Description

Electronic device and method for controlling transmission power of electronic device supporting dual access

Various embodiments relate to an electronic device and a method of controlling transmission power of an electronic device supporting dual connectivity.

As the use of portable terminals that provide various functions has become widespread due to the development of mobile communication technology, efforts are being made to develop 5G communication systems to meet the increasing demand for wireless data traffic. In order to achieve a high data transmission rate, the 5G communication system uses a higher frequency band (e.g. For example, implementation in the 25 to 60 GHz band) is being considered.

As a method of implementing 5G communication, SA (stand alone) method and NSA (non-stand alone) method are being considered. Among these, the NSA method may include the EN-DC (LTE NR - Dual Connectivity) method that uses a new radio (NR) system together with the existing LTE system. In the NSA scheme, the user terminal can use not only the eNB of the LTE system, but also the gNB of the NR system. A technology that enables a user terminal to use heterogeneous communication systems can be named dual connectivity.

Dual connectivity was first proposed by 3GPP (3rd generation partnership project) release-12, and in the first proposal, dual connectivity using the 3.5 GHz frequency band as a small cell in addition to the LTE system was proposed. The EN-DC method of 5G can be implemented by using the dual connectivity proposed by 3GPP release-12 and release-15, using LTE network communication as a master node and NR network communication as a secondary node.

Electronic devices (eg, user equipment (UE)) may have limitations in output power. For example, the electronic device may set a threshold of output power according to the UE power class of the electronic device (e.g., UE maximum output power of 3GPP technical specification (TS) 38.101) (hereinafter referred to as Pemax). ) and can be set to not generate output power exceeding the threshold. If multiple radio access technologies (RATs) are used simultaneously (e.g., ENDC or NEDC), the electronic device may be set to prevent the total output power of the multiple RATs from exceeding a threshold. Dynamic power sharing (DPS) may refer to a pair of various output power values for each RAT that prevents the sum of output power by a plurality of RATs from exceeding a threshold.

For example, when using ENDC, the maximum output power available in NR communication may be limited by the electronic device's output power in LTE communication. In various embodiments, when an electronic device operates in ENDC, the output power of LTE communication may be set lower than the maximum power when communicating only through LTE to secure a margin for NR communication. By doing this, the electronic device can secure more transmission power for NR communication by the secured margin when operating in ENDC. When the electronic device operates in ENDC, even when the NR transmission power is not high, the output power of the LTE communication is set lower than that of LTE communication alone as described above, so additional available power cannot be utilized. may occur. As electronic devices cannot use the available power to the maximum when communicating with LTE alone in an ENDC situation, the block error rate (BLER) increases or radio link failure (RLF) occurs on the LTE communication network operating as an anchor. It can happen.

An electronic device and a method of operating the same according to various embodiments provide, when the NR transmission power in an electronic device operating in ENDC is relatively low, the sum of the LTE transmission power by DPS and the NR transmission power does not violate the ENDC maximum power. , it is possible to provide a method of controlling transmission power of an electronic device that can additionally secure the maximum LTE transmission power and an electronic device that supports dual connectivity.

According to various embodiments, an electronic device includes a plurality of antennas and a communication processor connected to the plurality of antennas, wherein the communication processor has dual connectivity with a first communication network and a second communication network. Establish and transmit to the first communication network based on the first maximum power set in the signal transmitted to the first communication network in response to the dual connection and the first power-related information received from the first communication network. Confirming the first power of the signal, and based on the first power and the second maximum power of the electronic device set corresponding to the dual connectivity, set to the signal transmitted to the second communication network in response to the dual connectivity identify a third maximum power, and based on the third maximum power and second power-related information received from the second communication network, determine a second power of a signal to be transmitted to the second communication network, and perform the dual connection Set to reset the first maximum power based on the second maximum power and the second maximum power of the electronic device set correspondingly, and adjust the first power based on the reset first maximum power. can be

According to various embodiments, a method of operating an electronic device includes establishing dual connectivity with a first communication network and a second communication network; Based on the first maximum power set for the signal transmitted to the first communication network in response to the dual connection and the first power-related information received from the first communication network, the first power of the signal to be transmitted to the first communication network An operation of checking power, based on a second maximum power of the electronic device set in response to the dual connection and the first power, a third maximum power set in a signal transmitted to the second communication network in response to the dual connection.

Can include actions.

According to various embodiments, when the electronic device is operating in ENDC and the NR transmit power is relatively low, the sum of the LTE transmit power and the NR transmit power according to DPS is the LTE maximum transmittable without violating the ENDC maximum power. Additional power can be secured. While operating in ENDC, the electronic device can reduce BLER and RLF by additionally securing the maximum LTE power that can be transmitted.

After conversion, the IF signal can be transmitted to the third RFIC (226). The third RFIC 226 can convert the IF signal into a 5G Above6 RF signal. Upon reception, a 5G Above6 RF signal may be received from a second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and converted into an IF signal by a third RFIC 226. there is. The fourth RFIC 228 may convert the IF signal into a baseband signal so that the second communication processor 214 can process it.

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

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

According to one example, the antenna 248 may be formed as an antenna array including a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC 226, for example, as part of the third RFFE 236, may include a plurality of phase shifters 238 corresponding to a plurality of antenna elements. At the time of transmission, each of the plurality of phase converters 238 may convert the phase of the 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a 5G network) through the corresponding antenna element. . Upon reception, each of the plurality of phase converters 238 may convert the phase of the 5G Above6 RF signal received from the outside through the corresponding antenna element into the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device 101 and the outside.

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

It may include a network environment that transmits and receives control messages to and from the electronic device 101 through the core network 330 of .

According to various embodiments, in a DC environment, one of the LTE base stations 341 or the NR base stations 351 operates as a master node (MN) 310 and the other operates as a secondary node (SN) 320. can do. The MN 310 is connected to the core network 330 and can transmit and receive control messages. The MN 310 and the SN 320 are connected through a network interface and can transmit and receive messages related to wireless resource (eg, communication channel) management with each other.

According to various embodiments, the MN 310 may be comprised of an LTE base station 341, the SN 320 may be comprised of an NR base station 351, and the core network 330 may be comprised of an EPC 342. For example, control messages may be transmitted and received through the LTE base station 341 and the EPC 342, and user data may be transmitted and received through at least one of the LTE base station 341 or the NR base station 351.

According to various embodiments, the MN 310 may be composed of an NR base station 351, the SN 320 may be composed of an LTE base station 341, and the core network 330 may be composed of a 5GC 352. For example, control messages may be transmitted and received through the NR base station 351 and 5GC 352, and user data may be transmitted and received through at least one of the LTE base station 341 or the NR base station 351.

Referring to FIG. 3B, according to various embodiments, a 5G network may be composed of an NR base station 351 and 5GC 352, and may transmit and receive control messages and user data independently from the electronic device 101.

Referring to FIG. 3C, the legacy network and 5G network according to various embodiments can each independently provide data transmission and reception.

As described above, dual connectivity through the LTE base station 341 and the NR base station 351 may be referred to as EN-DC (E-UTRA new radio dual connectivity).

According to various embodiments, power transmitted from an electronic device (e.g., electronic device 101 of FIG. 1) may be set not to exceed a maximum transmission power level (MTPL). For example, when an electronic device operates as stand alone (SA), the maximum transmission power level may be determined as the minimum value among Pcmax, specific absorption rate (SAR) Max Limit, and Pemax. The Pcmax can be defined as the maximum power that can transmit a signal while ensuring the performance of the electronic device. Maximum power reduction (MPR) backoff and additional maximum power reduction (AMPR) backoff may be applied to the Pcmax. The Pemax is the maximum allowable power delivered by the base station to the terminal, and can be set differently depending on the power class. The SAR Max Limit can be defined as the maximum power that does not violate SAR. Additionally, the maximum power of the electronic device may be backed off by thermal mitigation (TM) or WLAN coexistence.

According to various embodiments, an electronic device may apply dynamic power sharing (DPS) to control transmission power not to exceed a maximum value when simultaneously transmitting a signal to an LTE network and an NR network in an ENDC environment. For example, an electronic device can use ENDC based on LTE and NR. In this case, LTE may be set to MCG, and NR may be set to SCG. Even when two RATs are used simultaneously, the electronic device can be set so that the sum of the output powers corresponding to the two RATs satisfies the maximum output power set in the electronic device or less. In this case, the output power of LTE communication, which is MCG, may be set preferentially, and the output power of NR communication, which is SCG, may be limited. For example, the electronic device may set a first size of the output power (P _LTE ) of LTE communication and set a second size of the output power (P _NR ) of NR communication. The electronic device, when the sum of both output powers exceeds the maximum output power set for the electronic device, maintains the first magnitude of the output power (P _LTE ) of the LTE communication, while maintaining the first magnitude of the output power (P _NR ) of the NR communication. 2 size can be reduced to a third size. The sum of the first size and the third size may be less than or equal to the maximum output power set in the electronic device.

For example, if the output power of LTE communication (P _LTE ) is 23dBm, the maximum output power of NR communication according to DPS (P _{max_NR_DPS} ) may be 17dBm, in this case 23dBm (200mW) and 17dBm (50mW). The sum of 24dBm can be limited to within the maximum output power within the tolerance.

According to various embodiments, during LTE communication, an electronic device may transmit a transmission signal (eg, a physical shared channel (PUSCH) signal or a physical control channel (PUCCH) signal). For example, when located in a strong electric field, the electronic device may set the transmission power of the PUCCH of LTE communication to a relatively low level (e.g., -10 dBm). For example, the electronic device may set the transmission power of the PUCCH of LTE communication for subframe (i) according to Equation 1 below.

In Equation 1 above, P _CMAX is the maximum power that can be transmitted while ensuring the performance of the electronic device 101. P _{O_PUCCH} is the sum of P _{O_NOMINAL_PUCCH} (parameter specified by the cell) and P _{O_UE_PUCCH} (parameter specified by the electronic device). Path loss (PL) is the downlink path loss measured in an electronic device. h(n _CQI ,n _HARQ ) is a value according to the PUCCH format, n _CQI is the amount of information according to the channel quality indication (CQI), and n _HARQ is a hybrid automatic retransmission request. This is the number of repeat request (HARQ) bits. Δ _{F_PUCCH} (F) is a value for the PUCCH transport format F and can be transmitted to the electronic device through an RRC message. g(i) is a value that can be adjusted by DCI (downlink control information) from the base station. At least some of the parameters for <Equation 1> may follow, for example, 3GPP TS 36.213. The electronic device may set the smaller value among the sum of P _CMAX , P _{O_UE_PUCCH} , PL, h(n _CQI , n _HARQ ), Δ _{F_PUCCH} (F), and g(i) as the transmission power of PUCCH of LTE communication. . In a situation where an electronic device is located in a strong electric field, the transmission power of PUCCH of LTE communication can be maintained at a relatively low value.

Electronic devices according to various embodiments may set the transmission power of the PUSCH of LTE communication for subframe (i) according to Equation 2 below.

P _CMAX is the maximum power that can be transmitted while ensuring the performance of the electronic device 101. M _PUSCH (i) is the number of resource blocks allocated to the electronic device. P _{O_PUSCH} (j) is the sum of P _{O_NOMINAL_PUSCH} (j) (parameter specified by the cell) and P _{O_UE_PUSCH} (j) (parameter specified by the electronic device). PL is the downlink path loss measured in the electronic device. The scaling factor (α(j)) may be determined at the upper layer by considering the path loss mismatch between the uplink channel and the downlink channel. Δ _TF (i) is a modulation and coding scheme (MCS) compensation parameter or a transport format (TF) compensation parameter. f(i) is a value adjusted by DCI (downlink control information) from the base station after initial setting. The electronic device determines the smaller of P _CMAX and the sum of M _PUSCH (i), P _{O_PUSCH} (j), the product of scaling factor (α(j)) and PL, Δ _TF (i), and f(i). It can be set to the transmission power of PUSCH of LTE communication. At least some of the parameters for <Equation 2> may follow, for example, 3GPP TS 36.213. Even in a situation where the electronic device is located in a strong electric field, if the number of resource blocks (M _PUSCH (i)) allocated to the electronic device is relatively large, the transmission power of the PUSCH of LTE communication can maintain a relatively high value. .

According to various embodiments, when an electronic device operates in ENDC, the maximum output power of NR communication according to DPS (P _{max_NR_DPS} ) (e.g., 17 dBm) corresponds to the transmission power of PUSCH of LTE communication (e.g., 23 dBm). can be set. In various embodiments described later, when an electronic device simultaneously transmits a signal to an LTE network and an NR network in an ENDC environment, DPS can be applied to control the transmission power not to exceed the maximum limit.

4A and 4B are diagrams showing transmission power settings in DPS of an electronic device according to various embodiments.

According to various embodiments, the electronic device determines the maximum transmission power to be transmitted to the LTE network in an ENDC situation by the smaller of the calculated value of <Equation 1> or <Equation 2> and the ENDC LTE maximum power (ENDC LTE max power). It can be determined by value. For example, when the transmission power calculated by the above-described <Equation 1> or <Equation 2> exceeds the ENDC LTE maximum power set in response to the LTE network in an ENDC situation, the electronic device transmits the signal to be transmitted to the LTE network. Actual transmission power (hereinafter referred to as LTE power) can be set to be limited to the ENDC LTE maximum power.

Referring to FIGS. 4A and 4B, the size of the entire block represents the maximum power that an electronic device can transmit in an ENDC situation (hereinafter referred to as 'ENDC max power'). As shown in FIG. 4A, the ENDC LTE maximum power may be set smaller than the ENDC maximum power (eg, total block size). For example, the electronic device can guarantee the minimum NR power in an ENDC situation by setting the ENDC LTE maximum power to be less than the ENDC maximum power.

According to various embodiments, the ENDC NR maximum power of the signal to be transmitted to the NR network is determined by applying DPS to the actual LTE power to be transmitted at the ENDC maximum power (e.g., total block size) as shown in FIG. 4B. It can be set to the remaining power after subtraction. Since DPS is applied to the ENDC NR maximum power, it may also be referred to as NR DPS maximum power (DPS max power). The electronic device calculates the transmission power of the signal to be transmitted to the NR network (hereinafter referred to as NR power) using the above-described <Equation 1> or <Equation 2>, and the calculated NR power is In the ENDC situation, it can be set not to exceed the ENDC NR maximum power (or NR DPS maximum power) set considering the LTE power.

According to various embodiments, the power control period of LTE and/or NR may be determined by transmission time interval (TTI). For example, the TTI period of LTE may be in units of subframes, and the TTI period of NR may be in units of slots.

According to various embodiments, in operation 511, the LTE power determination module 501 of the electronic device 101 determines the DCI included in a signal received from an LTE base station (e.g., eNB (e.g., MN 310 in FIG. 3A)). Based on , LTE requested power can be determined. For example, the LTE requested power may be determined based on the above-described <Equation 1> or <Equation 2>. In operation 515, the LTE power determination module 501 of the electronic device 101 may transmit the determined LTE requested power to the power management module 503. According to various embodiments, the LTE power determination module 501 further sends transmission information (Tx information (e.g., channel, modulation method, or bandwidth information) along with the determined LTE request power to the power management module 503. Can be transmitted. The power management module 503 of the electronic device 101 determines ENDC LTE based on at least one of information (e.g., LTE request power, transmission information), SAR status, or TM information received from the LTE power determination module 501. The maximum power can be determined. For example, the ENDC LTE maximum power may be determined as the minimum value among Pcmax, Pemax, SAR Max, and ENDC LTE NR DPS maximum power, but is not limited to this.

According to various embodiments, in operation 517, the power management module 503 of the electronic device 101 may transmit information about the determined ENDC LTE maximum power to the LTE power determination module 501. The LTE power determination module 501 checks the ENDC LTE maximum power information received from the power management module 503, and determines the LTE power so that the LTE requested power does not exceed the ENDC LTE maximum power in operation 521. can be decided. In operation 523, the LTE power determination module 501 may transmit the determined LTE power to the power management module 503.

According to various embodiments, at operation 513, the NR power determination module 502 of the electronic device 101 determines the DCI included in the signal received from the NR base station (e.g., gNB (e.g., SN 320 in FIG. 3A)). Based on NR requested power (NR requested power) can be determined. For example, the NR requested power may be determined based on the above-described <Equation 1> or <Equation 2>. In operation 519, the NR power determination module 502 of the electronic device 101 may transmit the determined NR requested power to the power management module 503.

Can be transmitted. At operation 525, the power management module 503 calculates the ENDC NR maximum power (e.g., NR DPS maximum power) based on the ENDC maximum power and LTE power as described above in FIGS. 4A and 4B, and the NR power determination module The calculated ENDC NR maximum power may be transmitted to 502. In operation 527, the NR power determination module 502 determines that the transmission power (NR power) of the signal to be transmitted to the NR network calculated by the above-described <Equation 1> or <Equation 2> in the ENDC situation. It can be set not to exceed the ENDC NR maximum power (or NR DPS maximum power) set in consideration of the LTE power. In operation 529, the NR power determination module 502 may transmit the set NR power to the power management module 503. The power management module 503 may control the transmission power of a signal to be transmitted to the LTE network and a signal to be transmitted to the NR network based on the determined LTE power and NR power.

FIG. 6 is a diagram illustrating timing for determining transmission power according to various embodiments. Referring to FIG. 6, when the LTE base station (eNodeB) and the NR base station (gNodeB) are synchronized and the timing is the same, the LTE power in each subframe and the NR power in each slot can be determined as shown. Meanwhile, the subframes on the LTE side and the slots on the NR side in FIG. 6 may logically correspond to each other, but may not logically correspond to each other depending on implementation. For example, the index of the subframe on the LTE side and the slot index on the NR side may not correspond to each other. In FIG. 6, the subframes on the LTE side and the slots on the NR side may physically correspond to each other, but depending on implementation, they may not physically correspond to each other. For example, the start and end point for segmenting one subframe on the LTE side may not be the same as the start and end point for segmenting one slot on the NR side.

According to various embodiments, in operation 601, the LTE power determination module 501 may transfer the LTE requested power to the power management module 503. In operation 602, the power management module 503 may determine the ENDC NR maximum power (e.g., NR DPS maximum power) that satisfies the DPS, and transmit the determined ENDC NR maximum power to the NR power determination module 502. In operation 603, the NR power determination module 502 may determine the transmit power (NR power) of NR slot 6 based on the ENDC NR maximum power received from the power management module 503. Meanwhile, in FIG. 6, one subframe 6 on the LTE side is described as corresponding to one slot 6 on the NR side, but this is an example and a plurality of NR side slots correspond to one subframe on the LTE side. Those skilled in the art will understand that this may be possible.

According to various embodiments, at operation 604, the power management module 503 may convey the LTE maximum power of LTE subframe 6 to the LTE power determination module 501. In operation 605, the LTE power determination module 501 may determine the transmission power (LTE power) of LTE subframe 6 based on the LTE maximum power of LTE subframe 6 received from the power management module 503.

FIG. 7 is a diagram illustrating timing for determining transmission power according to various embodiments. Referring to FIG. 7, when the LTE base station (eNodeB) and the NR base station (gNodeB) are not synchronized and the timing is different, the LTE power in each subframe and the NR power in each slot can be determined as shown. . For example, the subframe index on the LTE side and the subframe index on the NR side do not logically correspond and may not be synchronized. For example, the length of the subframe on the LTE side and the length of the slot on the NR side may be physically different and therefore not synchronized. For example, based on differences in processing times between at least some entities of the electronic device 101, synchronization may occur, and there are no limitations to the causes of non-synchronization other than the examples described above.

According to various embodiments, in operation 701, the LTE power determination module 501 may transfer the LTE requested power of LTE subframe 5 to the power management module 503.

In operation 706, the LTE power determination module 501 may determine the transmission power (LTE power) of LTE subframe 6 based on the LTE maximum power of LTE subframe 6 received from the power management module 503.

FIGS. 8A and 8B are diagrams illustrating transmission power settings in DPS of an electronic device according to various embodiments. Referring to FIG. 8A, the electronic device may set the LTE maximum power in the ENDC situation (eg, ENDC LTE maximum power) to be lower than the LTE maximum power in the SA situation (LTE only max power). For example, if the LTE power is relatively too high and becomes equal to the ENDC maximum power (e.g., total block size), the NR signal may not be transmitted because there is no transmission power margin for NR. Considering this, the electronic device may set the LTE maximum power in the ENDC situation to be lower than the LTE maximum power in the SA situation, as shown in FIG. 8A.

According to various embodiments, when an electronic device operates in ENDC where the LTE frequency band is the B2 band and the NR frequency band is the N5 band, the maximum transmission power can be set as follows. For example, when B2+N5 ENDC maximum power is 24.5dBm, and B2 maximum power is 23.5dBm in SA mode and 23dBm in ENDC, N5 maximum power can be set to 24.5dBm. According to various embodiments, when an electronic device operates in ENDC where the LTE frequency band is the B5 band and the NR frequency band is the N2 band, the maximum transmission power can be set as follows. For example, when B5+N2 ENDC maximum power is 24.5dBm, and B5 maximum power is 24.5dBm in SA mode and 23dBm in ENDC, N2 maximum power can be set to 23.5dBm.

The above two examples can be shown in <Table 1> below.

	LTE only	ENDC LTE	difference
B2	23.5dBm	23dBm	-0.5dB
B5	24.5dBm	23dBm	-1.5dB

Referring to FIG. 8B, according to various embodiments, when the NR power is not relatively high, the ENDC LTE maximum power is set lower than the LTE maximum power in SA, so a margin may occur in the ENDC LTE maximum power. Accordingly, the electronic device may not be able to utilize LTE power as much as the margin shown in FIG. 8B. For example, assuming that the actual power (e.g., NR power) transmitted by the electronic device to the NR network is 10 dBm, the LTE power may be limited according to the limit of the ENDC LTE maximum power as shown in Table 2 below.

	ENDC maximum power	NR power	ENDC LTE maximum power	LTE capable power	margin
B2+N5	24.5dBm	10dBm	23dBm	23.5dBm	0.5dB
B5+N2	24.5dBm	10dBm	23dBm	24.3dBm	1.3dB
B5+N2	24.5dBm	No power	23dBm	24.5dBm	1.5dB

Referring to <Table 2> above, although there is a power margin for LTE to transmit additionally, the block error rate (BLER) increases due to being limited by the preset ENDC LTE maximum power, or the radio link rate (RLF) increases. The possibility of failure may increase. In various embodiments described later, when the NR power is relatively low as described above and a margin occurs in the ENDC LTE maximum power, the preset ENDC LTE maximum power is readjusted based on the margin ( For example, in various embodiments described later, when an electronic device applies DPS in an ENDC situation, the sum of LTE power and NR power does not violate the ENDC maximum power, and the transmission power of NR is relative. By calculating the LTE maximum power that can be transmitted when low, the BLER of the LTE transmission signal that operates as an anchor in the ENDC situation is increased by increasing the LTE transmission power to the same level as the LTE maximum power in the SA situation (e.g., LTE only maximum power). In various embodiments described later, the timing of determining the transmission power of NR during DPS operation may vary depending on the SCS (subcarrier spacing) setting of NR, for example, LTE power at least 1 subframe before 30khz. Figures 9A and 9B are diagrams showing transmission power settings in DPS of an electronic device according to various embodiments. Referring to Figures 9A and 9B, as described above, the ENDC LTE maximum power is determined in the SA situation. may be set to be less than the LTE maximum power (LTE only max power), and thus a margin may occur. According to various embodiments, when the NR power is relatively small and a margin as illustrated in FIG. 8B occurs, FIG. As shown in 9b, the ENDC LTE maximum power can be readjusted to increase by the LTE maximum power (LTE only max power) in the SA situation.

According to various embodiments, the LTE power determination module 501 may be set to request additional power from the power management module 503 when the LTE power is set to the ENDC LTE maximum power and the BLER is above a certain level.

According to various embodiments, in operation 1003, the NR power determination module 502 of the electronic device 101 determines the DCI included in the signal received from the NR base station (e.g., gNB (e.g., SN 320 in FIG. 3A)). Based on NR requested power (NR requested power) can be determined. For example, the NR requested power may be determined based on the above-described <Equation 1> or <Equation 2>. In operation 1009, the NR power determination module 502 of the electronic device 101 may transmit the determined NR requested power to the power management module 503. According to various embodiments, the NR power determination module 502 further sends transmission information (Tx information) (e.g., channel, modulation method, or bandwidth information) along with the determined NR request power to the power management module 503. Can be transmitted.

You can set the maximum power (new ENDC LTE max power). For example, if the NR power determined in the NR power determination module 502 is less than the ENDC NR maximum power (e.g., NR DPS maximum power), it is determined that a margin has occurred, and the ENDC LTE maximum power is adjusted upward in consideration of the margin.
