Description

Electronic device supporting heat relief and control method of the electronic device

The present invention relates to an electronic device supporting 5G communication, and more particularly, to an electronic device capable of effectively performing 5G communication while effectively alleviating heat generated by the electronic device, and a method for controlling the electronic device .

Recently, various electronic devices including electronic devices have been commercialized as wireless communication systems using LTE communication technology to provide various services. In addition, it is expected that a wireless communication system using 5G communication technology will be commercialized in the future to provide various services. Meanwhile, some of the LTE frequency bands may be allocated to provide 5G communication services.

As such, high-speed wireless data communication is supported, and the electronic device includes a plurality of antenna modules, and high-speed wireless data communication can be performed by applying a higher voltage to the plurality of antenna modules. In particular, in the case of a 5G communication method using a millimeter wave (mmWave) using a very high frequency ranging from 30 to 300 GHz or a 5G communication method using a frequency (Sub 6) of a band below 6 GHz, the advantage of using a high bandwidth is to have a very high data transmission speed However, since the voltage applied to the PA (Power Amplifier, hereinafter referred to as the Power Amplifier) is high, there is a problem that a sudden temperature rise may be caused around the PA.

Accordingly, research to alleviate a sudden temperature rise that may occur during communication according to the 5G communication method (hereinafter referred to as 5G communication) is being actively conducted.

As a part of this study, a thermal mitigation method was devised to relieve the heat of the antenna module through a specific heat alleviation operation corresponding to each temperature step by step according to the temperature of the antenna module. In the case of this heat mitigation method, instead of limiting the 5G communication performance by limiting the data transmission rate or reducing the number of antennas as the temperature of the antenna module increases, the transmission rate of downloaded or uploaded data is gradually limited, instead of limiting the antenna module’s performance. A way to relieve heat.

In the case of such a heat alleviation method, a specific heat relief operation corresponding to each temperature step by step is pre-designated. For example, when the antenna module reaches a first temperature in a normal operating state, a heat relief operation according to the first temperature may be performed, and when the second temperature is reached, a heat relief operation according to the second temperature may be performed. In this case, the second temperature may be higher than the first temperature.

Meanwhile, in the case of electronic devices, the time it takes for 5G communication to reach the limiting temperature may vary depending on the operating state. For example, when the transmission speed of data uploaded or downloaded from the electronic device is low, it may take a longer time until the temperature at which 5G communication is restricted is reached, compared to when the data transmission speed is high.

However, in the case of a typical heat alleviation method, when the temperature of the antenna module reaches a specific temperature range, the heat relief operation corresponding to the specific temperature range is uniformly performed. Therefore, there is a problem that the 5G communication is unnecessarily limited according to the heat alleviation operation because the mitigation operation is performed even though the time required for the 5G communication to reach the limiting temperature is sufficient.

An object of the present invention is to solve the above and other problems, and to provide an electronic device capable of maintaining a normal 5G communication state for a longer period of time during 5G communication and a control method of the electronic device.

In an embodiment, the modem detects the quality of data transmitted/received from the electronic device instead of the data transmission rate according to the preset period, and determines a heat relief start temperature at which heat relief starts according to the detected data quality. It is characterized in that, when the time in which the detected data quality is maintained at a preset level good for a certain period of time or more, the heating alleviation start temperature is increased.

In an embodiment, the data quality is detected based on at least one of a signal to noise ratio (SNR) and a bit error rate (BER) of data transmitted or received by the electronic device.

In an embodiment, the modem further detects a service provided by the electronic device, and changes a heat relief start temperature at which the heat relief starts based on whether there is a predetermined service among the detected services. do it with

In one embodiment, when the temperature of the at least one antenna module falls within a preset temperature range, the modem limits the data transmission rate according to the detected temperature to relieve heat of the at least one antenna module characterized in that

In an embodiment, when the modem limits the data transmission rate to relieve heat of the at least one antenna module, based on the detected data transmission rate, a data transmission rate limit value according to the detected temperature It is characterized in that it is set differently.

In an embodiment, the modem is characterized in that the lower the detected data transfer rate, the smaller the data transfer rate limit value corresponding to the detected temperature is set.

In an embodiment, the modem detects the data transfer rate according to a preset period, determines the data transfer rate limit value differently according to the detected transfer rate, and determines the data transfer rate according to the data transfer rate detection result of the previous period. In a state in which the data transfer rate limit value is changed, when the detected data transfer rate again exceeds a preset threshold rate, the changed data transfer rate limit value is restored.

In one embodiment, the modem, when alleviating heat of the at least one antenna module by limiting the data transmission rate, detects the quality of data transmitted and received by the electronic device according to a preset period, It is characterized in that the data transmission rate limit value is set differently according to the detected temperature based on the data quality.

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

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

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

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

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

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

3B illustrates a configuration of a wireless communication unit of an electronic device operable in a plurality of wireless communication systems according to an embodiment. Referring to FIG. 3B , the electronic device includes a first power amplifier 210 , a second power amplifier 220 , and an RFIC 250 . In addition, the electronic device may further include a modem (Modem, 270) and an application processor (AP: Application Processor, 280). Here, the modem 270 and the application processor AP 280 are physically implemented on a single chip, and may be implemented in a logically and functionally separated form. However, the present invention is not limited thereto and may be implemented in the form of physically separated chips depending on the application.

On the other hand, the electronic device includes a plurality of low noise amplifiers (LNA: Low Noise Amplifiers, 261 to 264) in the receiver. Here, the first power amplifier 210 , the second power amplifier 220 , the RFIC 250 , and the plurality of low-noise amplifiers 261 to 264 are all operable in the first communication system and the second communication system. In this case, the first communication system and the second communication system may be a 4G communication system and a 5G communication system, respectively.

As shown in FIG. 2B , the RFIC 250 may be configured as a 4G/5G integrated type, but is not limited thereto and may be configured as a 4G/5G separate type according to an application. When the RFIC 250 is configured as a 4G/5G integrated type, it is advantageous in terms of synchronization between 4G/5G circuits, as well as the advantage that control signaling by the modem 270 can be simplified.

Meanwhile, when the RFIC 250 is configured as a 4G/5G separate type, it may be referred to as a 4G RFIC and a 5G RFIC, respectively. In particular, when the difference between the 5G band and the 4G band is large, such as when the 5G band is configured as a millimeter wave band, the RFIC 250 may be configured as a 4G/5G separate type. As such, when the RFIC 250 is configured as a 4G/5G separate type, there is an advantage that RF characteristics can be optimized for each of the 4G band and the 5G band.

Meanwhile, even when the RFIC 250 is configured as a 4G/5G separate type, the 4G RFIC and the 5G RFIC are logically and functionally separated, and it is also possible to be physically implemented on a single chip.

On the other hand, the application processor (AP, 280) is configured to control the operation of each component of the electronic device. Specifically, the application processor (AP) 280 may control the operation of each component of the electronic device through the modem 270 .

For example, the modem 270 may be controlled through a power management IC (PMIC) for low power operation of the electronic device. Accordingly, the modem 270 may operate the power circuits of the transmitter and the receiver in the low power mode through the RFIC 250 .

In this regard, when it is determined that the electronic device is in an idle mode, the application processor (AP) 280 may control the RFIC 250 through the modem 270 as follows. For example, if the electronic device is in an idle mode, the RFIC via the modem 270 so that at least one of the first and

second power amplifiers

210 and 220 is operated in the low power mode or turned off 250 can be controlled.

According to another embodiment, when the electronic device is in a low battery mode, the application processor (AP) 280 may control the modem 270 to provide wireless communication capable of low power communication. For example, when the electronic device is connected to a plurality of entities among a 4G base station, a 5G base station, and an access point, the application processor (AP) 280 may control the modem 270 to enable wireless communication with the lowest power. Accordingly, the application processor (AP) 280 may control the modem 270 and the RFIC 250 to perform short-range communication using only the short-range communication module 113 even at sacrificing some throughput.

According to another embodiment, when the remaining battery level of the electronic device is equal to or greater than a threshold, the modem 270 may be controlled to select an optimal wireless interface. For example, the application processor (AP) 280 may control the modem 270 to receive through both the 4G base station and the 5G base station according to the remaining battery level and available radio resource information. In this case, the application processor (AP) 280 may receive the remaining battery level information from the PMIC and the available radio resource information from the modem 270 . Accordingly, if the battery level and available radio resources are sufficient, the application processor (AP) 280 may control the modem 270 and the RFIC 250 to receive through both the 4G base station and the 5G base station.

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

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

In addition, when each communication system is separated, it is impossible to control other communication systems as necessary, or efficient resource allocation is impossible because the system delay is increased. On the other hand, the multi-transmission/reception system as shown in FIG. 3B has an advantage in that it is possible to control other communication systems as necessary, and thus system delay can be minimized, so that efficient resource allocation is possible.

Meanwhile, the first power amplifier 210 and the second power amplifier 220 may operate in at least one of the first and second communication systems. In this regard, when the 5G communication system operates in the 4G band or the Sub6 band, the first and

second power amplifiers

210 and 220 may operate in both the first and second communication systems.

On the other hand, when the 5G communication system operates in the millimeter wave (mmWave) band, one of the first and

second power amplifiers

210 and 220 operates in the 4G band, and the other operates in the millimeter wave band. have.

Meanwhile, by integrating the transceiver and the receiving unit, two different wireless communication systems can be implemented with one antenna by using an antenna for both transmitting and receiving. In this case, 4x4 MIMO can be implemented using four antennas as shown in FIG. 3B. In this case, 4x4 DL MIMO may be performed through the downlink (DL).

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

Meanwhile, 2x2 MIMO implementation is possible using two antennas connected to the first power amplifier 210 and the second power amplifier 220 among the four antennas. In this case, 2x2 UL MIMO (2 Tx) may be performed through the uplink (UL). Alternatively, it is not limited to 2x2 UL MIMO, and may be implemented with 1 Tx or 4 Tx. In this case, when the 5G communication system is implemented as 1 Tx, only one of the first and

second power amplifiers

210 and 220 may operate in the 5G band. On the other hand, when the 5G communication system is implemented as 4Tx, an additional power amplifier operating in the 5G band may be further provided. Alternatively, a transmission signal may be branched in each of one or two transmission paths, and the branched transmission signal may be connected to a plurality of antennas.

On the other hand, since a switch-type splitter or a power divider is built inside the RFIC corresponding to the RFIC 250, there is no need for a separate component to be disposed outside, thereby improving component mountability. can Specifically, it is possible to select the transmitter (TX) of two different communication systems by using a single pole double throw (SPDT) type switch inside the RFIC corresponding to the RFIC 250 .

In addition, the electronic device operable in a plurality of wireless communication systems according to an embodiment may further include a duplexer 231 , a filter 232 , and a switch 233 .

The duplexer 231 is configured to mutually separate signals of a transmission band and a reception band. At this time, the signals of the transmission band transmitted through the first and

second power amplifiers

210 and 220 are applied to the antennas ANT1 and ANT4 through the first output port of the duplexer 231 . On the other hand, signals of the reception band received through the antennas ANT1 and ANT4 are received by the

low noise amplifiers

261 and 264 through the second output port of the duplexer 231 .

The filter 232 may be configured to pass a signal of a transmission band or a reception band and block a signal of the remaining band. In this case, the filter 232 may include a transmit filter connected to a first output port of the duplexer 231 and a receive filter connected to a second output port of the duplexer 231 . Alternatively, the filter 232 may be configured to pass only a signal of a transmission band or only a signal of a reception band according to the control signal.

The switch 233 is configured to transmit either only a transmit signal or a receive signal. In an embodiment of the present invention, the switch 233 may be configured in a single pole double throw (SPDT) type to separate a transmission signal and a reception signal in a time division multiplexing (TDD) method. In this case, the transmission signal and the reception signal are signals of the same frequency band, and accordingly, the duplexer 231 may be implemented in the form of a circulator.

On the other hand, in another embodiment of the present invention, the switch 233 is also applicable to a frequency division multiplexing (FDD: Time Division Duplex) scheme. In this case, the switch 233 may be configured in a double pole double throw (DPDT) type to connect or block a transmission signal and a reception signal, respectively. Meanwhile, since the transmission signal and the reception signal can be separated by the duplexer 231 , the switch 233 is not necessarily required.

Referring to FIG. 6A , a Next Generation Radio Access Network (NG-RAN) 600 is a Random Access (NG-RA) user plane (new sublayer/PDCP/RLC/MAC/PHY) and a control plane for User Equipment (UE). (RRC) consists of gNBs 310 that provide protocol termination.

The gNBs 610 are interconnected via an Xn interface 612 . The gNB 610 is also connected to a Next Generation Core (NGC) 620 through an NG interface. More specifically, the gNB 610 is connected to an Access and Mobility Management Function (AMF) 631 through an N2 interface and a User Plane Function (UPF) 632 through an N3 interface.

Meanwhile, functions related to data transfer or data flow control may be performed in the user plane.

Meanwhile, referring to the above, a wireless communication system including an electronic device and a base station (gNB) illustrated in FIG. 6A will be described as follows. In this regard, FIG. 6B illustrates a block diagram of a wireless communication system to which the methods proposed in the present specification can be applied.

Referring to FIG. 6B , the wireless communication system includes a first communication device 650 and/or a second communication device 660 . 'A and/or B' may be interpreted as having the same meaning as 'including at least one of A or B'. The first communication device may represent the base station and the second communication device may represent the terminal (or the first communication device may represent the terminal and the second communication device may represent the base station).

Base station (BS) is a fixed station (fixed station), Node B, evolved-NodeB (eNB), gNB (Next Generation NodeB), BTS (base transceiver system), access point (AP: Access Point), gNB (general) NB), 5G system, network, AI system, RSU (road side unit), may be replaced by terms such as robot.

The first communication device 650 and the second communication device 660 are a processor (processor, 651, 661), memory (memory, 654, 664), one or more Tx / Rx RF module (radio frequency module, 655, 665) , including

Tx processors

652 and 662 ,

Rx processors

653 and 663 , and

antennas

656 and 666 . The processors 651 and 661 implement the above salpin functions, processes and/or methods and the functions, processes and/or methods to be described later. More specifically, in the DL (communication from the first communication device 650 to the second communication device 660 ), a higher layer packet from the core network (NGC) is provided to the processor 651 . The processor 651 implements the function of the L2 layer. In the DL, the processor 651 provides multiplexing between logical channels and transport channels, radio resource allocation, to the second communication device 660 , and is responsible for signaling to the second communication device 660 .

A transmit (TX) processor 652 implements various signal processing functions for the L1 layer (ie, the physical layer). The signal processing function facilitates forward error correction (FEC) in the second communication device 660 and includes coding and interleaving. The coded and modulated symbols are divided into parallel streams, each stream mapped to OFDM subcarriers, multiplexed with a reference signal (RS) in the time and/or frequency domain, and using Inverse Fast Fourier Transform (IFFT) are combined together to create a physical channel carrying a stream of time domain OFDMA symbols.

The OFDM stream is spatially precoded to generate multiple spatial streams. Each spatial stream may be provided to a different antenna 656 via a separate Tx/Rx module (or transceiver, 655 ). Each Tx/Rx module may modulate an RF carrier with a respective spatial stream for transmission.

In the second communication device 660 , each Tx/Rx module (or transceiver, 665 ) receives a signal via a respective antenna 666 of each Tx/Rx module 665 . Each Tx/Rx module 665 recovers information modulated with an RF carrier and provides it to a receive (RX) processor 663 . The RX processor 663 implements various signal processing functions of layer 1. The RX processor 663 may perform spatial processing on the information to recover any spatial streams destined for the second communication device 660 . If multiple spatial streams are directed to the second communication device 660 , they may be combined into a single OFDMA symbol stream by multiple RX processors 663 . The RX processor 663 transforms the OFDMA symbol stream from the time domain to the frequency domain using a Fast Fourier Transform (FFT).

The frequency domain signal includes a separate OFDMA symbol stream for each subcarrier of the OFDM signal. The symbols and reference signal on each subcarrier are recovered and demodulated by determining the most probable signal placement points transmitted by the first communication device. These soft decisions may be based on channel estimate values. The soft decisions are decoded and deinterleaved to recover the data and control signal originally transmitted by the first communication device 650 on the physical channel. Corresponding data and control signals are provided to processor 661 .

The UL (second communication device 660 to first communication device 650 communication) is handled in the first communication device 650 in a manner similar to that described with respect to the receiver function in the second communication device 660 . . Each Tx/Rx module 665 receives a signal via a respective antenna 666 . Each Tx/Rx module 665 provides an RF carrier and information to the RX processor 663 . The processor 661 may be associated with a memory 664 that stores program code and data. Memory 664 may be referred to as a computer-readable medium.

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

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

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

Numerology corresponds to one subcarrier spacing in the frequency domain. By scaling the reference subcarrier spacing by an integer N, different numerology can be defined. In this regard, Fig. 4A shows an example of a frame structure in NR. Meanwhile, FIG. 4B shows a change in slot length according to a change in subcarrier spacing in NR.

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

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

		Cyclic prefix(CP)Cyclic prefix (CP)
00	1515	NormalNormal
1One	3030	Normal Normal
22	6060	Normal, ExtendedNormal, Extended
33	120120	Normal Normal
44	240240	NormalNormal

NR supports multiple numerology (or subcarrier spacing (SCS)) to support various 5G services. For example, when SCS is 15kHz, it supports a wide area in traditional cellular bands, and when SCS is 30kHz/60kHz, dense-urban, lower latency and a wider carrier bandwidth, and when the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz to overcome phase noise.

The NR frequency band is defined as a frequency range of two types (FR1, FR2). FR1 is the sub 6GHz range, and FR2 is the above 6GHz range, which may mean a millimeter wave (mmW).

Table 2 below shows the definition of the NR frequency band.

Frequency RangedesignationFrequency Rangedesignation	Corresponding frequencyrangeCorresponding frequencyrange	Subcarrier Spacing Subcarrier Spacing

FR1FR1	450 MHz - 6000 MHz450 MHz - 6000 MHz	15, 30, 60 KHz15, 30, 60 KHz
FR2FR2	24250 MHz - 52600 MHz24250 MHz - 52600 MHz	60, 120, 240 KHz60, 120, 240 KHz

With respect to the frame structure in the NR system, the sizes of various fields in the time domain are expressed as multiples of a specific time unit. 7A is an example of SCS of 60 kHz, and one subframe may include four slots. One subframe = {1,2,4} slots shown in FIG. 7A is an example, and the number of slot(s) that may be included in one subframe may be one, two, or four.

Also, a mini-slot may contain 2, 4 or 7 symbols, or may contain more or fewer symbols.

Referring to FIG. 7B , the subcarrier interval of 5G NR phase I and the OFDM symbol length accordingly are shown. Each subcarrier interval is extended by a power of 2, and the symbol length is reduced in inverse proportion to this. In FR1, subcarrier spacings of 15 kHz, 30 kHz and 60 kHz are available depending on the frequency band/bandwidth. In FR2, 60 kHz and 120 kHz can be used for the data channel, and 240 kHz can be used for the synchronization signal.

In 5G NR, a basic unit of scheduling is defined as a slot, and the number of OFDM symbols included in one slot may be limited to 14 as shown in FIG. 7A or 7B regardless of subcarrier spacing. Referring to FIG. 7B , when a wide subcarrier interval is used, the length of one slot is shortened in inverse proportion to reduce transmission delay in a radio section. In addition, in order to efficiently support ultra reliable low latency communication (uRLLC), scheduling in units of minislots (eg, 2, 4, 7 symbols) may be supported as described above in addition to scheduling in units of slots.

Considering the above-described technical features, the slots in 5G NR described herein may be provided at the same interval as the slots of 4G LTE or may be provided as slots of various sizes. As an example, the slot interval in 5G NR may be configured as 0.5 ms, which is the same as the slot interval of 4G LTE. As another example, the slot interval in 5G NR may be configured as 0.25 ms, which is a narrower interval than the slot interval of 4G LTE.

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

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

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

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

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

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

Meanwhile, the resource structure of the time domain and the frequency domain may define an NR resource grid as shown in FIG. 8A . According to a subcarrier spacing (SubCarrier Spacing: SCS), the resource grid may be changed as the number of available subcarriers and OFDM symbols varies. That is, with respect to each numerology and carrier, NR is a value obtained by multiplying the maximum number of resource blocks per subcarrier interval by the number of subcarriers per resource block, and a value determined by the number of OFDM symbols per subframe as the length. A resource grid can be defined.

In addition, to support agile and efficient use of TDD resources, NR may implement a flexible slot structure. As an example, as shown in (a) and (b) of FIG. 8B , all slots may be allocated as DL (DownLink) and all UL (UploadLink) slots. Alternatively, a mixture of DL and UL may be used to allocate service asymmetric traffic. DL control takes place at the beginning of the slot, UL control can happen at the end, statically configure the mixed DL/UL slot as in LTE DL/UL TDD configuration or dynamically change the allocation of DL/UL mix can Thus, efficiency and scheduling can be improved depending on traffic requirements.

Meanwhile, the electronic device 100 described herein may maintain a connection state with a 4G base station (eNB) and a 5G base station (eNB) through the 4G wireless communication module 111 and/or the 5G wireless communication module 112 . . In this regard, as described above, FIG. 9 shows a configuration in which the electronic device 100 is interfaced with a plurality of base stations or network entities according to an embodiment.

Referring to FIG. 9 , 4G/5G deployment options are shown. In relation to 4G/5G deployment, when multi-RAT of 4G LTE and 5G NR is supported and in non-standalone (NSA) mode, it can be implemented as EN-DC of option 3 or NGEN-DC of option 5. On the other hand, if multi-RAT is supported and in standalone (SA) mode, it may be implemented as NE-DC of option 4. In addition, when single RAT is supported and in standalone (SA) mode, it may be implemented as NR-DC of option 2.

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

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

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

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

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

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

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

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

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

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

Meanwhile, according to the NSA structure according to the MRDC (Multi RAT (Radio Access Technology) Dual Connectivity), the electronic device may be connected to a network according to a plurality of different communication methods at the same time, and may receive data from the connected networks. FIG. 10 shows an E-UTRA New Radio Dual Connectivity (EN-DC) structure as such an NSA structure in more detail.

Referring to FIG. 10 , the electronic device 100 may be simultaneously connected to the eNB 1000 serving as a master node and the en-gNB 1010 serving as a secondary node.

Here, the eNB 1000 may create an S1-MME control connection with the MME, which is a control entity of the EPC, which is the core of the LTE system. In addition, transmission and reception of NAS control messages can be relayed between the MME and the electronic device through the S1-MME control connection. In addition, an RRC connection can be created with an electronic device using LTE Radio technology, and an RRC state can be managed based on the connection.

Meanwhile, the en-gNB 1010 may be involved only in an additional data connection for transmitting/receiving data of a predetermined size or more, without being involved in the control connection and NAS message relay related to the EPC.

Meanwhile, for a DC (Dual Connectivity) connection, the electronic device 100 may first attach to the EPC through the eNB 1000 . In addition, a Packet Data Network (PDN) connection and bearers may be created. And when the PDN connection and the bearer are created, the electronic device may be in an RRC-connected state with the eNB 1000 .

Then, the master node, the eNB 1000 , the current congestion state of the eNB 1000 , the data transmission/reception status of the electronic device 100 , and the en-gNB that will serve as a secondary node around the eNB 1000 . DC use of the electronic device may be determined in consideration of the existence of the 1010 and the congestion state of the en-gNB 1010 .

And when DC use is determined, the eNB 1000 may transmit/receive an X2-C control message to and from the en-gNB 1010 through the X2 interface. In addition, through the exchange of control messages, a procedure of allowing some of the bearers that service data transmission/reception to the electronic device 100 to be serviced through the en-gNB 1010 with the LTE radio resource controlled by the eNB 1000 may be executed.

Therefore, some of the bearers that service data transmission and reception to the electronic device 100 as LTE radio resources are transferred to the en-gNB 1010, and the electronic device 100 is transferred to the en-gNB 1010 through some of the transferred bearers. Data can be transmitted/received using an NR radio resource controlled by . Accordingly, the electronic device may be connected to both the eNB 1000 and the en-gNB 1010 to transmit/receive data through both LTE, that is, 4G radio resource and NR, that is, 5G radio resource.

The wireless communication unit of the electronic device 100 according to an embodiment of the present invention may include two or more power amplifiers. However, for simplicity of description, it is assumed that multiplex transmission is performed when two power amplifiers are provided as shown in FIG. 11 . However, it is not limited to such a structure, and it is of course that more power amplifiers or a greater number of communication systems may be provided depending on the application.

Referring to FIG. 11 , the wireless communication unit of the electronic device 100 includes a first power amplifier 300 , a first low-noise amplifier 302 , a second power amplifier 310 , a second low-noise amplifier 312 , and a modem 270 . ), and a power supply unit 290 .

Here, the modem 270 may include a first communication module 360 capable of operating in a 5G communication system and a second communication module 350 operating in a 4G communication system. In addition, the second communication module 360 and the modem 270 may be physically separated or implemented in a physically separated structure on one chip. However, the present invention is not limited thereto, and the modem 270 may be formed integrally including the first communication module 360 and the second communication module 350 .

In addition, the first power amplifier 300 and the first low-noise amplifier 302 may operate in a first communication system, and the second power amplifier 310 and the second low-noise amplifier 312 may operate in a second communication system.

Meanwhile, the modem 270 and the first communication module 360 may be electrically connected. In addition, the first communication module 360 may perform modulation/demodulation for transmission or reception of a 5G signal under the control of the modem 270 . In this case, the modem 270 may control the operating state (eg, activated or deactivated) of the first communication module 360 .

For example, the modem 270 may be configured to receive data through both the 4G base station and the 5G base station according to the result of detecting the operation state of the electronic device 100 detected by the application processor (AP) 280. ) can be controlled. In this case, the modem 270 may activate the first communication module 360 , and the activated first communication module 360 uses a 5G base station (cell) that meets a preset condition from around the electronic device 100 . It is possible to provide a service through a 5G network by searching, adding the found 5G base station (5G Cell ADD), and performing wireless communication. In this case, the electronic device 100 may operate in a stand-alone (SA) method that can be connected only to a 5G network or a non-stand-alone (NSA) method that can be connected to both a 4G network and a 5G network.

On the other hand, the modem 270 may deactivate the first communication module 360 according to the detection result of the operation state of the electronic device 100 . In this case, the modem 270 may cause the first communication module 360 to operate in a low power mode.

Meanwhile, the first communication module 360 switched to the low power mode may not search for a 5G base station. Then, adding a 5G base station (5G Cell ADD) and wireless communication with the searched 5G base station may not be made, and the electronic device 100 performs wireless communication only with the 4G base station through the second communication module 350. It can operate in a state, i.e. connected to a 4G network only.

Meanwhile, the power supply unit 290 may supply power required to drive the modem 270 and the first communication module 360 . Here, the power supply 290 may control the current supplied to the first communication module 360 according to the control of the modem 270 . In this case, the modem 270 may deactivate the first communication module 360 by controlling the power supply unit 290 so that a current less than a preset threshold is supplied to the first communication module 360 .

For example, the first communication module 360 may operate in a normal operation mode when the current supplied from the power supply unit 290 is equal to or greater than a preset threshold value. Then, the first communication module 360 may search for a 5G base station (cell), add the found 5G base station (5G Cell ADD), and perform wireless communication.

On the other hand, when the current supplied from the power supply unit 290 is less than a preset threshold, the first communication module 360 may operate in a low power mode. Then, the first communication module 360 may stop searching for a 5G base station (cell). Accordingly, the electronic device 100 may operate in a manner that is connected only to the 4G network.

Meanwhile, the first communication module 360 may include a temperature sensor 370 . The temperature sensor 370 may detect the temperature of the first communication module 360 and transmit the detected temperature to the modem 270 . Accordingly, the modem 270 may sense the temperature of the first communication module 350 based on the temperature value detected by the temperature sensor 370 .

Meanwhile, in FIG. 11 , the configuration in which the temperature sensor 370 is provided in the first communication module 360 is disclosed, but the temperature sensor 370 includes a first power amplifier ( 300) or may be provided in at least one of the first low-noise amplifier 302 for amplifying a signal received according to the first communication method. In this case, the temperature of the first communication module 360 may be the temperature detected by the first power amplifier 300 or the first low noise amplifier 302 .

Meanwhile, in the following description, specific operations and functions of the electronic device 100 according to the present invention provided with the multiple transmission/reception system as shown in FIG. 11 will be described.

First, FIG. 12A is an exemplary diagram illustrating an example of a heat alleviation method performed in the electronic device 100 when the electronic device 100 is connected to a base station for data download (Downlink) according to an embodiment of the present invention.

In general, in the downlink, heat relief may be performed according to the following three methods sequentially according to the heat generation temperature in a normal operating state (Normal Service).

1) Downlink Data throttling

When the temperature of the electronic device 100 rises and reaches a specific temperature (THDL_Throttling) due to high-speed download data processing, the temperature of the electronic device 100 is lowered by limiting the transmission rate of received data. In this case, when data throttling starts, a throttling timer operates, and if the heat of the electronic device 100 is not relieved after a certain period of time, the transmission rate limiting rate of the downloaded data is gradually increased, and the temperature It is a method of limiting the data transfer rate more significantly as the value is higher. In this case, as the data transmission speed is limited, the effect of alleviating heat of the electronic device 100 may be greater. Meanwhile, since data throughput is reduced when data throttling is performed, it has a trade-off relationship with 5G communication performance.

2) Secondary Cell (Secondary Cell, SCell) Restriction (Drop SCell)

The method of limiting the secondary cell is a heat alleviation method that can be applied to both the 5G communication method using the Sub 6 frequency band and the 5G communication method using the millimeter wave, and the electronic device 100 performs carrier aggregation. In the case of performing high-speed download data using way to limit it. In this case, since the number of usable frequency bands is reduced, power consumed by the antenna module is reduced, so that heat of the electronic device 100 can be alleviated. Since this method also reduces data throughput, it has a trade-off relationship with 5G communication performance.

3) Communication method conversion to 4G method (Fallback to 4G)

When the temperature of the electronic device 100 rises to the temperature at which 5G communication is restricted (THDL_5GDisable), the 5G communication module is switched to an off or low power mode, and is switched to another communication method such as a 4G communication method. In this case, 5G communication may not be performed until the temperature of the electronic device 100 is sufficiently lowered.

Meanwhile, as shown in the temperature condition of FIG. 12A , the data throttling method may be performed when the preset first temperature (THDL_Throttling) is higher than or equal to the second temperature (THDL_DropSCell), and the secondary cell limiting method is a preset first temperature (THDL_DropSCell). This may be performed when the second temperature (THDL_DropSCell) is equal to or greater than the third temperature (THDL_5GDisable). In addition, when the third temperature THDL_5GDisable is reached, the electronic device 100 may switch the communication method to the 4G method.

When the electronic device 100 performs 5G communication using the frequency of the Sub 6 band, in the uplink, heat relief is sequentially performed according to the heat generation temperature in the normal operating state (Normal Service) according to the following three methods. can be performed.

1) Uplink Data throttling

When the temperature of the electronic device 100 rises and reaches a specific temperature (THUL_Throttling) due to the high-speed processing of the uploaded data, the temperature of the electronic device 100 is lowered by limiting the transmission speed of the uploaded data. In this case, when data throttling starts, a throttling timer operates, and if the heat of the electronic device 100 is not relieved even after a certain period of time has elapsed, the transmission rate limiting rate of uploaded data is gradually increased, and the temperature It is a method of limiting the data transfer rate more significantly as the value is higher. In this case, as the data transmission speed is limited, the effect of alleviating heat of the electronic device 100 may be greater. On the other hand, when data throttling is performed, as in the case of download, data throughput is reduced, so it has a trade-off relationship with 5G communication performance.

2) TX antenna module maximum output limit (TX Power back off)

In the case of data upload, a lot of heat is generated in the Power Amplifier (PA) in order to amplify the power of the transmit antenna module (TX antenna module). Therefore, when the temperature of the electronic device 100 increases by more than a certain level (THUL_PwrBackoff), it is a method of alleviating heat of the transmitting antenna module by limiting the maximum output (MAX power) of the transmitting antenna module in stages according to the temperature. In this case, since the output of the transmit antenna module is limited, coverage (Uplink Coverage) and data throughput are reduced.

3) Switch communication method to 4G method (NR Disable)

When the temperature of the electronic device 100 rises to the temperature at which 5G communication is restricted (THUL_5GDisable), the 5G communication module is switched to an off or low power mode, and another communication method such as a 4G communication method is switched. In this case, 5G communication may not be performed until the temperature of the electronic device 100 is sufficiently lowered.

Meanwhile, as shown in the temperature condition of FIG. 12B , the data throttling method may be performed when the preset first temperature (THUL_Throttling) is greater than or equal to the second temperature (THUL_PwrBackoff), and the maximum output of the transmit antenna module is limited. This method may be performed when the preset second temperature THUL_PwrBackoff is greater than or equal to the third temperature THUL_5GDisable. And when the third temperature (THUL_5GDisable) is reached, the electronic device 100 may switch the communication method to the 4G method.

When the electronic device 100 performs 5G communication using a frequency of the millimeter wave band, during the uplink, heat relief is sequentially performed according to the heat generation temperature in the normal operating state (Normal Service) according to the following four methods. can be performed.

1) Uplink Data throttling

2) Reduce Antenna Element

In the case of the electronic device 100 using the 5G communication method, the antenna module may include a plurality of antennas forming an array. And it is possible to form a beam directed to the base station through the plurality of antennas (beam forming).

When the temperature of the electronic device 100 rises and reaches a specific temperature (THUL_AntElement) despite the uplink data throttling has been performed, the electronic device 100 includes a plurality of antennas used to form the beam in the antenna module. Some of them may be sequentially turned off according to the temperature of the antenna module. In this case, the number of used antennas may be reduced until at least one antenna remains, and power supplied to the antenna module may be reduced while the number of used antennas is reduced. Accordingly, the heat of the electronic device 100 can be alleviated. However, a beam shape may be distorted according to a decrease in the number of antennas forming a beam, and thus an uplink data throughput may be reduced.

3) Antenna module switching (Array Antenna panel switching)

On the other hand, when the number of antennas is reduced and only one remains, that is, when heat is generated above a specific temperature (THUL_AntPanel) in a state in which the number of antennas cannot be reduced any more, the electronic device 100 turns off the currently used antenna module and It is a method of dissipating heat using an antenna module attached to the location. In this case, the antenna module attached to the other location is an antenna module designed to point in a different direction, and has narrower coverage (Uplink coverage) and lower uplink data throughput than an antenna module (currently off) pointing to a base station. has a disadvantage.

4) Switch communication method to 4G method (NR Disable)

On the other hand, as shown in the temperature condition of FIG. 12C , the data throttling method may be performed when the preset first temperature (THUL_Throttling) is higher than or equal to the second temperature (THUL_AntElement), and reduces the number of antennas used. The method may be performed when the preset second temperature (THUL_AntElement) is greater than or equal to the third temperature (THUL_AntPanel). In addition, when the temperature of the electronic device 100 rises to the fourth temperature THUL_5GDisable despite the antenna module switching being performed, the electronic device 100 may switch the communication method to the 4G method.

Meanwhile, as shown in FIGS. 12A to 12C , the electronic device 100 according to an embodiment of the present invention performs 5G communication using a frequency of the Sub 6 band or the millimeter wave band, the temperature of the electronic device 100, That is, a predetermined heat alleviation operation may be performed according to the temperature of the antenna module. In this case, the heat alleviation operation of each step may be performed when the temperature of the electronic device 100 falls within a predetermined temperature range, and may be performed in stages according to the temperature.

Meanwhile, FIGS. 13A and 13B are flowcharts illustrating different operation processes in which the electronic device 100 according to an embodiment of the present invention changes a temperature condition for a heat alleviation operation according to the operating state of the electronic device 100 . .

First, referring to FIG. 13A , the modem 270 of the electronic device 100 according to an embodiment of the present invention may detect a transmission rate of data uploaded or downloaded during uplink or downlink ( S1302 ). In addition, it may be determined whether the detected data transmission rate is less than or equal to a preset threshold rate (S1304). In addition, if the detected data transmission rate is less than or equal to the threshold rate (S1305), the temperature conditions of each preset step may be changed for heat relief (S1306). This is because in general, the higher the data transmission speed, the more rapidly the temperature of the electronic device 100 increases.

Accordingly, the modem 270 of the electronic device 100 according to an embodiment of the present invention performs 5G communication when the temperature increase of the electronic device 100 is sufficiently slow, that is, the data transmission rate is less than or equal to a preset threshold speed. When the heating rate of the electronic device 100 according to the above is sufficiently slow, the time during which normal 5G communication is maintained can be further extended by changing the preset temperature condition to alleviate the heating.

For example, when the electronic device 100 is in a downlink state, if the transmission rate of data to be downloaded is less than or equal to the threshold speed as a result of the detection in step S1304, the modem 270 sets the at least one heat relief temperature described with reference to FIG. 12A. You can change the conditions.

For example, the modem 270 may increase the temperature condition set for the data throttling, that is, the first temperature THUL_Throttling by a preset first temperature value. Accordingly, even when the existing first temperature is reached, data throttling may not be performed, and the data throttling may be performed after the temperature further increases by the first temperature value. That is, it is possible to delay the time when data throttling starts, and accordingly, the time during which the 5G communication is normally performed (Normal Service) can be maintained longer.

Meanwhile, when the first temperature THUL_Throttling increases, a temperature condition set for limiting the secondary cell, that is, the second temperature THDL_DropSCell may also increase. For example, the second temperature THDL_DropSCell may be increased by a preset second temperature value.

Meanwhile, even when the first temperature THUL_Throttling and the second temperature THDL_DropSCell increase, the temperature condition for which the communication method is switched, that is, the third temperature THUL_5GDisable may be fixed. This is because the temperature condition at which the communication method is switched means a temperature at which 5G communication is impossible due to the heat of the electronic device 100 , so the temperature condition at which the communication method is switched can be fixed. In this case, even when the second temperature value increases, the third temperature condition is fixed, and the second temperature THDL_DropSCell must be less than the third temperature THUL_5GDisable. The second temperature value that is the temperature increase value may have a value smaller than the first temperature value that is the temperature increase value of the first temperature THUL_Throttling.

In addition, if the electronic device 100 is in the uplink state, the electronic device 100 performs 5G communication through a frequency of the Sub 6 band, and as a result of the detection in step S1304, the transmission rate of uploaded data is less than or equal to the threshold speed. In this case, the modem 270 may change at least one heat relaxation temperature condition described with reference to FIG. 12B .

Meanwhile, when the first temperature THUL_Throttling increases, a temperature condition set to limit the maximum output of the transmit antenna module, that is, the second temperature THUL_PwrBackoff may also increase. For example, the second temperature THUL_PwrBackoff may be increased by a preset second temperature value.

Meanwhile, even when the first temperature THUL_Throttling and the second temperature THUL_PwrBackoff increase, the temperature condition for which the communication method is switched, that is, the third temperature THUL_5GDisable may be fixed. This is because the temperature condition at which the communication method is switched means a temperature at which 5G communication is impossible due to the heat of the electronic device 100 , so the temperature condition at which the communication method is switched can be fixed. In this case, even when the second temperature value increases, the third temperature condition is fixed, and the second temperature THUL_PwrBackoff must be less than the third temperature THUL_5GDisable. The second temperature value that is the temperature increase value may have a value smaller than the first temperature value that is the temperature increase value of the first temperature THUL_Throttling.

In addition, if the electronic device 100 is in the uplink state, the electronic device 100 performs 5G communication through a frequency of the millimeter wave band, and as a result of the detection in step S1304, the transmission rate of uploaded data is less than or equal to the threshold speed In this case, the modem 270 may change at least one heat relaxation temperature condition described with reference to FIG. 12C .

For example, the modem 270 may increase the temperature condition set for the data throttling, that is, the first temperature THUL_Throttling by a preset first temperature value. Accordingly, even when the existing first temperature is reached, data throttling may not be performed, and the data throttling may be performed after the temperature further increases by the first temperature value. That is, it is possible to delay the time when data throttling starts, and accordingly, it is possible to further extend the time during which a state in which 5G communication is normally performed (Normal Service) is maintained.

Meanwhile, when the first temperature THUL_Throttling increases, a temperature condition set to reduce heat generation by reducing the number of used antennas, that is, the second temperature THUL_AntElement may also increase. For example, the second temperature THUL_AntElement may be increased by a preset second temperature value. In addition, when the second temperature THUL_AntElement increases, a temperature condition set to relieve heat by switching the antenna module, that is, the third temperature THUL_AntPanel may also increase. For example, the third temperature THUL_AntPanel may increase by a preset third temperature value.

Meanwhile, even when the first temperature THUL_Throttling, the second temperature THUL_AntElement, and the third temperature THUL_AntPanel increase, the temperature condition for which the communication method is switched, that is, the fourth temperature THUL_5GDisable may be fixed. This is because the temperature condition at which the communication method is switched means a temperature at which 5G communication is impossible due to the heat of the electronic device 100 , so the temperature condition at which the communication method is switched can be fixed. In this case, even when the third temperature value increases, the fourth temperature condition is fixed, and since the third temperature THUL_AntPanel must be less than the fourth temperature THUL_5GDisable, the third temperature THUL_AntPanel The third temperature value that is the temperature increase value may have a value smaller than the second temperature value that is the temperature increase value of the second temperature THUL_AntElement. Similarly, since the second temperature THUL_AntElement must be less than the third temperature THUL_AntPanel, the second temperature value that is the temperature increase value of the second temperature THUL_PwrBackoff is the temperature increase value of the first temperature THUL_Throttling. It may have a value smaller than the first temperature value.

Meanwhile, as a result of the detection in step S1304, if the detected data transmission rate exceeds the threshold speed, the modem 270 may terminate the operation process of FIG. 13A (S1308). In this case, the temperature conditions of each exothermic relief step may not be changed.

Meanwhile, the operation process described with reference to FIG. 13A may be repeatedly performed according to a preset period. That is, when the process of FIG. 13A is performed, the modem 270 may detect whether a preset period expires, and when the preset period expires, start the process of FIG. 13A ( S1300 ).

When the data transfer rate is detected according to the preset period as described above, the detected data transfer rate may be an average of the data transfer rates detected during the preset period.

Here, the step S1304 may further include restoring the temperature conditions of each changed heat relief step (not shown). For example, in a state in which the start temperatures of each heat relief step are increased according to the determination result of step S1304 performed in the previous cycle, the data transmission rate detected as a result of determination of step S1304 of FIG. 13A performed again exceeds the threshold speed In this case, the modem 270 may restore the changed temperature conditions of each heat relief step. Then, according to the restored temperature condition and the current temperature of the electronic device 100, a heat relief operation according to a specific heat relief step may be performed.

Meanwhile, the step S1304 may further include checking a time when the detected data transfer rate is equal to or less than a threshold rate (not shown). In this case, the modem 270 may detect that the data transfer rate is less than or equal to the threshold speed only when the detected data transfer rate is equal to or less than the threshold rate and the data transfer rate equal to or less than the threshold rate is maintained for a preset time or longer. Accordingly, it is possible to prevent the temperature conditions set for heat alleviation from being changed when the data transmission rate temporarily decreases below the threshold speed.

Meanwhile, in FIG. 13A described above, the configuration of detecting the data transmission speed and changing the temperature conditions of each heat relief step according to the configuration has been described. However, it goes without saying that step S1306 may be performed according to the quality of transmitted or received data.

For example, when data quality (eg, signal to noise ratio (SNR)) is good, data transmission and reception may be performed even with a lower transmission output. Accordingly, the heat of the electronic device 100 can be alleviated. However, when the quality of data is not good, the transmission output needs to be further increased in order to transmit and receive data, so that the heat generation rate of the electronic device 100 may be faster.

Accordingly, when the quality of data transmitted and received by the electronic device 100 and the modem 270 according to an embodiment of the present invention is sufficiently good, by changing a preset temperature condition for heat relief in a manner similar to that described with reference to FIG. 13A . , it is possible to extend the time for which normal 5G communication is maintained.

In this case, step S1302 of FIG. 13A may be a step of measuring data quality. For example, the modem 270 may measure the quality of data transmitted and received in various methods such as SNR or bit error rate (BER) in step S1302. Also, as described above, if the process of FIG. 13A is performed every preset period, step S1302 may be a step of detecting an average of the data quality measured during the preset period.

Then, step S1304 of FIG. 13A may be a step of comparing the detected data quality with a preset threshold quality. In this case, if the data quality detected in step S1302 is better than the threshold quality, the modem 270 may proceed to step S1306 to change, ie, increase, the temperature conditions of each preset step for alleviating heat.

Meanwhile, FIG. 13A illustrates a configuration in which preset temperature conditions are changed for heat relief according to the result of detecting the data transmission speed, but otherwise, the temperature conditions may be changed based on the service provided by the electronic device 100. is of course 13B is a flowchart illustrating an operation process of the electronic device 100 according to an embodiment of the present invention in this case.

Referring to FIG. 13B , the modem 270 of the electronic device 100 according to an embodiment of the present invention may detect services currently being performed by the electronic device 100 ( S1352 ). For example, the modem 270 may detect a service currently being provided by detecting functions currently being executed in the electronic device 100 , that is, an application.

Then, the modem 270 may detect whether a preset service is included among the detected services (S1354). For example, the modem 270 may detect whether a service requiring a high data transmission rate is being provided among the detected services. Here, the service that requires the high data transfer rate is a service such as a video streaming service or an online game, which is designated in advance before the release of the electronic device 100 or selected by the user or from an external server that provides a service related to the present invention. It may be a designated service.

As a result of the detection in step S1354, if a service designated in advance as a service requiring a high data transmission rate is provided, the modem 270 does not change the temperature conditions of each step preset for alleviating the heat, as shown in FIG. 13B. The operation process may be terminated (S1358).

On the other hand, as a result of the detection in step S1354, if a service designated in advance as a service requiring a high data transmission rate is not provided, the modem 270 may change the temperature conditions of each preset step for alleviating the heat. That is, by increasing the temperature conditions of each of the heat alleviation steps, it is possible to further extend the time for which normal 5G communication is maintained.

Meanwhile, the process of FIG. 13B may also be repeatedly performed according to a preset period. In this case, when the preset period expires, the process of FIG. 13B may be started (S1300).

Meanwhile, the step S1354 may further include restoring the temperature conditions of each changed heat relief step (not shown). For example, according to the determination result of step S1354 performed in the previous cycle, in a state in which the start temperatures of each heat relief step are increased, as a result of the determination of step S1354 of FIG. 13A performed again, a service requiring a high data transmission rate If is being provided, the modem 270 may restore the changed temperature conditions of each heat relief step. Then, according to the restored temperature condition and the current temperature of the electronic device 100, a heat relief operation according to a specific heat relief step may be performed.

Meanwhile, the step S1354 may further include checking a time at which the service is provided when a service designated in advance as requiring a high data transmission rate is detected (not shown). In this case, the modem 270 may detect that the electronic device 100 is in a state of providing the predetermined service only when the predetermined service is provided for more than a predetermined time. Accordingly, it is possible to prevent a case in which temperature conditions set for heat relief do not change when the application providing the predetermined service is temporarily executed.

Meanwhile, in the above description, it has been described that the temperature condition may be changed according to the data transmission speed of the electronic device 100 , the quality of data transmitted or received, or the service provided by the electronic device 100 . However, depending on the data transmission speed, the quality of the transmitted or received data, or the service provided by the electronic device 100, the data transmission rate limited in the data throttling step, that is, the data transmission rate limiting rate may be different. Of course it could be.

For example, according to the above description, in the case of data throttling, which is one of the heat alleviation steps, when the temperature of the electronic device 100 is higher, the transmission rate limiting rate of uploaded data is gradually increased, so that the heat generation of the electronic device 100 is increased. This is a method of limiting the data transfer rate more severely.

For this data throttling, different data transfer rate limit values or data transfer rate limiting rates may be stored in the memory of the electronic device 100 according to the temperature of the electronic device 100, and the data transfer rate limit value or data transmission rate The speed limit rate may be set to have a larger value as the temperature increases.

In this case, the electronic device 100 according to an embodiment of the present invention limits the data transmission rate or the data transmission rate according to the data transmission rate, the quality of data transmitted or received, or the service provided by the electronic device 100 . By varying the rate, when the data transmission rate is less than or equal to the threshold speed, when the quality of transmitted or received data is better than the preset threshold quality, or when a predetermined service is not provided, the The data transfer rate can be made less restrictive depending on heat generation.

14 illustrates an operation process of the electronic device 100 according to an embodiment of the present invention in this case, and generates heat according to the transmission speed of data received by the electronic device 100 or transmitted from the electronic device 100 . It shows the operation process of changing the data transmission rate limit rate according to the relaxation.

Referring to FIG. 14 , the modem 270 of the electronic device 100 according to an embodiment of the present invention may first detect the temperature of the electronic device 100 ( S1402 ). In this case, since FIG. 14 is a process applicable when data throttling, which is one of the heat relief steps, is performed, hereinafter, it is assumed that the temperature detected in step S1402 is a temperature equal to or higher than the temperature condition at which the data throttling starts. do it with

Then, the modem 270 may detect whether the temperature detected in step S1402 satisfies a preset temperature condition for data throttling (S1404). That is, when the temperature detected in step S1402 exceeds a preset temperature condition for the data throttling, the modem 270 determines that heat should be relieved according to the heating method according to the next heat alleviation step (S1414) and the operation process of FIG. 14 may be terminated.

On the other hand, when the temperature detected in step S1402 satisfies the temperature condition preset for the data throttling, that is, when the detected temperature is less than the temperature for the start of the next heat alleviation step, the modem 270 performs the step S1402 It is possible to detect a data transfer rate limit value or a data transfer rate limit rate corresponding to the detected temperature (S1406). And it is possible to detect the transmission rate of data received by the electronic device 100 or transmitted from the electronic device 100 (S1408).

When the data transmission rate is detected in step S1408, the modem 270 may detect whether the detected data transmission rate is less than or equal to a preset threshold speed (S1410). In addition, when the detected data transmission rate is less than or equal to the preset threshold speed, the modem 270 may reduce the data transmission rate limit value or the data transmission rate limit rate detected in step S1406 ( S1412 ).

In this case, the modem 270 may reduce the limit value or the limit rate differently according to the data transmission rate detected in step S1408. That is, as the data transmission rate detected in step S1408 is lower, the limit value or the limit rate can be further reduced. Therefore, as the data transfer rate is lower, the limit width of the data transfer rate corresponding to the temperature increase due to the heat of the electronic device 100 may be smaller.

Meanwhile, the process described with reference to FIG. 14 may be repeatedly performed according to a preset period. In this case, step S1408 may be an average value of the detection results of a plurality of data transmission rates detected during the preset period.

Meanwhile, in the above description, the configuration for reducing the limit of the data transfer rate according to the temperature has been described according to the result of detecting the data transfer rate. Of course, it can be applied even when a preset service is not provided.

For example, step S1408 of FIG. 14 may be a step of detecting the quality of transmitted or received data instead of the data transmission rate. In addition, the step S1410 may be a step of detecting whether the detected data quality is better than a threshold quality. In this case, the step S1412 may be a step of reducing the data transfer rate limit value or the data transfer rate limit rate detected in the step S1406 according to the quality of the detected data.

Similarly, the step S1412 may be a step of differently reducing the limit value or the limit rate according to the detected data quality. That is, the better the quality of the data detected in step S1408, the greater the limit value or the limit rate can be reduced. Therefore, the better the quality of transmitted or received data, the smaller the limit of the data transmission rate corresponding to the temperature increase due to the heat of the electronic device 100 may be smaller.

Similarly, step S1408 of FIG. 14 may be a step of detecting services provided by the electronic device 100 . In addition, the step S1410 may be a step of detecting whether a predetermined specific service is provided. In this case, the step S1412 may be a step of reducing the data transfer rate limit value or the data transfer rate limit rate detected in the step S1406 according to whether the predetermined specific service is being provided. In this case, when the predetermined specific service is not provided, the data transmission rate limit value or the data transmission rate limit rate may be reduced.

Meanwhile, the step S1410 may further include restoring the reduced data transfer rate limit value or the reduced data transfer rate limit rate (not shown). For example, when the process of FIG. 14 is repeatedly performed according to a preset period as described above, the data transfer rate limit value or the data transfer rate limit rate is reduced according to step S1410 performed in the previous period, and the process is performed again. As a result of the detection in step S1410 of FIG. 14, if the data transmission rate exceeds the threshold speed, the quality of transmitted and received data is less than a preset threshold quality, or if a service designated in advance as requiring a high data transmission rate is provided , it is possible to restore the data transfer rate limit value or data transfer rate limit rate reduced in the last period to the initial value. Then, the data transfer rate limit value or the data transfer rate limit rate is not reduced, that is, the data transfer rate may be limited according to the data transfer rate limit value or the limit rate corresponding to the temperature of the electronic device 100 detected in step S1406. have.

Further scope of applicability of the present invention will become apparent from the following detailed description. However, it should be understood that the detailed description and specific embodiments such as preferred embodiments of the present invention are given by way of illustration only, since various changes and modifications within the spirit and scope of the present invention may be clearly understood by those skilled in the art.
