related to a receiving antenna of the electronic device (101) through the UE Capability Enquiry message. The electronic device (101) may receive the UE Capability Enquiry message from the first communication network or the second communication network, and transmit a UE Capability Information message to the first communication network or the second communication network in response thereto. According to one embodiment, the UE Capability Information message may include information related to the receiving antenna of the electronic device (101), such as 'supportedSRS-TxPortSwitch t1r4', corresponding to the content of the UE Capability Enquiry message.

[0082] As information related to the antenna is described as 'supportedSRS-TxPortSwitch t1r4', the first communication network determines that the electronic device (101) can transmit a signal using four receiving antennas, and can transmit information about when to transmit a reference signal (e.g., SRS) for each of the four antennas by including it in the RRC Reconfiguration message.

[0083] FIG. 5 illustrates a flowchart for explaining a signal transmission and reception procedure between an electronic device and a communication network according to one embodiment. Referring to FIG. 5, an electronic device (101) may establish an RRC connection with a first communication network (e.g., a base station (gNB)) (600) through a random access channel (RACH) procedure.

[0084] According to one embodiment, in operation 510, the first communication network (500) may transmit an RRC Reconfiguration message to the electronic device (101). For example, the first communication network (500) may transmit the RRC Reconfiguration message in response to an RRC Request message transmitted by the electronic device (101). As described above, the RRC Reconfiguration message may include information regarding when the electronic device (101) transmits a reference signal (e.g., SRS) for each antenna, as follows.

[0087] peridicityAndOffset-p s120:13

[0088] peridicityAndOffset-p s120:3

[0089] nrofSymbols n1

[0090] Referring to the RRC Reconfiguration message, it can be seen that the duration of transmitting the SRS can be determined by the allocated symbols, as described as "nrofSymbols n1." Also, referring to the RRC Reconfiguration message, the first SRS is set to be transmitted in the 17th slot at a frequency of once every 20 slots, as described in "periodicityAndOffset-p s120:17", the second SRS is set to be transmitted in the 7th slot at a frequency of once every 20 slots, as described in "periodicityAndOffset-p s120:7", the third SRS is set to be transmitted in the 13th slot at a frequency of once every 20 slots, as described in "periodicityAndOffset-p s120:13", and the fourth SRS is set to be transmitted in the 3rd slot at a frequency of once every 20 slots, as described in "periodicityAndOffset-p s120:3".

[0091] According to one embodiment, the electronic device (101) may transmit four SRSs through each antenna at different times every 20 slots according to the setting of RRC Reconfiguration. The size of one slot may be determined by subcarrier spacing (SCS). For example, when the SCS is 30 KHz, the time interval of one slot may be 0.5 ms, and the time interval of 20 slots may be 10 ms. Accordingly, the electronic device (101) may repeatedly transmit SRSs through each antenna at different times every 10 ms period. According to one embodiment, one slot may include 14 symbols, and assuming that one symbol is allocated for transmission of one SRS, it may have a symbol duration (or symbol enable time) of 0.5 ms * 1 / 14 = 35 μs (0.035 ms).

[0092] According to one embodiment, in operation 520, the electronic device (101) may transmit an RRC Reconfiguration Complete message to the first communication network (500). As the RRC Reconfiguration procedure is normally completed, in operation 530, the electronic device (101) and the first communication network (600) may complete RRC connection setup.

[0093] According to one embodiment, the electronic device (101) may transmit a reference signal at different times for each set time period (e.g., 10 ms) through each antenna transmission path based on information regarding the transmission time of the reference signal (e.g., SRS) received from the first communication network (500) as described above.

[0094] FIG. 6 is a diagram showing a transmission period of a reference signal according to one embodiment. Referring to FIG. 6, for example, the electronic device (101) may transmit a first SRS in the 17th slot out of 20 slots every 10 ms, a second SRS in the 7th slot, a third SRS in the 13th slot, and a fourth SRS in the 3rd slot. For example, the electronic device (101) may support 1T4R (e.g., a scenario in which one antenna out of four receiving antennas is mapped for transmission purposes and transmitted), and may include four receiving antennas. The electronic device (101) may transmit an SRS signal through each of the four receiving antennas (e.g., RX0, RX1, RX2, and RX3 of FIG. 6).

[0095] According to one embodiment, the reference signal may be, but is not limited to, a sounding reference signal (SRS) used for multi-antenna signal processing (e.g., multi-input multi-output (MIMO) or beamforming) through uplink channel state measurement. For example, in the above description or the description to be described below, the SRS is described as an example of the reference signal, but any type of uplink reference signal (e.g., uplink demodulation reference signal (DM-RS)) transmitted from the electronic device (101) to the base station may be included in the reference signal described below.

[0096] Figures 7a and 7b are diagrams for explaining requirements based on a transmission signal during hearing aid activation.

[0097] Referring to Fig. 7a, when viewed from a planar view (101a), an area (701) related to hearing aid compatibility (HAC) with an electronic device (101) may be defined, for example, by the American National Standard Institute (ANSI). In the area (701), 676 points (26 points X 26 points) defined by, for example, 26 points horizontally and 26 points vertically may be defined. For example, in the C63.19-2019 standard, requirements for ABM (Audio Band Magnetic) measurement values ​​are disclosed when tested in a non-2G-GSM (global system for mobile) condition (Non-2G GSM operating mode). For example, one requirement, as a condition for qualifying field strengths in ANSI C63.19-2019, 6.6.2 T-Coil coupling, may be referred to as the ABM1 condition for a group called the primary group. The AM1 condition (e.g., (ANSI C63.19-2019, 6.6.4.2 Non-2G) requires that, under experimental conditions of a frequency of 1 kHz and a 1 / 3 octaveband filter, there be at least 75 points out of 676 points in the range (701) of FIG. 7a where the H-Field measurement by the desired signal is greater than or equal to -18 dB(A / m).

[0098] In addition, the ABM2 condition, defined as a secondary group, may require that, while satisfying the ABM1 condition, there be at least 300 consecutive points where the H-Field measurement value due to an additional undesired signal is -38 dB (A / m) or less, for example, among the 676 points in the range (701) of FIG. 7a (e.g., ANSI C63.19-2019, 6.6.4.2 Non-2G GSM operating modes). For example, the larger the size of the transmission signal used for RF (radio frequency) communication, the more difficult it is to satisfy the ABM2 condition due to the effect of increasing the H-Field value due to the generated undesired signal. For example, the RF signal generated from the first antenna (411) of FIG. 7a may affect the area (701) as a victim as an aggressor. For example, if the electronic device (101) is implemented in a high power class (e.g., power class 1.5 or power class 2), it is difficult to satisfy the ABM2 condition.

[0099] For example, referring to FIG. 7B, it can be confirmed that the region (701) of FIG. 7A is expressed as four divided regions (711, 712, 713, 714). FIG. 7B is an example measured when the n77 band of NR (new radio) operates in standalone (SA) mode based on the first antenna (411). For example, region (711) may refer to a region that satisfies the ABM2 condition while not satisfying the AM1 condition. For example, region (712) may refer to a region that satisfies the ABM1 condition while satisfying the ABM2 condition. For example, region (713) may be a region that does not satisfy the ABM1 condition and does not satisfy the AMB2 condition. For example, region (714) may be a region that satisfies the ABM1 condition but does not satisfy the ABM2 condition. For example, the number of points associated with the ABM2 condition may be 197, which may be less than 300 required by the ABM2 condition. According to one embodiment, as described with reference to FIG. 4, the electronic device (101) may have a plurality of RF paths (e.g., RF paths based on antennas (411, 412, 413, 414)) for SRS transmission. The electronic device (101) may perform at least one operation for transmitting an RF signal using at least some of the antennas (412, 413, 414) other than the TX / PRX (transmission / primary reception) antenna (e.g., the first antenna (411)) in order to satisfy the condition associated with HAC. Accordingly, RF signal transmission based on an antenna other than the first antenna (411) may be performed, so that the condition associated with HAC may be satisfied.

[0100] FIG. 8 is a diagram for explaining an operation method of an electronic device according to one embodiment. The embodiment of FIG. 8 will be explained with reference to FIGS. 9a and 9b. FIGS. 9a and 9b are diagrams for explaining the operation of a switch included in an RF circuit according to embodiments.

[0101] According to one embodiment, the electronic device (101) may, in operation 801, detect an event associated with hearing aid activation. For example, the electronic device (101) may detect the establishment of a wireless connection with a hearing aid (e.g., but not limited to, the electronic device (102)) as an event associated with hearing aid activation. For example, the electronic device (101) may detect the confirmation of a wired connection with the hearing aid as an event associated with hearing aid activation. For example, the electronic device (101) may detect a user input via a user interface as an event associated with hearing aid activation. For example, the electronic device (101) may detect the confirmation of a user's proximity (e.g., proximity to a receiver) after the hearing aid has been activated as an event associated with hearing aid activation. Meanwhile, there are no limitations on the events associated with hearing aid activation.

[0102] The electronic device (101), in operation 803, may select a first RF path among a first plurality of RF paths for transmitting the SRS. For example, a communication processor (e.g., at least one processor among 212, 214 of FIG. 2A, and 260 of FIG. 2B) may select the RF path, and may select the first RF path based on receiving a notification of a hearing aid activation event from the application processor (120), but is not limited thereto. The electronic device (101), in operation 805, may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path. For example, referring to FIG. 9A, the electronic device (101) may include an RF circuit (910) and / or a second switch (914), and the RF circuit (910) may be implemented with, for example, a PAMid, but is not limited thereto in implementation examples. The RF circuit (910) may include at least one amplifier (911), a first switch (913), and / or at least one LNA (912). The first switch (913) may be configured to connect an output terminal of the amplifier (911) to at least one of a first port (921) or a second switch (914). For example, the first port (912) may be connected to a TX / PRX antenna (e.g., the first antenna (411) of FIG. 4), but is not limited thereto. For example, the second switch (914) may be configured to connect the first switch (913) to at least one of a second port (922), a third port (923), or a fourth port (924). For example, each of the second port (922), the third port (923), or the fourth port (924) may be connected to the remaining antennas for SRS transmission (e.g., the antennas (412, 413, 414) of FIG. 4).For example, as in FIG. 9A, when the first switch (913) is controlled to connect the output terminal of the amplifier (911) to the first port (921), an RF signal (hereinafter, referred to as a transmission signal) for transmission by the amplifier (911) can be provided to the first antenna (411), which is a TX / PRX antenna, through the first port (921). For example, the transmission signal can include a signal associated with a physical uplink shared channel (PUSCH), a signal associated with a physical uplink control channel (PUCCH), and / or a signal associated with a physical random access channel (PRACH), but there is no limitation on the type thereof. The path by the amplifier (911), the first port (921), and / or the first antenna (411) can also be referred to as a first RF path (931). For example, the electronic device (101) may utilize the first RF path (931) associated with the first antenna (411), which is a TX / PRX antenna, when no event associated with hearing aid activation is detected.

[0103] For example, when an event associated with hearing aid activation is detected, the electronic device (101) may select at least one of the antennas (412, 413, 414) other than the first antenna (411), which is a TX / PRX antenna, among the antennas (411, 412, 413, 414) associated with transmission of SRS. The electronic device (101) may control the RF circuit so that a transmission signal is transmitted based on the identified antenna. For example, the distance from the identified antenna to the area (701) may be smaller than the distance from the first antenna (411) to the area (701). Accordingly, the impact on the area (701) when a transmission signal is transmitted by the identified antenna may be smaller than the impact on the area (701) when a transmission signal is transmitted by the first antenna (411).

[0104] For example, the electronic device (101) can compare the priorities of each of the antennas (412, 413, 414) and select the antenna with the highest priority based on the comparison result. The priorities can be set based on the reception strength (e.g., RSRP (reference signal received power), RSRQ (reference signal received quality), RSSI (received signal strength indicator), and / or SINR (signal to interference plus noise ratio), but there is no limitation) of each of the antennas (412, 413, 414). For example, the priority can be set relatively higher as the reception strength is relatively higher. Meanwhile, those skilled in the art will understand that, in addition to the reception strength, any parameter that can represent an electric field can be used when determining priorities.

[0105] For example, in FIG. 9B, the electronic device (101) may select the fourth antenna (414) as an antenna for transmitting a transmission signal. The electronic device (101) may control an RF circuit, for example, a first switch (913), so that a signal amplified by the amplifier (911) is provided to the fourth antenna (414). For example, the electronic device (101) may control the first switch (913) so that the output terminal of the amplifier (911) is connected to the fifth port (925). Accordingly, the amplifier (911) may be connected to the fourth antenna (414). Accordingly, a transmission signal may be provided along an RF path (933) based on the fourth antenna (414). Since the transmission signal is transmitted by an antenna other than the first antenna (411) (e.g., the fourth antenna (414)), an HAC-related condition may be satisfied.

[0106] For example, Table 1 shows the number of points in the secondary group corresponding to each of the multiple antennas confirmed through the experiment.

[0107] Number of points in the antenna secondary group 1st antenna (411) 288 2nd antenna (412) 323 3rd antenna (413) 310 4th antenna (414) 314

[0108] The experiment in Table 1 is data confirmed when a transmission signal is transmitted in the n77 band, for example. The experimental conditions are that the bandwidth is 100 MHz, the modulation method is DFT-s-OFDM (discrete Fourier transform-spread-orthogonal frequency division multiplexing) 16 QAM (quadrature amplitude modulation), the position / number of RB (resource block) is 1RB offset / 1RB, the channel is 656000, and the transmission power is 16 dBm. As shown in Table 1, the first antenna (411), which is a TX / PRX antenna, does not satisfy the HAC condition because the number of points in the secondary group is 288, but it can be confirmed that the other antennas (412, 413, 414) satisfy the HAC condition because the number of points in the secondary group is 300 or more.

[0109] FIG. 10 is a flowchart for explaining an operating method of an electronic device according to one embodiment.

[0110] According to one embodiment, the electronic device (101) may control the RF circuit to transmit a first transmission signal of a first operating band using a first RF path corresponding to a TX / PRX antenna for the first operating band while an event associated with hearing aid activation is not detected in operation 1001. For example, the TX / PRX antenna may be configured for each operating band available to the electronic device (101). The electronic device (101) may use the first RF path based on the corresponding TX / PRX antenna while an event associated with hearing aid activation is not detected. While using the first RF path based on the TX / PRX antenna, the electronic device (101) may detect an event associated with hearing aid activation in operation 1003. For example, For example, the electronic device (101) may detect the establishment of a wireless connection with a hearing aid (which may be, for example, but is not limited to, the electronic device (102)) as an event associated with hearing aid activation. For example, the electronic device (101) may detect the confirmation of a wired connection with the hearing aid as an event associated with hearing aid activation. For example, the electronic device (101) may detect a user input via a user interface as an event associated with hearing aid activation. For example, the electronic device (101) may detect the confirmation of a user's proximity (for example, proximity to a receiver) after the hearing aid has been activated as an event associated with hearing aid activation. Meanwhile, there is no limitation on the events associated with hearing aid activation. The electronic device (101) may, in operation 1005, control the RF circuit to transmit a second transmission signal in the first operating band using a second RF path corresponding to the DRX antenna among a plurality of paths for SRS transmission. For example, the electronic device (101) can check the priority of each RF path corresponding to the DRX antenna among a plurality of paths for SRS transmission.The electronic device (101) may select a DRX antenna based on, for example, the reception strength associated with each of the DRX antennas. In one example, the electronic device (101) may select the DRX corresponding to the greatest reception strength, but this is exemplary. The electronic device (101) may utilize the RF path (931) for the TX / PRX antenna by controlling the first switch (913) to connect the amplifier (911) to the first port (921) allocated for the TX / PRX antenna, for example, as in FIG. 9A, while no event associated with hearing aid activation is detected. The electronic device (101) can utilize the RF path (933) for the selected DRX antenna by controlling the first switch (913) to connect the amplifier (911) to the fourth port (924) allocated for the selected DRX antenna, for example, as in FIG. 9b, based on the detection of an event associated with hearing aid activation.

[0111] For example, the electronic device (101) may be configured to change the antenna for transmission from the TX / PRX antenna to the DRX antenna based on the detection of an event associated with hearing aid activation when the TX / PRX antenna is in proximity to the area (701) (or the receiver) (e.g., positioned within a specified distance). For example, the electronic device (101) may maintain the use of the TX / PRX antenna even if the detection of an event associated with hearing aid activation is not when the TX / PRX antenna is in proximity to the area (701) (or the receiver) (e.g., positioned outside a specified distance). For example, the electronic device (101) may be configured to change the antenna for transmission from the TX / PRX antenna to the DRX antenna based on detecting an event associated with hearing aid activation when the TX / PRX antenna is in proximity to the area (701) (or receiver) (e.g., positioned within a specified distance) and the DRX antenna is not in proximity to the area (701) (or receiver) (e.g., positioned outside the specified distance).

[0112] FIG. 11 is a flowchart for explaining an operating method of an electronic device according to one embodiment.

[0113] According to one embodiment, the electronic device (101) may, in operation 1101, detect an event associated with hearing aid activation. For example, the electronic device (101) may detect the establishment of a wireless connection with a hearing aid (e.g., but not limited to, the electronic device (102)) as an event associated with hearing aid activation. For example, the electronic device (101) may detect confirmation of a wired connection with the hearing aid as an event associated with hearing aid activation. For example, the electronic device (101) may detect user input via a user interface as an event associated with hearing aid activation. For example, the electronic device (101) may detect confirmation of a user's proximity (e.g., proximity to a receiver) after the hearing aid has been activated as an event associated with hearing aid activation. Meanwhile, there are no limitations on the events associated with hearing aid activation. The electronic device (101), in operation 1103, can check information related to the reception strength of each of the plurality of RF paths. Meanwhile, those skilled in the art will understand that there is no limitation on the timing of measuring the reception strength of each of the plurality of RF paths, and it may be before or after event detection. The electronic device (101), in operation 1105, can select a first RF path based on the information related to the reception strength of each of the plurality of RF paths. For example, the electronic device (101), based on the information related to the reception strength of each of the plurality of RF paths, can select an antenna with the highest reception strength among the remaining DRX antennas excluding the TX / PRX antennas. As described above, those skilled in the art will understand that the reception strength may be expressed as RSRP, RSRQ, RSSI, and / or SINR, and may be set as a sum (or weighted sum) of a plurality of parameters.Accordingly, the electronic device (101) can transmit a transmission signal using an antenna determined to have the best electric field among the DRX antennas excluding the TX / PRX antenna.

[0114] FIG. 12a is a flowchart for explaining an operation method of an electronic device according to an embodiment.

[0115] According to one embodiment, the electronic device (101) may detect an event associated with hearing aid activation in operation 1201. The electronic device (101) may check information related to reception strength of each of the plurality of RF paths in operation 1203. The electronic device (101) may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path in operation 1205. For example, the electronic device (101) may control the RF circuit to transmit a transmission signal for at least a portion of PUCCH, PUSCH, and / or PRACH using the first RF path. The electronic device (101) may perform an SRS operation based on the plurality of RF paths in operation 1207. For example, the electronic device (101) may perform the SRS transmission based on the plurality of antennas (411, 412, 413, 414). For example, the electronic device (101) may adjust the transmission power when transmitting SRS to the first antenna (411), but there is no limitation.

[0116] Fig. 12b is a flowchart for explaining an operation method of an electronic device according to an embodiment.

[0117] According to one embodiment, the electronic device (101) may detect an event associated with hearing aid activation in operation 1211. The electronic device (101) may check information related to reception strength of each of a plurality of RF paths in operation 1213. The electronic device (101) may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path in operation 1215. For example, the electronic device (101) may control the RF circuit to transmit a transmission signal for at least a portion of PUCCH, PUSCH, and / or PRACH using the first RF path. The electronic device (101) may perform an SRS operation based on at least a portion of the remaining RF paths that are different from the RF path corresponding to the TX / PRX antenna in operation 1217. For example, the electronic device (101) can transmit an SRS using an RF path corresponding to at least some of the remaining antennas (412, 413, 414) excluding the first antenna (411). For example, the electronic device (101) can perform SRS transmission based on at least some of the remaining antennas (412, 413, 414) at four SRS transmission points provided from the network while maintaining the UEcapability of 1t4r. For example, at least one of the remaining antennas (412, 413, 414) may be used for multiple SRS transmissions. For example, the electronic device (101) may change the UEcapability from 1t4r to 1t2r and report this to the network.

[0118] FIG. 13a is a diagram for explaining the operation of an electronic device and a network according to one embodiment.

[0119] According to one embodiment, the electronic device (101) may detect an event associated with hearing aid activation in operation 1301. The electronic device (101) may select a first RF path among RF paths for transmitting an SRS in operation 1303. The electronic device (101) may select the first RF path based on a priority (e.g., reception strength, but not limited to) of each of the remaining paths, excluding an RF path associated with a TX / PRX antenna, among the RF paths for transmitting an SRS. The electronic device (100) may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path in operation 1305. The first communication network (500) may determine the reception strength of the uplink signal in operation 1307. For example, as an RF path other than the RF path associated with the TX / PRX antenna is utilized, the reception strength of an uplink signal received in the first communication network (500) may decrease. The first communication network (500) may, based on the decrease in the reception strength of the uplink signal (or based on the reception strength being below a threshold reception strength), request an adjustment of the transmission power of the uplink signal in operation 1309. For example, the adjustment of the transmission power may include, but is not limited to, information requesting an increase in the transmission power. The electronic device (101), despite receiving a request for adjusting the transmission power of the uplink signal, may, in operation 1311, suspend (or ignore or discard) the adjustment of the transmission power of the uplink signal. As the transmission power of the uplink signal increases, the intensity of the electromagnetic field radiated based on the first RF path may also increase, which may potentially cause a violation of the HAC condition.Accordingly, the electronic device (101) may postpone (or ignore or discard) the adjustment of the transmission power of the uplink signal even though it receives a request for adjustment of the transmission power of the uplink signal, and the HAC condition may not be violated.

[0120] FIG. 13 b is a diagram for explaining the operation of an electronic device and a network according to one embodiment.

[0121] According to one embodiment, the electronic device (101) may detect an event associated with hearing aid activation in operation 1321. The electronic device (101) may select a first RF path among RF paths for transmitting the SRS in operation 1323. The electronic device (101) may select the first RF path based on a priority (e.g., reception strength, but not limited to) of each of the remaining paths, excluding the RF path associated with the TX / PRX antenna, among the RF paths for transmitting the SRS. The electronic device (100) may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path in operation 1325. The first communication network (500) may determine the reception strength of the uplink signal in operation 1327. For example, as an RF path other than the RF path associated with the TX / PRX antenna is utilized, the reception strength of the uplink signal received in the first communication network (500) may decrease. The first communication network (500) may request an adjustment of the transmission power of the uplink signal in operation 1209 based on the decrease in the reception strength of the uplink signal (or based on the reception strength being less than or equal to a threshold reception strength). The electronic device (101) may adjust the transmission power of the uplink signal to be less than or equal to a maximum transmission power associated with hearing aid activation in operation 1331. Here, the maximum transmission power associated with hearing aid activation may be a value set to satisfy the HAC condition, but is not limited thereto. For example, the electronic device (101) may increase the transmission power of the uplink signal based on the request to increase the transmission power of the uplink signal when the transmission power of the current uplink signal is less than the maximum transmission power associated with hearing aid activation.For example, the electronic device (101) may postpone (or ignore or discard) a request to increase the transmission power of the uplink signal if the transmission power of the current uplink signal is greater than or equal to the maximum transmission power associated with hearing aid activation. If the transmission power of the current uplink signal exceeds the maximum transmission power associated with hearing aid activation, the electronic device (101) may also reduce the transmission power of the current uplink signal to be less than or equal to the maximum transmission power associated with hearing aid activation.

[0122] FIG. 14 is a diagram for explaining the operation of an electronic device and a network according to one embodiment.

[0123] According to one embodiment, the electronic device (101) may detect an event associated with hearing aid activation in operation 1401. In operation 1403, the electronic device (101) may identify a first RF path designated in advance among a first plurality of RF paths for transmitting an SRS. For example, in the embodiment of FIG. 14, an RF path for satisfying an HAC condition may be preset. In this case, the electronic device (101) may identify the first RF path designated in advance among the first plurality of RF paths for transmitting an SRS without any additional judgment. Here, the first RF path may be, for example, an RF path that has been identified as having relatively good communication quality compared to other RF paths while satisfying the HAC condition, but there is no limitation on the designation condition. In operation 1405, the electronic device (101) may control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path.

[0124] FIG. 15 is a diagram for explaining the operation of an electronic device and a network according to one embodiment.

[0125] According to one embodiment, the electronic device (101) may, in operation 1501, detect an event associated with hearing aid activation. The electronic device (101) may, in operation 1503, select a first RF path among a first plurality of RF paths for transmitting an SRS. The electronic device (101) may select the first RF path based on a priority (e.g., reception strength, but not limited to) of each of the remaining paths, excluding an RF path associated with a TX / PRX antenna, among the RF paths for transmitting the SRS. The electronic device (100) may, in operation 1505, control the RF circuit to transmit at least a portion of at least one transmission signal using the first RF path. The electronic device (101) may, in operation 1507, detect an event associated with hearing aid deactivation. The electronic device (101) may, for example, detect a release of a wireless connection with a hearing aid (which may be, but is not limited to, the electronic device (102)) as an event associated with hearing aid deactivation. For example, the electronic device (101) may detect a release of a wired connection with the hearing aid as an event associated with hearing aid deactivation. For example, the electronic device (101) may detect a user input via a user interface as an event associated with hearing aid deactivation. The electronic device (101) may, at operation 1509, control the RF circuitry to transmit at least a portion of the at least one transmit signal using a second RF path that is different from the first RF path. For example, the electronic device (101) may transmit at least a portion of the at least one transmit signal using an RF path associated with a TX / PRX antenna as the second RF path, but this is by way of example only and is not limiting.
