Description

[0001] Cross Reference to Related Applications

[0002] This application is a follow-up application of International Application PCT / KR2021 / 006951 filed on June 3, 2021, based on and claiming the benefit of Korean Patent Application 10-2020-0095239 filed with the Korean Intellectual Property Office on July 30, 2020, the disclosure of which is incorporated herein in its entirety by reference. TECHNICAL FIELD

[0003] The disclosure relates to a method and an electronic device for controlling transmission power of a multi-beam transmission. BACKGROUND

[0004] To meet growing demands for network traffic, fifth generation (5G) mobile communication technologies have been developed. For example, millimeter wave (mmWave) (e.g., a signal of 20 gigahertz (GHz) to 200 GHz band), in which a signal having a wavelength of several millimeters is used, can be used for fifth generation mobile communication. In general, in order to smoothly provide a wireless communication service in a high frequency band, it is necessary to reduce path loss of a radio wave and increase a propagation distance of the radio wave. For these reasons, a mobile electronic device performs beamforming in a 5G communication system. Unlike an omnidirectional beam pattern, a beam pattern of beamforming of an electronic device can have relatively high directivity.

[0005] When an electronic device communicates using beamforming, the electronic device can perform communication with a beam having a relatively sharp beam pattern. The electronic device can use a plurality of antenna arrays in order to generate beam coverage in a plurality of directions of the electronic device. Each of the plurality of antenna arrays can be located inside a housing of the electronic device to form a beam in a different direction.

[0006] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure. SUMMARY

[0007] An electronic device can communicate with a base station by transmitting a wireless signal of a specific frequency. A mobile electronic device such as a smartphone can be placed close to a user to transmit / receive a wireless signal. The electronic device can control transmission power in order to reduce the impact of the wireless signal on the user. For example, the electronic device can control transmission power based on a specific absorption rate (SAR) limit. The SAR limit can be set based on the amount of radio frequency energy absorbed by a human body per unit time. In the case of a high frequency band signal, the electronic device can control transmission power based on a maximum permissible exposure (MPE) limit. For example, the electronic device can control transmission power based on a SAR limit and / or a power density limit.

[0008] The electronic device can set a transmission power limit for each beam. However, even in the case where each beam satisfies a power density (PD) criterion, when the electronic device performs multi-beam transmission, the total emission of the multiple beams can not satisfy the power density (PD) criterion (e.g., a maximum power emission criterion). Thus, due to multi-beam transmission, the user can be exposed to RF signals exceeding a safety criterion.

[0009] Aspects of the disclosure address at least the above-mentioned problems and / or disadvantages, and provide at least the advantages described below. Aspects of the disclosure will provide a transmission power control method considering a PD criterion during multi-beam transmission and an electronic device thereof.

[0010] Additional aspects will be set forth in part in the description which follows, and, in part, will be apparent from the description, or can be learned by practice of the presented embodiments.

[0011] A mobile electronic device according to aspects of the disclosure is provided. The mobile electronic device includes at least one antenna module including at least one array antenna; a processor operatively connected to the at least one antenna module; and a memory operatively connected to the processor, wherein the memory includes instructions that, when executed, cause the processor to: identify a plurality of beams including a first beam and a second beam for communicating with at least one base station using the at least one antenna module; when the first beam and the second beam correspond to a same first direction, identify a third beam corresponding to a direction different from the first direction and whose received signal strength from the at least one base station is at least a designated value; when identification of the third beam fails, communicate with the at least one base station by applying power backoff of beams corresponding to the same direction to the first beam and the second beam; and when the third beam is identified, change the second beam to the third beam and communicate with the at least one base station using the first beam and the third beam without applying power backoff of beams corresponding to the same direction.

[0012] According to another aspect of the disclosure, a method for multi-beam transmission of a mobile communication device is provided. The method includes identifying a plurality of beams including a first beam and a second beam to be used for transmission, determining whether the first beam and the second beam correspond to a same first direction, when the first beam and the second beam correspond to the same first direction, determining whether a third beam corresponding to a direction different from the first direction and having a received signal strength of at least a specified value exists, when the third beam does not exist, transmitting a signal by applying power backoff of beams corresponding to the same direction to the first beam and the second beam, and when the third beam exists, changing the second beam to the third beam and transmitting a signal without applying power backoff of beams corresponding to the same direction.

[0013] According to another aspect of the disclosure, a mobile electronic device is provided. The mobile electronic device includes a first antenna module including at least one array antenna, a second antenna module including at least one array antenna, a processor operatively connected to the first antenna module and the second antenna module, and a memory operatively connected to the processor, wherein the memory can store instructions that, when executed, cause the processor to form a first beam and a second beam using at least one of the first antenna module or the second antenna module, and when the first beam and the second beam correspond to a same direction, control transmission power associated with the first beam and the second beam based on a relatively lower maximum transmission power compared to single-beam transmission.

[0014] According to various embodiments of the disclosure, an electronic device can minimize the impact of a transmission signal on a human body by controlling transmission power based on a beam direction while maintaining data transmission performance.

[0015] According to various embodiments of the disclosure, an electronic device can provide data transmission satisfying a maximum power emission (MPE) standard by controlling transmission power.

[0059] The communication module 190 can support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 can include one or more communication processors (e.g., an application processor (AP)) that is independent of the processor 120 and is configured to control a wired or wireless communication function of the electronic device 101. According to an embodiment, the communication module 190 can include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with the external electronic device via the first network 198 (e.g., a short-range communication network such as Bluetooth, wireless-fidelity (Wi-Fi), or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These different types of communication modules can be implemented as a single component (e.g., a single chip) or can be implemented as separate components (e.g., separate chips) from each other. The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0060] The antenna module 197 can transmit or receive a signal or power to or from an external electronic device (e.g., an external electronic device) of the electronic device 101.

The signal or the power can then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element can be additionally formed as part of the antenna module 197.

[0061] At least some of the above-described components can be coupled mutually via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicate signals (e.g., commands or data) therebetween.

[0062] According to an embodiment, commands or data can be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199.

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

According to an embodiment, the first communication processor 212 and the second communication processor 214 can be implemented within a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 can be implemented as a system on chip (SoC) or a communication processor (CP). Figure 1 ​The processor 120, the auxiliary processor 123, or the communication module 190 together form a single chip or a single package.

[0072] When performing transmission, the first RFIC 222 converts a baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal of about 700 megahertz (MHz) to about 3 GHz used in the first cellular network 292 (e.g., a legacy network). When performing reception, an RF signal is obtained from the first cellular network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242) and can be pre-processed by an RFFE (e.g., the first RFFE 232). The first RFIC 222 can convert the pre-processed RF signal into a baseband signal so that the signal can be processed by the first communication processor 212.

[0073] When performing transmission, the second RFIC 224 converts a baseband signal generated by the first communication processor 212 or the second communication processor 214 into an 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) (hereinafter referred to as a 5G Sub6 RF signal). When performing reception, a 5G Sub6 RF signal is obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244) and can be pre-processed by an RFFE (e.g., the second RFFE 234). The second RFIC 224 can convert the pre-processed 5G Sub6 RF signal into a baseband signal so that the signal can be processed by a corresponding communication processor among the first communication processor 212 and the second communication processor 214.

[0074] The third RFIC 226 can convert a baseband signal generated by the second communication processor 214 into a 5G Above6 RF signal of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network 294 (e.g., a 5G network). When performing reception, a 5G Above6 RF signal is obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248) and can be pre-processed by the third RFFE 236. For example, the third RFFE 236 pre-processes the signal using a phase shifter 238. The third RFIC 226 can convert the pre-processed 5G Above6 RF signal into a baseband signal so that the signal can be processed by the second communication processor 214. According to another embodiment, the third RFFE 236 can be formed as a part of the third RFIC 226.

[0075] According to another embodiment, the electronic device 101 can include a fourth RFIC 228 separate from or as at least a portion of the third RFIC 226. In this case, the fourth RFIC 228 can convert a baseband signal generated by the second communication processor 214 into an RF signal of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) (hereinafter, referred to as an intermediate frequency (IF) signal), and then can transfer the IF signal to the third RFIC 226. The third RFIC 226 can convert the IF signal into a 5G Above6 RF signal. When performing reception, the 5G Above6 RF signal is received from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248), and can be converted into an IF signal by the third RFIC 226. The fourth RFIC 228 can convert the IF signal into a baseband signal so that the signal can be processed by the second communication processor 214.

[0076] According to another embodiment, the first RFIC 222 and the second RFIC 224 can be implemented as at least a portion of a single chip or a single package. According to another embodiment, the first RFFE 232 and the second RFFE 234 can be implemented as at least a portion of a single chip or a single package. According to another embodiment, at least one of the first antenna module 242 and the second antenna module 244 can not be provided, or can be combined with the other antenna module, in order to process RF signals of a plurality of corresponding frequency bands.

[0077] According to another embodiment, the third RFIC 226 and the antenna 248 can be arranged on the same substrate to form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 can be arranged on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 is arranged in a partial area (e.g., a lower surface) of a second substrate (e.g., a sub-PCB) separate from the first substrate, and the antenna 248 can be arranged in another partial area (e.g., an upper surface) to form the third antenna module 246. According to another embodiment, the antenna 248 can include an antenna array that can be used for beamforming, for example. By arranging the third RFIC 226 and the antenna 248 on the same substrate, the length of a transmission line between the third RFIC 226 and the antenna 248 can be reduced. For example, such a configuration can reduce loss (e.g., attenuation) of a signal of a high frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communication caused by the transmission line. Accordingly, the electronic device 101 can improve the quality or speed of communication with the second cellular network 294 (e.g., a 5G network).

[0078] The second cellular network 294 (e.g., a 5G network) can operate independently of the first cellular network 292 (e.g., a legacy network) (e.g., standalone (SA)) or can operate by connecting to the first cellular network 292 (e.g., non-standalone (NSA)). For example, the 5G network includes only an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NG RAN)) and can not have a core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101 accesses an external network (e.g., the Internet) by being controlled by a core network (e.g., an evolved packet core (EPC)) of a legacy network after accessing the access network of the 5G network. Protocol information (e.g., LTE protocol information) for communication with a legacy network or protocol information (e.g., new radio (NR) protocol information) for communication with a 5G network can be stored in the memory 130 and can be accessed by other components (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

The printed circuit board 310 can provide electrical connections between the printed circuit board 310 and / or various electronic components disposed externally using lines and conductive vias formed in the conductive layers.

As shown, the antenna elements can be formed on a first surface of the printed circuit board 310.

[0084] The RFIC 352 (e.g., the third RFIC 226 of FIG. 2) can be arranged in another region (e.g., a second surface opposite the first surface) of the printed circuit board 310 apart from the antenna array 330. The RFIC 352 can be configured to process signals of a selected frequency band transmitted / received through the antenna array 330. According to an embodiment, when transmission is performed, the RFIC 352 can convert a baseband signal obtained from a communication processor (not shown) into an RF signal of a designated frequency band. When reception is performed, the RFIC 352 can convert an RF signal received via the antenna array 330 into a baseband signal and can transfer the baseband signal to the communication processor. Figure 2 According to another embodiment, when transmission is performed, the RFIC 352 can up-convert an IF signal (e.g., about 9 GHz to about 11 GHz) obtained from an intermediate frequency integrated circuit (IFIC) (e.g., the fourth RFIC 228 of FIG. 2) into an RF signal of a selected frequency band. When reception is performed, the RFIC 352 down-converts an RF signal obtained via the antenna array 330 into an IF signal and can transfer the IF signal to the IFIC.

[0085] Figure 2 The PMIC 354 can be arranged in another partial region (e.g., the second surface) of the printed circuit board 310 apart from the antenna array. The PMIC 354 can be powered by a main PCB (not shown) and can power various components (e.g., the RFIC 352) on the antenna module.

[0086] The shielding member 390 can be arranged on a portion (e.g., the second surface) of the printed circuit board 310 so as to electromagnetically shield at least one of the RFIC 352 or the PMIC 354. According to an embodiment, the shielding member 390 can include a shield can.

[0088] ​Although not shown, in various embodiments, the third antenna module 246 can be electrically connected to another printed circuit board (e.g., a main circuit board) via a module interface. The module interface can include a connection member, such as a coaxial cable connector, a board-to-board connector, an interposer, or a flexible printed circuit board (FPCB). At least one of the RFIC 352 or the PMIC 354 of the third antenna module 246 can be electrically connected to the printed circuit board via the connection member.

[0089] Figure 4 Embodiments of operations of a wireless communication connection between a base station and an electronic device in a second cellular network (e.g., a 5G network) are shown, in accordance with embodiments of the present disclosure, in which directional beams are used for the wireless connection. Figure 2

[0090] Referring to Figure 4 , the base station (gNodeB (gNB), transmission reception point (TRP)) 420 can perform beam detection with the electronic device 101 for the wireless communication connection. In the illustrated embodiment, for the beam detection, the base station 420 can perform a transmission beam sweep 430 at least once by sequentially transmitting a plurality of transmission beams (e.g., first through fifth transmission beams 435-1, 435-2, 435-3, 435-4, 435-5 having different directions).

[0091] The first through fifth transmission beams 435-1 through 435-5 can include at least one synchronization sequence (SS) / physical broadcast channel (PBCH) block. The SS / PBCH block can be used to periodically measure channel or beam strength of the electronic device 101.

[0092] In another embodiment, the first through fifth transmission beams 435-1 through 435-5 can include at least one channel state information reference signal (CSI-RS). The CSI-RS can be a standard / reference signal that can be flexibly configured by the base station 420 and can be transmitted periodically, semi-persistently, or aperiodically. The electronic device 101 can use the CSI-RS to measure channel and beam strength.

[0093] The transmission beams can form a radiation pattern having a selected beam width. For example, the transmission beams can have a wide radiation pattern having a first beam width or a narrow radiation pattern having a second beam width that is smaller than the first beam width. For example, the transmission beams including the SS / PBCH block can have a wider radiation pattern than the transmission beams including the CSI-RS.

[0094] ​When base station 420 is performing transmit beam scan 430, electronic device 101 can perform receive beam scan 440. For example, when base station 420 is performing a first transmit beam scan 435-1 430, electronic device 101 can fix a first receive beam 445-1 in a first direction and can receive signals of at least one SS / PBCH block transmitted from the first transmit beam to the fifth transmit beam 435-1 to 435-5. When base station 420 is performing a second transmit beam scan 435-2 430, electronic device 101 can fix a second receive beam 445-2 in a second direction and can receive signals of SS / PBCH blocks transmitted from the first transmit beam to the fifth transmit beam 435-1 to 435-5. As described above, electronic device 101 can select a communicable receive beam (e.g., the second receive beam 445-2) and a transmit beam (e.g., the third transmit beam 435-3) based on the result of the signal reception operation through receive beam scan 440. Electronic device 101 can also receive signal transmissions on the third receiving beam 445-3.

[0095] As described above, after determining the communicable transmit / receive beams, the base station 420 and electronic device 101 can transmit and / or receive multiple pieces of basic information for configuring the cell, and can configure additional information for beam operation based on the basic information. For example, beam operation information includes detailed information about the configured beams and configuration information about SS / PBCH blocks, CSI-RS, or additional reference signals.

[0096] Furthermore, electronic device 101 can continuously monitor the channel and beam strength using at least one of the SS / PBCH block or CSI-RS included in the transmit beam. Electronic device 101 can adaptively select a beam with good quality using the aforementioned monitoring operation. Optionally, when communication is interrupted due to movement of electronic device 101 or beam interruption, the aforementioned beam scanning operation can be re-executed to determine a communicable beam.

[0097] Figure 5 This is a block diagram illustrating an electronic device for 5G network communication according to an embodiment of the present disclosure.

[0098] Electronic device 101 may include Figure 3 The various components shown are for illustrative purposes only. Figure 5 Electronic device 101 is shown to include processor 120, second communication processor 214, fourth RFIC 228 and at least one third antenna module 246.

[0099] refer to Figure 5The third antenna module 246 can include first to fourth phase converters 513-1, 513-2, 513-3, 513-4 (e.g., phase converters 238 of FIG. 2) and / or first to fourth antenna elements 517-1, 517-2, 517-3, 517-4 (e.g., antennas 248 of FIG. 2). Each of the first to fourth antenna elements 517-1 to 517-4 can be electrically connected to a separate one of the first to fourth phase converters 513-1 to 513-4. The first to fourth antenna elements 517-1 to 517-4 can form at least one antenna array. Figure 2 Figure 2 The first to fourth antenna elements 517-1 to 517-4 can form at least one antenna array.

[0100] The second communication processor 214 can control the phases of signals transmitted and / or received through the first to fourth antenna elements 517-1 to 517-4 by controlling the first to fourth phase converters 513-1 to 513-4, and can generate a transmission beam and / or a reception beam in a corresponding selected direction.

[0101] According to an embodiment, the third antenna module 246 can generate a wide beam 551 (hereinafter referred to as a "wide beam") having a wide radiation pattern or a narrow beam 553 (hereinafter referred to as a "narrow beam") having a narrow radiation pattern according to the number of antenna elements used. For example, when all of the first to fourth antenna elements 517-1 to 517-4 are used, the third antenna module 246 can form the narrow beam 553, and when only the first antenna element 517-1 and the second antenna element 517-2 are used, the third antenna module 246 can form the wide beam 551. The wide beam 551 has a wider coverage than the narrow beam 553, but has a lower antenna gain, and thus can be more efficient in performing a beam search. In contrast, the narrow beam 553 has a narrower coverage than the wide beam 551, but has a higher antenna gain, and thus can improve communication performance.

[0102] According to another embodiment, the second communication processor 214 can use a sensor module 176 (e.g., a 9-axis sensor, a grip sensor, or a GPS) in a beam search. For example, the electronic device 101 uses the sensor module 176 to adjust a beam search position and / or a beam search period based on a position and / or movement of the electronic device 101. For another example, when a user grips the electronic device 101, the grip sensor is used to detect a portion gripped by the user, and an antenna module having better communication performance among a plurality of third antenna modules 246 is selected.

[0103] Figure 6 is a block diagram illustrating an electronic device performing dual-polarized beamforming according to an embodiment of the disclosure.

[0104] ​For the sake of convenience, let's assume... Figure 6 The electronic device 101 includes three antenna modules. However, for electronic devices including fewer or more than three antenna modules, the various embodiments proposed can also be applied as is or with simple design modifications. Furthermore, although... Figure 6 The illustration shows each antenna module forming a beam in two directions, but embodiments of this disclosure are not limited thereto. Each antenna module may form a beam in two or more directions.

[0106] According to an embodiment, during transmission, processor 581 can transmit at least one of the following baseband signals via communication circuit 583: first baseband signals V1, V2, and V3 transmitted via vertically polarized waves and / or second baseband signals H1, H2, and H3 transmitted via horizontally polarized waves to one or more of the first to third antenna modules 601, 602, and 603. For example, communication circuit 583 can up-convert the baseband signals received from processor 581 and transmit the converted baseband signals to one or more of the first to third antenna modules 601, 602, and 603. The first baseband signals V1, V2, and V3 and the second baseband signals H1, H2, and H3 can be the same information or different information.

[0107] According to another embodiment, in a receiving operation, processor 581 can receive baseband signals from one or more of the first antenna module to the third antenna modules 601, 602, and 603 via communication circuit 583. For example, communication circuit 583 can down-convert a signal received from at least one of the first antenna module to the third antenna modules 601, 602, and 603 into a baseband signal, and can transmit the baseband signal to processor 581.

[0108] According to another embodiment, the first to third antenna modules 601, 602, and 603 can include array antennas configured with a plurality of antenna elements. The array antennas can be multi-polarization array antennas. The multi-polarization array antennas can be array antennas capable of transmitting signals based on multi-polarization characteristics. A dual-polarization array antenna, which is one type of multi-polarization array antenna, can support signal transmission / reception through orthogonal polarizations, such as vertical polarization waves and horizontal polarization waves in one beam direction.

[0109] According to another embodiment, the antenna elements included in the multi-polarization array antennas can be patch-type antenna (hereinafter referred to as "patch antenna") elements or dipole-type antenna (hereinafter referred to as "dipole antenna") elements. In the case where the multi-polarization array antennas include patch antenna elements, a plurality of beams having different polarization characteristics in one beam direction are formed in pairs. For example, a dual-polarization array antenna including patch antenna elements forms a beam using vertical polarization characteristics and a beam using horizontal polarization characteristics in one beam direction in pairs.

[0110] According to an embodiment, when a transmission operation is performed, the communication circuit 583 can up-convert the first baseband signal V1 and / or the second baseband signal H1 received from the processor 581 into an intermediate frequency signal, and can transfer the intermediate frequency signal to the first antenna module 601. The first antenna module 601 can transmit the up-converted radio frequency signal through at least one beam of a plurality of beams. According to an embodiment, when a reception operation is performed, the first antenna module 601 can down-convert a radio frequency signal received through at least one beam of a plurality of beams, and can transfer the converted signal to the communication circuit 583. The communication circuit 583 can down-convert the signal received from the first antenna module 601 into a first baseband signal V1 and / or a second baseband signal H1, and then can transfer the converted signal to the processor 581. The plurality of beams can include, for example, a first vertical polarization beam 611 having a vertical polarization characteristic and a first horizontal polarization beam 613 having a horizontal polarization characteristic in a first beam direction, and a second vertical polarization beam 621 having a vertical polarization characteristic and a second horizontal polarization beam 623 having a horizontal polarization characteristic in a second beam direction.

[0111] According to another embodiment, when performing a transmission operation, the communication circuit 583 can up-convert the first baseband signal V2 and / or the second baseband signal H2 received from the processor 581 into an intermediate frequency signal, and can transfer the intermediate frequency signal to the second antenna module 602. The second antenna module 602 can up-convert the intermediate frequency signal into a radio frequency signal, and can transmit the radio frequency signal through at least one of a plurality of beams. According to an embodiment, when performing a reception operation, the second antenna module 602 can down-convert a radio frequency signal received through at least one beam of a plurality of beams into an intermediate frequency signal, and can transfer the intermediate frequency signal to the communication circuit 583. The communication circuit 583 can down-convert the intermediate frequency signal into the first baseband signal V2 and / or the second baseband signal H2, and can transfer the converted signal to the processor 581. The plurality of beams can include, for example, a third vertically polarized beam 631 having a vertically polarized characteristic in a third beam direction and a third horizontally polarized beam 633 having a horizontally polarized characteristic, and a fourth vertically polarized beam 641 having a vertically polarized characteristic in a fourth beam direction and a fourth horizontally polarized beam 643 having a horizontally polarized characteristic.

[0112] According to another embodiment, in a transmission operation, the communication circuit 583 can up-convert the first baseband signal V3 and / or the second baseband signal H3 received from the processor 581 into an intermediate frequency signal, and can transfer the intermediate frequency signal to the third antenna module 603. The third antenna module 603 can up-convert the intermediate frequency signal into a radio frequency signal, and can transmit the radio frequency signal through at least one of a plurality of beams. According to another embodiment, when performing a reception operation, the third antenna module 603 can down-convert a radio frequency signal received through at least one beam of a plurality of beams into an intermediate frequency signal, and can transfer the intermediate frequency signal to the communication circuit 583. The communication circuit 583 can down-convert the intermediate frequency signal into the first baseband signal V3 and / or the second baseband signal H3, and can transfer the converted signal to the processor 581. The plurality of beams can include, for example, a fifth vertically polarized beam 651 having a vertically polarized characteristic in a fifth beam direction and a fifth horizontally polarized beam 653 having a horizontally polarized characteristic, and a sixth vertically polarized beam 661 having a vertically polarized characteristic in a sixth beam direction and a sixth horizontally polarized beam 663 having a horizontally polarized characteristic.

[0113] According to another embodiment, each of the antenna modules 601, 602, and 603 can transmit / receive a wireless signal using a vertically polarized beam and a horizontally polarized beam substantially simultaneously. Because the two polarized waves are orthogonal to each other, the electronic device 101 can increase data throughput or data security using polarization diversity.

[0114] Figure 6The communication circuit 583 is shown, but can not be provided. For example, the processor 581 is directly connected to each of the antenna modules 601, 602, and 603. Each of the antenna modules 601, 602, and 603 can be configured to perform the above-described operations of the communication circuit 583.

[0126] According to another embodiment, the communication circuit 720 can include four path connection circuits 721, 722, 723, and 724, fifth to eighth mixers 725, 726, 727, 728, or a multiplexer and a demultiplexer 729. For example, the four path connection circuits 721, 722, 723, and 724 can electrically connect the fifth to eighth mixers 725, 726, 727, 728 to the first RFIC 730 or the second RFIC 740.

[0130] Various example configurations of the electronic device 101 have been described with reference to Figures 1 to 7 The electronic device 101 of the disclosure can include any combination of the configurations of the electronic device 101 described above with reference to Figures 1 to 7 The operations of the electronic device 101 described below with reference to Figures 8 to 20 may be performed by at least one of the above-described configurations of the electronic device 101.

[0131] Figure 8 A multi-beam transmission using one antenna module according to an embodiment of the disclosure is shown.

[0132] Referring to Figure 8 , the electronic device 801 (e.g., the electronic device 101 of Figures 1 to 7 may include at least one antenna module (e.g., the first antenna module to the third antenna module 601, 602, and 603 of Figure 5 , a communication circuit 890 (e.g., the fourth RFIC 228 of Figure 6 , the communication circuit 583 of Figure 5 , or the communication circuit 720 of Figure 6 ), a processor 820 (e.g., the second communication processor 214 of Figure 7 , and / or the processor 581 of Figure 5 ) operatively connected to the communication circuit 890, and / or a memory 830 (e.g., the memory 130 of Figure 6 ) operatively connected to the processor 820. Figure 1 The configuration of the electronic device 801 of Figure 8 is illustrative, and embodiments of the disclosure are not limited thereto. For example, the memory 830 can not be provided or can be implemented integrally with the processor 820. For example, the communication circuit 890 can not be provided. In this case, at least part of the operations of the communication circuit 890 can be performed by the at least one antenna module 891, 892, and 893.

[0133] For example, the electronic device 801 includes a first antenna module 891, a second antenna module 892, and a third antenna module 893. Each of the antenna modules 891, 892, and 893 can include at least one array antenna (e.g.,Figure 5 The at least one array antenna can include a plurality of antenna elements, which can be arranged at a specified interval in order to perform beamforming. Each antenna element can be referred to as a conductive radiator or a conductive plate. As described above with reference to FIG. 1, each antenna element can be connected to two feed points for dual polarization. Each of the antenna modules 891, 892, and 893 can up-convert a medium frequency signal received from the communication circuit 890 into a radio frequency signal and can transmit (e.g., radiate) the radio frequency signal. Each of the antenna modules 891, 892, and 893 can down-convert a radio frequency signal received from the outside (e.g., a base station) into a medium frequency signal and can transfer the medium frequency signal to the communication circuit 890. Each of the at least one antenna module 891, 892, and 893 can include at least one amplifier for amplifying a signal and / or at least one phase shifter for changing a phase of a signal. The at least one antenna module 891, 892, and 893 can be referred to as a means for beamforming. The means for beamforming can include an antenna device including any antenna capable of performing beamforming, such as the at least one antenna module 891, 892, and 893. Figure 7

[0134] For example, the communication circuit 890 can process a signal received from the at least one antenna module 891, 892, and 893 or the processor 820 and can control an electrical path between the at least one antenna module 891, 892, and 893 and the processor 820. The communication circuit 890 can up-convert a baseband signal (e.g., a vertical polarization signal and / or a horizontal polarization signal) received from the processor 820 into a medium frequency signal and can transfer the medium frequency signal to the at least one antenna module 891, 892, and 893. The communication circuit 890 can receive a medium frequency signal from the at least one antenna module 891, 892, and 893, can down-convert the medium frequency signal into a baseband signal, and can transfer the baseband signal to the processor 820. The communication circuit 890 can include at least one amplifier for amplifying a signal and / or at least one phase shifter for changing a phase of a signal. The communication circuit 890 can be referred to as a means for frequency conversion. The means for frequency conversion can include a device including any RF component capable of performing frequency conversion.

[0135] For example, the processor 820 processes a baseband signal. The processor 820 can modulate and / or demodulate a signal. For example, the processor 820 can be controlled by instructions stored in the memory 830. The operation of the processor 820 can be referred to as an operation of the electronic device 801. The processor 820 can be referred to as a means for signal processing. The means for signal processing can include, for example, any electronic component configured to perform digital and / or analog processing of a signal.

[0136] ​According to another embodiment, the processor 820 can use at least one of the antenna modules 891, 892, and 893 to perform beamforming. The processor 820 can transmit and / or receive a wireless signal using a beam formed by the beamforming. Here, the wireless signal can include a multi-band signal (e.g., a band adjacent to 28 GHz and a band adjacent to 39 GHz) and / or a multi-polarization signal (e.g., a vertically polarized wave and a horizontally polarized wave).

[0137] Referring to Figure 8 For example, the third antenna module 893 is configured to form six beams 841, 842, 843, 844, 845, and 846. The processor 820 can obtain information for generating beams for communication with a first base station 899 (e.g., a gNB) from a beam table stored in the memory 830. For example, the beam table includes a beam index and beamforming information (e.g., antenna module, polarization, and / or phase information) mapped to the index.

[0138] Referring to Figure 8 The processor 820 can communicate with the first base station 899 using the 3-1st beam 841 and the 3-6th beam 846. For example, the processor 820 transmits at least one wireless signal to the first base station 899 using the 3-1st beam 841 and the 3-6th beam 846. For example, the 3-1st beam 841 corresponds to a line of sight (LoS) between the electronic device 801 and the first base station 899, and the 3-6th beam 846 can correspond to a wireless path formed by signal reflection between the first base station 899 and the electronic device 801.

[0139] The processor 820 can form beams such that two beams have different frequency bands. For example, the processor 820 can differently configure the frequency bands of the 3-1st beam 841 and the 3-6th beam 846. In an example, the 3-1st beam 841 can be used to transmit / receive a signal of a first frequency band (e.g., a band adjacent to 39 GHz), and the 3-6th beam 846 can be used to transmit / receive a signal of a second frequency band (e.g., a band adjacent to 28 GHz).

[0140] The processor 820 can form beams such that two beams have characteristics orthogonal to each other. For example, the processor 820 differently configures the polarizations of the 3-1st beam 841 and the 3-6th beam 846. The 3-1st beam 841 can correspond to a horizontally polarized wave, and the 3-6th beam 846 can correspond to a vertically polarized wave. For example, the processor 820 can configure the frequency bands of the 3-1st beam 841 and the 3-6th beam 846 to be the same frequency band or adjacent frequency bands.

[0141] The processor 820 can differently configure the frequency bands and polarizations of the 3-1st beam 841 and the 3-6th beam 846.

[0142] Referring to Figure 8 , a first signal using the 3-1 beam 841 can be associated with a first cell (e.g., a primary cell) of the first base station 899, and a second signal using the 3-6 beam 846 can be associated with a second cell (e.g., a secondary cell) of the first base station 899.

[0143] According to another embodiment, the processor 820 can increase the amount of data transmission using spatial multiplexing based on multi-beam transmission. For example, the processor 820 performs carrier aggregation (CA) through multi-beam transmission. The processor 820 can increase the bandwidth of a wireless signal by performing carrier aggregation using a first frequency band of the 3-1 beam 841 and a second frequency band of the 3-6 beam 846. For example, the processor 820 transmits a first signal including first data to the first base station 899 using the 3-1 beam 841, and transmits a second signal including second data different from the first data to the first base station 899 using the 3-6 beam 846. The first frequency band of the 3-1 beam 841 and the second frequency band of the 3-6 beam 846 can be different frequency bands.

[0144] According to another embodiment, the processor 820 can reduce data transmission errors using spatial diversity based on multi-beam transmission. For example, the processor 820 performs a multiple-input multiple-output (MIMO) operation through multi-beam transmission. The processor 820 can transmit a first signal including first data to the first base station 899 using the 3-1 beam 841, and can transmit a second signal including the first data to the first base station 899 using the 3-6 beam 846. The first base station 899 can increase the decoding success rate of a received signal by combining the first signal and the second signal. Although Figure 8 It is shown that the electronic device 801 performs a MIMO operation with respect to the first base station 899, but embodiments of the disclosure are not limited thereto. For example, as described below with reference to Figure 9 , the electronic device 801 performs a MIMO operation with respect to a plurality of base stations (e.g., the first base station 899 and the second base station 999). For example, the electronic device 801 performs a MIMO operation by forming a plurality of beams using one antenna module and transmitting signals to a plurality of base stations using the plurality of beams.

[0145] Hereinafter, descriptions of the same reference numerals can refer to the above description provided with reference to Figure 8 the accompanying drawings, unless otherwise specified.

[0146] Figure 9 It is shown that multi-beam transmission using a plurality of antenna modules according to an embodiment of the disclosure.

[0147] Referring to Figure 9The processor 820 can communicate with the first base station 899 using the 3-3 beam 843 and can communicate with the second base station 999 using the first beam 944. For example, the processor 820 transmits a first signal to the first base station 899 using the 3-3 beam 843 and transmits a second signal to the second base station 999 using the first beam 944. The processor 820 can form the first beam 944 using the first antenna module 891 and can form the 3-3 beam 843 using the third antenna module 893. For example, the processor 820 transmits / receives a signal of a first frequency band (e.g., a frequency band adjacent to 39 GHz) using the first beam 944 and can transmit / receive a signal of a second frequency band (e.g., a frequency band adjacent to 39 GHz) using the 3-3 beam 843. For example, the processor 820 can configure the frequency bands of the first beam 944 and the 3-3 beam 843 as adjacent frequency bands (e.g., 28.2 GHz and 28.4 GHz). For example, the processor 820 can differently configure polarizations of the first beam 944 and the 3-3 beam 843.

[0148] Referring to Figure 9 The first beam 944 can be associated with a second cell of the second base station 999, and the 3-3 beam 843 can be associated with a first cell of the first base station 899. For example, the first cell can be a P-Cell associated with the electronic device 801, and the second cell can be an S-Cell associated with the electronic device 801.

[0149] According to another embodiment, the processor 820 can increase the amount of data transmission using spatial multiplexing based on multi-beam transmission. The processor 820 can transmit a first signal of a first frequency band using the first beam 944 and can transmit a second signal of a second frequency band using the 3-3 beam 843. For example, the first base station 899 and the second base station 999 exchange data by using an inter-base station connection (e.g., a backhaul link), thereby increasing data throughput from the electronic device 801.

[0150] According to another embodiment, the processor 820 can reduce data transmission error using spatial diversity based on multi-beam transmission. For example, the processor 820 transmits a first signal including first data to the second base station 999 using the first beam 944 and can transmit a second signal including the first data to the first base station 899 using the 3-3 beam 843.

[0151] Regarding Figure 9Examples have been described whereby processor 820 communicates with a first base station 899 using a third-third beam 843 and with a second base station 999 using a first beam 944, but embodiments of this disclosure are not limited thereto. For example, processor 820 may use both the first beam 944 and the third-third beam 843 to communicate with the first base station 899. For instance, the third-third beam 843 may correspond to the line-of-sight (LoS) between the first base station 899 and the electronic device 801, while the first beam 944 may correspond to the propagation path between the electronic device 801 and the first base station 899 caused by any reflector. According to another embodiment, processor 820 may use the first beam 944 and the third-third beam 843 to perform carrier aggregation with the first base station 899. The third-third beam 843 may be associated with a P-cell of the first base station 899, while the first beam 944 may be associated with an S-cell of the first base station 899. According to another embodiment, the processor 820 can use the first beam 944 and the third-third beam 843 to perform MIMO operation, orthogonal polarization transmission, or spatial multiplexing with the first base station 899. In this case, the first beam 944 and the third-third beam 843 can be associated with the same cell.

[0152] Figure 10 Multi-polarization-based multi-beam transmission according to an embodiment of this disclosure is illustrated.

[0153] refer to Figure 10 The processor 820 can communicate with the first base station 899 using the first beam 1041 and the second beam 1043. For example, the processor 820 can send a first signal to the first base station 899 using the first beam 1041 and can send a second signal to the first base station 899 using the second beam 1043. Figure 10 In the example, the first beam 1041 and the second beam 1043 can be beams formed in the same direction but with different polarizations. (See above reference.) Figure 8 and Figure 9 The processor 820 can use two beams 1041 and 1043 to achieve spatial multiplexing or spatial diversity.

[0154] Already referenced Figures 8 to 10 Various examples of multi-beam transmission in electronic device 801 are described. Electronic device 801 can control the transmission power based on equivalent isotropic radiated power (EIRP). Figure 9 In the case of multi-beam transmission, the transmitting beam of electronic device 801 is oriented in different directions, and the effect of multi-beam transmission on the human body can be similar to that of single-beam transmission. However, in Figure 8 and Figure 10In the case of multi-beam transmission, EIRP may increase because multiple beams are directed in similar directions. For example, electronic device 801, according to reference later... Figures 11 to 16 Various methods are described to control transmission power such that the power density resulting from the transmission of wireless signals meets reference specifications. When performing multi-beam transmission, if multiple beams are directed in the same direction, the electronic device 801 can reduce power compared to single-beam transmission. For example, if multi-beam transmission is directed in the same direction, the electronic device 801 performs (additional) power back-off compared to single-beam transmission.

[0155] Figure 11 This is a flowchart illustrating a wireless signal transmission method according to an embodiment of the present disclosure.

[0156] refer to Figure 11 In method 1100, in operation 1105, electronic device 801 can identify multiple transmission beams. For example, electronic device 801 can refer to the above-mentioned reference. Figure 4 The described beam scanning is used to identify multiple transmit beams used for communication with at least one base station. For example, when receiving information from the base station indicating the use of multiple transmit beams for uplink transmission, electronic device 801 can identify the multiple transmit beams.

[0157] In operation 1110, electronic device 801 can determine whether multiple beams correspond to the same direction. For example, electronic device 801 determines whether multiple identified beams correspond to beam combinations specified in a memory. The memory of electronic device 801 can store information about beam combinations corresponding to the same direction (e.g., beam index combinations). Electronic device 801 can determine whether multiple identified beams correspond to the same direction by comparing the index information of multiple identified beams with the information about beam combinations. The beam combination identification method of electronic device 801 is illustrative, and embodiments of this disclosure are not limited thereto. Furthermore, the meaning of "beams corresponding to the same direction" can be defined based on the direction in which the beam is formed relative to electronic device 801 (e.g., the main lobe of the beam). Reference can be made to... Figure 12 Describe in detail the meaning of "beams corresponding to the same direction".

[0158] When a plurality of beams correspond to the same direction (for example, operation 1110 - Yes), the electronic device 801 can perform power backoff based on beam combining in operation 1115. For example, the electronic device 801 can perform a relative power backoff compared to single-beam transmission. In operation 1120, the electronic device 801 can transmit a wireless signal using a plurality of beams. In the case where a plurality of beams correspond to the same direction, the electronic device 801 can transmit a signal based on a maximum transmission power (for example, a transmission power on which power backoff has been performed) that is lower than a set maximum transmission power compared to single-beam transmission. For example, a transmission power set for a plurality of beams is determined within a range of a maximum transmission power to which power backoff is applied. In contrast, in the case of single-beam transmission, a transmission power is determined within a maximum transmission power that is higher than in the case of multi-beam transmission.

[0159] For example, a maximum transmission power of single-beam transmission is set to a first transmission power. When no other power backoff is performed, the electronic device 801 can apply power backoff for multi-beam transmission to the first transmission power (for example, operation 1115) to set a second transmission power that is lower than the first transmission power as a maximum transmission power of multi-beam transmission.

[0160] According to another embodiment, the electronic device 801 can perform power backoff on a maximum transmission power based on a designated condition (for example, detection of a neighboring user or detection of a user adjacent to a beam direction). In this case, the electronic device 801 can set a maximum transmission power of single-beam transmission to a third transmission power (for example, a power lower than the first transmission power). When the designated condition is satisfied, the electronic device 801 can apply power backoff for multi-beam transmission to the third transmission power (for example, operation 1115) to set a fifth transmission power that is lower than the third transmission power as a maximum transmission power of multi-beam transmission.

[0161] In the disclosure, power backoff for multi-beam transmission can be combined with another type of backoff that can be performed by the electronic device 801, and can be referred to as a relative or additional backoff for single-beam transmission. Embodiments of the disclosure do not exclude another type of backoff (for example, a backoff based on detection of a neighboring object) for transmission power.

[0162] The description of transmitting a wireless signal using a plurality of beams can refer to the description provided in the reference Figures 8 to 10 In the disclosure, a backoff in multi-beam transmission can be referred to as a transmission power backoff with respect to a maximum transmission power of single-beam transmission. Regarding a backoff of transmission power for a plurality of beams corresponding to the same direction, reference can be made to the description below in relation to Figure 14 and Figure 15 .

[0163] When multiple beams do not correspond to the same direction (e.g., operation 1110-No), electronic device 801 can use multiple beams to transmit wireless signals. For example, electronic device 801 can set the transmission power of each of the multiple beams within a range of maximum transmission power, which is substantially the same as the maximum transmission power set for single-beam transmission. A description of using multiple beams to transmit wireless signals can be found in [reference needed]. Figures 8 to 10 The above description provides further information regarding signal transmission using multiple beams that do not correspond to the same direction. For more information, please refer to [the relevant documentation / reference]. Figure 13 The following description is relevant.

[0164] Figure 12 Multiple beams corresponding to the same direction are shown according to an example of this disclosure.

[0165] For example, beams formed in the same direction by the same antenna modules (such as...) Figure 10 The first beam 1041 and the second beam 1043 can correspond to the same direction. Since a handheld device, such as electronic device 801, is used near the user, all beams that can be formed by the same antenna module can be said to correspond to the same direction. For example, with... Figure 8 All beams in beams 841, 842, 843, 844, 845, and 846 associated with the third antenna module 893 can be referred to as beams corresponding to the same direction. For example, when using with Figure 8 The third antenna module 893 is associated with beams 841, 842, 843, 844, 845, and 846 directed to the same base station (e.g., Figure 8 When the first base station 899 transmits the first signal or the second signal, beams 841, 842, 843, 844, 845, and 846 may be referred to as beams corresponding to the same direction. For another example, only portions of the beams associated with the same antenna module are referred to as beams corresponding to the same direction. Figure 8 The 3-1 beam 841 and 3-6 beam 846 of the third antenna module 893 can be referred to as beams corresponding to the same direction. Furthermore, see the following reference... Figure 12 The multiple beams associated with different antenna modules can also be referred to as beams corresponding to the same direction.

[0166] In the disclosure, a plurality of beams corresponding to the same direction can be determined based on a PD criterion. For example, it can be determined whether a plurality of beams correspond to the same direction based on an amount of transmission power incident on a plane of a specified region S formed at a specified distance d from the electronic device 801. For example, it is assumed that each of the plurality of beams is transmitted with the maximum transmission power of a single-beam transmission. In this case, when the amount of transmission power of the plurality of beams observed on an arbitrary plane of the specified region S located at the specified distance d exceeds a specified value, the plurality of beams can be considered to correspond to the same direction.

[0167] Referring to Figure 12 , the electronic device 801 can transmit a signal using a first beam 1291 associated with the third antenna module 893 and a second beam 1292 associated with the second antenna module 892. For example, the main lobe of the first beam 1291 and the second beam 1292 is incident on an arbitrary plane of the specified distance d. In this case, the transmission power observed by the first beam 1291 and the second beam 1292 can not satisfy the power density (PD) criterion. The first beam 1291 and the second beam 1292 can be referred to as beams corresponding to the same direction.

[0168] According to another embodiment, the memory 830 of the electronic device 801 can store information about a combination of beams corresponding to the same direction. The processor 820 can identify whether a plurality of beams correspond to the same direction using the information about the plurality of beams for transmission stored in the memory 830 and the information about the combination corresponding to the same direction.

[0169] According to another embodiment, the memory 830 of the electronic device 801 can store direction information and an index of a plurality of beams. If the direction information about the plurality of beams for transmission is the same, the processor 820 can determine that the plurality of beams correspond to the same direction. Table 1 illustrates beam information stored in the memory 830 according to an example.

[0170] Table 1

[0171]

[0172] For example, the first number (1 or 2) of the beam identifier can represent a frequency band associated with the beam. The second identifier (A to F) of the beam identifier can be set according to the direction of each beam. For example, Table 1 includes the electronic device in a state of forming a specified region S as illustrated in FIG. 8A. In this case, the first beam 1291 and the second beam 1292 can be considered to correspond to the same direction. Figure 6The six directions shown are beam identifiers at the time of beam forming. The third identifier of the beam identifier can indicate a direction. For example, L indicates that a beam is formed in a left direction with respect to the electronic device 801, U indicates that a beam is formed in an up direction with respect to the electronic device 801, and R indicates that a beam is formed in a right direction with respect to the electronic device 801. When the identifiers of the plurality of identified beams are 1-A-L and 2-B-L, the electronic device 801 can determine that the two beams correspond to the same direction. Although the beam identifier includes direction information in Table 1, embodiments of the disclosure are not limited thereto. For example, direction information mapped to the beam identifier can be stored separately.

[0173] For example, the first number (1 or 2) of the beam identifier indicates a polarization associated with a beam. For example, the first number 1 can indicate that a beam is formed as a vertically polarized wave, and the first number 2 can indicate that a beam is formed as a horizontally polarized wave.

[0174] With regard to the above-described example, it has been described that the electronic device 801 identifies beams corresponding to the same direction using values stored in the memory 830, but embodiments of the disclosure are not limited thereto. For example, the electronic device 801 dynamically determines whether a plurality of beams correspond to the same direction based on various criteria described above with reference to Figure 12

[0175] Figure 13 A multi-beam transmission based on a first threshold according to an embodiment of the disclosure is illustrated.

[0176] Referring to Figure 13 , the processor 820 can perform a multi-beam transmission using a first beam 1391 and a second beam 1392. The first beam 1391 and the second beam 1392 can correspond to different directions (for example, Figure 11 of operation 1110-NO). In this case, the electronic device 801 can perform a multi-beam transmission without performing an additional power backoff associated with the multi-beam transmission. As described above with reference to Figure 11 , the electronic device 801 can perform an additional power backoff (for example, a power backoff based on detection of an external object) based on a specified condition for at least one of the first beam 1391 or the second beam 1392. For example, the electronic device 801 determines a transmission power of each of the first beam 1391 and the second beam 1392 within a range of a first threshold Th1. The first threshold Th1 is a maximum transmission power set for a single-beam transmission power, and can vary according to whether a wireless signal of less than 6 GHz is simultaneously transmitted. That is, the electronic device 801 can control the transmission power of each of the first beam 1391 and the second beam 1392 in substantially the same manner as in the case of a single-beam transmission.

[0177] ​The first threshold Th1 can be a maximum transmission power set for each beam when the electronic device 801 cannot detect an external object (e.g., a human body). For example, when the electronic device 801 is located in free space, the electronic device 801 performs multi-beam transmission based on the first threshold Th1.

[0178] According to another embodiment, if a specified condition is satisfied (e.g., a neighboring user is detected or a user adjacent to a beam direction is detected), the electronic device 801 can perform power backoff on the first threshold Th1. Hereinafter, for convenience, the first threshold Th1 can be referred to as a maximum transmission power set for single-beam transmission. As described above, the maximum transmission power can be a value obtained by power backoff according to a specified condition or a value in free space. In the following example, the first threshold Th1 is a relative value, not a specific absolute value. As described above, the maximum transmission power for single-beam transmission can change according to a specific condition.

[0179] Figure 14 A multi-beam transmission based on a second threshold according to an embodiment of the disclosure is illustrated.

[0180] Referring to Figure 14 , the processor 820 can perform multi-beam transmission using the first beam 1491 and the second beam 1492. The first beam 1491 and the second beam 1492 can correspond to the same direction (e.g., Figure 11 of operation 1110- is). In this case, the electronic device 801 can perform additional power backoff associated with multi-beam transmission (e.g., Figure 11 of operation 1115). For example, the electronic device 801 determines the transmission power of each of the first beam 1491 and the second beam 1492 within a range of a second threshold Th2. The second threshold Th2 can be a value smaller than the first threshold Th1 set for single-beam transmission power. For example, the second threshold Th2 corresponds to a maximum transmission power that is backed off by a specified value from the first threshold Th1. That is, the electronic device 801 can control the transmission power of each of the first beam 1491 and the second beam 1492 based on a maximum transmission power lower than the maximum transmission power for single-beam transmission.

[0181] As described above with reference to Figure 11 , the electronic device 801 can perform additional power backoff (e.g., power backoff based on detection of an external object) based on a specified condition for at least one of the first beam 1491 or the second beam 1492. For example, as described above with reference to Figure 11The first threshold Th1 is a relative value and can change. As the first threshold changes, the second threshold Th2 can also change. According to an embodiment, the electronic device 801 can perform an additional power back-off on the first threshold Th1 and / or the second threshold Th2 if a specified condition is met (e.g., a neighboring user is detected or a user adjacent to the beam direction is detected).

[0182] The power control method described above with reference to Figure 14 is illustrative, and embodiments of the disclosure are not limited thereto. Figure 14 Examples of the above-described power control method are used to describe the use of a relatively lower maximum transmission power in multi-beam transmission using multiple beams corresponding to the same direction. Figure 14 A specific maximum transmission power value or back-off method is not limited. For example, the electronic device 801 can be configured to perform various back-off methods as described below with reference to Figure 15 .

[0183] Figure 15 A multi-beam transmission based on a second threshold and a third threshold according to an embodiment of the disclosure is shown.

[0184] With reference to Figure 15 , the processor 820 can perform multi-beam transmission using a first beam 1591 and a second beam 1592. The first beam 1591 and the second beam 1592 can correspond to the same direction (e.g., Figure 11 Operation 1110- of the above-described method). In this case, the electronic device 801 can perform an additional power back-off associated with multi-beam transmission (e.g., Figure 11 Operation 1115 of the above-described method). According to an embodiment, the electronic device 801 can apply different amounts of power back-off to multiple beams corresponding to the same direction. For example, the electronic device 801 determines the transmission power of each of the first beam 1591 and the second beam 1592 within the range of the second threshold Th2 and the range of the third threshold Th3. The second threshold Th2 can be a value smaller than the first threshold Th1 set for single-beam transmission power. The third threshold Th3 can be a value smaller than the second threshold Th2. For example, the second threshold Th2 can correspond to a maximum transmission power back-off by a first specified value from the first threshold Th1, and the third threshold Th3 can correspond to a maximum transmission power back-off by a second specified value from the second threshold Th2. For example, as described above with reference to Figure 13 The first threshold Th1 is a relative value and can change. As the first threshold changes, the second threshold Th2 and the third threshold Th3 can also change.

[0185] According to another embodiment, the electronic device 801 can apply different amounts of power backoff based on a type of cell associated with the multiple beams. For example, the electronic device 801 applies a greater amount of power backoff to beams associated with an S-Cell than to beams associated with a P-Cell. In this case, the electronic device 801 can control the transmission power with respect to a first beam 1591 associated with a P-Cell based on a second threshold Th2, and can control the transmission power with respect to a second beam 1592 associated with an S-Cell based on a third threshold Th3. For another example, the electronic device 801 applies a smaller amount of power backoff to beams associated with an S-Cell than to beams associated with a P-Cell. In this case, the electronic device 801 can control the transmission power with respect to a first beam 1591 associated with an S-Cell based on a second threshold Th2, and can control the transmission power with respect to a second beam 1592 associated with a P-Cell based on a third threshold Th3.

[0186] According to another embodiment, the electronic device 801 can apply different amounts of power backoff based on a frequency band associated with the multiple beams. For example, the electronic device 801 applies a greater amount of power backoff to beams associated with a second frequency band than to beams associated with a first frequency band. For example, in an example of FIG. 15, Figure 15 The first beam 1591 can be associated with a second frequency band (e.g., a frequency band of at least 30 GHz), and the second beam 1592 can be associated with a first frequency band (e.g., a frequency of at least 6 GHz and less than 30 GHz). In this case, the electronic device 801 can control the transmission power with respect to the first beam 1591 based on a second threshold Th2, and can control the transmission power with respect to the second beam 1592 based on a third threshold Th3. For example, the electronic device 801 applies a higher transmission power to a relatively higher frequency band in consideration of path loss. For another example, the electronic device 801 applies a lower transmission power to a relatively higher frequency band in consideration of an impact on a human body.

[0187] As described above with reference to Figure 11 As described above with reference to Figure 11 The first threshold Th1 is a relative value and can change. As the first threshold changes, the second threshold Th2 can also change. According to another embodiment, if a specified condition (e.g., detection of a neighboring user or detection of a user adjacent to a beam direction) is satisfied, the electronic device 801 can perform additional power backoff with respect to the first threshold Th1 and / or the second threshold Th2.

[0188] According to another embodiment, the electronic device 801 can apply different amounts of power backoff based on an amount of uplink resources associated with multiple beams. For example, the electronic device 801 applies a relatively small power backoff to beams for which a relatively large amount of radio resources is allocated (e.g., beams for which a relatively large number of resource blocks is allocated). For example, in the example of FIG. 15A, the electronic device 801 can apply a power backoff of 3 dB to the first beam 1591 and a power backoff of 1 dB to the second beam 1592. Figure 15 In the example of FIG. 15A, the amount of uplink resources associated with the first beam 1591 can be greater than the amount of uplink resources associated with the second beam 1592. In this case, the electronic device 801 can control the transmission power with respect to the first beam 1591 based on the second threshold Th2 and can control the transmission power with respect to the second beam 1592 based on the third threshold Th3.

[0189] According to another embodiment, the electronic device 801 can apply different amounts of power backoff based on polarization characteristics associated with multiple beams. For example, the electronic device 801 applies a larger amount of power backoff to beams associated with vertically polarized waves than to beams associated with horizontally polarized waves.

[0190] According to another embodiment, the electronic device 801 can apply different amounts of power backoff based on characteristics of antenna elements associated with multiple beams. For example, the electronic device 801 applies a larger amount of power backoff to beams associated with dipole antennas than to beams associated with patch antennas.

[0191] According to another embodiment, the electronic device 801 can perform power backoff using values stored in the memory 830. For example, the memory 830 stores a first backoff value corresponding to a difference between the first threshold Th1 and the second threshold Th2. The memory 830 can store a second backoff value corresponding to a difference between the second threshold Th2 and the third threshold Th3 or a difference between the first threshold Th1 and the third threshold Th3. For example, the second threshold Th2 can correspond to 21 dBm and the third threshold Th3 can correspond to 19 dBm.

[0192] The electronic device 801 can obtain a backoff value to be applied to multi-beam transmission using multiple beams corresponding to the same direction from the memory 830. For example, the memory 830 stores a beam combination and information about a backoff value mapped to the beam combination. For example, the electronic device 801 uses the identified beam combination and information about the backoff value stored in the memory to perform backoff for each beam. For another example, the electronic device 801 determines a backoff value to be applied to each beam according to the above-described examples (e.g., frequency band and / or associated cell type).

[0193] Figure 16 FIG. 16 is a flowchart illustrating a method of controlling transmission power according to an embodiment of the disclosure.

[0194] Reference Figure 16 In the method 1600, in operation 1605, the processor 820 of the electronic device 801 can identify a plurality of transmission beams (e.g., Figure 11 of operation 1105). For example, the processor 820 performs operation 1605 when there is data to be transmitted, when an uplink grant is received, or when beam sweeping is performed. For another example, the processor 820 performs operation 1605 based on a user input or a designated interval.

[0195] In operation 1610, the processor 820 can determine whether the plurality of beams correspond to the same direction. For example, as described above with reference to Figure 11 of operation 1110, the processor 820 determines whether the plurality of beams correspond to the same direction based on various methods. The definition of the plurality of beams corresponding to the same direction is the same as described above with reference to Figure 12 .

[0196] When the plurality of beams correspond to the same direction (e.g., operation 1610-Yes), in operation 1615, the processor 820 can perform a second type or a third type of transmission power control. For example, the second type of transmission power control is referred to as performing the same power backoff for the plurality of beams, as described above with reference to Figure 14 . For example, the third type of transmission power control is referred to as performing different power backoff for the plurality of beams, as described above with reference to Figure 15 .

[0197] For example, the processor 820 is configured to perform the second type of transmission power control or the third type of transmission power control based on a combination of the plurality of beams. The processor 820 can be configured to apply the second type of transmission power control to a combination of designated beams and to apply the third type of transmission power control to a combination of other beams. For another example, the processor 820 is configured to apply only the second type of transmission power control. For another example, the processor 820 is configured to apply only the third type of transmission power control.

[0198] When the plurality of beams do not correspond to the same direction (e.g., operation 1610-No), in operation 1620, the processor 820 can perform a first type of transmission power control. For example, the first type of transmission power control indicates that no additional power backoff is performed for multi-beam transmission, as described above with reference to Figure 13 .

[0199] The processor 820 can perform multi-beam transmission while performing the transmission power control determined according to the flowchart 1600. For example, as described above with reference to Figure 16 , the processor 820 can achieve spatial multiplexing or spatial diversity through multi-beam transmission. Figures 8 to 10 ​

[0200] Figure 17 FIG. 17 is a flowchart illustrating a transmission power control method according to the embodiment.

[0201] Referring to Figure 17 In the method 1700, in operation 1705, the processor 820 of the electronic device 801 can identify a plurality of transmission beams (e.g., Figure 11 of operation 1105). For example, the processor 820 performs operation 1705 when there is data to be transmitted, when an uplink grant is received, or when beam sweeping is performed. For another example, the processor 820 performs operation 1705 based on a user input or a designated interval.

[0202] In operation 1710, the processor 820 can determine whether the plurality of beams correspond to the same direction. For example, as described above with reference to operation 1110 of Figure 11 , the processor 820 determines whether the plurality of beams correspond to the same direction based on various methods. The definition of the plurality of beams corresponding to the same direction is the same as described above with reference to Figure 12 .

[0203] When the plurality of beams correspond to the same direction (e.g., operation 1710-YES), in operation 1715, the processor 820 determines whether an external object is detected in the direction of the plurality of beams. For example, the processor 820 identifies a relative position (e.g., a direction and / or a distance) of the external object with respect to the electronic device and / or a type of the external object. For example, the processor 820 detects the direction and / or the type of the external object using a proximity sensor, a grip sensor, and / or a component for transmitting / receiving radio waves. For example, the processor 820 identifies the position and the type of the external object by transmitting a signal and receiving a reflected wave using the antenna modules (e.g., the antenna modules 891, 892, and 893 of Figure 8 ). The processor 820 can identify the position and the type of the external object by comparing the phases and amplitudes between the transmitted signal and the received signal.

[0204] When the multiple beams do not correspond to the same direction (e.g., operation 1710 - No), the processor 820 can perform a first type of transmission power control in operation 1720. For example, the first type of transmission power control indicates that no additional power backoff is performed for the multi-beam transmission. In the case of the first type of transmission power control, the processor 820 can perform power backoff for each of the transmission beams based on the external object. For example, the multiple beams include a first beam toward a first direction and a second beam toward a second direction. When an external object (e.g., a human body) is detected in the first direction but no external object is detected in the second direction, the processor 820 can perform power backoff for the first beam based on the first beam and can not perform additional power backoff for the second beam.

[0205] When an external object is detected in the direction of the multiple beams (e.g., operation 1715 - Yes), the processor 820 performs a second type or a third type of transmission power control in operation 1725. The second type of transmission power control and the third type of transmission power control can be referred to as transmission power control for applying additional backoff for the multi-beam transmission. For example, the second type of transmission power control is referred to as performing the same power backoff for the multiple beams, as described above with reference to Figure 14 For example, the third type of transmission power control is referred to as performing different power backoff for the multiple beams, as described above with reference to Figure 15 For example, the third type of transmission power control is referred to as performing different power backoff for the multiple beams, as described above with reference to

[0206] For example, the processor 820 is configured to perform the second type of transmission power control or the third type of transmission power control based on a combination of the multiple beams. The processor 820 can be configured to apply the second type of transmission power control to a combination of designated beams and to apply the third type of transmission power control to a combination of other beams. For another example, the processor 820 is configured to apply only the second type of transmission power control. For another example, the processor 820 can be configured to apply only the third type of transmission power control.

[0207] When no external object is detected in the direction of the multiple beams (e.g., operation 1715 - No), the processor 820 can perform the first type of transmission power control in operation 1720. For example, the first type of transmission power control indicates that no additional power backoff is performed for the multi-beam transmission. Since no external object is detected in the direction of the multiple beams, the processor 820 can transmit a signal without performing power backoff based on the external object.

[0208] The processor 820 can perform the multi-beam transmission while performing the transmission power control determined according to the flowchart 1700 of Figure 17 For example, as described above with reference to Figures 8 to 10 The processor 820 achieves spatial multiplexing or spatial diversity through the multi-beam transmission.

[0209] Figure 18 is a flowchart illustrating a transmission power control method according to an embodiment of the disclosure.

[0210] According to an embodiment, in operation 1805, the processor 820 of the electronic device 801 can identify a plurality of transmission beams (e.g., Figure 11 of operation 1105).

[0211] Referring to Figure 18 , in the method 1800, in operation 1810, the processor 820 can determine whether an external object is detected. When an object adjacent to the electronic device 801 is detected, the processor 820 can determine that the external object has been detected. When an external object is detected in a direction corresponding to at least one of the plurality of beams, the processor 820 can determine that the external object has been detected. When no adjacent object is detected, or when no external object is detected in a direction corresponding to the plurality of beams, the processor 820 can determine that the external object has not been detected.

[0212] When no external object is detected (e.g., operation 1810 - No), in operation 1820, the processor 820 can not apply a backoff to the transmission power of the plurality of beams. For example, it is assumed that the electronic device 801 is located in a free space.

[0213] When an external object is detected (e.g., operation 1810 - Yes), in operation 1815, the processor 820 can determine whether the plurality of beams correspond to the same direction. For example, as described above with reference to operation 1110 of Figure 11 , the processor 820 determines whether the plurality of beams correspond to the same direction based on various methods. The definition of the plurality of beams corresponding to the same direction is the same as described above with reference to Figure 12 .

[0214] When the plurality of beams correspond to the same direction (e.g., operation 1815 - Yes), in operation 1825, the processor 820 can apply a first power backoff and / or a second power backoff to the plurality of beams. For example, when the same level of backoff is applied as described above with reference to Figure 14 , the first power backoff is applied to the plurality of beams. For example, when different levels of backoff are applied as described above with reference to Figure 15 , the first power backoff is applied to a first beam of the plurality of beams, and the second power backoff can be applied to a second beam of the plurality of beams.

[0215] When the multiple beams do not correspond to the same direction (for example, operation 1815 - No), in operation 1830, the processor 820 can apply a third power backoff and / or a fourth power backoff. For example, each of the third power backoff and the fourth power backoff is a smaller value than the first power backoff and the second power backoff. In operation 1825, since the multiple beams correspond to the same direction, the processor 820 can apply a relatively large value of the power backoff compared to operation 1830. For example, the third power backoff is applied to the multiple beams. For example, the third power backoff is applied to a first beam of the multiple beams, and the fourth power backoff can be applied to a second beam of the multiple beams. For example, the third power backoff is applied only to a beam of the multiple beams corresponding to a direction in which the external object has been detected, and a relatively small fourth power backoff can be applied to a beam in a direction in which the external object has not been detected.

[0216] Figure 19 A transmission beam management of an electronic device according to an embodiment of the disclosure is illustrated.

[0217] According to an embodiment, when multiple transmission beams are used, the electronic device 801 can control the transmission beams so as not to correspond to the same direction. For example, when the multiple transmission beams correspond to the same direction, the electronic device 801 determines whether there is a beam satisfying a specified condition among the beams not corresponding to the same direction and the multiple transmission beams. For example, a received signal strength (for example, a reference signal received power) of the beam is at least a specified value, and it is determined that the beam is a beam corresponding to the specified condition. In this case, the electronic device 801 can change at least one of the multiple transmission beams with respect to the beam satisfying the specified condition. The electronic device 801 can control the multiple transmission beams by changing the beam so as not to correspond to the same direction. Through the transmission beam control, the electronic device 801 can apply a relatively small power backoff compared to a case in which the multiple transmission beams are oriented in the same direction. The electronic device 801 can provide improved communication quality by reducing the amount of backoff.

[0218] Reference Figure 19, the electronic device 801 can communicate with the first base station 899. For example, the electronic device 801 can identify a first beam 1991 corresponding to a line of sight (LoS) and a second beam 1992 adjacent to the first beam 1991 as the multiple transmission beams. The first beam 1991 and the second beam 1992 can be assumed to be beams corresponding to the same direction. In this case, the electronic device 801 can identify whether there is a beam satisfying a specified condition and corresponding to a direction different from the direction of the first beam 1991 and the second beam 1992. For example, a third beam 1993 does not correspond to the direction of the first beam 1991 and the second beam 1992, but receives a signal reflected from the reflector 1910. For example, a reference signal received power associated with the third beam 1993 is at least a specified value. In this case, the electronic device 801 can communicate with the first base station 899 using the third beam 1993 instead of the first beam 1991 or the second beam 1992. For example, the electronic device 801 communicates using the first beam 1991 and the third beam 1993 or the second beam 1992 and the third beam 1993. The electronic device 801 can change a beam having a low communication quality among the first beam 1991 and the second beam 1992 to the third beam 1993. The electronic device 801 can use the third beam 1993 to reduce the amount of power backoff.

[0219] Figure 20 is a flowchart illustrating a method of determining whether multiple transmission beams of an electronic device correspond to the same direction according to an embodiment of the disclosure.

[0220] The transmission beam management method of the electronic device described above with reference to Figure 19 may be combined with the transmission beam power control method described above with reference to Figures 11 to 18 . For example, Figure 20 The method of the electronic device described above with reference to Figure 11 may correspond to Figure 16 operation 1610 of the method 1600, Figure 17 operation 1710 of the method 1700, or Figure 18 operation 1815 of the method 1800.

[0221] Referring to Figure 20 , in the method 2000, in operation 2005, the processor 820 can determine whether the multiple identified transmission beams correspond to the same direction. For example, as described above with reference to operation 1110 of the method 1100, the processor 820 can determine whether the multiple beams correspond to the same direction based on various methods. The definition of the multiple beams corresponding to the same direction is the same as described above with reference to Figure 11 . For example, as described above with reference to operation 1110 of the method 1100, the processor 820 can determine whether the multiple beams correspond to the same direction based on various methods. The definition of the multiple beams corresponding to the same direction is the same as described above with reference to Figure 12 . For example, as described above with reference to operation 1110 of the method 1100, the processor 820 can determine whether the multiple beams correspond to the same direction based on various methods. The definition of the multiple beams corresponding to the same direction is the same as described above with reference to

[0222] When the plurality of identified transmission beams do not correspond to the same direction (e.g., operation 2005 - No), the processor 820 can determine that the plurality of transmission beams do not correspond to the same direction in operation 2020.

[0223] When the plurality of identified transmission beams correspond to the same direction (e.g., operation 2005 - Yes), the processor 820 determines whether there is a beam satisfying a designated condition in operation 2010. For example, a beam having a reception strength of at least a designated value and corresponding to a direction different from the direction of the plurality of transmission beams can satisfy the designated condition.

[0224] When there is no beam satisfying the designated condition (e.g., operation 2010 - No), the processor 820 can determine that the plurality of beams correspond to the same direction in operation 2025.

[0225] When there is a beam satisfying the designated condition (e.g., operation 2010 - Yes), the processor 820 can change at least one of the plurality of transmission beams to the beam satisfying the designated condition in operation 2015. According to the change of the transmission beam, the processor 820 can determine that the plurality of transmission beams do not correspond to the same direction (e.g., operation 2020).

[0226] The structure of the electronic device of the disclosure and operations performed by the electronic device have been described with reference to Figures 1 to 20 The above-described structure and / or operations of the electronic device are illustrative, and obvious modifications can also be included in embodiments of the disclosure.

[0227] For example, the electronic device can include a means for identifying a transmission beam. The means for identifying a transmission beam can obtain information of beams that can be used by the electronic device in a transmission. The means for identifying a transmission beam can also identify or determine whether a plurality of identified beams correspond to the same direction. For example, the electronic device 801 in any combination of configurations capable of performing operations 1605 and 1610 of Figure 16 is included in the means for identifying a transmission beam.

[0228] For example, the electronic device includes a means for controlling transmission power. The means for controlling transmission power can be configured to control transmission power based on a combination of beams identified by the means for identifying a transmission beam (e.g., a combination of beams corresponding to the same direction or a combination of beams corresponding to different directions). For example, any combination of configurations of the electronic device 801 capable of performing operations 1615 and 1620 of Figure 16 is included in the means for controlling transmission power.

[0229] For example, the electronic device includes a component for transmitting a wireless signal. The component for transmitting a wireless signal can transmit a wireless signal with a transmission power controlled by a component for controlling a transmission power. For example, any component of the electronic device 801 for transmitting a wireless signal can be in the component for transmitting a wireless signal.

[0230] According to another embodiment, the electronic device can include a component for detecting an external object. The component for detecting an external object can identify a relative position (e.g., a direction and / or a distance) of the external object with respect to the electronic device and / or a type of the external object. For example, the component for detecting an external object identifies whether the external object is an object (e.g., an organic matter) corresponding to a type of a person. For example, the electronic device detects the external object using a proximity sensor, a grip sensor, and / or a grip for transmitting / receiving radio waves. For example, the electronic device identifies a position and a type of the external object by transmitting a signal and receiving a reflected wave using an antenna module (e.g., the antenna modules 891, 892, and 893 of the electronic device 801). Figure 8 The electronic device can identify the position and the type of the external object by comparing a phase and an amplitude between a transmitted signal and a received signal.

[0231] In the various embodiments described above, the electronic device (e.g., the electronic device 801) can apply the above-described transmission power control method based on an external object. For example, when a plurality of transmission beams correspond to a same direction (e.g., operation 1610-Yes), the electronic device 801 determines whether an external object corresponding to a person exists in the same direction. When there is no person in the direction corresponding to the plurality of beams, the electronic device 801 can perform a first type of transmission power control (e.g., operation 1620 of FIG. 16). Figure 8 When there is a person in the direction corresponding to the plurality of beams, the electronic device 801 can perform a second type of transmission power control or a third type of transmission power control (e.g., operation 1615 of FIG. 16). Figure 16 Figure 16 According to another embodiment, a mobile electronic device (e.g., the electronic device 801) can include at least one antenna module (e.g., the antenna modules 891, 892, and 893 of the electronic device 801).

Figure 8 ​The antenna module includes at least one array antenna, a processor (e.g., the processor 820) operatively connected to the at least one antenna module, and a memory (e.g., the memory 830) operatively connected to the processor. The memory can include instructions that, when executed, cause the processor to identify a plurality of beams including a first beam and a second beam for communicating with at least one base station using the at least one antenna module, identify a third beam corresponding to a direction different from the first direction and whose received signal strength from the at least one base station is at least a specified value when the first beam and the second beam correspond to the same first direction, communicate with the at least one base station by applying power backoff of beams corresponding to the same direction to the first beam and the second beam when identification of the third beam fails, and change the second beam to the third beam and communicate with the at least one base station using the first beam and the third beam without applying the power backoff of beams corresponding to the same direction when the third beam is identified.

[0233] The instructions, when executed, can cause the processor to control transmission power associated with each of the plurality of beams based on a maximum transmission power that is the same as a maximum transmission power of a single-beam transmission when the plurality of beams correspond to different directions. The instructions, when executed, can cause the processor to identify whether the first beam and the second beam correspond to the same direction based on beam index information about the plurality of beams. The at least one antenna module can include first and second antenna modules arranged to face different directions. The first beam and the second beam can correspond to the same direction when the first beam and the second beam are associated with a same one of the first and second antenna modules. The first beam can correspond to a vertically polarized wave and the second beam can correspond to a horizontally polarized wave. The instructions, when executed, can cause the processor to apply a first power backoff to the first beam and a second power backoff greater than the first power backoff to the second beam when identification of the third beam fails. The first beam can be associated with a higher frequency band than the second beam, or the first and second beams can be associated with different types of cells. The instructions, when executed, can cause the processor to perform spatial multiplexing or spatial diversity by transmitting a wireless signal using the plurality of beams.

[0234] According to an embodiment, a method for multi-beam transmission of a mobile communication device can include identifying a plurality of beams including a first beam and a second beam to be used for transmission, determining whether the first beam and the second beam correspond to a same first direction, when the first beam and the second beam correspond to the same first direction, determining whether a third beam corresponding to a direction different from the first direction and having a received signal strength of at least a specified value exists, when the third beam does not exist, transmitting a signal by applying power backoff of beams corresponding to the same direction to the first beam and the second beam, and when the third beam exists, changing the second beam to the third beam and transmitting a signal without applying power backoff of beams corresponding to the same direction.

The determining whether the plurality of identified beams correspond to the same direction can include identifying whether the first beam and the second beam correspond to the same direction based on beam index information about the first beam and the second beam. The determining whether the first beam and the second beam correspond to the same direction can include identifying that the first beam and the second beam correspond to the same direction when the first beam and the second beam are associated with a same antenna module of a plurality of antenna modules of the electronic device. The transmitting a signal by applying power backoff of beams corresponding to the same direction to the first beam and the second beam can include applying a first power backoff to the first beam and a second power backoff greater than the first power backoff to the second beam. The first beam can be associated with a higher frequency band than the second beam, or the first beam and the second beam can be associated with different types of cells.

The memory can store instructions that, when executed, cause the processor to form a first beam and a second beam using at least one of the first antenna module or the second antenna module, and control transmission power associated with the first beam and the second beam based on a relatively lower maximum transmission power compared to single-beam transmission when the first beam and the second beam correspond to a same direction. The instructions, when executed, can cause the processor to control the transmission power associated with each of the first beam and the second beam based on a maximum transmission power that is the same as a maximum transmission power of single-beam transmission when the first beam and the second beam correspond to different directions. The instructions, when executed, can cause the processor to apply a first power backoff to a first transmission power control associated with the first beam, and apply a second power backoff that is greater than the first power backoff to a second transmission power control associated with the second beam.
