Description

Electronic device for controlling transmission power and method of operation thereof

[0001] Embodiments of the present disclosure relate to an electronic device for controlling transmission power and a method of operating the same.

[0002] To meet the increasing demand for wireless data traffic since the commercialization of 4G communication systems, efforts are being made to develop 5G communication systems. For this reason, 5G communication systems are also called "Beyond 4G Network" or "Post LTE" communication systems. To achieve relatively high data rates, 5G communication systems are being considered for implementation in sub-6 GHz bands (e.g., approximately 3.5 GHz bands) or higher frequency bands (e.g., approximately 28 GHz or 39 GHz bands). To mitigate radio path loss and increase the transmission range of radio waves, beamforming, massive MIMO (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antenna technologies are being discussed for 5G communication systems.

[0003] The above information may be provided as background information to aid in understanding this document. None of the above is claimed to be prior art related to this document or can be used to determine prior art.

[0004] An electronic device (e.g., a user equipment (UE)) of a wireless communication system can dynamically set a transmission power based on a power control signal (e.g., a transmission power control (TPC) command) received from a network device (e.g., an E-UTRAN node B (eNB) or a next generation node B (gNB)). For example, the electronic device can update (or set) a transmission power control variable (e.g., TPC accumulation) based on the power control signal received from the network device. The electronic device can set a transmission power to be used for transmitting data to the network device based on the updated transmission power control variable.

[0005] The electronic device may unnecessarily increase its transmission power by continuously increasing its transmission power control variable based on a power control signal received from a network device regardless of the channel condition with the network.

[0006] Embodiments of the present disclosure disclose devices and methods for controlling transmission power in an electronic device.

[0007] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present disclosure belongs from the description below.

According to one embodiment, the instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to limit an increase in a transmission power control variable by a TPC signal from the network indicating an increase in the transmission power control variable when a specified condition is satisfied while the electronic device is connected to the network. According to one embodiment, the instructions, when individually and / or collectively executed by the at least one processor, may cause the electronic device to transmit at least one signal at a transmission power based on a transmission power control variable whose increase by the TPC signal is limited.

One or more processors may be configured to perform various functions individually and / or collectively in a distributed manner. When "processor," "at least one processor," and "one or more processors" are described as being configured to perform multiple functions, the terms "processor," "at least one processor," and "one or more processors" used in one embodiment of this document include, but are not limited to, situations where one processor performs some of the recited functions, another processor performs other of the recited functions, and situations where a single processor can perform all of the recited functions. Furthermore, the at least one processor may include a combination of processors that perform various functions in a distributed manner. At least one processor may execute program instructions for performing various functions. The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first network (292) and support legacy network communication through the established communication channel. In one embodiment, the first network (292) may be a legacy network, including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may include various processing circuits and / or a plurality of processors. For example, a processor used in the present invention (or claims) may include at least one processor including various processing circuits. One or more processors may be configured to perform various functions individually and / or collectively in a distributed manner.When "processor," "at least one processor," and "one or more processors" as used in one embodiment of this document are described as being configured to perform multiple functions, this includes, but is not limited to, a situation where one processor performs some of the cited functions and another processor performs other of the cited functions, and a situation where a single processor can perform all of the cited functions. In addition, at least one processor may include a combination of processors that perform various functions in a distributed manner. At least one processor may execute program instructions for performing various functions. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second network (294), and support 5G network communication through the established communication channel. According to one embodiment, the second network (294) may be a 5G network (e.g., NR (new radio)) defined by 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may establish a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second network (294), and support 5G network communication through the established communication channel. According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package. According to one embodiment, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190).

[0058] In one embodiment, the first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted via the second network (294) may be changed to be transmitted via the first network (292).

[0059] In this case, the first communication processor (212) can receive transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data to and from the second communication processor (214) through an inter-processor interface. For example, the inter-processor interface can be implemented as a universal asynchronous receiver / transmitter (UART) (e.g., high speed-UART (HS-UART)) or a peripheral component interconnect bus express (PCIe) interface, but there is no limitation on the type thereof. For example, the first communication processor (212) and the second communication processor (214) can exchange control information and packet data information using a shared memory. For example, the first communication processor (212) can transmit and receive various information, such as sensing information, information on output strength, and RB (resource block) allocation information, with the second communication processor (214).

[0060] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., an application processor (AP)). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., an application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. For example, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., an application processor) using a shared memory. In one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented within a single chip or a single package. In one embodiment, the first communication processor (212) or the second communication processor (214) may be formed within a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190).

[0061] The first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0062] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0063] The third RFIC (226) can convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second network (294) (e.g., 5G network) via an antenna (e.g., antenna (248)) and preprocessed via the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0064] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separate from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0065] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, 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 corresponding multiple bands.

[0066] In one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the lower surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the upper surface) of the second substrate, thereby forming the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications due to transmission line transmission. As a result, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., the 5G network).

[0067] In one embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0068] The second network (294) (e.g., a 5G network) may operate independently (e.g., stand-alone (SA)) or connectedly (e.g., non-stand-alone (NSA)) from the first network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., new radio (NR) protocol information) may be stored in the memory (130) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0069] FIG. 3 is a block diagram of an electronic device for controlling transmission power according to one embodiment. For example, the electronic device (101) of FIG. 3 may be at least partially similar to the electronic device (101) of FIG. 1 or FIG. 2 or may further include other embodiments of the electronic device.

[0070] According to one embodiment referring to FIG. 3, the electronic device (101) may include at least one of a processor (300), a communication circuit (310), and a memory (320). According to one embodiment, the processor (300) may be substantially the same as the processor (120) (e.g., a communication processor) of FIG. 1 or 2, or may be included in the processor (120). The communication circuit (310) may be substantially the same as the wireless communication module (192) of FIG. 1 or 2, or may be included in the wireless communication module (192). The memory (320) may be substantially the same as the memory (130) of FIG. 1 or 2, or may be included in the memory (130). For example, the processor (300) may be operatively, functionally, and / or electrically connected to at least one of the communication circuit (310) or the memory (320). For example, the processor (300) may include at least one processor including a processing circuit.

[0071] According to one embodiment, when the processor (300) is connected to a network, the processor (300) may set the transmission power of the electronic device (101) based on a power control signal received from the network. For example, the processor (300) may set (or update) a transmission power control variable (e.g., a transmission power control variable or a transmission power control parameter) based on the power control signal received from the network. The processor (300) may set (or update) the transmission power of the electronic device (101) based on the transmission power control variable. For example, the transmission power control variable may include an accumulated value of a variable (or value) (e.g., -1, 0, 1, or 3) for controlling the transmission power included in the power control signal. For example, the transmission power control variable may be decreased, maintained, or increased based on a variable for controlling the transmission power included in the power control signal. For example, a power control signal can be received (or acquired) as a transmission power control (TPC) command, included in a downlink control indicator (DCI) of a specified format.

[0072] According to one embodiment, the processor (300) may continuously or periodically check at least one of a channel state or a channel change rate with the network while connected to the network. For example, the channel state may include a channel state of DL (downlink) and / or UL (uplink). For example, the channel state may include at least one of RSSI (received signal strength indication), RSRQ (reference signal received quality), RSRP (reference signal received power), SNR (signal to noise ratio), SINR (signal to interference and noise ratio), QoS (quality of service), BLER (block error rate), retransmission rate, or BER (bit error rate). For example, the state of being connected to the network may include an RRC (radio resource control) connected state.

[0073] According to one embodiment, the processor (300) may determine whether a specified first update condition related to a transmission power control variable is satisfied while connected to a network. For example, the processor (300) may determine whether the specified first update condition related to the transmission power control variable is satisfied based on at least one of a channel state with the network, a channel change rate with the network, or a power mode setting variable. For example, the processor (300) may determine that the specified first update condition related to the transmission power control variable is satisfied when the channel state with the network satisfies the specified channel state condition, the channel change rate with the network satisfies the specified channel change condition, and the power mode setting variable exceeds a specified first reference value. For example, the channel change rate may include a change amount of a channel state with the network measured periodically or continuously for a specified first time period. For example, the power mode setting variable may include an accumulated value (or sum) of a variable for controlling the transmission power included in a specified number of signals for increasing or decreasing the transmission power (or the transmission power control variable) received at a point in time prior to the current point in time among power control signals (e.g., TPC) received from the network. For example, a state satisfying a specified channel state condition may include a state in which the channel state with the network is equal to or greater than a specified reference channel state (e.g., a medium electric field and / or a strong electric field). For example, a state satisfying a specified channel change condition may include a state in which a channel change rate with the network is lower than a specified reference change rate.

[0074] For example, the processor (300) may determine that a specified first update condition related to a transmission power control variable is not satisfied when a channel state with a network does not satisfy a specified channel state condition, a channel change rate with a network does not satisfy a specified channel change condition, or a power mode setting variable is less than or equal to a specified first reference value. For example, a state of not satisfying a specified channel state condition may include a state in which a channel state with a network is less than a specified reference channel state (e.g., a weak electric field and / or a medium electric field). For example, a state of not satisfying a specified channel change condition may include a state in which a channel change rate with a network is greater than or equal to a specified reference change rate.

[0075] According to one embodiment, the processor (300) may selectively update the transmission power control variable based on a power control signal received from the network, if it is determined that a specified first update condition related to the transmission power control variable is satisfied. For example, the selective update of the transmission power control variable may include a state in which the transmission power control variable is decreased or maintained based on a variable for controlling the transmission power included in the power control signal (e.g., -1 or 0), but an increase based on a variable for controlling the transmission power included in the power control signal (e.g., 1 or 3) is limited.

[0076] For example, if the processor (300) determines that a specified first update condition related to a transmission power control variable is satisfied, the processor (300) may generate a second transmission power control variable that operates independently of the first transmission power control variable. For example, the second transmission power control variable may include the same value as the first transmission power control variable as an initial value. For example, the first transmission power control variable may represent a transmission power control variable for controlling the transmission power of the electronic device (101) before a situation in which the specified first update condition related to the transmission power control variable is satisfied. For example, the second transmission power control variable may represent a transmission power control variable for controlling the transmission power of the electronic device (101) after a situation in which the specified first update condition related to the transmission power control variable is satisfied.

[0077] For example, when the processor (300) receives a power control signal from the network through the communication circuit (310), the processor (300) may update the first transmission power control variable and / or the second transmission power control variable based on the power control signal. For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal. For example, the second transmission power control variable may be decreased or maintained based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal when a specified first update condition related to the transmission power control variable is satisfied, and an increase based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal may be limited.

[0078] For example, if the second transmission power control variable updated (e.g., maintained or decreased) based on the power control signal is smaller than the reference transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the reference transmission power control variable. For example, the second transmission power control variable may be additionally updated to the same value as the reference transmission power control variable. For example, the reference transmission power control variable may include an average value of the first transmission power control variable confirmed during a specified second time period prior to a time point at which a specified first update condition related to the transmission power control variable is determined to be satisfied.

[0079] For example, if the processor (300) determines that the difference between the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable and the first transmission power control variable satisfies a designated second update condition related to the transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the first transmission power control variable and the designated third reference value. For example, a state of satisfying the designated second update condition related to the transmission power control variable may include a state in which the difference between the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable and the first transmission power control variable exceeds the designated third reference value. For example, the second transmission power control variable may be additionally updated (or set) based on the difference between the first transmission power control variable and the designated third reference value.

[0080] According to one embodiment, the processor (300) may set (or update) the transmission power of the electronic device (101) based on the second transmission power control variable. The processor (300) may control the communication circuit (310) to transmit at least one signal (or data) with the transmission power set (or updated) based on the second transmission power control variable.

[0081] According to one embodiment, the processor (300) may determine whether a third update condition related to the transmission power control variable is satisfied while a first update condition related to the transmission power control variable is satisfied. For example, when the processor (300) satisfies the first update condition related to the transmission power control variable, and the channel state with the network does not satisfy the specified channel state condition, or the channel change rate with the network does not satisfy the specified channel change condition, or the power mode setting variable exceeds a second reference value, the processor (300) may determine that the third update condition related to the transmission power control variable is satisfied. For example, the state of not satisfying the specified channel state condition may include a state in which the channel state with the network is lower than a specified reference channel state (e.g., weak electric field and / or medium electric field). For example, the state of not satisfying the specified channel change condition may include a state in which the channel change rate with the network is higher than a specified reference change rate.

[0082] For example, the processor (300) may determine that a specified third update condition related to a transmission power control variable is not satisfied when a channel state with a network satisfies a specified channel state condition, a channel change rate with the network satisfies a specified channel change condition, and a transmission mode setting variable is less than or equal to a specified second reference value. For example, a state that satisfies a specified channel state condition may include a state in which the channel state with the network is greater than or equal to a specified reference channel state (e.g., a medium electric field and / or a strong electric field). For example, a state that satisfies a specified channel change condition may include a state in which a channel change rate with the network is lower than a specified reference change rate.

[0083] According to one embodiment, when the processor (300) determines that a designated third update condition related to the transmission power control variable is satisfied, the processor (300) may update the transmission power control variable (e.g., the second transmission power control variable) based on a power control signal received from the network. For example, when the processor (300) generates a second transmission power control variable corresponding to the first transmission power control variable based on satisfaction of a designated first update condition related to the transmission power control variable, the processor (300) may update the first transmission power control variable and the second transmission power control variable based on a power control signal received from the network via the communication circuit (310). For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable for controlling the transmission power included in the power control signal (e.g., -1, 0, 1, or 3). For example, the second transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling the transmission power included in the power control signal, if it is determined that a specified third update condition related to the transmission power control variable is satisfied.

[0084] For example, if the second transmission power control variable updated (e.g., decreased) based on the power control signal is smaller than the minimum transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the minimum transmission power control variable. For example, the second transmission power control variable may be additionally updated to the same value as the minimum transmission power control variable. For example, the minimum transmission power control variable may include a minimum value of the transmission power control variable for the electronic device (101) to maintain a connection with the network.

[0085] According to one embodiment, the processor (300) may set (or update) the transmission power of the electronic device (101) based on the second transmission power control variable. The processor (300) may control the communication circuit (310) to transmit at least one signal (or data) with the transmission power set (or updated) based on the second transmission power control variable.

[0086] According to one embodiment, when the processor (300) determines that the specified first update condition related to the transmission power control variable is satisfied while the specified third update condition related to the transmission power control variable is satisfied, the processor (300) may selectively update the transmission power control variable based on a power control signal received from the network.

[0087] According to one embodiment, if there is a history of determining that a specified first update condition related to a transmission power control variable is satisfied while the connection with the network is maintained, the processor (300) may set (or update) the transmission power of the electronic device (101) based on the second transmission power control variable until the connection between the electronic device (101) and the network is released. For example, the processor (300) may stop (or limit) the use of the second transmission power control variable when the configuration of a physical uplink shared channel (PUSCH) by the network is changed. For example, the processor (300) may stop (or limit) the use of the second transmission power control variable when the serving network is changed. For example, the processor (300) may stop (or limit) the use of the second transmission power control variable when the RRC state with the network is switched to an RRC inactive state or an RRC idle state. For example, if the processor (300) determines that use of the second transmission power control variable is to be discontinued (or limited), the processor (300) may set (or update) the transmission power of the electronic device (101) using the first transmission power control variable based on the connection to the network. For example, the first transmission power control variable may include a transmission power control variable generated based on the connection to the network.

[0088] According to one embodiment, the processor (300) can dynamically set reference values ​​associated with a designated first update condition related to a transmission power control variable and / or a designated third update condition related to a transmission power control variable. For example, the reference values ​​associated with the designated first update condition related to the transmission power control variable and / or the designated third update condition related to the transmission power control variable can be dynamically set based on a channel condition with the network (e.g., strong or medium electric field), as shown in Table 1 below.

[0089] Channel Status NN1N2N3high (strong field)(SINR > 20dB & ulBLER < 10%)105220Mid (medium field)(SINR > 5dB & ulBLER < 20%)2010510

[0090] For example, N may represent a specified number for setting a power mode setting variable, N1 may represent a specified first reference value for determining a specified first update condition related to a transmission power control variable, N2 may represent a specified second reference value for determining a specified third update condition related to a transmission power control variable, and N3 may represent a specified third reference value for determining whether to additionally update the second transmission power control variable based on a difference value between the first transmission power control variable and the second transmission power control variable.

[0091] According to one embodiment, the communication circuit (310) may support wireless communication between the electronic device (101) and an external electronic device (e.g., the electronic device (102 or 104) of FIG. 1). For example, the communication circuit (310) may include an RFIC (e.g., the first RFIC (222), the second RFIC (224), the third RFIC (226), and / or the fourth RFIC (228) of FIG. 2) and an RFFE (e.g., the first RFFE (232), the second RFFE (234), the third RFFE (236), and / or the fourth RFFE (238) of FIG. 2) that process signals or data transmitted or received via wireless resources. As an example, the wireless communication may include cellular communication (e.g., long term evolution (LTE) and / or new radio (NR)).

[0092] According to one embodiment, the memory (320) may store various data used by at least one component (e.g., the processor (300) or the communication circuit (310)) of the electronic device (101). For example, the memory (320) may store various instructions that may be executed by the processor (300). For example, the instructions may be executed individually or collectively by the processor (300) (e.g., at least one processor).

[0093] According to one embodiment, if the electronic device (101) does not update the second transmission power control variable based on the designated third reference value in a state where a designated first update condition related to the transmission power control variable is satisfied, the electronic device (101) may update the second transmission power control variable based on the designated third reference value in a state where a designated third update condition related to the transmission power control variable is satisfied. For example, if a difference value between the second transmission power control variable updated based on the power control signal and the first transmission power control variable exceeds the designated third reference value in a state where the designated third update condition related to the transmission power control variable is satisfied, the processor (300) may update the second transmission power control variable based on the first transmission power control variable and the designated third reference value. For example, the second transmission power control variable may be updated (or set) based on a difference value between the first transmission power control variable and the designated third reference value.

[0094] According to one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1, 2 or 3) may include communication circuitry (e.g., wireless communication module (192) of FIG. 1 or 2 or communication circuitry (310) of FIG. 3), at least one processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) including processing circuitry, and a memory (e.g., memory (130) of FIG. 1 or 2 or memory (320) of FIG. 3) storing instructions. According to one embodiment, the instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to set a transmission power control variable (e.g., a first transmission power control variable) based on a transmission power control (TPC) signal (e.g., a power control signal) received from a network connected via the communication circuitry. According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may cause the electronic device to limit an increase in a transmit power control variable by a TPC signal from a network indicating an increase in the transmit power control variable when a first update condition specified while connected to the network is satisfied. According to one embodiment, the instructions, when executed individually or collectively by at least one processor, may cause the electronic device to transmit at least one signal at a transmit power based on a transmit power control variable (e.g., a second transmit power control variable) whose increase by the TPC signal is limited.

[0095] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to set a second transmission power control variable corresponding to a first transmission power control variable set based on a TPC signal received from the network when a specified first update condition is satisfied while connected to the network. According to one embodiment, the second transmission power control variable may be limited from increasing by the TPC signal while the specified first update condition is satisfied.

[0096] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to determine whether a first update condition specified in the first update condition is satisfied based on at least one of a channel state with the network, a channel change rate with the network, or a power mode setting variable while connected to the network.

[0097] According to one embodiment, the power mode setting variable may include an accumulated value of a specified number of TPC signals indicating an increase or decrease of the first transmit power control variable.

[0098] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to set a reference transmit power control variable based on an average value of a first transmit power control variable set based on a specified number of TPC signals if a specified first update condition is satisfied. According to one embodiment, the instructions, when executed individually or collectively by at least one processor, cause the electronic device to update a second transmit power control variable based on a reference transmit power control variable if a second transmit power control variable reduced based on a TPC signal is less than the reference transmit power control variable.

[0099] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to decrease a second transmit power control variable by a specified amount if a TPC signal received from a network includes a variable related to decreasing transmit power of the electronic device. According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to limit updating of the second transmit power control variable if a TPC signal received from a network includes a variable related to maintaining or increasing transmit power of the electronic device.

[0100] According to one embodiment, the memory can store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to increase, maintain, or decrease a first transmit power control variable based on a TPC signal, when selectively updating a second transmit power control variable based on the TPC signal.

[0101] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to update the second transmission power control variable based on the first transmission power control variable if a difference value between the first transmission power control variable and the second transmission power control variable satisfies a specified second update condition.

[0102] According to one embodiment, the memory may store instructions that, when executed individually or collectively by at least one processor, cause the electronic device to set a transmission power control variable based on a transmission power control signal received from a network when the electronic device determines that a specified first update condition is satisfied and a specified third update condition different from the specified first update condition is satisfied. According to one embodiment, the second transmission power control variable may be increased, maintained, or decreased based on the TPC signal when the specified third update condition is satisfied.

[0103] FIG. 4 is a flowchart (400) for controlling transmission power in an electronic device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 4 may be the electronic device (101) of FIG. 1, FIG. 2, or FIG. 3.

[0104] According to one embodiment referring to FIG. 4, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) may, in operation 401, obtain a power control signal from a network to which the electronic device (101) is connected. For example, the power control signal may be received (or obtained) as a transmission power control (TPC) command, included in a downlink control indicator (DCI) of a specified format.

[0105] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may set (or update) a transmission power control variable based on a power control signal obtained from a network in operation 403. For example, the transmission power control variable may include an accumulated value of a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal. For example, the transmission power control variable may be decreased, maintained, or increased based on a variable for controlling transmission power included in the power control signal. For example, when there is at least one signal (or data) to be transmitted to a network (or a network device), the processor (300) may control the communication circuit (310) to transmit at least one signal (or data) to the network (or the network device) at a transmission power set (or updated) based on the transmission power control variable.

[0106] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may, in operation 405, determine whether a specified first update condition related to a transmission power control variable is satisfied while connected to a network. For example, the processor (300) may continuously or periodically determine at least one of a channel state or a channel change rate with the network while connected to the network. For example, the channel state may include a channel state of a downlink (DL) and / or an uplink (UL). For example, the channel state may include at least one of a received signal strength indication (RSSI), a reference signal received quality (RSRQ), a reference signal received power (RSRP), a signal to noise ratio (SNR), a signal to interference and noise ratio (SINR), a quality of service (QoS), a block error rate (BLER), a retransmission rate, or a bit error rate (BER). For example, the state of being connected to a network may include a radio resource control (RRC) connected state.

[0107] For example, the processor (300) may determine whether a specified first update condition related to a transmission power control variable is satisfied based on at least one of a channel state with the network, a channel change rate with the network, or a power mode setting variable.

[0108] For example, the processor (300) may determine that a specified first update condition related to a transmission power control variable is satisfied when a channel state with a network satisfies a specified channel state condition, a channel change rate with the network satisfies the specified channel change condition, and a power mode setting variable exceeds a specified first reference value. For example, the channel change rate may include a change amount of a channel state with the network measured periodically or continuously for a specified first time period. For example, the power mode setting variable may include an accumulated value (or sum) of variables for controlling transmission power included in a specified number of signals for increasing or decreasing transmission power received at a time point prior to the current time point among power control signals received from the network. For example, a state satisfying a specified channel state condition may include a state in which the channel state with the network is equal to or greater than a specified reference channel state (e.g., a medium electric field and / or a strong electric field). For example, a state satisfying a specified channel change condition may include a state in which a channel change rate with the network is lower than a specified reference change rate.

[0109] For example, the processor (300) may determine that a specified first update condition related to a transmission power control variable is not satisfied when a channel state with a network does not satisfy a specified channel state condition, a channel change rate with a network does not satisfy a specified channel change condition, or a power mode setting variable is less than or equal to a specified first reference value. For example, a state of not satisfying a specified channel state condition may include a state in which a channel state with a network is less than a specified reference channel state (e.g., a weak electric field and / or a medium electric field). For example, a state of not satisfying a specified channel change condition may include a state in which a channel change rate with a network is greater than or equal to a specified reference change rate.

[0110] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) determines that a specified first update condition related to a transmission power control variable is satisfied (e.g., 'Yes' in operation 405), in operation 407, the electronic device may selectively update a transmission power control variable to be used for setting the transmission power of the electronic device (101) based on a power control signal acquired from the network. For example, the selective update of the transmission power control variable may include a state in which the transmission power control variable is decreased or maintained based on a variable for controlling the transmission power included in the power control signal (e.g., -1 or 0), but an increase based on a variable for controlling the transmission power included in the power control signal (e.g., 1 or 3) is limited.

[0111] For example, if the processor (300) determines that a specified first update condition related to a transmission power control variable is satisfied, the processor (300) may generate a second transmission power control variable that operates independently of the first transmission power control variable. For example, the second transmission power control variable may include the same value as the first transmission power control variable as an initial value. For example, the first transmission power control variable may represent a transmission power control variable for controlling the transmission power of the electronic device (101) before a situation in which the specified first update condition related to the transmission power control variable is satisfied. For example, the second transmission power control variable may represent a transmission power control variable for controlling the transmission power of the electronic device (101) after a situation in which the specified first update condition related to the transmission power control variable is satisfied.

[0112] For example, when the processor (300) receives a power control signal from the network through the communication circuit (310), the processor (300) may update the first transmission power control variable and / or the second transmission power control variable based on the power control signal. For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal. For example, the second transmission power control variable may be decreased or maintained based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal when a specified first update condition related to the transmission power control variable is satisfied, and an increase based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal may be limited.

[0113] For example, if the second transmission power control variable updated (e.g., maintained or decreased) based on the power control signal is smaller than the reference transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the reference transmission power control variable. For example, the second transmission power control variable may be additionally updated to the same value as the reference transmission power control variable. For example, the reference transmission power control variable may include an average value of the first transmission power control variable confirmed during a specified second time period prior to a time point at which a specified first update condition related to the transmission power control variable is determined to be satisfied.

[0114] For example, if the processor (300) determines that the difference value between the first transmission power control variable updated based on the power control signal and the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable satisfies a designated second update condition related to the transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the first transmission power control variable and the designated third reference value. For example, a state of satisfying the designated second update condition related to the transmission power control variable may include a state in which the difference value between the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable and the first transmission power control variable exceeds the designated third reference value. For example, the second transmission power control variable may be additionally updated (or set) based on the difference value between the first transmission power control variable and the designated third reference value.

[0115] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may transmit at least one signal (or data) to a network (or network device) based on a transmission power control variable (e.g., a second transmission power control variable) that is selectively updated based on a power control signal obtained from a network, at operation 409. For example, the processor (300) may set (or update) the transmission power of the electronic device (101) based on the second transmission power control variable that is selectively updated based on the power control signal obtained from the network. The processor (300) may control the communication circuit (310) to transmit at least one signal (or data) to the network (or network device) at the transmission power that is set (or updated) based on the second transmission power control variable.

[0116] According to one embodiment, if the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines that the specified first update condition related to the transmission power control variable is not satisfied (e.g., 'No' in operation 405), the electronic device may terminate one embodiment for controlling the transmission power. For example, if the processor (300) determines that the specified first update condition related to the transmission power control variable is not satisfied, the electronic device (101) may set (or update) the transmission power based on a transmission power control variable (e.g., a first transmission power control variable) set (or updated) based on a power control signal.

[0117] According to one embodiment, the electronic device (101) can dynamically set reference values ​​associated with a specified first update condition related to a transmission power control variable based on a channel status with a network. For example, the reference values ​​associated with the specified first update condition related to the transmission power control variable can include at least one of a specified number for setting a power mode setting variable, a specified first reference value for determining a specified first update condition related to the transmission power control variable, or a specified third reference value for determining whether to update a second transmission power control variable.

[0118] FIG. 5 is a flowchart (500) for verifying whether a specified first update condition related to a transmission power control variable is satisfied in an electronic device according to one embodiment. For example, at least a portion of FIG. 5 may include detailed operations of operation 405 of FIG. 4 . In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 5 may be the electronic device (101) of FIG. 1 , FIG. 2 , or FIG. 3 .

[0119] According to one embodiment referring to FIG. 5, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or FIG. 2 or processor (300) of FIG. 3) is connected to a network, in operation 501, at least one of a channel state or a channel change rate with the network can be periodically or continuously checked.

[0120] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may determine, in operation 503, whether a channel state with a network satisfies a specified channel state condition. For example, the processor (300) may determine whether a most recently identified channel state with a network or an average of channel states with networks identified over a specified third period of time satisfies a specified channel state condition. For example, a state that satisfies a specified channel state condition may include a state in which the most recently identified channel state or an average of channel states with networks identified over a specified third period of time is greater than or equal to a specified reference channel state (e.g., a medium field and / or a high field). For example, a state that does not satisfy a specified channel state condition may include a state in which the most recently identified channel state or an average of channel states with networks identified over a specified third period of time is less than a specified reference channel state (e.g., a weak field and / or a medium field).

[0121] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) determines that a channel state with a network satisfies a specified channel state condition (e.g., 'Yes' in operation 503), in operation 505, the processor may determine whether a channel change rate with the network satisfies the specified channel change condition. For example, the processor (300) may determine whether a channel change rate with the network measured periodically or continuously for a specified first time period satisfies the specified channel change condition. For example, a state in which the specified channel change condition is satisfied may include a state in which the channel change rate with the network measured periodically or continuously for a specified first time period is lower than a specified reference change rate. For example, a state in which the specified channel change condition is not satisfied may include a state in which the channel change rate with the network measured periodically or continuously for a specified first time period is greater than or equal to a specified reference change rate.

[0122] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) determines that a channel change rate with a network satisfies a specified channel change condition (e.g., 'Yes' in operation 505), in operation 507, it may determine whether a power mode setting variable exceeds a specified first reference value. For example, the power mode setting variable may include an accumulated value (or sum) of variables for controlling transmission power included in a specified number of signals for increasing or decreasing transmission power received at a point in time prior to the current point in time among power control signals received from the network.

[0123] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may determine, in operation 509, that a specified first update condition related to a transmission power control variable is satisfied when a power mode setting variable exceeds a specified first reference value (e.g., 'Yes' in operation 507). For example, the processor (300) may determine, in operation 509, that a specified first update condition related to a transmission power control variable is satisfied when a channel state with a network satisfies a specified channel state condition, a channel change rate with the network satisfies a specified channel change condition, and the power mode setting variable exceeds a specified first reference value.

[0124] According to one embodiment, when the electronic device (101) determines that a specified first update condition related to the transmission power control variable is satisfied, the electronic device (101) may set (or determine) the transmission power of the electronic device (101) based on a transmission power control variable (e.g., a second transmission power control variable) that is optionally updated based on a power control signal received from a network (or a network device).

[0125] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) may determine, in operation 511, that the specified first update condition related to the transmission power control variable is not satisfied when the channel state with the network does not satisfy the specified channel state condition (e.g., 'No' in operation 503), the channel change rate with the network does not satisfy the specified channel change condition (e.g., 'No' in operation 505), or the power mode setting variable is less than or equal to the specified first reference value (e.g., 'No' in operation 507).

[0126] According to one embodiment, if the electronic device (101) determines that a specified first update condition related to a transmission power control variable is not satisfied, the electronic device (101) may set (or determine) the transmission power of the electronic device (101) based on a transmission power control variable (e.g., a first transmission power control variable) that is updated based on a power control signal received from a network (or a network device).

[0127] According to one embodiment, the electronic device (101) may check whether a channel state with a network satisfies a specified channel state condition to determine whether a specified first update condition related to a transmission power control variable is satisfied (e.g., operation 503 of FIG. 5), whether a channel change rate with the network satisfies a specified channel change condition (e.g., operation 505 of FIG. 5), and whether a power mode setting variable exceeds a specified first reference value (e.g., operation 507 of FIG. 5). However, the order of the operations of checking whether a channel state with a network satisfies a specified channel state condition to determine whether a specified first update condition related to a transmission power control variable is satisfied (e.g., operation 503 of FIG. 5), checking whether a channel change rate with the network satisfies a specified channel change condition (e.g., operation 505 of FIG. 5), and checking whether a power mode setting variable exceeds a specified first reference value (e.g., operation 507 of FIG. 5) may be varied or performed in parallel.

[0128] According to one embodiment, the electronic device (101) can determine whether a specified first update condition related to a transmission power control variable is satisfied based on at least one of a channel state with the network, a channel change rate with the network, or a power mode setting variable.

[0129] FIG. 6 is a flowchart (600) for updating a transmission power control variable in an electronic device according to one embodiment, while satisfying a specified first update condition related to the transmission power control variable. For example, at least a portion of FIG. 6 may include detailed operations of operations 405 to 409 of FIG. 4. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 6 may be the electronic device (101) of FIG. 1, FIG. 2, or FIG. 3.

[0130] According to one embodiment referring to FIG. 6, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) is connected to a network, in operation 601, the processor (300) may determine whether a specified first update condition related to a transmission power control variable is satisfied while connected to the network. For example, the processor (300) may determine whether a specified first update condition related to a transmission power control variable is satisfied based on operations 501 to 511 of FIG. 5.

[0131] For example, the processor (300) may determine whether a specified first update condition related to a transmission power control variable is satisfied based on at least one of a channel state with the network, a channel change rate with the network, or a power mode setting variable.

[0132] For example, the processor (300) may determine that a specified first update condition related to a transmission power control variable is satisfied when a channel state with a network satisfies a specified channel state condition, a channel change rate with the network satisfies a specified channel change condition, and a power mode setting variable exceeds a specified first reference value.

[0133] For example, the processor (300) may determine that a specified first update condition related to a transmission power control variable is not satisfied when a channel state with a network does not satisfy a specified channel state condition, a channel change rate with a network does not satisfy a specified channel change condition, or a power mode setting variable is less than or equal to a specified first reference value.

[0134] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) determines that a specified first update condition related to a transmission power control variable is not satisfied (e.g., 'No' in operation 601), the processor may terminate an embodiment for controlling transmission power while satisfying the specified first update condition related to the transmission power control variable. For example, when the processor (300) determines that the specified first update condition related to the transmission power control variable is not satisfied, the processor may set (or update) the transmission power of the electronic device (101) based on the first transmission power control variable set (or updated) based on the power control signal. For example, when the processor (300) determines that the specified first update condition related to the transmission power control variable is not satisfied, the processor (300) may continuously or periodically check whether the specified first update condition related to the transmission power control variable is satisfied while maintaining a connection with a network.

[0135] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) determines that a specified first update condition related to a transmission power control variable is satisfied (e.g., 'Yes' in operation 601), in operation 603, the processor may set a reference transmission power control variable. For example, the processor (300) may set an average value of a first transmission power control variable confirmed during a specified second time period prior to a time point at which the processor (300) determines that the specified first update condition related to the transmission power control variable is satisfied as the reference transmission power control variable.

[0136] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may determine, at operation 605, whether a power control signal (e.g., a TPC command) is received from a network.

[0137] According to one embodiment, when an electronic device (e.g., electronic device 101) or a processor (e.g., processor 120 or 300) receives a power control signal from a network (e.g., 'Yes' in operation 605), in operation 607, the processor may update a first transmission power control variable and / or a second transmission power control variable based on the power control signal. For example, when the processor 300 determines that a specified first update condition related to the transmission power control variable is satisfied, the processor may check whether a second transmission power control variable that operates independently of the first transmission power control variable exists. For example, when the processor 300 determines that the second transmission power control variable does not exist, the processor 300 may generate a second transmission power control variable corresponding to the first transmission power control variable to set the transmission power of the electronic device 101. For example, the second transmission power control variable may include the same value as the first transmission power control variable as an initial value. For example, the operation of generating a second transmission power control variable may be omitted if the processor (300) determines that the second transmission power control variable exists.

[0138] For example, when the processor (300) receives a power control signal from the network through the communication circuit (310), the processor (300) may update the first transmission power control variable and / or the second transmission power control variable based on the power control signal. For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal. For example, the second transmission power control variable may be decreased or maintained based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal when a specified first update condition related to the transmission power control variable is satisfied, and an increase based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal may be limited.

[0139] For example, if the second transmission power control variable updated (e.g., maintained or decreased) based on the power control signal is less than the reference transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the reference transmission power control variable. For example, the second transmission power control variable may be additionally updated to the same value as the reference transmission power control variable.

[0140] For example, if the processor (300) determines that the difference value between the first transmission power control variable updated based on the power control signal and the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable satisfies a designated second update condition related to the transmission power control variable, the processor (300) may additionally update the second transmission power control variable based on the first transmission power control variable and the designated third reference value. For example, a state of satisfying the designated second update condition related to the transmission power control variable may include a state in which the difference value between the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable and the first transmission power control variable exceeds the designated third reference value. For example, the second transmission power control variable may be additionally updated (or set) to a value obtained by subtracting the designated third reference value from the first transmission power control variable.

[0141] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may transmit at least one signal (or data) to a network (or a network device) based on a second transmission power control variable, at operation 609. For example, the processor (300) may set (or update) the transmission power of the electronic device (101) based on a second transmission power control variable that is selectively updated based on a power control signal obtained from the network. The processor (300) may control the communication circuit (310) to transmit at least one signal (or data) to the network (or the network device) at the transmission power set (or updated) based on the second transmission power control variable. As an example, the transmission power of the electronic device (101) may include power used by the electronic device (101) to transmit at least one of a signal or data to the network.

[0142] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may terminate an embodiment for controlling transmission power in a state in which a specified first update condition related to a transmission power control variable is satisfied when a power control signal is not received from a network (e.g., 'No' in operation 605). For example, the processor (300) may continuously or periodically check whether a power control signal is received from the network while connected to the network. For example, when the processor (300) receives a power control signal from the network, the processor (300) may update the first transmission power control variable and / or the second transmission power control variable based on the power control signal (e.g., operation 607).

[0143] FIG. 7 is a flowchart (700) for updating a second transmission power control variable based on a power control signal in an electronic device according to one embodiment. For example, at least a portion of FIG. 7 may include detailed operations of operation 407 of FIG. 4 or operation 607 of FIG. 6 . In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 7 may be the electronic device (101) of FIG. 1 , FIG. 2 , or FIG. 3 .

[0144] According to one embodiment referring to FIG. 7, when an electronic device (e.g., electronic device 101) or a processor (e.g., processor 120 of FIG. 1 or 2 or processor 300 of FIG. 3) receives a power control signal from a network (e.g., 'Yes' of operation 605 of FIG. 6), in operation 701, the processor (300) may determine whether to reduce a second transmission power control variable based on the power control signal. For example, when the power control signal received from the network includes a variable (e.g., -1) for reducing the transmission power of the electronic device (101), the processor (300) may determine to reduce the second transmission power control variable. For example, when the power control signal received from the network includes a variable (e.g., 0, 1, or 3) for maintaining or increasing the transmission power of the electronic device (101), the processor (300) may determine not to reduce the second transmission power control variable.

[0145] According to one embodiment, if the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines not to decrease the second transmission power control variable based on the power control signal (e.g., 'NO' in operation 701), the processor (300) may terminate the embodiment for updating the second transmission power control variable. For example, the processor (300) may maintain the second transmission power control variable if the power control signal received from the network includes a variable for maintaining the transmission power of the electronic device (101) (e.g., 0). For example, the processor (300) may also maintain the second transmission power control variable if the power control signal received from the network includes a variable for increasing the transmission power of the electronic device (101) (e.g., 1 or 3).

[0146] According to one embodiment, if the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines to decrease the second transmission power control variable based on the power control signal (e.g., 'Yes' in operation 701), then in operation 703, the processor (300) may update the second transmission power control variable. For example, the processor (300) may decrease the second transmission power control variable by a specified value (e.g., -1) based on the power control signal.

[0147] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may determine, at operation 705, whether a second transmit power control variable updated (e.g., decreased) based on a power control signal is less than a reference transmit power control variable.

[0148] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) may update the second transmission power control variable based on the reference transmission power control variable in operation 707 when the second transmission power control variable updated (e.g., decreased) based on the power control signal is less than the reference transmission power control variable (e.g., 'Yes' in operation 705). For example, the processor (300) may update the second transmission power control variable to a value equal to the reference transmission power control variable when the second transmission power control variable updated (e.g., maintained or decreased) based on the power control signal is less than the reference transmission power control variable.

[0149] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) may terminate one embodiment for updating the second transmit power control variable if the updated (e.g., decreased) second transmit power control variable based on the power control signal is greater than or equal to the reference transmit power control variable (e.g., 'No' in operation 705).

[0150] FIG. 8 is a flowchart (800) for updating a second transmission power control variable based on a first transmission power control variable in an electronic device according to one embodiment. For example, at least a portion of FIG. 8 may include detailed operations of operation 407 of FIG. 4 or operation 607 of FIG. 6. In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 8 may be the electronic device (101) of FIG. 1, FIG. 2, or FIG. 3.

[0151] According to one embodiment referring to FIG. 8, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) receives a power control signal from a network (e.g., 'Yes' of operation 605 of FIG. 6), in operation 801, the electronic device may update a first transmission power control variable and / or a second transmission power control variable based on the power control signal. For example, the processor (300) may update the first transmission power control variable based on the power control signal received from the network. For example, the first transmission power control variable may be decreased when the power control signal received from the network includes a variable (e.g., -1) for decreasing the transmission power of the electronic device (101). For example, the first transmission power control variable may be maintained when the power control signal received from the network includes a variable (e.g., 0) for maintaining the transmission power of the electronic device (101). For example, the first transmission power control variable may be increased when the power control signal received from the network includes a variable (e.g., 1 or 3) for increasing the transmission power of the electronic device (101).

[0152] For example, the processor (300) may selectively update the second transmission power control variable based on a power control signal received from the network when a specified first update condition related to the transmission power control variable is satisfied. For example, the second transmission power control variable may be decreased when the power control signal received from the network includes a variable (e.g., -1) for decreasing the transmission power of the electronic device (101) while the specified first update condition related to the transmission power control variable is satisfied. For example, the second transmission power control variable may be maintained when the power control signal received from the network includes a variable (e.g., 0) for maintaining the transmission power of the electronic device (101) while the specified first update condition related to the transmission power control variable is satisfied. For example, the second transmission power control variable may be maintained if the power control signal received from the network includes a variable (e.g., 1 or 3) for increasing the transmission power of the electronic device (101) while satisfying a specified first update condition related to the transmission power control variable. For example, the second transmission power control variable may be limited from increasing based on a power control signal received from the network while satisfying a specified first update condition related to the transmission power control variable.

[0153] For example, if the second transmission power control variable updated (e.g., maintained or decreased) based on the power control signal is less than the reference transmission power control variable, the processor (300) may additionally update the second transmission power control variable to the same value as the reference transmission power control variable.

[0154] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may, at operation 803, determine a difference value between a first transmission power control variable updated based on a power control signal and a second transmission power control variable updated based on the power control signal and / or a reference transmission power control variable.

[0155] According to one embodiment, an electronic device (e.g., electronic device 101) or a processor (e.g., processor 120 or 300) may determine, at operation 805, whether a difference value between a first transmission power control variable and a second transmission power control variable satisfies a specified second update condition associated with the transmission power control variable. For example, the processor (300) may determine that the specified second update condition associated with the transmission power control variable is satisfied if the difference value between the first transmission power control variable and the second transmission power control variable exceeds a specified third reference value. For example, the processor (300) may determine that the specified second update condition associated with the transmission power control variable is not satisfied if the difference value between the first transmission power control variable and the second transmission power control variable is less than or equal to the specified third reference value.

[0156] According to one embodiment, if the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines that the difference value of the first transmission power control variable and the second transmission power control variable does not satisfy a specified second update condition associated with the transmission power control variable (e.g., 'No' in operation 805), the processor (300) may terminate the embodiment for updating the second transmission power control variable. For example, the processor (300) may maintain the updated second transmission power control variable based on the power control signal and / or the reference transmission power control variable.

[0157] According to one embodiment, when the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines that the difference value between the first transmission power control variable and the second transmission power control variable satisfies a specified second update condition related to the transmission power control variable (e.g., 'Yes' in operation 805), in operation 807, the processor may additionally update the second transmission power control variable based on the first transmission power control variable. For example, when the difference value between the first transmission power control variable updated based on the power control signal and the second transmission power control variable updated based on the power control signal and / or the reference transmission power control variable exceeds a specified third reference value, the processor (300) may additionally update the second transmission power control variable based on the first transmission power control variable and the specified third reference value. For example, the second transmission power control variable may be additionally updated (or set) to a value obtained by subtracting a third reference value specified in the first transmission power control variable.

[0158] FIG. 9 is a flowchart (900) for updating a transmission power control variable in an electronic device according to one embodiment, while satisfying a specified third update condition related to the transmission power control variable. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 9 may be the electronic device (101) of FIG. 1, FIG. 2, or FIG. 3.

[0159] According to one embodiment referring to FIG. 9, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) may, in operation 901, set the transmission power of the electronic device (101) based on a second transmission power control variable while satisfying a specified first update condition related to the transmission power control variable. For example, when there is at least one signal (or data) to be transmitted to a network (or network device), the processor (300) may control the communication circuit (310) to transmit at least one signal (or data) to the network (or network device) at the transmission power set (or updated) based on the second transmission power control variable.

[0160] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may, at operation 903, determine whether a specified third update condition related to a transmission power control variable is satisfied. For example, the processor (300) may continuously or periodically check at least one of a channel state or a channel change rate with the network while connected to a network. For example, if the channel state with the network does not satisfy the specified channel state condition, the processor (300) may determine that the specified third update condition related to the transmission power control variable is satisfied. For example, if the channel change rate with the network does not satisfy the specified channel change condition, the processor (300) may determine that the specified third update condition related to the transmission power control variable is satisfied. For example, if the power mode setting variable is less than or equal to a specified second reference value, the processor (300) may determine that the specified third update condition related to the transmission power control variable is satisfied.

[0161] For example, the processor (300) may determine that a specified third update condition related to a transmission power control variable is not satisfied when a channel state with a network satisfies a specified channel state condition, a channel change rate with the network satisfies a specified channel change condition, and a power mode setting variable exceeds a specified second reference value.

[0162] According to one embodiment, when the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) determines that the specified third update condition related to the transmission power control variable is not satisfied (e.g., 'No' in operation 903), the processor may terminate one embodiment for updating the transmission power control variable while satisfying the specified third update condition related to the transmission power control variable. For example, when the processor (300) determines that the specified third update condition related to the transmission power control variable is not satisfied, the processor may set (or update) the transmission power of the electronic device (101) based on a second transmission power control variable that is optionally updated based on a power control signal received from the network. For example, when the processor (300) is maintained connected to the network while satisfying the specified first update condition related to the transmission power control variable, the processor (300) may continuously or periodically check whether the specified third update condition related to the transmission power control variable is satisfied.

[0163] According to one embodiment, if the electronic device (e.g., electronic device (101)) or processor (e.g., processor (120 or 300)) determines that a specified third update condition related to a transmit power control variable is satisfied (e.g., 'Yes' in operation 903), then, in operation 905, it may determine whether a power control signal is received from the network.

[0164] According to one embodiment, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) receives a power control signal from a network (e.g., 'Yes' in operation 905), in operation 907, the electronic device may update the first transmission power control variable and the second transmission power control variable based on the power control signal.

[0165] For example, when the processor (300) receives a power control signal from the network through the communication circuit (310), the processor (300) may update the first transmission power control variable and the second transmission power control variable based on the power control signal. For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal. For example, the second transmission power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling transmission power included in the power control signal when a specified third update condition related to the transmission power control variable is satisfied.

[0166] For example, if the second transmission power control variable updated based on the power control signal is smaller than the minimum transmission power control variable, the processor (300) may update the second transmission power control variable to a value equal to the minimum transmission power control variable. For example, the minimum transmission power control variable may include the minimum value of the transmission power control variable for the electronic device (101) to maintain connection with the network.

[0167] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may set (or update) the transmission power of the electronic device (101) based on a second transmission power control variable at operation 909. For example, the transmission power of the electronic device (101) may be used by the electronic device (101) to transmit at least one signal or data to a network. For example, when there is at least one signal (or data) to be transmitted to a network (or a network device), the processor (300) may control the communication circuit (310) to transmit at least one signal (or data) to the network (or the network device) at the transmission power set (or updated) based on the second transmission power control variable.

[0168] According to one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may terminate an embodiment for updating a transmission power control variable in a state in which a designated third update condition related to the transmission power control variable is satisfied when a power control signal is not received from the network (e.g., 'No' in operation 905). For example, the processor (300) may continuously or periodically check whether a power control signal is received from the network while connected to the network. For example, when the processor (300) receives a power control signal from the network, the processor (300) may update the first transmission power control variable and the second transmission power control variable based on the power control signal (e.g., operation 907).

[0169] According to one embodiment, the electronic device (101) can dynamically set reference values ​​associated with a designated third update condition related to a transmission power control variable based on a channel status with the network. For example, the reference values ​​associated with the designated third update condition related to the transmission power control variable can include at least one of a designated number for setting a power mode setting variable, a designated second reference value for determining a designated third update condition related to the transmission power control variable, or a designated third reference value for determining whether to update the second transmission power control variable.

[0170] FIG. 10 is a flowchart (1000) for updating a second transmission power control variable in an electronic device according to one embodiment when a specified third update condition related to the transmission power control variable is satisfied. For example, at least a portion of FIG. 10 may include detailed operations of operation 907 of FIG. 9. In the following embodiments, the respective operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the respective operations may be changed, and at least two operations may be performed in parallel. For example, the electronic device of FIG. 10 may be the electronic device (101) of FIG. 1, FIG. 2, or FIG. 3.

[0171] According to one embodiment referring to FIG. 10, when an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120) of FIG. 1 or 2 or processor (300) of FIG. 3) receives a power control signal from a network while satisfying a designated third update condition related to a transmission power control variable (e.g., 'Yes' of operation 905 of FIG. 9), in operation 1001, the electronic device may update a first transmission power control variable and a second transmission power control variable based on the power control signal. For example, when the processor (300) receives a power control signal from the network through the communication circuit (310), the processor (300) may update the first transmission power control variable and the second transmission power control variable based on the power control signal. For example, the first transmission power control variable may be decreased, maintained, or increased based on a variable for controlling transmission power included in the power control signal (e.g., -1, 0, 1, or 3). For example, the second transmit power control variable may be decreased, maintained, or increased based on a variable (e.g., -1, 0, 1, or 3) for controlling the transmit power included in the power control signal, if a specified third update condition related to the transmit power control variable is satisfied.

[0172] In one embodiment, an electronic device (e.g., electronic device (101)) or a processor (e.g., processor (120 or 300)) may, in operation 1003, determine whether a second transmission power control variable updated based on a power control signal is less than a specified update reference value. For example, the specified update reference value may include a minimum value of a transmission power control variable for the electronic device (101) to maintain a connection with a network (e.g., a minimum transmission power control variable).

[0173] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) may terminate an embodiment for updating the second transmission power control variable while satisfying a specified third update condition related to the transmission power control variable if the second transmission power control variable updated based on the power control signal is greater than or equal to a specified update reference value (e.g., 'No' in operation 1003). For example, the processor (300) may maintain the second transmission power control variable updated based on the power control signal.

[0174] According to one embodiment, the electronic device (e.g., electronic device (101)) or the processor (e.g., processor (120 or 300)) may update the second transmission power control variable based on the specified update reference value in operation 1005 when the second transmission power control variable updated based on the power control signal is less than the specified update reference value (e.g., 'Yes' in operation 1003). For example, the processor (300) may update the second transmission power control variable to the specified update reference value when the second transmission power control variable updated based on the power control signal is less than the specified update reference value (e.g., the minimum transmission power control variable).

[0175] According to one embodiment, when the electronic device (101) determines that the specified first update condition related to the transmission power control variable is satisfied while the specified third update condition related to the transmission power control variable is satisfied, the electronic device (101) may set (or update) the transmission power of the electronic device (101) based on a transmission power control variable (e.g., a second transmission power control variable) that is selectively updated based on a power control signal received from the network. For example, the processor (300) may set (or update) the transmission power of the electronic device (101) based on operations 601 to 609 of FIG. 6 .

[0176] According to one embodiment, when the second transmission power control variable exists in a state of being connected to a network, the electronic device (101) may set (or update) the transmission power of the electronic device (101) based on the second transmission power control variable while the connection between the electronic device (101) and the network is maintained. For example, the state in which the connection between the electronic device (101) and the network is maintained may include at least one of a state in which an RRC state with the network is maintained as an RRC connection state or a state in which a PUSCH configuration by the network is maintained.
